The synthesis of novel nanoarchitectures is an important way to combine several properties into the same nanometric object. Magnetic, catalytic, optical, and electrical properties can be embedded and used for heating, moving, or monitoring the nanocomposite. Following this approach, smart materials exhibiting remarkab…
Two Mannich bases namely, N -[(4-methoxyphenyl)(morpholin-4-yl)methyl]acetamide (MMPA) and N -[morpholin-4-yl(phenyl)methyl]acetamide (MPA) were synthesized and their influence on the inhibition of corrosion of mild steel in 1.0 M H 2 SO 4 was investigated by weight loss, potentiodynamic polarization, electrochemical…
We present the preparation of ultrafine (R(h), 50 -150 nm) nanogels through tenside-free condensation of reactive prepolymers with β-cyclodextrin (β-CD) in water. These nanogels possess a maximum content of 60 wt % functional β-CD that can form inclusion complexes as demonstrated by dye sorption with phenolphthalein.…
Design and discovery of novel antifungal compounds is the need of time, more than ever before due to the unavailability of effective antifungal therapy to treat resistant fungal infections. Due to morphological and functional similarities of fungi both with plant cell and human cell, the search for effective targets l…
Nanocomposite material that consists of DBSA (dodecylbenzensulfonic acid) doped polyaniline (PANI) was prepared by solvent free mechanochemical intercalation method. Organic aniline monomer was first intercalated into the interlayer regions of Na-MMT (sodium montmorillonite) clay hosts and followed by one-step oxidati…
A brand-new type of multifunctional nanocomposites with high DC conductivity and enhanced mechanical strength was fabricated. Ionic liquid functionalized Carbon Nanotubes (CNTs-IL) were embedded into epoxy matrix with covalent bonding by the attached epoxy groups. The highest DC conductivity was 8.38 x 10-3 S.m-1 with…
The production of SWCNT has increased tremendously in the last decade, due to high expectations of their benefits. Despite all precautions SWCNT may come into contact with organisms and may be taken up by them. The aim of the present study was to assess and elucidate the effects of SWCNT bundles (purified SWCNT) and S…
This study investigated the apparent genetic redundancy in the biosynthesis of polyhydroxyalkanoates (PHAs) in the Rhodospirillum rubrum genome revealed by the occurrence of three homologous PHA polymerase genes (phaC1, phaC2, and phaC3). In vitro biochemical assays established that each gene product encodes PHA polym…
The effect of solution heat treatment on pitting behavior of 2205 duplex stainless steel was investigated by EDS, potentiodynamic polarization and SECM. The contrast experiments were carried out on the original steel. The results demonstrate that for the original sample, when the potential was at the open circuit pote…
Nineteen medium-chain-length (mcl) poly(3-hydroxyalkanoate) (PHA)-degrading microorganisms were isolated from natural sources. From them, seven Gram-positive and three Gram-negative bacteria were identified. The ability of these microorganisms to hydrolyze other biodegradable plastics, such as short-chain-length (scl)…
This study describes the interaction between crystalline cellulose and the direct dye Congo red (CR) using molecular dynamics simulations. A model of a microfibril corner of cellulose Iβ, exposing one hydrophobic (1 0 0) and the two hydrophilic (1 1 0) and (1 −1 0) surfaces was built. The energetic and geometric featu…
Boron oxide with a content of 99.93 wt.% from the dehydration of boric acid was synthesized. Conversion of boric acid to boron oxide was completed within 3 days at low temperature range ( T < 130 °C) and approximately 30 min at high temperature range ( T > 130 °C) for the isothermal dehydration reaction in the tempera…
The interlayer coupling of twisted bilayer graphene could markedly affect its electronic band structure. A current challenge required to overcome in experiment is how to precisely control the coupling and therefore tune the electronic properties of the bilayer graphene. Here, we describe a facile method to modulate th…
Electron-beam dispersion of pressed fullerite C60 targets in vacuum leads to the deposition of thin films containing polymeric forms of C60. The aim of the present report is to analyze physical-chemical processes in the fullerite target during its electron-beam dispersion through the analysis of the kinetics of the ra…
An investigation of laser stimulated thermal conductivity in chiral CNT is presented. The thermal conductivity of a chiral CNT is calculated using a tractable analytical approach. This is done by solving the Boltzmann transport equation with energy dispersion relation obtained in the tight binding approximation. The e…
Chitosan is an amino polysaccharide prepared by processing shrimp waste (shell) which involves partial deacetylation of chitin. Chitosan, a versatile natural polysaccharide, the second most abundant natural polymer. Many biochemists have found that chitosan as biocompatible, biodegradable and non toxic which made wide…
The benzylation of benzene by benzyl chloride over a series of Thallium-containing mesoporous silicas with different Tl contents has been investigated. These materials (Tl-HMS-n) have been characterized by chemical analysis, N 2 adsorption/desorption isotherm and X-ray diffraction (XRD). The mesoporous Thallium-contai…
The effect of change in solvent type on the processes involved in film formation of a 2K polyurethane are investigated using dynamic mechanical thermal analysis [DMTA] and dielectric relaxation [DR] measurements. The film formation and cure reactions for a polyol reacting with an isocyanate for solutions in ethyl acet…
Recently, rutile nanotwins were synthesized using high temperature organic solvent methods, yielding two kinds of common high-quality rutile twinned nanocrystals, (101) and (301) twins, accompanied by minor rutile nanorods (Lu et al 2012 CrystEngComm 14 3120-4). In this report, the atomic structures of the rutile and…
Abstract It is believed that the dehydrogenation of LiNH 2 BH 3 (LAB) proceeds through a combination of the decomposition of the LiBH 2 NH 3 (LBA) and LAB isomers. The dehydrogenation of LBA, an isomer of LAB, is discussed in this article. It is demonstrated that the loss of H 2 from LBA takes place in a two‐step reac…
