Stable non-crystalline toluene films of micrometer and nanometer thicknesses were grown by vapor deposition at distinct rates and probed by fast scanning calorimetry. Fast scanning calorimetry is shown to be extremely sensitive to the structure of the vapor-deposited phase and was used to characterize simultaneously i…
The C–Cl bond activation by Au/Pd bimetallic alloy nanocatalysts has been investigated with regard to the oxidative addition of chlorobenzene (PhCl). Fifteen stable structures of the Au 10 Pd 10 nanocluster (NC) obtained by a genetic algorithm were examined by DFT calculations using the M06-L, TPSS, and B3LYP function…
In nature, a few living organisms such as diatoms, magnetotactic bacteria, and eggs have developed specific mineral structures, which can provide extensive protection or unique functions. However, most organisms do not have such structured materials due to their lack of biomineralization ability. The artificial introd…
Molecular and dissociative adsorption behavior of H 2 O along with the accompanying H 2 formation mechanism on the UO 2 (111) and (110) surfaces have been investigated by using DFT+U calculations. According to our calculations, the higher stability of the (111) surface leads to higher oxygen vacancy formation energy c…
The origin of high rates of hydrogen evolution (HE) on dissolving Mg, the so-called negative difference effect, remains of practical interest. Recent studies have suggested that the ability of Mg to support the cathodic reaction is enhanced during dissolution and that enrichment of noble impurity elements at the disso…
There are a multitude of polymeric materials currently utilized to prepare a variety of blood-contacting implantable medical devices. These devices include tissue grafts, coronary artery and vascular stents, and orthopedic implants. The thrombogenic nature of such materials can cause serious complications in patients,…
Natural fiber-reinforced composites have advantages such as light weight, unique mechanical properties, good sound absorption, and heat isolation performances. However, low interlaminar properties of natural fiber-reinforced composite laminates caused by the poor interfacial properties between natural fibers and polym…
In this study, for the first time, polymeric precursors have been used in the preparation of yolk-shell powders using a large-scale spray drying process. An esterification reaction between the carboxyl group of citric acid and the hydroxyl group of ethylene glycol inside the droplet produced organic polymers during th…
Biobased materials are rapidly emerging as alternatives to petroleum-based materials because of rising environmental awareness and augmented consumption of nondegradable polymers. In the present work, the surface characteristics of biorenewable soy flour (SOY) were tailored via free radical-induced graft copolymerizat…
A solvothermal method was used to prepare zinc ferrite spinel oxide (ZnFe₂O₄) using ethylene glycol and 1,4 butanediol as solvent diols, and the influence of diols on the physical properties of ZnFe₂O₄ particles was investigated. The produced particles were characterized by X-ray powder diffraction (XRD), atomic force…
Boiling heat transfer (BHT) is a particularly efficient heat transport method because of the latent heat associated with the process. However, the efficiency of BHT decreases significantly with increasing wall temperature when the critical heat flux (CHF) is reached. Graphene has received much recent research attentio…
Simple methods to self-assemble coatings and films encompassing nanoparticles are highly desirable in many practical scenarios, yet scarcely any examples of simple, robust approaches to coat macroscopic droplets with continuous, thick (multilayer), reflective and stable liquid nanoparticle films exist. Here, we introd…
A magnetothermally-responsive nanocarrier was developed for efficient thermo-chemotherapy by combining efficient magnetic hyperthermia (MH) and magnetothermally-facilitated drug release. The effective magnetothermal-response contributed to high enhancement of tumor cell killing by an operating mechanism involving MH-f…
Increased protons in TNTs exchange with alkaline metal cations, protecting CeO <sub>2</sub> and achieving enhanced alkaline poisoning resistance.
Transmission electron microscopy (TEM) is used to study growth of MoS 2 nanocrystals in situ . The nanocrystals are formed from a submonolayer molybdenum oxide dispersed on an oxide support by sulfidation in an H 2 S/H 2 atmosphere. From series of time-resolved TEM images, it is revealed that single-layer MoS 2 nanocr…
A systematic study of the ignition behavior of furan and the substituted furans 2-methyl furan (2-MF) and 2,5-dimethyl furan (DMF) is presented. Ignition delay times are measured over a temperature range from 977 to 1570 K and pressures up to 12 atm for lean, stoichiometric, and rich mixtures of fuel, oxygen, and argo…
Under technologically relevant oxygen-rich conditions, the reaction mechanism of CO oxidation over transition metals can be complicated by the formation of oxides. Questions of whether the active surface for CO oxidation is a pristine metal, a surface oxide, or a bulk oxide is still under active debate. In this study,…
The effects of chlorite bleaching on the properties of cellulose derived from oil palm empty fruit bunch (OPEFB) fiber were investigated in this work. Cellulose was extracted from oil palm empty fruit bunch fiber via chlorite bleaching, alkali treatment, and acid hydrolysis. Cellulose was extracted by varying the blea…
Using molecular dynamics, the thermophysical properties of the (U x ,Th 1− x )O 2 system have been investigated between 300 and 3600 K. The thermal dependence of lattice parameter, linear thermal expansion coefficient, enthalpy and specific heat at constant pressure is explained in terms of defect formation and diffus…
Evaluation of cytotoxicity, photoluminescence, bio-imaging, and sonosensitizing properties of silicon nanoparticles (SiNPs) prepared by ultrasound grinding of porous silicon nanowires (SiNWs) have been investigated. SiNWs were formed by metal (silver)-assisted wet chemical etching of heavily boron-doped (100)-oriented…
