Aiming at a general methodology for binary co-assembly of complexes of different metals through quasiracemate crystallization, the hexadentate ligand 1 comprised of the chiral bipyrrolidine core and two bipyridine peripheral arms is introduced. Ligand 1 was found to bind in a fully diastereoselective and uniform mode…
Alcohol partitioning by narrow single-walled carbon nanotubes (SWCNTs) holds the promise for the development of novel nanodevices for diverse applications. Consequently, in this work, the partition of small alcohols by narrow tubes was kinetically and structurally quantified via molecular dynamics simulations. Alcohol…
Scaffolds used in tissue engineering applications should have high biocompatibility with minimum allergic, toxic, apoptotic, or necrotic effects on the growing cells and newly forming tissue and, if possible, have antimicrobial property to prevent infection at the host site. In this study, novel micro-fibrous chitosan…
A series of N-doped TiO2 photocatalysts were synthesized by simple hydrolysis method using titanium isopropoxide and pyridine precusors. XRD studies of all the catalysts showed a single anatase phase and TEM results confirmed that the particles obtained by this procedure are of nano size and in the range of 3–5 nm. UV…
Abstract A newly synthesized compound, [H3O][Co2(dat)(sdba)2]⋅H2sdba⋅5 H2O (I, dat=3,5‐diamino‐1,2,4‐triazole; H2sdba=4,4′‐sulfonyldibenzoic acid), has Co2 “paddlewheel” units connected by sdba ligands to form one‐dimensional chains, which are connected by dat to form an anionic three‐dimensional structure with cds to…
The possibility of preparing molding-bioengineered materials, such as woodchip boards (WCB), from sawdust using technical lignosulfonate (LGS), a wood waste product, and a culture liquid (CL) of levan microbial polysaccharide producer by Azotobacter vinelandii D-08 is explored in this article. The parameters of the de…
BACKGROUND: Mechanical analysis of human hair may provide the dermatologists with several markers of considerable diagnostic importance. The aim of this study was to analyse the physical and mechanical properties of Tunisian women's hair. METHODS: Surface characteristics were determined with scanning electron microsco…
The isothermal oxidation of a new Fe–Ni–Cr-based alloy has been investigated in pure steam at 750 °C for exposure time up to 500 h using secondary electron microscope (SEM)/ X-ray energy-dispersive spectroscopy (EDS) and X-ray diffraction (XRD). Results showed that the alloy was oxidized approximately following a para…
Catecholamine synthesis and transmission in the brain are influenced by the availability of Tyr in the body. In this study, we compared the effects of oral administration of Tyr-containing dipeptides Ile-Tyr, Ser-Tyr, and Tyr-Pro with Tyr alone on catecholamine metabolism in the mouse brainstem. Among these dipeptides…
The solubilities of trans- cinnamic acid ( t -CA) in methanol, ethanol, propanol, n -butanol, isopropyl alcohol, and isobutyl alcohol were measured by a synthetic method at temperatures ranging from (283.15 to 333.15) K. The modified Apelblat equation, the λh equation, and activity coefficient models (nonrandom two-li…
In this work, a previously developed (White et al 2015 J. Mater. Chem . A 3 762) rapid synthesis approach is used to fabricate native and cross-linked aerogel monoliths with customized geometries. This technique does not require solvent exchange, therefore fabrication times do not depend on part size. To prove this, p…
Polysiloxane microspheres containing a large number of silanol groups were obtained by an emulsion process of modified polyhydromethylsiloxane. N‐substituted imidazole groups were grafted on these microspheres by the silylation of their silanol groups with N‐[γ‐(dimethylchlorosilyl)propyl]imidazole hydrochloride. The…
Methanol, unlike water, is miscible with 1-butanol in all proportions however not much work is available on binary mixtures of the two alcohols. Investigation of 1-butanol–methanol binary system ( the mixture ) can be interesting also for its general and industrial applications. In the present study densities over the…
The major aim of this study was to design chitosan/alginate nanoparticles as swelling controlled drug release system for anticancer drugs. The prepared nanoparticles were characterized by FTIR and transmission electron microscopy analysis and their biocompatibility and in vitro cytotoxicity were evaluated. The nanopar…
This contribution describes the structure of cationic sites in alkali metal-grafted high-silica USY zeolites, a novel class of zeolite base catalysts, through the combination of computational studies and experimental evidence. Based on density functional theory calculations, we investigate the geometry various defects…
Well-defined AbBA triblock bottlebrush with poly(N,N-dimethyl acrylamide) (PAm) as A block and polyacrylate, densely grafted with poly(tert-butyl acrylate)-block-polystyrene (PBA-b-PS), as brush bB block is prepared by controlled radical polymerization and click chemistry. The triblock copolymer with a composition of…
Tetraphenylhexaazaanthracene (TPHA), a fluorescent zwitterionic biscyanine with a closed-shell singlet ground state, on treatment with manganese dioxide or phenyliodine bis(trifluoroacetate) (PIFA), undergoes oxidative dimerization to give a near-zero dipole scissor 5,5'-dimer DI-TPHA. Both acene components of the new…
Locating corona discharges is essential for the safe operation and the reliability of smart grid. This paper proposed a novel method for corona discharge location based on tunneling magnetoresistive (TMR) sensors. A dual-axial TMR sensor device was designed to measure the vector magnetic field. The sensor's responses…
Identifying a suitable polymeric biomaterial for myocardial patch repair following myocardial infarction, cerebral infarction, and cartilage injury is essential. This study aimed to investigate the effect of the novel polymer material, poly3-hydroxybutyrate-co-3-hydroxyhexanoate, on the adhesion, proliferation, and di…
Highly stable nanoscale gas states at solid/liquid interfaces, referred to as nanobubbles, have been widely studied for over a decade. In this study, nanobubbles generated on a hydrophobic Teflon amorphous fluoroplastic thin film in the presence and absence of hydrophilic carbon domains are investigated by peak force…
