The CO oxidation ability can be modulated by controlling the metal–support interaction of Pt/CeO 2 catalysts. The Pt/(800C)CeO 2 sample prepared by the thermal treatment of ceria at 800 °C before loading Pt maintained the much higher Pt dispersion than Pt/γ-Al 2 O 3 after the thermal aging at 800 °C, indicating its ex…
A decline in the world’s freshwater resources poses a major domestic and industrial challenge. Amelioration efforts that proffer possible water management and reclamation technology is therefore, of utmost priority. One of the most promising solutions to water conservation is to recycle wastewater. The use of polymeri…
Abstract A series of rod‐shaped polyoxometalates (POMs) [Bu 4 N] 7 [Mo 6 O 18 NC(CH 2 O) 3 MnMo 6 O 18 (OCH 2 ) 3 CNMo 6 O 18 ] and [Bu 4 N] 7 [ArNMo 6 O 17 NC(CH 2 O) 3 MnMo 6 O 18 (OCH 2 ) 3 CNMo 6 O 17 NAr] (Ar=2,6‐dimethylphenyl, naphthyl and 1‐methylnaphthyl) were chosen to study the effects of cation–π interacti…
By using first principles calculation dependent on the density functional theory (DFT), we have investigated the mechanical, structural properties and the Debye temperature of Fe 2 ScM (M=P and As) compounds under various pressures up to 60 GPa. The optical properties have been investigated under zero pressure. Our ca…
A powerful system for studying protein aggregation, particularly rapid self-assembly, is spider silk. Spider silks are proteinaceous and silk proteins are synthesized and stored within silk glands as liquid dope. As needed, liquid dope is near-instantaneously transformed into solid fibers or viscous adhesives. The dom…
Aiming to address the antimicrobial resistance and environmental burdens because of the widespread indulgence in biocides, a synthetic formula of biocides with controllable antibacterial activities and biodegradable characters are encouraged for the emergence of a novel spectrum of green biocides. In this respect, a p…
In this study, magnetic nanoparticles (MNPs) coated with glycine (F-Gly NPs) and conjugated with methotrexate (MTX) (F-Gly-MTX NPs) were synthesized through a coprecipitation method followed by amidation reaction between the carboxylic acid end groups on MTX and the amine groups on the MNPs surface and studied its cyt…
Melamine (M), phenol (P) and formaldehyde (F) were used as raw materials to synthesize a melamine–phenol–formaldehyde resin (MPF) which was used as shell material to prepare a self-healing microcapsule with E-51 epoxy resin as the core, via in situ polymerization. Fourier transform infrared spectroscopy, environmental…
We recently reported the photophysical properties of boron dipyridylmethene (DIPYR) dyes, a class of intensely fluorescent pyridine-based chromophores, which are structural analogues of both acenes and BODIPYs. In this work, we endeavored to explore the properties of DIPYR dimers. The synthesis and characterization of…
Significant wastage of residual liquid food, such as milk, yogurt, and honey, in food containers has attracted great attention. In this work, a bio-inspired edible superhydrophobic interface was fabricated using U.S. Food and Drug Administration-approved and edible honeycomb wax, arabic gum, and gelatin by a simple an…
Four seven-nuclearity 3d-4f heterometallic cluster {Fe 6 LnO 28 } substituted polyoxometalates (HPz) 11 K 4 Fe 6 Ln(μ 3 -O) 2 (B-α-GeW 9 O 34 ) 2 (GeW 6 O 26 )· x H 2 O ( 1-Ln, Pz = piperazine, Ln = Tb, Dy, Ho, Er for x = 27, 25, 25, 24, respectively) have been hydrothermally prepared and structurally characterized by…
Abstract Ink‐free printing based on rewritable paper is an efficient and environmental friendly way to reuse paper, protect resources, and save energy for sustainable development of human society. Among various kinds of rewritable media, light responsive rewritable paper (LRP) is one of the most popular research areas…
Defect chemistries of metal-doped CeO 2 catalysts have attracted extensive scientific interests in heterogeneous catalysis. Here, we report the structure–activity relationship of CeO 2 catalysts doped by Pr. The Pr-doped CeO 2 solid solution catalysts were prepared by a coprecipitation method and evaluated in Prins co…
Carbon dots (CDs) have attracted increasing interest in bioimaging and sensing recently. Herein, we present a simple synthetic strategy to prepare yellow-emissive CDs (λ em = 535 nm) by one-pot hydrothermal treatment of p -phenylenediamine and aspartic acid. The as-prepared CDs possess outstanding optical features, ex…
Graphene/Si Schottky junction solar cells are widely studied in relation to the harvesting of solar energy, but high efficiency is limited due to surface recombination at the interface. Moreover, surface defects, wrinkles, and impurities may arise during the wet transfer process of graphene. We propose an easy approac…
Uniform poly(lactic acid)/cellulose nanocrystal (PLA/CNC) fibrous mats composed of either random or aligned fibers reinforced with up to 20 wt % CNCs were successfully produced by two different electrospinning processes. Various concentrations of CNCs could be stably dispersed in PLA solution prior to fiber manufactur…
We present an application of Eliashberg theory of superconductivity to study a set of novel superconducting systems with a wide range of structural and chemical properties. The set includes three intercalated group-IV honeycomb layered structures, SH3 at 200 GPa (the superconductor with the highest measured critical t…
Numerous consumer products, such as cosmetics, contain nanoparticles (NPs) of titanium dioxide (TiO 2 ) or zinc oxide (ZnO); however, this raises questions concerning the safety of such additives. Most of these products do not indicate whether the product includes NPs. In this study, we characterized metal oxide NPs a…
In this work, CoFe 2 O 4 nanoparticles coated with polyethylene glycol (PEG) were successfully synthesized via a hydrothermal technique. Morphological studies of the samples confirmed the formation of polycrystalline pure-phase PEG-CoFe 2 O 4 nanoparticles with sizes of about 24 nm. Toxicity induced by CoFe 2 O 4 nano…
Human mesenchymal stem cell (hMSC) sheets hold great potential in engineering three-dimensional (3D) completely biological tissues for diverse applications. Conventional cell sheet culturing methods employing thermoresponsive surfaces are cost ineffective, and rely heavily on available facilities. In this study, a cos…
