This study presents the synthesis of microporous polystyrene particles and the potential use of these materials in CO(2) capture for biogas purification. Highly cross-linked polystyrene particles are synthesized by the emulsion copolymerization of styrene (St) and divinylbenzene (DVB) in water. The cross-link density…
In this letter, the design of a light-weight magnetic radar absorber (RA) having broadband bandwidth in frequency range of 1-18GHz is demonstrated. A 5mm-thick magnetic RA with weak wave absorbing performance is obtained on the basis of polyurethane foam filled with flake ferrous microwave absorbent. The use of freque…
Tri-n-butyl phosphate (TBP) is an important extractant for separating hexavalent uranium and tetravalent plutonium from used nuclear fuel by solvent extraction. In such solvent extractions using TBP, the organic phase occasionally separates into two organic phases, namely, light and heavy organic phases. The latter on…
Within the semiclassical approach, we calculate contributions of the Berry phase and of the Zeeman coupling of an electron moment with the magnetic field to the phase of the Shubnikov--de Haas oscillations for the surface electrons in the Bi${}_{2}$$X$${}_{3}$ family of three-dimensional topological insulators ($X$ st…
Abstract A new boron–dipyrromethene (BODIPY) derivative (FS1) containing two triazole units exhibits an enhanced fluorescence in the presence of Hg2+ ions and a high selectivity for Hg2+ ions over competing metal ions in methanol: Ag+, Ca2+, Cd2+, Co2+, Cu2+, Fe2+, Fe3+, K+, Mg2+, Mn2+, Ni2+, Pb2+, and Zn2+ produced o…
Amelioration of sodic soils is commonly achieved by applying gypsum, which increases soil hydraulic conductivity by altering soil chemistry. The magnitude of hydraulic conductivity increases expected in response to gypsum applications depends on soil properties including clay content, clay mineralogy, and bulk density…
The structurally characterized lower rim 1,3-di{4-antipyrine}amide conjugate of calix[4]arene (L) exhibits high selectivity toward Hg(2+) among other biologically important metal ions, viz., Na(+), K(+), Ca(2+), Mg(2+), Mn(2+), Fe(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Cd(2+), Hg(2+), Pb(2+), and Ag(+) as studied by flu…
Determination and control of the parameters influencing three-phase contact formation and wetting film stability under dynamic conditions is important for both industrial applications and fundamental studies. Hydrophobicity profoundly affects not only the critical thickness of rupture but also the subsequent rate of t…
Preorganizing a ligand in the conformation it adopts upon binding to a protein has long been considered to be an effective way to improve affinity by making the binding entropy more favorable. However, recent thermodynamic studies of a series of complexes of the Grb2 SH2 domain with peptide analogues having constraine…
In order to develop the potential application of industrial alkali lignin, its acrylonitrile-butadiene-styrene (ABS) composites were fabricated via melt blending in the absence/presence of a compatibilizer. The lignin can uniformly disperse in the ABS matrix with number-average dispersed-phase domains of sub-micron sc…
Single-particle rotational tracking is of great importance to monitor orientation changes of biomolecules and to understand their functions and mechanisms in biological systems. Differential interference contrast (DIC) microscopy has been found to be an excellent tool to measure polarization anisotropy for tracking ro…
Surface-tethered biomolecules play key roles in many biological processes and biotechnologies. However, while the physical consequences of such surface attachment have seen significant theoretical study, to date this issue has seen relatively little experimental investigation. In response we present here a quantitativ…
An aqueous two-phase system (ATPS) composed of thermo-separating polymer and salt was deployed in this study for the recovery of Bacillus cereus cyclodextrin glycosyltransferase (CGTase) and recycling of phase components simultaneously. CGTase was recovered using ATPS over two successive extractions and the recycled p…
Ethanolic extract of Annona muricata L., Annonaceae, leaf (AML) was used to investigate its antinociceptive and anti-ulcerogenic activities and the involvement of the mechanism of ethanolic leaves extract of AML in various animal models. Antinociceptive activity of AML extract was done using acetic acid-induced abdomi…
Finding a Si-based material with strong optical activity at the band-edge remains a challenge despite decades of research. The interest lies in combining optical and electronic functions on the same wafer, while retaining the extraordinary know-how developed for Si. However, Si is an indirect-gap material. The conserv…
The reactions of N, N′ -di(3-pyridyl)adipoamide ( L ) with the corresponding silver(I) salts afforded the complexes {[Ag( L )](PF 6 )·2CH 3 CN} ∞, 1, {[Ag( L )](BF 4 )·CH 3 CN} ∞, 2, {[Ag( L )](NO 3 )·CH 3 CN} ∞, 3, {[Ag( L )](PF 6 )·4DMF} ∞, 4, {[Ag( L )](BF 4 )·4DMF} ∞, 5, {[Ag( L )](CF 3 SO 3 )·DMF} ∞, 6, {[Ag( L )…
We experimentally determined the three-dimensional temperature distribution and modification mechanism in a soda-lime-silicate glass under irradiation of ultrafast laser pulses at high repetition rates by analyzing the relationship between the morphology of the modification and ambient temperature. In contrast to prev…
The polymer nanocomposites are composed of different nanometer units and organic polymer materials. In this review article, we have summarized different novel nanometer units which can be divided into inorganic materials and organic materials. For (inorganic materials)-polymer nanocomposites, the nanometer units inclu…
Functionalization of zinc oxide (ZnO) nano-objects by silane grafting is an attractive method to provide nanostructured materials with a variety of surface properties. Active hydroxyl groups on the oxide surface are one of the causes governing the interfacial bond strength in nanohybrid particles. Here, "as-prepared"…
The capping agent plays a critical function in anisotropic crystal growth to induce polyhedral morphology of a nanocrystal. Uniform and single-crystalline α-Fe 2 O 3 polyhedral nanoparticles in the hexagonal single crystal system named truncated hexagonal bipyramid for the first time were successfully synthesized by a…
