Abstract Porous MnCeO x solid solutions nanorods (PN‐MnCeO x ) with different pore sizes were prepared using different carbon chain lengths ionic liquids (C 10 mimCl, C 12 mimCl and C 14 mimCl). Series of novel catalysts with nano‐Au supported on the PN‐MnCeOx, were synthesized and applied to oxidative esterification…
In the present research work, the effect of varying concentration of nanoclay and un-treated/treated polyethylene terephthalate fibers (PET fibers) on tensile strength of nanocomposites was investigated. Response surface methodology (RSM) using Minitab software was used in this investigation. A total 18 experiments wi…
For the fabrication of vertical power electronic components, the use of a freestanding highly boron‐doped single crystal diamond substrate is mandatory, on top of which a thin low‐doped active layer is overgrown. The crystalline quality of this substrate is of prime importance as the high doping level required is also…
Abstract A continuum model for yttria-stabilized zirconia (YSZ) in the framework of non-equilibrium thermodynamics is developed. Particular attention is given to (i) modeling of the YSZ-metal-gas triple phase boundary, (ii) incorporation of the lattice structure and immobile oxide ions within the free energy model and…
In this letter, a test platform capable of generating superimposed voltage with controllable phase is presented. Surface partial discharge(PD) of epoxy insulation was measured and analyzed in SF6. The applied voltage is AC and switching impulse superimposed voltage. Results show that only PD of the negative cycles of…
Three-dimensional porous scaffolds are essential in tissue engineering applications. One of the most conventional methods to form porosity in scaffolds is freeze-drying, which is not energy efficient and cost effective. Therefore in this work, it was experimentally investigated whether gelatin, with its unique mechani…
The Yb3+-Er3+ and Yb3+-Ho3+ co-doped Y6WO12 (YWO) luminescent materials were synthesized successfully using the solid-state reaction method, and their phase purity, upconversion (UC) spectra, and optical temperature sensing properties were studied. Upon 980 nm excitation, the dominant emission peak around 660&#…
We present a first-principles theoretical approach to calculate temperature dependent phonon dispersions in bcc Fe, which captures finite temperature spin-lattice coupling by treating thermal disorder in both the spin and lattice systems simultaneously. With increasing temperature, thermal atomic displacements are fou…
Polyhydroxybutyrate (PHB) is biodegradable and renewable and thus considered as a promising alternative to petroleum-based plastics. However, PHB production is costly due to expensive carbon sources for culturing PHB-accumulating microorganisms under sterile conditions. We discovered a hyper PHB-accumulating denitrify…
Abstract Interface‐induced modifications of the electronic, magnetic, and lattice degrees of freedom drive an array of novel physical properties in oxide heterostructures. Here, large changes in metal–oxygen band hybridization, as measured in the oxygen ligand hole density, are induced as a result of interfacing two i…
Improving energy dissipation in lightweight polymer nanocomposites to achieve environmentally friendly and mechanically stable structures has reached a limit because of the low-density electrostatic interactions that can be harnessed through the stick-slip mechanism between carbonaceous nanofillers and polymeric chain…
We study the photoluminescence properties of the red-emitting phosphor Ca 9 Eu(VO 4 ) 7 and establish a strong red emission centered at 613 nm under excitation at 395 nm (near ultra violet light, near-UV light) due to the intra-configurational 5 D 0 → 7 F 2 transition within the 4f 6 configuration of the Eu 3+ ions. T…
A new fluorescent probe (BDP-Fe2+) was developed for targeting dopamine, with a boron–dipyrromethenyl (BDP) group as the fluorophore and a Fe2+ complex as the ligand exchange site. The free form of BDP-Fe2+ in solution displayed weak fluorescence emission, while it showed strong fluorescence emission after interaction…
Abstract Double-walled hierarchical porous silica nanotubes (NTs) loaded Au nanoparticles (Au NPs) in the interlayer (SiO 2 @Au@SiO 2 NTs) are synthesized by using tetraethoxysilane as silica source and hollow polydivinylbenzene (PDVB) nanowires as the sacrificial templates. The mesopores on the walls and the hollow s…
Corrosion of ferrous metals and its effects on degradation of mechanical properties and the remaining service life of metal structures have been a serious challenge to research community globally. This paper aims to investigate the problem thoroughly with experimental, numerical and analytical means. It presents resul…
) polypropylene/poly(acrylonitrile-butadiene-styrene) (PP/ABS) nanocomposites were fabricated. The contents of O-Sep were correlated with the morphological, mechanical, and rheological behavior of PP/ABS/O-Sep blends. Scanning electron microscopy (SEM) was applied to study the morphology and thermogravimetric analysis…
Monoclonal antibodies can effectively target to tumors in patients, as validated by antibody-drug conjugates (ADCs). The clinically used ADCs, nevertheless, are restricted to toxins only and suffer from low drug content, excessive use of antibody, and high cost. Here, we report on trastuzumab-decorated disulfide-cross…
In this study, photochromic fabrics were prepared by incorporating the spirooxazine derivative of 5-chloro-1,3-dyhydro-1,3,3-trimethylspiro[2H-indole-2,3′-[3H]-naphth [2,1-b] [1,4] oxazine on the polyethylene terephthalate (PET) fabric through a sol-gel coating process. The treated fabrics showed good photochromic res…
