Cuprous oxide (Cu2O) nanorod arrays have been prepared via a novel templated electrodeposition process and were characterized for their photocatalytic behavior in nonaqueous photoelectrochemical cells. Zinc oxide (ZnO) nanorod films serve as sacrificial templates for the in situ formation of polymer nanopore membranes…
In this study, we report a preparation and an aggregate emission behavior of an amphiphilic donor-acceptor dye, which is composed of a triphenylamine-benzothiadiazole donor-acceptor chromophore and two water-soluble hexa(ethylene glycol) chains. The dye is strongly fluorescent in nonpolar solutions such as cyclohexane…
BACKGROUND: Silver nanoparticles (AgNPs) are increasingly and extensively being applied for biomedical purposes. However, studies on the safety/toxicity profiles of AgNPs are limited. This necessitates the further studies in this direction. Here, we studied the effect of AgNP administration on rat serum metabolites an…
Samarium oxide nanoparticles (Sm <sub>2</sub> O <sub>3</sub> NP) were prepared photochemically for the first time.
A new configuration of hydrogen ion supercapacitors was reported. A positive electrode composed of pseudocapacitive MnO2, highly dispersed into active porous carbon through an impregnation method, was combined with a nitrogen-doped highly ordered mesoporous carbon with enhanced electrochemical hydrogen insertion capac…
A novel graphene structure formed by asymmetrical intercalation of FeCl3 molecules into a trilayer graphene is reported. The trilayer graphene is divided into a single layer and a bilayer graphene by the inserted FeCl3 layer. Theoretical calculation shows that such graphene bilayers with broken inversion symmetry pres…
Sertaconazole nitrate is a broad spectrum imidazole antifungal agent with antibacterial and anti-inflammatory properties. However, its lipophilic nature and very poor aqueous solubility limit its use in the clinic. The aim of this study was to develop and characterize poly(ethylene glycol)-block-poly(ε-caprolactone) (…
Graphene oxide was reacted with amino phthalonitrile (APN) <italic>via</italic> amine–epoxy, OH–CN, epoxy–CN and amine–CN reactions, resulting in a diminished <italic>T</italic> <sub>g</sub> , reduced curing temperature of APN, and also a ductile matrix without penalty in thermal stability.
The catalytic activities of CeO <sub>2</sub> , ZrO <sub>2</sub> , (PH)-CeO <sub>2</sub> /ZrO <sub>2</sub> and fluorite CeZrO <sub>4−δ</sub> oxides were reported for the oxidative dehydrogenation of ethyl benzene to styrene using O <sub>2</sub> , air and CO <sub>2</sub> as oxidants. CeZrO <sub>4−δ</sub> accounted for a…
Electromagnetic (EM) radiation, bacterial cross-infection, and electrostatic discharge hazards in working environments produce risks in workplace safety in EM industries and hospitals. Although many kinds of EM-shielding fabrics have been produced, few studies have focused on their antibacterial and other functional c…
Tunable emission has been obtained in the CKP:Eu <sup>2+</sup> , Sr <sup>2+</sup> , Mg <sup>2+</sup> phosphors by adjusting the Sr <sup>2+</sup> and Mg <sup>2+</sup> contents.
A series of electron donor-acceptor compounds based on substitution of perylene-3,4:9,10-bis(dicarboximide) (PDI) with four electron donors at the 2,5,8,11-positions were synthesized and characterized using femtosecond transient absorption spectroscopy. The distance between the PDI and the N,N-dimethylaniline or pheno…
The effect of electrospinning parameters on morphology, molecular, and supermolecular structure of polycaprolactone (PCL) fibers was analyzed, with respect to tissue engineering applications. Fibers morphology and structure are mainly determined by solution concentration and collector type. Applied voltage does not si…
Abstract Gallium selenide, an important second‐order nonlinear semiconductor, has received much scientific interest. However, the nonlinear properties in its two‐dimensional (2D) form are still unknown. A strong second harmonic generation (SHG) in bilayer and multilayer GaSe sheets is reported. This is also the first…
Combined optical and FTIR spectroscopy has been employed to investigate the undoped NaF-CaF 2 -B 2 O 3 glass together with samples containing 0.2% dopant of 3d TM ions before and after gamma irradiation. The optical spectrum of the undoped glass reveals strong UV absorption with two peaks which are related to unavoida…
Herein, the synthesis, characterization and photocatalytic application of a novel hybrid polyoxometalate, which can absorb light in the visible region, are reported. This hybrid material was synthesized by attaching a monovacant polyoxometalate, (SiW11O39), through a (3-aminopropyl)triethoxysilane linker to the anthra…
BACKGROUND: Anthropogenic nanoparticles (NPs) have found their way into many goods of everyday life. Inhalation, ingestion and skin contact are potential routes for NPs to enter the body. In particular the digestive tract with its huge absorptive surface area provides a prime gateway for NP uptake. Considering that NP…
Sterically stabilized chitin nanowhiskers (ChNWs) were prepared by surface grafting monomethoxy poly(ethylene glycol) (mPEG) via reductive amination of primary amino groups on ChNWs and terminal aldehydes on mPEG. The amount of grafted mPEG was determined to be 0.2-0.3 g/g ChNWs, by conductometric titration, from the…
A-B block copolymer micelles comprised of thermoresponsive hydrophilic PNIPAAm (poly(N-isopropylacrylamide)) coronae and hydrophobic PNP (poly(N-acryloyl-2-pyrrolidone)), PMNP (poly(N-acryloyl-5-methoxy-2-pyrrolidone)), or PBNP (poly(N-acryloyl-5-butoxy-2-pyrrolidone)) cores were examined to identify how systematic ad…
