A metal-free photocatalytic hydrogen evolution system was successfully fabricated using heteroatom doped graphene materials as electron-transfer co-catalysts and carbon nitride as a semiconductor. The catalytic role of graphene is significantly dependent on the heteroatom dopant of the graphene, such as O, S, B, N doped/undoped graphene co-catalysts, and N-graphene shows the best catalytic hydrogen evolution rate.

Spray drying is an important continuous industrial process for drying pumpable liquid formulations irrespective of their heat sensitivity, rheology, solids content and processing rate. Furthermore spray drying has the capability through drying chamber design, plant layout and mode of operation to produce dried products of specific particulate size and morphology. These are important aspects when spray drying technology is applied to the needs of customized powder manufacture. There are many examples in industry where spray dried powders have to meet stringent specifications set by such factors as end-product powder quality standards dictated by global competition,dry raw material characteristics required for optimum downstream processing, and dry materials handling to comply with environmental, health and safety issues. Spray drying is no longer regarded just as a convective industrial drying concept, but also as an integral part of modern manufacturing practices applying powder technology. This paper reviews the aspects of spray dryer design and operation for consideration when customized powder manufacture is involved.

We have developed a new 3D multi-physics multi-material code, ALE-AMR, which combines Arbitrary Lagrangian Eulerian （ALE） hydrodynamics with Adaptive Mesh Refinement （AMR） to connect the continuum to the microstructural regimes. The code is unique in its ability to model hot radiating plasmas and cold fragmenting solids. New numerical techniques were developed for many of the physics packages to work efficiently on a dynamically moving and adapting mesh. We use interface reconstruction based on volume fractions of the material components within mixed zones and reconstruct interfaces as needed. This interface reconstruction model is also used for void coalescence and fragmentation. A flexible strength/failure framework allows for pluggable material models, which may require material history arrays to determine the level of accumulated damage or the evolving yield stress in J2 plasticity models. For some applications laser rays are propagating through a virtual composite mesh consisting of the finest resolution representation of the modeled space. A new 2nd order accurate diffusion solver has been implemented for the thermal conduction and radiation transport packages. One application area is the modeling of laser/target effects including debris/shrapnel generation. Other application areas include warm dense matter, EUV lithography, and material wall interactions for fusion devices.

“Let them eat cake”： a retrospective service evaluation of Focus on Undernutrition in care homes. Introduction： Undernutrition is a major cause and consequence of poor health in older people, affecting 35% of residents in care homes. Focus on Undernutrition （FoU）, a dietetic service delivered by dietetic assistants uses a multifaceted approach to undernutrition management. This study aims to evaluate FoU’s impact on undernutrition outcome measures in care homes; including FoU’s influence on weight change in residents “at risk” of undernutrition, and prevalence of undernutrition and pressure ulcers （PU）. Methods： A retrospective pragmatic service evaluation was undertaken using pseudonymised data collected over 13 years on weight, undernutrition risk and PU from long-stay residents’ notes before and six months after training （FoU）. Results： Analysis completed on 104 homes, 4,315 residents （71.3% female; mean stay 10.8 （1-278） months） in County Durham. Following FoU a significant difference was identified for： improved rate of weight change for “at risk” residents （p 〈 0.001）. Undernutrition risk significantly influenced weight change （low： B1.04 kg, E0.01 kg; moderate： B-1.79 kg, E-0.38 kg; high： B-0.83kg, E1.00 kg, Bp 〈 0.001, Ep = 0.001）. Reduced undernutrition prevalence （p 〈 0.001） from 32.7% to 29.1% residents “at risk” of undernutrition （moderate： B13.1%, E8.9%; high： B19.6%, E15.9%）. Nutrition screening significantly improved （B76.3%, E98.7%, p 〈 0.001）, reduced prevalence PU （51%, p 〈 0.001）. PU prevalence significantly increased with undernutrition severity at baseline （p 〈 0.001）, but not following FoU （p = 0.233）（low： B5%, E2.3%; moderate： B6.9%, E1.6%; high： B10.5%, E3.9%）. Odds of developing PU reduced 53% （OR： 0.47）. B：baseline; E：evaluation; OR： odds ratio. Conclusion： These results demonstrate dietetic assistants delivering FoU significantly improves weight, undernutrition and PU prevalence in care homes. Indicating FoU is an effective model

过去几十年的博物馆研究和博物馆专业人员实践探索了博物馆传播的关键原则。博物馆展览建设有策划、设计、施工三个阶段。阐释策划阶段要弄清楚为什么要做这个项目,目标观众是谁,主题是什么,展览的背景情况是什么。阐释设计阶段就要了解展览内容,进行分众传播,具有可达性和真实性,而最核心原则是激发、关联和揭示。施工是实现一个高质量博物馆展览的最后阶段。这些阐释策划、阐释设计、内容创意和展览实施中的规范和标准是博物馆创建世界级展览最有效的方法,也是和观众沟通的有效手段。

The number and creativity of side channel attacks have increased dramatically in recent years. Of particular interest are attacks leveraging power line communication to 1) gather information on power consumption from the victim and 2) exfiltrate data from compromised machines. Attack strategies of this nature on the greater power grid and building infrastructure levels have been shown to be a serious threat. This project further explores this concept of a novel attack vector by creating a new type of penetration testing tool: an USB power adapter capable of remote monitoring of device power consumption and communicating through powerline communications.
