We describe here a novel biomolecule-assisted hydrothermal strategy for the synthesis of two-dimensional ultra-thin α-Co(OH)2 mesocrystal nanosheets. These unique ultra-thin α-Co(OH)2 mesocrystal nanosheets have good electrical conductivity and are highly attractive for application in electrochemical capacitors due to…
A novel method for preparing SOx removing (ReSOx) catalysts for the fluid catalytic cracking (FCC) process, based on multimetallic layered double hydroxides (LDHs), is presented. The synthesis procedure is industrially feasible and environmentally friendly. Ceria is incorporated in varying amounts as oxidation promote…
Two polynuclear mixed-valence manganese clusters, [Mn(13)] and [Mn(16)], containing mixed chelating ligands were synthesized and structurally characterized. The alternating current (AC) susceptibilities of both complexes reveal nonzero frequency-dependent out-of-phase (χ(M)'') signals.
Encapsulation into liposomes has been developed in order to allow protection of therapeutical agents against enzymatic degradation, and to reduce doses and toxic side effects. Selective, targeted and controlled release of the drug out of the lipid vesicle is still, however, difficult to achieve. Meanwhile, thanks to t…
The diatoms are an ecologically important group of algae that have been extensively studied by ecologists and taxonomists. However, the large-scale patterns of diatom distribution and the factors underlying this distribution are largely unknown. The aims of this study were to identify the large-scale spatial patterns…
A seeded heteroepitaxial growth of ZnO nanorods selectively on TiO(2) nanorod tips was achieved by restricting crystal growth on highly hydrophobic TiO(2) nanorod film surfaces. Intriguing light harvesting performance and efficient charge transport efficiency has been found, which suggest potential applications in pho…
Fresnoite (Ba2TiSi2O8–BTS) thin films were grown on fused quartz, silicon (100), MgO (100), and a-plane sapphire by pulsed laser deposition, and crystallized by subsequent thermal or flash lamp annealing. The corresponding texture evolution of the BTS thin films was studied by X-ray diffraction. The preferential (001)…
Ladder-like polysilsesquioxanes containing chiral groups and ammonium chloride groups as side chains were prepared by the polymer reaction method. The chiralities of the resulting PSQs in methanol were induced to the anionic achiral porphyrin such as tetraphenylporphine tetrasulfonic acid (TPPS) while maintaining the…
We have studied the nucleation kinetics in the bulk as well as at the container walls of a charged sphere colloidal model system under salt-free conditions close to the fluid–crystal phase boundary. We determined time resolved nucleation rate densities for heterogeneous nucleation on the wall, the corresponding nuclea…
The development of tissue-engineered vascular grafts for use in cardiovascular surgery holds great promise for improving outcomes in pediatric patients with complex congenital cardiac anomalies. Currently used synthetic grafts have a number of shortcomings in this setting but a tissue engineering approach has emerged…
Magnetic fluorescent FePt@CdSe core–shell nanoparticles were directly synthesized by sequential addition of precursors and using tetraethylene glycol as a solvent and a reducing agent. The core–shell NPs were successfully formed over a wide range of temperature (240–300 °C). The size and composition of the FePt core w…
Horseradish peroxidase (HRP) is immobilized on periodic mesoporous organosilicas (PMO) for the first time, and the enzyme activity improved, especially on MI100, prepared with 100% organic silica precursor, the enzyme activity is enhanced 110% compared with free HRP in solution. Besides, the stability of immobilized H…
Though the fabrication of ZnO nanostructures is economical and low temperature, the lack of a facile, reliable and low temperature methodology to tune its electrical conductivity has prevented it from competing with other semiconductors. Here, we carried out surface modification of ZnO nanowires using ammonia plasma w…
Oxidation is an important route for the activation of chemical feedstocks for the synthesis of chemical intermediates. Alkene epoxidation by the electrophilic addition of oxygen to a carbon–carbon double bond is a major challenge in oxidation catalysis. In particular it is important to use molecular oxygen as the oxid…
The microstructure of polymer-grafted nanoparticles in polymer melts that are chemically identical to the brush was investigated using ultra-small angle X-ray scattering (USAXS). The dispersions were thermodynamically stable. Particle size and melt molecular weight were varied such that the particle softness, L*, or t…

In this theoretical paper, we interpret and predict the optical properties of nanodiamond (ND) particles containing different luminescence centres. Specifically, we modelled nitrogen, nickel and chromium embedded into the ND crystal lattice. In the case of nitrogen centres containing ND particles, we also studied the…
The electronic structure and optical properties of a one-electron quantum dot (QD) were investigated by assuming a spherically symmetric confining potential of finite depth. In this particular case CdSe is surrounded by ZnS. The energy eigenvalues and wave functions dependence on QD dimension were calculated by using…
Remarkable enhancement and quenching of photo-luminescent emissions have been found in various mixed-lanthanide carboxylate polymers. In (Eu0.1:Tb99.9)2(2,2-biphenate)3(H2O)2 the Eu emission is comparable to the Eu homo-polymer, whilst the original Tb emission is reduced by ca. 80%. Either sensitized energy transfer o…
Bimetallic nanoparticles are important because they possess catalytic and electronic properties with potential applications in medicine, electronics, and chemical industries. A galvanic replacement reaction synthesis has been used in this research to form bimetallic nanoparticles. The complete description of the synth…
