Biological small-angle X-ray scattering (SAXS) provides powerful complementary data for macromolecular crystallography (MX) by defining shape, conformation and assembly in solution. Although SAXS is in principle the highest throughput technique for structural biology, data collection is limited in practice by current…
The light output power and wall-plug efficiency of the Si nanocrystal (nc-Si) light-emitting diode (LED) were significantly enhanced by employing the multiple-luminescent structures. This improvement was attributed to a strong confinement of carriers in the SiNx luminescent layers containing the nc-Si due to the band…
Electronic absorption, magnetic circular dichroism (MCD), photoconductivity, and valence-band x-ray photoelectron (XPS) spectroscopic measurements were performed on epitaxial ${\text{Zn}}_{1\ensuremath{-}x}{\text{Mn}}_{x}\text{O}$ films to investigate the origin of the mid-gap band that appears upon introduction of ${…
Soft condensed matter physics relies on a fundamental understanding at the interface between physics, chemistry, biology, and engineering for a host of materials and circumstances that are related to, but outside, the traditional definition of condensed matter physics. Featuring contributions from leading researchers…
In this paper, we report the results of detailed studies on Mn and Cu substitution to Fe site of $\ensuremath{\beta}\text{-FeSe}$, namely, ${\text{Mn}}_{x}{\text{Fe}}_{1\ensuremath{-}x}{\text{Se}}_{1\ensuremath{-}\ensuremath{\delta}}$ and ${\text{Cu}}_{x}{\text{Fe}}_{1\ensuremath{-}x}{\text{Se}}_{1\ensuremath{-}\ensur…
A brief introduction to the development of electrospinning is given, and various apparatus to fabricate nanofibres or nanoporous materials are systematically reviewed with emphasis on the vibration electrospinning and melt electrospinning for enlarging electrospinability, siro-electrospinning for mimicking the spinnin…
Pickering emulsions stabilized by poly(sodium styrenesulfonate) (PSS) surface-modified LUDOX CL particles were used as templates for the layer-by-layer (LbL) deposition of polyelectrolytes and charged nanoparticles to form composite shells. The microcapsules resulting from repeated LbL coating with poly(diallyldimethy…
Resolving the tension: Complex particles with various shapes such as bullets, cylinders, discs, hearts, hexagons, and Janus particles can be synthesized by two different surface-tension-induced flow sequences (A and B; see picture, scale bars=100 μm). The particles produced by using this approach can be exploited as a…
We study the low-temperature heat transport of ${\text{HoMnO}}_{3}$ single crystals to probe the magnetic structures and their transitions induced by magnetic field. It is found that the low-$T$ thermal conductivity $(\ensuremath{\kappa})$ shows very strong magnetic-field dependence, with the strongest suppression of…
Graphene was discovered half a decade ago and proved the existence of a two-dimensional system which becomes stable as a result of 3D corrugation. It appeared very quickly that this exceptional material had truly outstanding electronic, mechanical, thermal and optical properties. Consequently a broad range of applicat…
The effect of finite temperature $T$ and finite strain rate $\stackrel{\ifmmode \dot{}\else \.{}\fi{}}{\ensuremath{\gamma}}$ on the statistical physics of plastic deformations in amorphous solids made of $N$ particles is investigated. We recognize three regimes of temperature where the statistics are qualitatively dif…
We report here the electrochemistry and electrogenerated chemiluminescence (ECL) of a red-emitting dithienylbenzothiadiazole-based molecular fluorophore (4,7-bis(4-(4-sec-butoxyphenyl)-5-(3,5-di(1-naphthyl)phenyl)thiophen-2-yl)-2,1,3-benzothiadiazole, 1b). 1b contains two substituted thiophene groups as strong electro…
A large number of polyhalides, especially polyiodides, have been discovered and studied, but definitive studies on polybromides remain scarce. Br(3)(-) is the only monovalent polybromide with a known structure. Higher-order monovalent polybromide anions have been proposed but not structurally confirmed as discrete spe…
We present a confined Kolsky bar device capable of applying hydrostatic confining pressures and dynamic axial shear loads to right-circular cylindrical samples. The conventional Kolsky bar apparatus is modified by adding a high-pressure hydraulic chamber capable of applying radial confining pressures up to 400 MPa to…
The interaction of OH-containing compounds with calcite, CaCO(3), such as is required for the processes that control biomineralization, has been investigated in a low-water solution. We used ethanol (EtOH) as a simple, model, OH-containing organic compound, and observed the strength of its adsorption on calcite relati…
Chalcogenide nanostructures offer promise for obtaining nanomaterials with high electrical conductivity, low thermal conductivity, and high Seebeck coefficient. Here, we demonstrate a new approach of tuning the Seebeck coefficient of nanoplate assemblies of single-crystal pnictogen chalcogenides by heterostructuring t…
Industrial applications of plasma-enhanced chemical vapour deposition (CVD) diamond grown on large area substrates, 3D shapes, at low substrate temperatures and on standard engineering substrate materials require novel plasma concepts. Based on the pioneering work of the group at AIST in Japan, the high-density coaxia…
We review the progress towards developing epitaxial graphene as a material for carbon electronics. In particular, we discuss improvements in epitaxial graphene growth, interface control and the understanding of multilayer epitaxial graphene's (MEG's) electronic properties. Although graphene grown on both polar faces o…
In this paper we discuss and review results of recent studies of epitaxial growth of graphene on silicon carbide. The presentation is focused on high quality, large and uniform layer graphene growth on the SiC(0 0 0 1) surface and the results of using different growth techniques and parameters are compared. This is an…
We describe a two-step synthesis of pure multiwall MoS2 nanotubes with a high degree of homogeneity in size. The Mo6S4I6 nanowires grown directly from elements under temperature gradient conditions in hedgehog-like assemblies were used as precursor material. Transformation in argon-H2S/H2 mixture leads to the MoS2 nan…
