Abstract

 â€‹Advances in the controlled growth and characterization of high–quality nanomaterials have been the key enablers in establishing the basis of modern applications of such materials in electronics and live science. The development of a new generation of smart nanosized materials requires the corresponding knowledge. One of the most prominent applications of nanotechnology is the design of matter on an atomic, molecular, and supramolecular scale. The most well-known description of nanotechnology was established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. The impact of nanotechnology extends from its medical, ethical, mental, legal and environmental applications, to fields such as engineering, medicine, chemistry, computing and materials-science. During this lecture we will focus on various nanoparticles prepared by physical and wet chemistry methods and their applications depending on their unusual properties such size, morphology, electronic structures and biocompatibility.

Abstract

Chemotherapy is one of most common cancer treatments in clinics. In most cases, the clinical responses show that the efficacy of chemotherapy is limited by the development of multidrug resistance (MDR) in cancer cells during a long period of treatment. Target-specific delivery and sustained release of anticancer agents and siRNA has attracted considerable research interest in cancer chemotherapy. It is clear that the single treatment by either anticancer drug or siRNA delivered by nanocarriers can only achieve limited success in overcoming the MDR of cancer cells. Thus, the development of an effective strategy to overcome the multidrug resistance in chemotherapy remains a major challenge in the treatment of cancers, where co-delivery of anticancer drugs and siRNA would be a promising strategy.

Recently, hierarchical nanocomposites have attracted great interests in bioapplications such as drug delivery, biomedical imaging, biochemical sensing and biocatalysts owing to their structure features and unique properties.1 In our group, we have developed hierarchical SiO2@MgAl-layered double hydroxide nanocomposites (SiO2@MgAl-LDH) with various functional groups (-NH2, -SH, -PEG) via nanodot-coating strategy. These nanocomposites have showed enhanced siRNA and drug delivery to cancer cells. The functional SiO2@MgAl-LDH nanocomposites retained the layered structure and plate-like morphology as MgAl-LDH NPs. Moreover, functional SiO2@MgAl-LDH showed good dispersion in aqueous solution and cell culture medium. The in vitro tests have demonstrated anticancer drugs or siRNA delivered by functional SiO2@MgAl-LDH apparently inhibited the cancer cell growth.2. 3

Abstract

Dendrimers are highly branched organic macromolecules with successive layers or generations of branch units surrounding a central core. Organic, inorganic hybrid versions have also been produced by trapping metal ions or metal clusters within the voids of the dendrimers. Their unusual, tree like topology endows these nano meter sized macromolecules with a gradient in branch density from the interior to the exterior, which can be exploited to direct the transfer of charge and energy from the dendrimer periphery to its core.

Here, we show that many metalharides more than 50 as a Lewis acid such as SnCl2 and FeCl3, complex to the imines groups of a spherical poly (phenyl azomethine) dendrimer in a stepwise fashion according to an electron gradient with complexation in a more peripheral generation proceeding only after complexation in generations closer to the core has been completed. By attaching an electron withdrawing group to the dendrimer core, we are able to change the complexation pattern, so that the core imines are complexed last. By further extending this strategy, it should be possible to control the number and location of metal ions incorporated into dendrimer structures, which might and uses as tailored catalysts or fine controlled clusters for advanced nano catalysts.

We show that, many metalharides complex to the imines groups of a asymmetric poly (phenyl azomethine) dendrimer with pyridine unit at the core in a stepwise fashion according to an electron gradient, which shows 8 changes in isobestic points during the titration complexation(Figure). The multi-metal assembly in a discrete molecule can be converted to a size regulated multi-metallic clusters with a size smaller than 1 nm using as a dendrimer molecular reactor. Due to the well-defined number of multi-metallic clusters in the sub nanometer size region as a new sbstance, we expect that their properties are much different from that of bulk or general metal nanoparticles.

 

Biography

Ming B Yu has graduated from Jilin University, China in 1961. He worked as a Lecturer in Zhengzhou Coal Managing College, China, and a Visiting Adjunct Lecturer in University of Georgia, USA. Currently, he is a Retiree and still active in the study of condensed matter physics: vibrations in low-dimensional lattices, etc. and statistical physics: transport equations, entropy variation, Lyapunov exponents, etc. of closed and open nonequilibrium systems. He has published more than 20 research papers in reputed journals as well as a monograph in the areas mentioned above

Abstract

A nonequilibrium system is studied in the framework of time-dependent projection operator. A macroscopic state space is introduced to describe macroscopic states of the system which is spanned by averages of a set of independent basic variables of the system. The entropy variation rate is derived as the average trace of Jacobian matrix of transport equations of the system. They are a set of nonlinear differential-integral equations. The Jacobian matrix is a sum of frequency matrix and memory matrix. Because the former is traceless, the entropy variation is contributed only by the average trace of an entropy source matrix which is a term in the memory matrix. The entropy variation and Lyapunov exponents of the system are shown determined by the non-uniformity in time and in the macro-state space of fluctuation forces associated with each basic variable of the system. This indicates a fundamental relationship between fluctuations and dissipation. It is proved that if the dynamic system defined by the transport equations is ergodic, the sum of Lyapunov exponents is equal to the time-rate of the entropy or average trace of the entropy source matrix. The study is illustrated by a one-component incompressible fluid.

Abstract

The uncontrolled release of nutrients in aquatic environments globally and the resulting effects of eutrophication and excessive algae growth. Biopolymer flocculants and adsorbents offer a unique green chemistry strategy for the controlled removal of oxyanion species in water and wastewater due to their molecular tunability and sustainability. In the case of solid-liquid treatment systems, the use of chemical additives and occurence of secondary pollution is reduced relative to conventional treatment methods.This presentation will provide an overview of research progress at the University of Saskatchewan (U of S) related to the materials design and characterization of biopolymer platforms as adsorbent materials for uptake of environmentally relevant anions. In particular, case studies of sorbents with high affinity toward oxyanion species are described, where synthetic modification of biopolymers reveals enhanced physicochemical properties related to adsorption and responsive behaviour to external stimuli (pH, ionic strength, temperature, etc). Sustainable materials that show reversible adsorption–desorption processes and high efficiency Pi removal using green chemistry (surface functionalization, cross-linking, and composite formation). This research is anticipated to contribute advanced functional materials for oxyanion waterborne contaminants for controlled removal and targeted water treatment processes.

Abstract

Microbial biofilm has become a significant problems in biomedical applications, leading to the significant loss in human health and economy. In particular, extracellular polymeric substances (EPS) in microbial biofilm is the rigid protective layers for microbial persistence and resistance against the antimicrobial treatment. This problem sometimes causes the complete removal of infection sites or organs. In the recent development of nanotechnology, stimuli-activated nanotechnology-based treatments can be used to treat the microbial biofilm infections. In this study, biocompatible liquid metals (LM) such as Galinstan (GaInSn) functionalised with magnetic iron particles are investigated as a new class of stimuli activated biofilm treatment. Particularly, Galinstan nanoparticles magnetically functionalised with low-weight ratio magnetic iron (Fe) inclusions are exploited as magnetic responsive materials. When exposed to a rotating magnetic field these particles move at high speeds and undergo a shape transformation from spheres to high aspect ratios rods, irregular spheroids, and “nano-stars” which can physically rupture and remove pathogenic bacteria from a model surface. The magneto-physical antibacterial activity of these LM particles is tested against a range of single and co-colonised infectious biofilms of common pathogens (Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli). Furthermore, the concentration of the magnetic Fe inclusion was varied in an effort to optimise the rate of antibacterial efficacy. This approach has paved the innovative way to treat the biofilm-related infections for the future applications.

Abstract

Graphene-based materials such as carbon nanotube and graphene sheet itself have a wide range of possible applications. Among these graphene-based materials, 3-dimensional (3D) graphene network with large surface area could be promising material as a platform for electrochemical and bio applications. This kind of carbon nanostructure is called as carbon nanowalls (CNWs), carbon nanoflakes, carbon nanosheets, graphene nanosheets and graphene nanowalls. CNWs and similar materials are basically self-supported network of few-layer graphenes standing almost vertically on the substrate to form 3D structure. CNWs can be synthesized by plasma-enhanced chemical vapour deposition (PECVD) on heated substrates (600-800 °C) employing methane and hydrogen mixtures. The height of CNWs increases almost linearly with the growth period, while the thickness of each sheet and interspaces between adjacent sheets are almost constant. CNWs are sometimes decorated with nanoparticles and biomolecules. The maze-like architecture of CNWs with large-surface-area graphene planes would be useful as electrodes for energy storage devices and scaffold for cell culturing. Especially, combined with surface functionalization including surface termination and decoration with nanoparticles and biomolecules, CNWs can be suitable as platform in electrochemical and biosensing applications. We have carried out CNW growth using several PECVD techniques. Moreover, graphene surface was decorated with Pt nanoparticles by the reduction of chloroplatinic acid. We also report the performances of hydrogen peroxide sensor and fuel cell, where CNW electrode was used. Electrochemical experiments demonstrate that CNWs offer great promise for providing a new class of nanostructured electrodes for electrochemical sensing, biosensing and energy conversion applications.

Kadhim Al sahlani is a PhD student at School of Engineering, The University of Newcastle. He is working in Metal syntactic foam, manufacturing and characterization. He has published three papers in reputed journals

Abstract

Metal foams are a novel class of lightweight materials with unique properties. Metal syntactic foams (MSF) are manufactured by embedding hollow or porous lightweight particles in a metal matrix. Recently developed MSF have received great attention because they have the potential to replace a broad range of polymeric, ceramics and metallic foams due to their superior properties like remarkably specific strength, controlled energy absorption, brilliant damping and resistance to high temperatures and harsh conditions. Matrix properties, physical properties of filler materials, e.g. particle size and geometry, volume fraction of fillers and secondary processes e.g. heat treatment are the major parameters that strongly affect the mechanical properties of MSF. In spite of intensive research studies on MSF, cost, high density and relatively high strength are remaining the main challenges which limit the broad application of these materials. The aim of this work is to broaden the circle of MSF by introducing new low density cost-effective filler and characterization of the produced foams. The first part of this study presents the manufacturing and basic physical characterisation of MSF made using a cost-effective expanded glass (EG) particle as the filler and A356 alloy as the matrix material. Expanded glass (EG) particles are made from fully recycled soda-lime glass and have a low bulk density (0.17- 0.26 g/cm3) due to 83% volume fraction of internal porosity. In this part, particle shrinkage was studied and has been utilized to increase the particles’ strength and tailor the mechanical properties of the expanded glass/metal syntactic foam (EG-MSF). The second part presents the effect of particle size on the microstructure and mechanical properties of EG-MSF.

Abstract

Modern electronics has advanced at a tremendous pace primarily due to enhanced performance of CMOS transistors due to dimension scaling, introduction of new materials and novel device structures. While scaling transistors increases their performance, opposite is true for scaling the copper/low-k interconnects that link these transistors. Looking into the future the relentless scaling paradigm is threatened by the limits of interconnects, including excessive power dissipation, insufficient communication bandwidth, and signal latency for both off-chip and on-chip applications. Many of these obstacles stem from the physical limitation of copper electrical wires, in particular, the increase in copper resistivity, as wire dimensions and grain size become comparable to the bulk mean free path of electrons in copper. Thus, it is imperative to examine alternate interconnect schemes and explore possible advantages of novel potential candidates: carbon nanotubes (CNT), graphene and optical interconnect. Simulations show that CNTs and graphene are advantageous for local interconnects due to their lower resistance, while optical interconnects are better suited for global, semi-global and off-chip interconnects. Ge and GeSn are emerging as viable candidate for Si compatible integration of optical components, laser, detectors and modulators. Three-dimensional (3-D) integration would be a possible way to integrate these on a Si based system on a chip (SoC). The 3-D technology offers the capability to build SoC by placing heterogeneous circuits in different layers, e.g., memory, logic, analog, sensors, wireless and optical I/O, etc. 3-D integration can reduce the chip area and thus improve chip performance by reducing interconnect length, thereby reducing the resistance and capacitance and thus enhance system performance. A review of these emerging interconnect technologies for nanoelectronics will be discussed.

Abstract

The interfacial properties play a crucial role in determining the performance of perovskite solar cells. We reported the effect of graphdiyne doped into both electron and hole transport layers of perovskite solar cells with an inverted structure based on MAPbI3. A peak power conversion efficiency beyond 20% was obtained with J-V hysteresis and stability remarkably improved. It reveals that the employment of doping graphdiyne not only brings out an increase of electrical conductivity, electron mobility, and charge extraction ability in the interfacial layers, but improves film morphology of the electron transport layers and reduces charge recombination which contribute to an enhanced fill factor. Later, we first employed certain amount of graphdiyne (25%) as a host material in perovskite solar cells, which is reported to successfully push the device efficiency up to 21.01%, achieving multiple collaborative effects of highly crystalline qualities, large domain sizes and few grain boundaries. Furthermore, the current-voltage hysteresis was neligible, and device stability was appreciably improved as well. It is found that graphdiyne, as the host active material, significantly affects the crystallization, film morphology and a series of optoelectronic properties of perovskite active layer, exhibiting promising applications in the field of solar cells. 
This study indicates that applying graphdiyne is a promising strategy to optimize the performance of perovskite solar cells.

Abstract

An experimental investigation was conducted on alkali activated kaolinite clay using sodium hydroxide solution. XRD analyses were conducted to determine the mineral composition of the mixture components. Also thermo-gravimetric analysis attenuated total reflectance-Fourier transform infrared spectroscopy and scanning electron microscopy techniques were used to investigate the microstructure of the alkali-activation products. The alkali activation of kaolinite with the NaOH alkaline solution produced a binding agent identified as hydroxysodalite phase (Na8Al6Si6O24 (OH)2·4H2O) when pure kaolinite was used. Mechanical strength of the produced polymer was evaluated on cylindrical specimens containing quartz sand as a filler material under dry and after 5, 10 and 20 F-T cycles. The recorded strength value of freshly produced samples was in the range of 35 MPa. Addition of 10% CKD resulted in strength increase to about 40 MPa (about 15% higher). Durability tests on samples without CKD showed a reduction in strength of 22% due to 20 F-T cycles, while specimens prepared with addition of 10% cement dust (CKD) showed less reduction of about 10% as a result of F-T cycles. The produced inorganic polymer could form a high strength environmentally friendly construction material. Addition of 10% CKD enhanced both the strength and durability of the produced inorganic polymer.

Abstract

Recently, 2D graphdiyne has shown many unique advantages for improving the performance of the electrochemical devices. The synthesis method of high-quality graphdiyne nanosheets is developed. Based on this method, all-carbon graphdine nanosheets can be used to protect the silicon nanoparticles and the metal oxides seamlessly, which are two typical lithium-ion battery anodes. 3D all-carbon mechanical and conductive networks with reasonable voids for the silicon and metal oxides can be constructed in situ. This method can effectively restrained their interfacial problems, which is induced by the disintegrations in the mechanical and conductive networks during the repeated volume variations. The as-prepared electrode shows impressive improvements regarding the capacity and performance retention. Furthermore, this method shows great promises in solving the key problems in other high-energy-density anodes.

Abstract

The electrical and thermal properties of the doped Tellurium Telluride (Tl10Te6) chalcogenide nano-particles are mainly characterized by a competition between metallic (hole doped concentration) and semi-conducting state. We have studied the effects of Sn doping on the electrical and thermoelectric properties of Tl10-xSnxTe6 (1.00 ≤x≤ 2.00), nano-particles, prepared by solid state reactions in sealed silica tubes and ball milling method. Structurally, all these compounds were found to be phase pure as confirmed by the x-rays diffractometery (XRD) and energy dispersive X-ray spectroscopy (EDS) analysis. Additionally crystal structure data were used to model the data and support the findings. The particles size was calculated from the XRD data by Scherrer’s formula. The EDS was used for an elemental analysis of the sample and declares the percentage of elements present in the system. The thermo-power or Seebeck co-efficient (S) was measured for all these compounds which show that S increases with increasing temperature from 295 to 550 K. The Seebeck coefficient is positive for the whole temperature range, showing p-type semiconductor characteristics. The electrical conductivity was investigated by four probe resistivity techniques revealed that the electrical conductivity decreases with increasing temperature, and also simultaneously with increasing Sn concentration. While for Seebeck coefficient the trend is opposite which is increases with increasing temperature. These increasing behavior of Seebeck coefficient leads to high power factor which are increases with increasing temperature and Sn concentration except For Tl8Sn2Te6 because of lowest electrical conductivity but its power factor increases well with increasing temperature.
