The National Institute for Occupational Safety and Health (NIOSH) Engineering and Physical Hazards Branch (EPHB) and the University of Massachusetts Lowell (UMass Lowell) Environmental Health and Safety Team assessed nanoparticle emissions in a chemical laboratory at UMass Lowell. The laboratory conducted bench-top scale product development using 20-30 nm diameter bundles of single-walled carbon nanotubes (CNTs). The tasks evaluated in this study included weighing, mixing, sonicating, coating, drying, and cutting, which are common activities in most research and commercial production facilities. Weigh-out, mixing, and sonication were conducted on the bench-top without engineering controls, while coating, drying, and cutting were conducted inside a fume hood or a ventilated enclosure. The study results provide information on exposure potential and control for common nanomanufacturing processes.

发改委网站7月21日消息，国家发展改革委发出通知，决定将汽、柴油价格每吨分别降低245元和235元，测算到零售价格90号汽油和0号柴油（全国平均）每升分别降低0.18元和0.20元，调价执行时间为7月21日24时。点评：此次成品油价格调整幅度，是按照现行成品油价格形成机制，根据7月21日前10个工作日国际市场原油平均价格变化情况计算，并累加上个调价周期未调价金额确定的。7月上旬以来，受地缘政治缓和等因素影响，国际市场油价震荡下行，前10个工作日平均价格出现较大幅度下跌。

In support of the Bioenergy Technologies Office, the National Renewable Energy Laboratory (NREL) and the Pacific Northwest National Laboratory (PNNL) are undertaking studies of biomass conversion technologies to hydrocarbon fuels to identify barriers and target research toward reducing conversion costs. Process designs and preliminary economic estimates for each of these pathway cases were developed using rigorous modeling tools (Aspen Plus and Chemcad). These analyses incorporated the best information available at the time of development, including data from recent pilot- and bench-scale demonstrations, collaborative industrial and academic partners, and published literature and patents. This technology pathway case investigates converting woody biomass using ex-situ catalytic fast pyrolysis followed by upgrading to gasoline-, diesel-, and jet-range hydrocarbon blendstocks. Technical barriers and key research needs that should be pursued for this pathway to be competitive with petroleum-derived blendstocks have been identified.

Process designs and preliminary economic estimates for each of these pathway cases were developed using rigorous modeling tools (Aspen Plus and Chemcad). These analyses incorporated the best information available at the time of development, including data from recent pilot- and bench-scale demonstrations, collaborative industrial and academic partners, and published literature and patents. The economic results of these analyses are in the process of further refinement and will be published in FY13 and FY14 design reports. This report summarizes the preliminary technical data used for the models and identified data gaps. This technology pathway case investigates the cultivation of algal biomass followed by further lipid extraction and upgrading to hydrocarbon biofuels. Technical barriers and key research needs have been assessed in order for the algal lipid extraction and upgrading pathway to be competitive with petroleum-derived gasoline-, diesel-, and jet-range hydrocarbon blendstocks.
