2019 年6 月，联合国再生能源咨询机构REN21 发布《2019年全球可再生能源现状报告》，这是自2005 年来该机构发布的第15 期年度报告，报告详细分析了2018 年全球可再生能源发展现状、政策框架、投资趋势、能源系统整合和使能技术发展，以及能源效率等方面的情况。从中可以看出，可再生能源发电量占比不断提高，但在供暖和制冷、交通运输等部门的应用发展仍然缓慢。越来越多的国家开始制定支持可再生能源发展的政策和目标，但全球投资尤其是发展中国家的投资有放缓趋势。赛迪智库材料工业研究所对该报告进行了编译，期望对我国有关部门有所帮助。

United states is one of the major consumers of biostimulant in North America . Biostimulan ts are relatively less popular. However the United States with its highly evolved agricultural sector has been adapting to the natural and organic way of farming. Hence, the region is witnessing induced consumption of biostimulants.  Over the years, change in various factors such as total area under cultivation, price of the product, and crops cultivated have been influencing the market pattern of biostimulants in the country. The use of biostimulants for fruits, vegetables, cereals, and pulses is growing strongly owing to changing consumption patterns of fruits and vegetables without the risk of pesticide residues and with increased nutritional value.

The United States nematicides market is majorly dominated by fumigant type nematicides, cornering 44.2% share in the overall nematicide market in 2018. For instance, California, one of the largest markets for nematicides, has been widely applying soil fumigants such as sodium tetrathio to treat nematodes present in vineyards across the state. Fruits and Vegetables were estimated to have the major chunk of share by way of application in the United States nematicide market. The increasing yield losses in tomatoes has led to the extensive use of root-knot nematodes and sting nematodes to mitigate the blighting of crops by nematode attacks. Furthermore, soil fumigation is a well-applied method on US farm fields, while the usage of non-fumigant nematicides is limited across the country. Increasing use of nematicides on vegetables, growing need for higher agricultural productivity and growing, and the advent of bio-nematicides is expected to stipulate the market growth. However, restriction on the usage of chemical/synthetic products, and increasing research and development costs are the likely factors restraining the growth of the market.

11 月，石化行业生产继续增长，炼油利润小幅回升，成品油消费景气度下降。具体来看，国际布伦特油价环比上涨 5.5%，原油生产环比增加 0.9%，继续保持稳步增长，原油进口继续保持 10%以上增速；下游化工品价格创年内新低；投资方面，石油加工、炼焦及核燃料加工业固定资产投资额累计同比增长 14.5%；供应方面，炼油利润回调，加工原油 5784 万吨，环比下降 3%；汽油、柴油产量环比下降，煤油环比上升，乙烯环比增加 22%；进出口方面，汽油出口创历史新高；需求方面，汽车行业低迷等因素导致汽油消费量呈持续下滑态势，工业疲软，继续压低柴油消费。价格方面，11月份成品油价格上调 2 次，汽柴油累计上涨 175 元/吨和 170 元/吨。

11 月份，化工行业运行整体依旧缓慢，工业增加值增速稍有回升；1～11 月，化学原料和化学制品制造业工业增加值同比增长 4.4%；出厂价格指数总体延续上年末下滑趋势，11 月化学原料和化学制品制造业出厂价格指数为 93.6 点；行业投资增速继续回落，1～11 月化学原料和化学制品制造业固定资产投资同比增长4.6%；化工行业营收增速止增转降后降幅继续扩大，利润终结增长开启下滑走势，1～11 月行业利润同比大幅减少 23.3%，较 1～10 月收窄 2.0 个百分点。

Automotive lightweight materials have been witnessing robust growth during the past couple of years, due to the increasing demand for luxurious, low-on-emission, safe, and high-performance vehicles. As a result, suppliers and manufacturers have introduced various solutions that not only help OEMs meet continually tightening regulations, but also satisfy the widening range of consumer personal taste. TPVs have superior strength, high-temperature mechanical properties, hot oil and solvent resistance, and better compression set than partially-cured material. These materials are blends of elastomers, typically rubbers, including EPDM, EPR, SBS, polybutadiene (BR), or butyl rubber (IIR), dispersed in a relatively small amount of thermoplastic matrix, typically polyethylene or polypropylene. Thermoplastic vulcanizates contain 60-70% EPDM and 30-40% impact polypropylene. Typical TPV applications in the automotive industry include hose coverings, gaskets, seals, convoluted boots, vibration dampeners, air inlet duct covers, bushings, strut covers, ignition components, and window seals. Cost is the biggest advantage, with TPVs being 10-30% lower than EPDM, coupled with lower weight, improved design flexibility, and recyclability. Furthermore, the light weight of TPV enables more fuel-efficient vehicles. Every 10% reduction in vehicle weight is estimated to result in a 5-7% reduction in fuel usage.

One of the major applications of high-purity alumina (HPA) is in the production of synthetic sapphire, which is used as a substrate in LED preparation. Production of synthetic sapphire starts with a seed sapphire crystal, a mixture of high purity alumina and un-crystallized sapphire material (crackle), which are heated in a crucible. Currently, sapphire is the most preferred substrate in the LED manufacturing, as it much cheaper than other substrates, such as Silicon Carbide, and Gallium Nitride. Currently, more than 50% of the global HPA production is used in LED manufacturing. However, the increasing demand for LED lighting is expected to further drive the market studied, during the forecast period. LED bulbs offer around 85% more electricity saving in comparison to conventional bulb. It also has an average life span of around 50,000 operating hours, which is 2- 4 times as long as most fluorescent, metal halide, and even sodium vapor lights, and 40 times as long as an average incandescent bulb.
