Inorganic phosphate is a common nutrient that is applied as a fertilizer to both agricultural fields as well as urban settings such as private yards, public parks and other urban landscaping. While phosphate typically binds tightly to soil, movement of phosphate off of application sites can occur through soil erosion. The soil and its bound phosphate can then end up in surface waters such as rivers and lakes. phosphate found in surface water bodies exists both as bound to the suspended clay as well as that free in solution. Elevated phosphate concentration in surface waters can lead to algal blooms and eutrophication. While the phosphate bound to clay in suspension in surface water bodies can be removed by commercially available polymer flocculants, the phosphate that is free in solution is more challenging as it is usually found in low concentrations and other anionic salts are generally present in higher concentrations. To remove phosphate from contaminated water systems, where other anions exist at higher concentrations, it is favorable to have a method of removal that is selective for phosphate. As a proof of principle, thiourea derivatized polymer flocculants were examined for the selective removal of phosphate in the presence of competing anions. The polymer flocculants exhibited selectivity for phosphate through hydrogen bonding and were effective at removing up to 43% of phosphate from simulated wastewater. computational studies and pan>p>1p>pan style="font-family:Verdana;">H NMR were used to investigate the selectivity of the thiourea monomer for phosphate over competing anions such as chloride and sulfate.

目前临床使用的非甾体消炎药(NSAI)除了镇痛、退热和消炎,还能阻断环氧合酶(co)而抑制内原性前列腺素(pG)合成,由此引起对胃肠道的刺激。不过,pG与炎症过程的关系及其如何控制炎症等问题尚待解决。在近几年中,已报道了一类与经典的非甾体消炎药(NSAI)十分不同的消炎药。该类化合物作用于花生四烯酸的级联代谢(cascade metabolism),有些对该酸的两条代谢途径都有影响,有些则对这些内原性介质无甚影响。本文将对非经典的NSAI包括最近发

就能源使用和碳足迹来说,炼铁和炼钢这类初级加工过程往往引起人们的极大关注。而轧制工序,虽然对能源需求很大,但钢铁企业在考虑自身的环境责任和节能机会时,却往往会将其忽略。初级加工过程相比于成品加工过程,能耗高,而且具有重要的影响。绿色轧制的关键主要在于收得率(和避免废品重熔),它就像能源的直接利用一样重要。以意大利阿维迪的全无头带钢生产(ESp)厂的设计和调试项目为案例,介绍现代化轧机如何为绿色钢铁工业做贡献。技术的有关特点包括近终形连铸和直接轧制及取消中间加热所带来的节能效果,传动和能量转换技术的进步,通过收得率最大化而实现节能的方案。还介绍了一些以绿色轧制为宗旨的重要的合作,包括与大学的合作,特别是剑桥大学的WellMet2050项目。作为结论,归纳了一般工业中使用钢铁的绿色原则,为设计打开重要思路。

In terms of energy use and carbon footprint,it is the primary processes of ironmaking and steelmaking that command most attention in our *** rolling mills,although energy-intensive by comparison with most industrial finishing operations,are often overlooked when a steel company considers its environmental responsibilities and its energy-saving opportunities. The high gearing of energy consumption of the primary processes over the finishing processes has an important consequence,*** key to green rolling is as much about yield(and avoiding the remelting of scrap) as it is about direct energy use. This paper uses a project case study,the design and commissioning of the Endless Strip processing(ESp) plant of Arvedi in Italy to illustrate how modern rolling mills are contributing to a greener steel *** relevant technical features include the energy savings implicit in near-net shape casting and in direct rolling,without intermediate reheating,advances in drive and power conversion technologies and the aforementioned concept of energy saving through yield maximisation. Some notable co.o.erative efforts towards greener rolling are also explained,including university collaborations and in particular the WellMet2050 project at the University of *** conclusion,the green credentials of steel usage in general industry are considered and key messages for the engineering community are sought.
