Cellulose nanocrystals (CNCs) are a nano-scaled particulae material that has been shown to improve strength in cementitious pastes. One advantage of CNCs compared to other nano-materials is that CNCs are renewable and sustainable. The objective of this investigation is to investigate the influence of additional alkali…
Strong anion exchange resins with QN+OH-, have the potential to be developed and employed as heterogeneous catalyst for transesterification, as they are chemically stable to leaching of the functional group. Nine different SIERs (SIER1-9) with QN+OH-were prepared by suspension polymerization of vinylbenzyl chloridediv…
Salmon sperm DNA was used as a blocking agent to reduce background fluorescence signals from gelatin-coated cell culture dishes.
Different from traditional forming process, sheet soft punch process uses only a rigid die and the other tool set is a flexible medium, such as natural or synthetic rubbers. Soft punch stamping process for flow channel in stainless steel bipolar plates of the proton exchange membrane fuel cell (PEMFC) is an economic a…
A rigid polymer network of poly(p-phenylene benzobisoxazole) (PBO) has excellent mechanical properties and thermal stability. Many nano voids exist within the network. However, a PBO network cannot be formed into films or fibers. Generally, PBO networks are prepared by one-step polycondensation in polyphosphoric acid.…
Using rare earth oxides, aluminum nitrate and gelatin as raw materials, YAG:Eu 3+ based luminescent materials were successfully synthesized by gel-network coprecipitation method. The formation and luminescent properties of YAG: Eu 3+ was investigated by means of fluoresce spectra. For YAG:Eu 3+ , the differences for t…
Carbon is an element with a unique ability to bond with itself principally via sp 3 (diamond-like) and sp 2 (graphitelike) hybridization. This versatility results in a rich diversity of structural forms of solid carbons. Most of the
In this study, reactive dyes having different chromophore and reactive groups were used to dye polyamide fabric such as C.I. Reactive Blue 4 (Basilen Blue MR–BASF–chromophore group of anthraquinone, a reactive dye in the structure of dichlorotriazinel), C.I. Reactive Blue 15 (Cibacron Turquoise GF–CGY–chromophore grou…
Magnesium ferrite-bentonite clay composite was prepared by sol-gel combustion method employing citric acid as complexing agent and fuel. The effect of clay on the structural properties was studied with X-ray diffraction (XRD), Fourier transform infrared (FT-IR) Spectroscopy, Scanning electron microscopy (SEM), SEM- En…
Amphiphilic block copolymers (BCPs) and dendrimers are known to self-assemble in aqueous solution to form a number of aggregate morphologies. These different architectures are largely a function of the hydrophilic volume or weight fractions of the different components of the polymer system. One possible morphology is…
Fluorescent color centers in diamond nanocrystals have recently become the focus of researchers because of their potential applications in quantum information processing, nano-sensing, biomarking, and bioimaging. One of the biggest challenges in working with nanodiamonds is how to position them precisely and efficient…

In recent years, the possible synthesis of multimetallic nanostructures moulded by combining the individual noble metals attract a considerable attention in place of bare noble metals due to their improved optical response and cost effectiveness. In this study, the plasmonic response of Au composition dependent Au-Ag-…
We report a numerical study on the impacts of variations in the geometry, boundary conditions, and the coefficient of thermal expansion of the materials on the maximum shearing stress in thermoelectric power generator module (TEM) for high temperature applications. The maximum shearing stress in the TEM is evaluated f…
Maleic anhydride is an important chemical intermediate mainly produced by the selective oxidation of n-butane, an industrial process catalyzed by vanadyl pyrophosphate-based materials, (VO)2P2O7. The first topic was investigated in collaboration with a company specialized in the production of organic anhydrides (Polyn…
The UV-excited photoluminescence was measured for single CdSe nanocrystals and an average carrier multiplication efficiency of ~13.1% was obtained when the excitation photon energy was set at ~2.46 times of the nanocrystal energy gap.
Owing to their unique antimicrobial properties, silver nanoparticles (AgNP) are among the most widely used engineered nanoparticles in a variety of consumer products and medical applications. Their resulting release into the aquatic environment raises concern about potential adverse effects in aquatic organisms. This…
FePt nanoclusters have been implanted onto polyimide films and subjected to thermal annealing in order to obtain a special magnetic phase (L10) dispersed within the polymer. SQUID measurements quantified the magnetic features of the as‐prepared and annealed hybrid films. As‐implanted FePt nanoparticles in polyimide fi…
In this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. The electrochemical properties of the produced electrode are studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques in 3M NaCl, NaOH, and KOH e…
This paper investigated the effect of heat treatment operations on the fatigue resistance of low carbon steel. Specimens after preparation for fatigue testing were subjected to annealing, normalizing and quenching heat treatment. Results show that the annealed specimen had the largest number of cycles to failure, indi…
