In this work, Bi0.5Sb1.5Te3 powders were coated with various nickel (Ni) contents by chemical plating, and then consolidated into bulk by hot pressing. The results show that Ni particles uniformly coat on the surface of powders and then transform into NiTe2 during the sintering process, after that NiTe2 mainly concentrated at the grain boundaries of bulk. With Ni content increasing, the resistivity of bulk samples and Seebeck coefficient decreased rapidly while thermal conductivity increased.

The basic question of metal cluster research is the following: How do the macroscopic metallic properties – conductivity, optical lustre, chemical and catalytical reactivity, magnetism, malleability and ductility – evolve as a function of cluster size starting from the electronic states of the atom? It turns out that in a cluster of 20-40 atoms most of what we acknowledge as «metallic» is already fully developed.This is the reason why the beautiful chemistry of metal cluster complexes has not contributed to an understanding of the transitionfrom the atom to the bulk: The chemical interaction o

Microbial conversion is a key process in the biosynthetic routes of steroid medicine.The whole process of bioconversion includes two essential steps: (1) enzymatic reaction step where the enzyme-catalyzed substrate transformation takes place inside the cells, and (2) diffusion step that includes the diffusion of substrate molecules from the surface of solid substrate particles into bulk media (i.e., the solubilization of solid substrate), the diffusion of solubilized substrate molecules from bulk media into cells, and the diffusion of formed product molecules from inside cells into bulk media.

In this paper, based on Kubo's formula and the QCD low energy theorem, we propose a direct formula for calculating the bulk viscosity of QCD at finite chemical potential μ and zero temperature. According to this formula, the bulk viscosity at finite μ is totally determined by the dressed quark propagator at finite μ. We then use a dynamical, confining Dyson–Schwinger equation model of QCD to calculate the bulk viscosity at finite μ. It is found that no sharp peak behavior of the bulk viscosity at finite μ is observed, which is quite different from that of the bulk viscosity at finite temperatu

The stoichiometry of HCVD crystals can be controlled by changing the C/Si flow ratio and can be kept constant throughout growth, in contrast to the Physical Vapor Transport technique.

Résumé :
Based on detailed analysis of the risk of bulk chemical tanker transportation, a societal risk acceptance criterion is established. The criterion takes advantage of formal safety assessment (FSA) methodology, which is widely used to analyze risk in maritime industry. In the end of this paper, the negligible range, the ALARP range and the intolerable range of bulk chemical tanker in China are estimated in the criterion.

Résumé :
Abstract. We present a novel kinetic multi-layer model that explicitly resolves mass transport and chemical reaction at the surface and in the bulk of aerosol particles (KM-SUB). The model is based on the PRA framework of gas-particle interactions (Pöschl et al., 2007), and it includes reversible adsorption, surface reactions and surface-bulk exchange as well as bulk diffusion and reaction. Unlike earlier models, KM-SUB does not require simplifying assumptions about steady-state conditions and radial mixing. The temporal evolution and concentration profiles of volatile and non-volatile species

Résumé :
Abstract. We present a kinetic double layer model coupling aerosol surface and bulk chemistry (K2-SUB) based on the PRA framework of gas-particle interactions (Pöschl et al., 2007). K2-SUB is applied to a popular model system of atmospheric heterogeneous chemistry: the interaction of ozone with oleic acid. We show that our modelling approach allows de-convoluting surface and bulk processes, which has been a controversial topic and remains an important challenge for the understanding and description of atmospheric aerosol transformation. In particular, we demonstrate how a detailed treatment of
