Abstract We synthesized a new room temperature ionic liquid, [2PA-Hmim][Pf2N], and characterized the photochromic behavior by absorption spectroscopy. [2PA-Hmim][Pf2N] was found to be a photochromic liquid where solvent itself undergoes photochromic reaction.
Abstract We prepared photomobile polymer fibers with anthracene side groups and explored their photomechanical properties. Upon irradiation with UV light, the fiber bent toward an actinic light source. The degree of bending and photoreaction were strongly affected by temperature. The fiber can dose the deformation wit…
The metal-dependent deacetylase UDP-3-O-[(R)-3-hydroxymyristoyl]-N-acetylglucosamine deacetylase (LpxC) catalyzes the first committed step in lipid A biosynthesis, the hydrolysis of UDP-3-O-myristoyl-N-acetylglucosamine to form UDP-3-O-myristoylglucosamine and acetate. Consequently, LpxC is a target for the developmen…
BACKGROUND: The influence of liposome composition, lamellarity, preparation method, and charge on the encapsulation efficiency, size, polydispersity, and surface charge of sumatriptan liposomes was studied. For this purpose, we studied multilamellar, unilamellar, and frozen and thawed liposomes. Positively or negative…
In the past decades, montmorillonite nanoclay has been used successfully to strongly improve properties of polymers. Similar improvements to nanoclay modified bitumen were expected, so the montmorillonite nanoclay was adopted to modify bitumen. To understand the interaction with bitumen, it was of fundamental importan…
The transport properties of a octane-dithiol (ODT) molecule coupled to Au(001) leads are analyzed using density functional theory and non-equilibrium Green functions. It is shown that a symmetric molecule can turn into a diode under influence of a local electric field created by an external charged probe. The origin o…
Two possible phases of superhard material BC3 originating from the cubic diamond structure are investigated by ab initio pseudopotential density functional method using generalized gradient approximation (GGA). We calculate their elastic constants, electronic band structure, and density of states (DOS). Full phonon fr…
Two hydrated strontium borate(SrB_2O_4·4H_2O and SrB_6O_(10)·5H_2O) were synthesized by liquid-phase precipitation method,and pure phase strontium tetraborate(SrB_4O_7) was obtained by high temperature calcination.The phase compositions,morphology and the high temperature sintering process of products were characteriz…
A series of acrylonitrile-butadiene-styrene terpolymers(ABS) were synthesized by bulk polymerization using polybutadiene rubber as toughener.The mechanical properties of the resultant materials were investigated.The results show that high—cis rubber BR9004 has the best toughening effect far superior to the rest,and th…
The oxidation behavior of reaction-bonded porous silicon carbide(RPSC) ceramics with different open porosities was studied in dry oxygen between 1200 and 1500℃.RPSC ceramics exhibited a rapid mass increase in the initial stage of oxidation and a slow mass increase in the following oxidation. This oxidation behavior of…

The microstructure characterization of Fe_2(MoO_4)_3 and Fe_2(MoO_4)_3/Si_3N_4 composite powder reduced by hydrogen were investigated,and the formation mechanism of the latter was analyzed. The results show that the microstructure of Fe_2(MoO_4)_3 powder particles reduced by hydrogen was consisted by Mo particles coat…
A novel biphasic calcium phosphate(BCP) amorphous CPP/crystallineβ-TCP was prepared by adding calcium polyphosphate(CPP) into hydroxyapatite(HA).The effects of CPP dosage (mass fraction) on the phase compositions,sintering property,and mechanical strength of the composite were investigated.Results show that CPP would…
Komposit merupakan kombinasi makroskopik dari dua material atau lebih yang berbeda, menghasilkan sifat gabungan dari komponen keduanya. Komposit Cu/Al2O3 merupakan paduan antara Cu sebagai matrik dan Al2O3 sebagai penguat. Pembuatan komposit ini dilakukan dengan proses metalurgi serbuk karena dapat dilakukan kontrol t…

A polyaniline/graphite (PAn/C graphite ) composite was successfully synthesized by an in-situ polymerization process. The composite was characterized through various techniques. Structural investigations were carried out through FTIR spectroscopy and SEM-EDX methods. The analyses of the composite clearly demonstrate t…
Conventional plastics manufactured from non-renewable fossil fuels contribute heavily to solid waste disposal. This study showed that the proper selection of enhancer added to the polysaccharide kappa-carrageenan (?C) can improve the properties of the resulting water soluble plastic film. This study is focused on the…
