We studied ZnO growth on 3C-SiC(001)/Si(001) templates. In-situ reflection high- energy electron diffraction (RHEED) observations implied that ZnO grown on 3C-SiC(001) had a critical thickness (50 nm). From a structural characterization by using X-ray diffraction, we revealed that ZnO films thinner than the critical thickness grown on 3C-SiC(001) had a [10-11] orientation with 4-fold in-plane symmetry. On the other hand, ZnO films thicker than the critical thickness consisted of [10-11] and [0001] orientations. Also, the portion of [0001] oriented ZnO increased with the layer thickness. Possible interface configurations of ZnO(10-11)/3C-SiC(001) and ZnO(0001)/ZnO(10-11) are suggested.

We have investigated the structural properties of CrN layers grown on (0001) Al2O3 substrates by molecular-beam epitaxy. The CrN layers of high-crystal quality are obtained at a low growth temperature of 500 C. X-ray diraction studies indicate that the CrN layers grow along the <111> direction with a cubic structure. In-situ reflection high-energy electron diraction investigations clarify that the CrN layers have the following epitaxy relationship with the Al2O3 substrates: <12- 1> of (111) cubic CrN // <11-20> of (0001) corundum Al2O3 and <101> of (111) cubic CrN // <1-100> of (0001) corundum Al2O3. Based on the above results, the mismatch of the in-plane lattice spacing between the CrN layers and the Al2O3 substrates is evaluated to be around 6.6 %. When the CrN layers are used as the buer layers for GaN growth, the GaN layers grown on the CrN layers show well-resolved excitonic emission lines in the photoluminescence spectra, whereas the GaN layers grown without the CrN layers exhibit a broad near-band-edge emission. It is suggested that CrN buers are eective in relieving the lattice mismatch between Al2O3 substrates and GaN layers.
Technological demands of meat processing-An Asian perspective
Zhang, W.,Naveena, B.M.,Jo, C.,Sakata, R.,Zhou, G.,Banerjee, R.,Nishiumi, T. Applied Science Publishers 2017 Meat science Vol.132 No.-
<P>A rapid increase in the economy, population, industrialization, and urbanization of Asian countries has driven the fast development of their meat industries over recent decades. This consistent increase in meat production and consumption in Asia has been the major cause for the development of the global meat industry. Meat production methods and consumption are very diverse across different regions and countries in Asia, and thus, it is impossible to cover the technological demands of all Asian countries in this review. Here, we have mainly highlighted the differences in meat production methods and consumption in Asia during recent decades and the meat technology demands of three east Asian countries, namely China, Korea, and Japan, and one south Asian country, India. A brief introduction of the meat industry, in particular the production and consumption trend in these countries, is provided in this article. The technology demands for fresh and processed meat products are then reviewed.</P>
