dramatic reduction in threading dislocation density and stress-relaxation was simultaneously achieved in GaN epilayer using a silica nanosphere embedded structure on V-groove patterned sapphire substrate by metal-organic chemical vapor deposition. By depositing silica nanospheres at two different instances during a growth process, a two-step growth that included selective area growth and lateral overgrowth was initiated. This approach led to GaN template of high crystal quality, which was confirmed from x-ray diffraction rocking curve and micro-Raman measurements and further corroborated by transmission electron microscopy. GaN light-emitting diode fabricated by this strategy showed a significant enhancement in the light output power. (C) 2014 Elsevier B.V. All rights reserved.

<P>Vibrio parahaemolyticus is recognized as a human foodborne pathogen that is mostly associated with seafood. This pathogen can form a mature biofilm on food and food contact surfaces during food processing. The present study investigated V. parahaemolyticus biofilm formation at various temperatures on shrimp, crab, and stainless steel coupons, using the biofilm formation index (BFI) method on microtiter plates. The results were also confirmed by field emission scanning electron microscopy. Both the BFI values and cultural counts revealed that V. parahaemolyticus biofilm formation was stronger at higher temperatures than at lower temperatures. Biofilm formation differed according to the growth surface type and growth temperature. It was found that higher temperatures (15-37 degrees C) induced stronger biofilm formation whereas 4 and 10 degrees C resulted in attachment of the bacterial cells as monolayers. It could be concluded that temperatures of 25-37 degrees C result in significantly stronger biofilm formation as well as exoprotease and AI-2 production on food and food contact surfaces, indicating that these temperatures might be threatening conditions for food safety.

Infrared photoluminescence from lead sulfide quantum dots in glasses enriched in sulfur
Han, N.,Liu, C.,Zhang, J.,Zhao, X.,Heo, J.,Jiang, Y. North-Holland 2014 Journal of non-crystalline solids Vol.391 No.-
Formation of PbS QDs in the glasses containing a small amount of lead oxide was examined. Oversaturation of sulfur only was sufficient to promote the formation of PbS QDs in the glasses. Upon thermal treatment, absorption of PbS QDs was tuned from 824nm to 2213nm. Infrared photoluminescence, especially, mid-infrared photoluminescence from PbS QDs was observed in the range of 1008nm to 2182nm. Ostwald ripening of PbS QDs occurred when the heat-treatment temperature was 530<SUP>o</SUP>C or 540<SUP>o</SUP>C, and led to the decrease in the absorption coefficients and splitting of the photoluminescence bands.
Symmetry, ratio and proportion in Scottish clan tartans - Templates for modern designers -
Hann, Michael,Wang, Chaoran The Costume Culture Association 2016 服飾文化硏究 Vol.24 No.6
It is common knowledge that a conventionally woven textile consists of two assemblies of parallel threads (warp and weft), one interlaced with the other at ninety degrees. Where each of the two assemblies is arranged in a particular colour sequence, a check design, known as a 'tartan', may be created. Although similar check-type cloths have been produced worldwide, it is the tartans of Scotland which have received most attention and it is here that a complex set of rules evolved and tartans of different types became associated traditionally with different regions, family groups or 'clans'. There is an impressive array of publications focused on the identification of tartans and their clan associations. This paper explains the nature of tartans, analyses typical surface structures, ratios and proportions, and suggests possible avenues of use for modern designers. The principal sources of data were a collection of tartans held at ULITA - An Archive of International Textiles (University of Leeds, UK) and Stewart's 1974 publication The Setts of Scottish Tartans. Based on the observation that divisions into halfs and thirds were dominant, a series of templates is presented with the intention of developing an awareness among designers that ratios and proportions used in familiar or traditional frameworks can be employed in a modern context.
제올라이트 분리막: 조성 변경을 통한 분리막 성질의 조절

분리막을 이용한 분리 기술은 에너지 소요가 적다. 제올라이트를 기반으로 제작한 분리막의 경우, 결정 구조 내에 작은 분자 크기의 기공을 갖고 있어 이를 이용하여 가혹한 조건에서도 분리가 가능하기 때문에, 그 관심도가 높다. NaA (LTA 유형의 제올라이트) 제올라이트의 경우, 산업적으로 유기 용매에서 수분을 제거하는 데 많이 사용되는 데, 해당 기공 크기나 열적/수열안정성은 제올라이트 내부나 외부의 원소를 바꿔줌으로써 조절할 수 있다. 더 작은 0.28 nm 크기를 지닌 SOD 유형의 제올라이트의 경우, 수소나 물 분리에 적합하여 그 관심도가 높아지고 있으며, 이 제올라이트 유형 또한, 이온 교환과 같은 방법으로 성질을 변경할 수 있다. 제올라이트는 주변 기술 및 공정 조건에 맞게 작은 분자들을 적절하게 분리할 수 있는 분리막을 창출할 수 있다는 장점을 지닌 소재이다. Membrane separation is a technology of low energy consumption. Membranes made of zeolites are of great interest because their fixed and open pores in the size of small molecules inside crystalline structures allow separation processes under harsh conditions. While zeolite NaA (LTA-type) is industrially used for dewatering of organic solvents, its pore size and thermal and hydrothermal stability can be tuned by exchange of framework and extra-framework elements. SOD with pores of only 0.28 nm is of great interest for H2- und H2O-separation and also can be tuned by ion exchange. Zeolites open the opportunity to create membranes of adapted separation behavior for small molecules in conditions of surrounding technical processes.

This paper explores our project to adapt the Singaporean Wayang Kulit puppet-shadow play to Virtual Reality (VR). Although the decline in popularity of such traditional performances is often attributed to the rise of modern media and digital art forms, we argue that immersive media forms should instead be seen as offering an opportunity to preserve such artforms and increase their relevance for modern audiences. This paper will outline the process of visual and narrative development, highlighting both the value of translating traditional forms of performance to immersive media, and the importance of partnership and collaboration in delivering such initiatives. Attention will be paid to how traditional stylistic conventions and customs can best be applied and adapted to the context of immersive media, demonstrating how a respectful transposition of the traditional puppet play to VR can evolve the artform as a living tradition and preserve the underlying cultural heritage.
