Many drug molecules exert their biological action on intracellular molecular targets present on or inside various cellular organelles. Consequently, it has become more evident that the efficiency and efficacy of drug action is dependent largely on how well an unaided drug molecule is able to reach its intracellular ta…
Organometallic dithienylethenes with the redox-active M(eta(5)-C(5)H(5))L(2)-type attachments (M = Fe, Ru; L = CO, PR(3)) exhibit bimodally stimuli-responsive, photo- and pseudo-electrochromic behavior with the remarkable switching factors [K(C)(closed)/K(C)(open)] up to 5.4 x 10(3).
A general precipitation strategy has been developed for the large-scale synthesis of molybdate nanostructures, and a series of molybdate nanostructures such as Fe(2)(MoO(4))(3) nanoparticles, ZnMoO(4) nanoplates, MnMoO(4) nanorods and CoMoO(4) nanowires have been successfully prepared.
Carbon nanotubes (CNTs) are considered for use in numerous technological applications, including as biocompatible modules for the delivery of bioactives. However, there are unique properties of CNTs that limit their use as vehicles for various purposes. This review highlights the various challenges to a pharmaceutical…
A novel ligand, H(12)L, based on a trimethylbenzene core bearing three methylenediethylenetriamine-N,N,N'',N''-tetraacetate moieties (-CH(2)DTTA(4-)) for Gd(3+) chelation has been synthesized, and its trinuclear Gd(3+) complex [Gd(3)L(H(2)O)(6)](3-) investigated with respect to MRI contrast agent applications. A multi…
To improve the delayed fracture strength of ultra high-strength low alloy TRIP-aided steels with bainitic ferrite matrix (TBF steels), the effects of aluminum content on hydrogen absorption behavior and delayed fracture properties of 0.2%C–0.2–1.5%Si–1.5%Mn TBF steel were investigated. When aluminum was added to the T…
Luminescent pentanuclear tetra-decker Ln(III) complexes [Eu5L4(OH)2(NO3)4(H2O)2].NO3.3H2O , [Nd5L4(OH)2(NO3)5MeOH].3MeOH.2H2O and [Eu5L4(CF3SO3)4(MeO)2(H2O)4].CF3SO3.H2O are formed from Ln(NO3)3.6H2O (Ln = Eu (1), Nd (2)) and Eu(CF3SO3)3, respectively (H2L = N,N'-bis(5-bromo-3-methoxysalicylidene)phenylene-1,2-diamine…
Fluoride abstraction from a BODIPY dye gives a well defined borenium ion which can be converted to a borenium hydride via treatment with DIBAL-H.
A facile one-pot approach gave isolated silver nanoparticles anchored on a mesostructured silica matrix in a self-assembled way; these gave 100% CO conversion in CO oxidation at room temperature, which is higher than or comparable to the conversion obtained using noble metal catalysts.
The mechanisms of physical and chemical interactions of low temperature plasmas with surfaces can be fruitfully explored using molecular dynamics (MD) simulations. MD simulations follow the detailed motion of sets of interacting atoms through integration of atomic equations of motion, using inter-atomic potentials tha…
A microporous organic framework polymer (OFP) based on a polyimide framework exhibits a high surface area (1159 m2 g(-1)) and shows a reversible H2 storage capacity of 3.94 wt% at 10 bar and 77 K, the highest yet reported for an organic polymer.
We present here a simple and effective strategy, called the vacuum nano-casting route (VNR), for fabricating hollow mesoporous spheres with magnetic cores. The loading amount of magnetic cores and saturation magnetization value can be easily tuned by changing the concentration of iron nitrate solution used in the synt…
Supermolecules composed of pre-organized mesogenic units have attracted much attention because they can form secondary and tertiary structures with unique physical properties. This Feature Article reviews recent progress in thermotropic supermolecular liquid-crystalline materials with a hierarchical structure. We take…
In this paper, a method of cultivation and characteristics of obtained bacterial cellulose is presented. It was stated that the greatest increase in the weight of bacterial cellulose takes place after 7 - 8 days of breeding Acetobacter xylinum at a temperature of 30 °C, using a Herstin-Schramm nutrient medium. The hig…
The use of a viral template has allowed the synthesis of monodisperse Prussian blue nanoparticles with a diameter of 18 +/- 1.7 nm and their organization into hexagonal patterns on mica and hydrophilic carbon surfaces.
Layered rare-earth hydroxide crystallites self-assembled at the hexane/water interface were transferred to various substrates to form a monolayer film, which exhibited photoluminescence properties and ion-exchange ability.
A tiny amount of Pt was deposited in a quasi-two-dimensional form onto the nanoporous gold (NPG) substrate through a simple immersion-electrodeposition (IE) method, forming nanostructured bimetallic Pt-Au catalysts. Such Pt-Au nanostructures have much higher structural stability than the bare NPG; moreover, they exhib…
Extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES) techniques at both Fe and Mn K-edges were used to investigate the formation of MnFe(2)O(4) nanoparticles embedded in a silica aerogel matrix as a function of calcination temperature (at 450, 750 and 900 degrees C). Up to…
In this research the adhesion and the resulting interfacial shear strength (IFFS) between the natural fibres flax, hemp and cotton and the polymer matrices polypropylene with coupling agent (MAPP) and polylactide acid (PLA) was surveyed with the single fibre fragmentation test (SFFT). The adhesion between MAPP and the…
We consider a model of nonisothermal phase transitions takingplace in a bounded spatial region. The order parameter $\psi$ is governed byan Allen-Cahn type equation which is coupled with the equation for thetemperature $\theta$. The former is subject to a dynamic boundary conditionrecently proposed by some physicists…
