作为最为大众所熟知的电子消费设备，电视技术的快速发展对其供电需求产生了重要影响。由于LED能极大地提高电能使用效率并实现超薄的设计形式，已成为背光的优质光源。同时，消费者也希望电视生产商能够生产更多40寸甚至更人面板尺寸的液晶电视。因此，如今的电视背光系统的电源必须能够驱动大量的并联LED串，提供非常高的输出电压和负载电流。电视主板上的直流电源通常为12V或24V，但驱动LED串的电压则需达到60V甚至更高。

Catalytic Synthesis of Salicylate Esters over Cordierite Honeycomb Coated with Mo (VI)/ZrO2

引用

Modern Research in Catalysis 2013年第2期2卷 39-41页

作者： manjunatha Shyamsundar Sathgatta Z. M. Shamshuddin Nabisab Mujawar Mubarak Srinivas R. Prathap Chemistry Research Laboratory HMS Institute of Technology Tumkur India Department of Chemical Engineering University of Malaya Kualalumpur Malaysia

Solid acids such as ZrO2 & Mo (VI)/ZrO2 were coated on a honeycomb monolith by impregnation method. These catalytic materials were characterized by NH3-TPD, PXRD and SEM techniques. Salicylate esters were synthesized via transesterification of methyl salicylate with different alcohols over these catalytic materials. An excellent yield of Salicylate esters was obtained under specific reaction conditions. A correlation between the surface acidity, PXRD phase and catalytic activity of Mo (VI)/ZrO2 was observed. The thermally regenerated catalytic material was reused repeatedly with a consistent high yield of salicylate esters. The honeycomb coated with zirconia catalysts were found to be economical, efficient and ecofriendly (3E concept).

Metal matrix composites (MMCs) are gaining widespread recognition in numerous technological fields owing to its superior mechanical properties when compared with conventional metals/alloys. The aluminium based hybrid composites are increasingly being used in the transport, aerospace, marine, automobile and mineral processing industries, owing to the improved strength, stiffness and wear resistance properties. In the present research work, the composites were prepared using the liquid metallurgy technique, in which 2 - 10 weight percentage of Al2O3 particulates and 1 weight percentage of Graphite were dispersed in the base Al6061 alloy. The Casted hybrid composites were subjected to machining process to prepare the specimens according to ASTM standards. Then, the prepared specimens are subjected for assessing the Microstructure followed by its Mechanical behaviors such as, Hardness, Tensile strength, Compressive strength respectively. The microstructure analysis confirms that homogenous distribution of Al2O3 and Gr in the Al6061 matrix alloy and there was a momentous enhancement in decisive tensile strength, compressive strength and hardness properties of the hybrid composite. However, a substantial increase in the compressive strength was noticed in graphite reinforced composites as the graphite content was increased and there was a significant diminution in hardness coupled with monotonic increases in the ductility. Further, the ultimate tensile strength and compressive strength of the composite was noticed;thus the outcome of the study will provide explicit rationalizations for these observable facts. Therefore, the proposed way out in the study can provide ample of approaches to minimize the existing problem by employing this newer hybrid composites.

Ca ions are important second messengers in many signal transduction pathways. They participate inessentially every cellular processes, ranging from gene regulation and protein trafficking, to cell differentiationand apoptosis, and to membrane excitability and cell motility. In general, there are two sources of thesesignaling molecules in the cell:channels in the plasma membrane (PM) that open to allow external Ca toflow into the cytoplasm, and internal stores in the form of endoplasmic reticulum (ER) or sarcoplasmicreticulum (SR) that release Cainto the cytosol. Junctional membrane complexes between PM and ER/SR arepresent in all excitable cells, and provide effective mechanism for cross-talk between Ca-dependentchannels/transporters on the plasma membrane and Ca release channels on the intracellular membrane.

以氮丙啶（ethyleneimine）0.2％和0.4％两种浓度,1小时和3小时两种浸种时间,对引种于印度尼西亚南加里曼丹潮汐沼泽地的8个品种的干种子进行了处理,以引变早熟、矮秆突变而不影响对沼泽条件的耐受性.M1代种子的发芽率与其颖花育性间具有正相关关系,今后进行试验时可用来确定适宜的处理剂量。从两种有效处理（0.2％,3小时;和0.4％,3小时）的M1代植株所选单穗繁殖得1844个M2后代供作进一步筛选。1979年旱季在自然长日照条件对M2家系进行筛选结果,从品种Siyam Halus的突变（IR29386）中获得了对光周期不敏感的类型,并从品种Siyam Kuning（IR30446）中获得中秆而对光周期敏感的突变。在湿季,把早熟突变体繁殖为M3植株后代以纯育其早熟性;即令在短日照条件下,它们较其亲本品种约可早熟1个月。中秆型突变体的株高低于其亲本约35厘米,而且仍保持着亲本固有的大多数性状。分蘖力得到了增进而颖花数略有减少。据初步鉴定,突变体能很好地适应潮汐沼泽地条件,唯较原品种Siyam Kuning迟熟。对此将于1981年采用几种播种期作进一步研究.如果氮丙啶用于转变植株高度具有特效,应认为是今后改良具有特适性品种的手段.

Long-term operational stability remains the primary concern for perovskite solar cells. Consequently, there is a quest for searching for new compositions that enable stable and efficient perovskites. We report a new molecular-level interface engineering strategy using a multifunctional ligand that augments long-term operational and thermal stability by chemically modifying the formamidinium lead iodide rich photoactive layer. The surface derivatized solar cells exhibited high operational stability(maximum powering point tracking at 1 sun) with a stabilized T80(the time over which the device efficiency reduces to 80% of its initial value of post-burn-in) of ≈5950 h at 40 oC and stabilized efficiency over 23%. The origin of high device stability and performance is correlated to the nano/subnanoscale molecular level interactions between ligand and perovskite layer, which is corroborated by comprehensive multiscale characterization. Our results provide key insights into the modulation of the grain boundaries, local density of states, surface bandgap, and interfacial recombination. Chemical analysis of the aged devices showed that interface passivation inhibited ion migration and prevented photoinduced I2 release that irreversibly degrades the perovskite. This study shows that passivating ligands have the potential to overcome stability issues associated with the high performing hybrid perovskite compositions, thus allowing a step closer to achieving long-standing stability of perovskitebased solar cells.
