The purpose of this experiment was to investigate the visible imaging of gastric adenocarcinoma cells in vitro by targeting tumor-associated glycoprotein 72 (TAG-72) with near-infrared quantum dots (QDs). QDs with an emission wavelength of about 550 to 780 nm were conjugated to CC49 monoclonal antibodies against TAG-7…
Herein, we report a solid-state reduction process (in contrast to solution-based approach) by using an environmentally friendly reductant, such as vitamin C (denoted VC), to be directly employed to solid-state graphene oxide (GO) templates to give the highly active rGO architecture with a sheet resistance of as low as…
The main aim of the present work was to formulate anti-neoplastic drug loaded polymeric nanoparticles using biodegradable polymers (Chitosan and Eudragit RS 100) by emulsion droplet coalescence method. The model drug used here is 5-fluorouracil which is a pyrimidine analogue that is mainly used to treat colonic carcin…
A unified set of parameters and dynamic equations have been developed to describe the time-dependent surface voltage and currents measured for a broad range of electron transport experiments conducted in parallel plate geometry with a dielectric slab above a grounded electrode and with either a floating or fixed volta…
A kind of web-like carbon with interconnected nanoribbons was fabricated using bacterial cellulose pyrolyzed at various temperatures, and the microwave dielectric properties were investigated. Bacterial cellulose was converted into carbonized bacterial cellulose (CBC) with a novel three-dimensional web built of entang…
The effect of the temperature on the Crystal Size Distribution (CSD) in antisolvent crystallization operation, for systems where the solubility is weakly dependent on the temperature, is analyzed. The hydrogen bonding properties of the solvents used that influence the supersaturation of the solution and consequently t…
Sulfate-reducing bacteria (SRB) participate in microbially induced corrosion (MIC) of equipment and H2S-driven reservoir souring in oil field sites. Successful management of industrial processes requires methods that allow robust monitoring of microbial communities. This study investigated the applicability of denatur…
OBJECTIVES: This study intended to describe the development of two novel, biocompatible and potential surface hydroxylated quaternary ammonium chloride based poly(propylene imine) (PPI) dendrimers for effective delivery of the drug Norfloxacin (NFN). METHODS: The synthetic pathway involved the hydroxylation and methyl…
The key enzymes for poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) biosynthesis in haloarchaea have been identified except the β-ketothiolase(s), which condense two acetyl coenzyme A (acetyl-CoA) molecules to acetoacetyl-CoA, or one acetyl-CoA and one propionyl-CoA to 3-ketovaleryl-CoA. Whole-genome analysis has…
CeO‐CuO catalysts were prepared by citric acid method at different calcination temperatures. The purpose of this study is to investigate the influence of calcination temperature on the catalytic activity of CeO2‐CuO catalyst for the selective catalytic reduction of NO with NH3. As can be seen from the results, Ce‐Cu(4…
The specific thermal resistance values of several thermal interface materials (TIMs) intended to thermally enhance Cu contact pairs and their degradation under isothermal ageing at 170 °C have been investigated using Cu stack samples consisting of 10 Cu discs and 9 layers of the TIMs. The results obtained indicate tha…
Density functional theory (DFT) calculations are used to identify correlations among reactivity, structural stability, cohesion, size, and morphology of small Au clusters supported on stoichiometric and defective CeO 2 (111) surfaces. Molecular adsorption significantly affects the cluster morphology and in some cases…
ABSTRACT Polymeric biomaterials are widely used as carriers for cells and therapeutic agents. Until recently, most research has been limited to a relatively narrow number of monomers and chemistries. A fundamental challenge in developing clinically relevant polymeric biomaterials is to independently control their chem…
Large-area few-layer-MoS2 device arrays are desirable for scale-up applications in nanoelectronics. Here we present a novel approach for producing orderly arranged, pristine few-layer MoS2 flakes, which holds significant potential to be developed into a nanomanufacturing technology that can be scaled up. We pattern bu…
We report results from an efficient, robust, ab-initio method for self-consistent calculations of electronic and structural properties of Ge. Our non-relativistic calculations employed a generalized gradient approximation (GGA) potential and the linear combination of atomic orbitals (LCAO) formalism. The distinctive f…
Public attention to the food scandals raises an urgent need to develop effective and reliable methods to detect food contaminants. The current prevailing detections are primarily based upon liquid chromatography, mass spectroscopy, or colorimetric methods, which usually require sophisticated and time-consuming steps o…
Each XRD peak intensity of CaSO4･2H2O crystals changes according to their morphologies. This research clarifies the relationship between XRD peak intensity and morphologies on CaSO4･2H2O crystals synthesized by reaction crystallization with various additives. As a result, as XRD relative intensity of (021) face increa…
