To evaluate the content of nitrogen (N) fractions of agricultural soils in Java, Indonesia, in relation to soil type and land use, 46 surface soil samples, 23 from paddy and 23 from upland, were collected throughout Java to include various types of soils. Soil N was separated into four fractions according to form and…
A comprehensive study has been performed on a series of solution processable phenyl substituted diketopyrrolopyrroles blended with [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) in order to investigate how systematic chemical modifications such as solubilizing groups and conjugation length impact solar cell perfo…
The aim of this study was to develop and test a controlled delivery system of two adipogenic factors (insulin and dexamethasone [Dex]), to generate stable adipose tissue when mixed with disaggregated human fat. Both drugs were encapsulated in poly(lactic-co-glycolic acid), (PLGA) microspheres (MS) and mixed with human…
A new fluorescent derivative (1) containing coumarin exhibits Fe(III)-selective strong yellow-green fluorescence in ethanol. This compound could be used as an “off-on” chemosensor and allow the detection of Fe3+ by monitoring changes in absorption and fluorescence spectra. Upon addition of Fe3+, an overall emission ch…
Due to the large spin-orbital coupling in the layered $5d$-transition metal chalcogenides compound, the occurrence of superconductivity in doped Ir${}_{2\ensuremath{-}x}$Pd${}_{x}$Te${}_{2}$ offers a good chance to search for possible topological superconducting states in this system. We did comprehensive studies on t…
Nanostructured titanium nitride (TiN) films with varying porosity were prepared by the oblique angle deposition technique (OAD). The porosity of films increases as the deposition angle becomes larger. The film obtained at an incident angle of 85° exhibits the best catalytic activity and sensitivity to hydrogen peroxid…
The prospect of ethanol dry reforming process to utilize CO2for conversion to hydrogen, syngas, and carbon nanofilaments using abundantly available biofuel—ethanol, and widely available environmental pollutant CO2is very enthusiastic. A thermodynamic analysis of ethanol CO2reforming process is done using Gibbs free en…
A numerical simulation for urea decomposition into ammonia with static mixers was performed for marine selective catalytic reduction. Three types of mixer were considered to improve urea into ammonia conversion rate. The effect of each mixer such as pressure drop, particle residence time, and uniform distribution of u…
The solubility, density and refractive index of RbCl/CsCl + [C n mim]Cl ( n = 2, 4, 6, 8) + H 2 O saturated systems have been studied at T = (288.15, 298.15 and 308.15) K. The solubility data were correlated by the nonrandom two-liquid (NRTL) model and an empirical equation. Both models can qualitatively represent the…
The SAR matrix data structure organizes compound data sets according to structurally analogous matching molecular series in a format reminiscent of conventional R-group tables. An intrinsic feature of SAR matrices is that they contain many virtual compounds that represent unexplored combinations of core structures and…
Maturity and fineness are important physical properties of cotton fibers affecting qualities of fibers and yarns. A number of methods are used for measuring fiber maturity and fineness from developed fibers that are desiccated and harvested from open bolls. With the recent advent of molecular breeding and genomics, th…
Quantum chemical calculations of the structures, stabilities, and metalophilic interactions of AuX halides (X = F-At) at the CCSD(T) theoretical level with extended basis sets were performed. Natural bond orbital analysis showed that the present gold-halide metalophilic interactions mainly resulted from the overlap of…
We measure the spatially resolved microstructure and concentration in the plane of flow for a viscoelastic solution of polymer-like micelles comprised of mass fraction 6.0% (volume fraction 6.6%) solution of 2:1 molar ratio cetylpyridinium chloride/sodium salicylate in 0.5 mol/L NaCl/D 2 O through the shear banding tr…
Oscillation during electrocatalytic oxidation of formic acid at Pt electrode under galvanostatic conditions in acidic electrolyte has been simulated based on a chemical model that involves three reaction pathways: (i) the indirect pathway via CO ad formation (formic acid dehydration) and oxidation; (ii) a formate path…
Abstract Crystals of Li[N(CN)2] were synthesized from a metathesis reaction of stoichiometric amounts of aqueous solutions of Na[N(CN)2] and Li2[SO4] followed by subsequent treatment with ethanol and evaporation of the filtered‐off solution at 80 °C under normal atmospheric conditions. The single crystals of the title…
Nitrogen-doped mesoporous carbons (NMPCs) with well-developed polyhedral morphology were prepared by direct carbonization of zeolitic imidazolate framework-8 (ZIF-8) nanopolyhedrons. The fantastic structural characteristics of NMPCs such as ultrahigh BET surface area (1960 m(2) g(-1)), large pore volume (1.16 cm(3) g(…
All-atom molecular dynamics simulations were employed to provide microscopic mechanism for the salt tolerance of polyelectrolytes dispersants. The conformational variation of polyelectrolytes and interactions between COO− groups and counterions/water molecules were also studied via radius of gyration and pair correlat…
Fluorescent indicators based on β-keto-acid bidentate coordination motifs display superior metal selectivity profiles compared to current o-aminophenol-N,N,O-triacetic acid (APTRA) based chelators for the study of biological magnesium. These low denticity chelators, however, may allow for the formation of ternary comp…
Bilayer skin substitutes constitute an attractive strategy towards improved skin wound healing. Therefore, solvent casting and freeze-drying methodologies are used to produce polyhydroxybutyrate-co-hydroxyvalerate (PHBV) thin nanoporous membranes and 3D porous scaffolds that are combined in bilayer structures to recre…
At 320 K, the crystal structure of CeRuSn is commensurate with the related CeCoAl-type of structure by the doubling of the c lattice parameter. However, with lowering the temperature it becomes incommensurate with x and z position parameters at all three elemental sites being modulated as one moves along the c-axis. T…
