The structural evolution of biodegradable poly(butylene succinate- <italic>co</italic> -terephthalate) copolymer was investigated during the uniaxial stretching and following heating processes <italic>via in situ</italic> small-angle X-ray scattering.
Initial attachment of human oral keratinocytes cultured on yttria-stabilized tetragonal zirconia polycrystal (TZP) surfaces that were subjected to UV or oxygen plasma (O2-plasma) treatment was investigated. The viability of the attached cells, mRNA expression of laminin γ2 and integrin β4, distribution of laminin γ2 a…
A [Cu(II)16] wheel was isolated serendipitously from the reaction of acetylacetone dioxime with copper(ii) chloride and lanthanide ions in a reaction initially designed to produce heterometallic 3d-4f cages. The ligand has been transformed in situ to three different forms, all found within the [Cu16] wheel, with the o…
The temperature memory effect (TME) refers to the capability of shape memory materials to memorize the deformation temperature (Td). In this article, the TME of multiple-shape memory polymer based on a PMMA/PEG semi-interpenetrating polymer network (PMMA/PEG semi-IPN) and a PMMA-PCL covalently crosslinked polymer co-n…
The manipulation of charge transfer at CuPc/graphene interface has been demonstrated by treating pristine graphene with O₂ plasma. As revealed by in situ ultraviolet photoelectron spectroscopy measurements, a much stronger interfacial charge transfer occurs when the pristine graphene is exposed to O₂ plasma prior to t…
New gelators based on chiral triterpenoids were designed and synthesized. Different chiral properties of assembly in the organogels were observed. The nanofibers of the organogel in dimethylsulfoxide were used to engineer gold nanoparticles.
The detailed mechanism of hydrogen release in LiBH4-MgH2-Al composites of molar ratios 4 : 1 : 1 and 4 : 1 : 5 are investigated during multiple cycles of hydrogen release and uptake. This study combines information from several methods, i.e., in situ synchrotron radiation powder X-ray diffraction, (11)B magic-angle sp…
Several analytical techniques, such as N2 physisorption, X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), temperature programmed reduction (TPR) and chemisorption were employed to characterize the structure of Co/γAl2O3 catalysts used for the production of carbon nanotubes by methane vapor deposition.…
Molecular mechanics results show that a hexagonal boron nitride (h-BN) membrane can spontaneously assemble on the single-walled boron nitride nanotube (BNNT) in a scroll or helical manner, showing an interesting dependence on h-BN width. The size of BNNTs should meet the required conditions to guarantee self-assembly.…
The fabrication of yolk/shell spheres consisting of a magnetic core and a chitosan-derived porous carbon shell, and plenty of tiny copper <sub>core</sub> silver <sub>shell</sub> nanoparticles confined within the porous shell, as a catalyst for epoxidation reaction is reported.
A new environmentally benign and highly efficient reaction-controlled phase-transfer catalyst for olefin epoxidation, sulfide and alcohol oxidation was developed.
To provide safe drinking water, it is crucial to tackle both bacterial infection and inorganic pollutants.
Three tricolor luminous materials based on novel transparent hybrid films of polymer–lanthanide–zeolite A were assembled. The white light emission from the tricolor luminous materials can be tuned easily by adjusting the different concentrations of the doped ions and the excitation wavelength.
We report on successful aqueous processing of a lead free BZT–BCT composition with its dielectric properties unaffected by hydrolysis.
Among new therapies to fight tumors, immunotherapy is still one of the most promising and intriguing. Thanks to the ongoing structural elucidation of several tumor antigens and the development of innovative antigen carriers, immunotherapy is in constant evolution and it is largely used either alone or in synergy with…
Gold-dendrimer nanocomposites were obtained for the first time by a simple colloidal approach based on the use of polyamidoamine dendrimers with succinamic acid terminal groups and dodecanediamine core. Spherical and highly crystalline nanoparticles with dimensions between 3 nm and 60 nm, and size-polydispersity depen…
The fire retardant mechanism of ethylene vinyl acetate containing aluminum trihydroxide and melamine phosphate was investigated.
In the present study, we report the synthesis of glutathione (GSH) capped CdTe quantum dots (QDs) using the one-pot approach as well as their optical properties.
Basic results of experimental and theoretical research of creep processes and long-term strength of metals obtained by researchers of the Institute of Mechanics at the Lomonosov Moscow State University are presented. These results further develop and refine the kinetic theory of creep and long-duration strength propos…
Many stakeholders today consider power tower systems to be the most promising CSP technology for the future. Therefore much effort is spent to improve individual components and subsystems. While these are valuable steps towards cost reduction, it is also of great importance to perform an overall, i.e. ‘holistic’, syst…
