The nanotribological studies are needed to develop fundamental understanding of interfacial phenomena on a smaller scale in nanostructures used in magnetic storage systems and other industrial applications. In several fields of technical application, e.g., in the automotive or aircraft industries, the reduction of fri…
The relative ability of cholinium-([Ch](+))-based salts, including ionic liquids (ILs), to form biocompatible aqueous biphasic systems (ABS) with polyethylene glycols (PEGs) was deeply scrutinized in this work. Aqueous solutions of low molecular weight PEG polymers (400, 600, and 1000 g mol(-1)) and [Ch](+) salts of c…
Intercalation chemistry will soon be a hundred years old. The period of greatest activity in this field of solid state chemistry and physics was from about 1970 to 1990. The intercalation reactions are defined as topotactic solid state reactions and the products--the intercalation compounds--are clearly distinguished…
The aortic valve lies in a unique hemodynamic environment, one characterized by a range of stresses (shear stress, bending forces, loading forces and strain) that vary in intensity and direction throughout the cardiac cycle. Yet, despite its changing environment, the aortic valve opens and closes over 100,000 times a…
In this comprehensive review, we report on the preparation of graft-copolymers of cellulose and cellulose derivatives using atom transfer radical polymerization (ATRP) under homogeneous conditions. The review is divided into four sections according to the cellulosic material that is graft-copolymerised; (i) cellulose,…
We report a general strategy to create small-molecule fluorescent probes for the nucleus in living cells. Our strategy is based on the attachment of the DNA-binding Hoechst compound to a fluorophore of interest. Using this approach, simple fluorescein, BODIPY, and rhodamine dyes were readily converted to novel turn-on…
NaNbO 3 with cubic–orthorhombic surface-phase junctions were synthesized via a polymerized complex method. Improved charge separation meant that the mixed-phase NaNbO 3 exhibited much higher activity in CO 2 photoreduction than cubic and orthorhombic NaNbO 3 .
A review of synthetic routes to tin chalcogenides and CTZS, promising materials for sustainable photovoltaics.
Here, we report dicyanopyrazine (DPZ)-derived push–pull chromophores, easily prepared and tunable organic compounds, as new kinds of photoredox catalysts.

Hydrogen (H2) is a clean, portable and potentially inexhaustible energy source with the potential to become a panacea for clean energy generation. However, H2 has wide explosive concentration range (4–75 vol%), low ignition energy (0.02 mJ) and large flame propagation velocity. Due to its ultra small molecular size, c…
The synthesis of a mesoporous material with uniform mesopore diameters and crystalline MFI zeolite walls has been achieved, simply by seeding the multiammonium surfactant-directed synthesis with bulk zeolite crystals. The bulk seeds disappeared in the final product. As a result of seeding, the mesoporous zeolites coul…
Monomers structurally resembling lignin were prepared by reacting 4-hydroxybenzaldehyde, vanillin, syringaldehyde, (each bio-available) or ethylvanillin (synthetic) with dibromoethane, yielding dialdehydes CHO–Ar–OCH2CH2O–Ar–CHO. Condensation copolymerization with tetraols catalyzed by para-toluene sulfonic acid yield…
Novel poly(ether ether ketone) (PEEK) based nanocomposites with different contents of ZnO nanoparticles were prepared via cryogenic ball-milling followed by compression moulding. The nanoparticles were treated with a silane coupling agent to improve their dispersion and interfacial adhesion with the matrix. The morpho…
The environmentally friendly and low cost green synthesis of highly reduced graphene oxide using P. glutinosa
A highly selective colorimetric chemosensor LX was described, which could instantly detect Ni 2+ without interference by other cations.
UIO-66 nanoparticles with octahedral morphology and a high surface area have been prepared quickly and in high-yield by an additive/microwave method.
A series of nanometric isoreticular and/or functionalized analogues of the mesoporous environmentally-friendly iron(III) polycarboxylates MIL-100/101 have been successfully synthesized. Their exceptional pore size, of up to 68 Å, together with their relatively good stability in solvents, makes them promising candidate…
The working principle of semiconductor:insulator blends are discussed, examining the different approaches that have recently been reported in literature.
The interaction between light and matter is the fundamental aspect of many optoelectronic applications. The efficiency of such devices is mainly dictated by the light emitting properties of fluorophores. Unfortunately, the intensity of emission is adversely affected by surface defects, scattering and chemical instabil…
