In the urban atmosphere of bengaluru, various volatile organic compounds(VOCs), particularly benzene,Toluene, Ethylbenzene, and Xylene(bTEX), have shown an increasing trend in concentration. The present research was conducted during summer and monsoon seasons, focusing on Kadubeesanahalli, a high-traffic area within the bengaluru metropolitan City. Hourly sample data was collected using a bTEX analyzer(model GC955-600) and subsequently transformed into daily, monthly, and seasonal values. The study revealed distinct patterns in benzene concentrations. benzene levels were lowest during the early morning hours, specifically from 1:00 *** 7:00 a.m.. Concentrations then increased from 7:00 a.m. to 9:00 a.m. and again from 4:00 p.m. to 11:00 p.m.,corresponding to the morning and evening peak traffic hours. However, between 10:00 a.m. and 4:00 p.m., the concentration decreased due to reduced traffic levels. These diurnal variations in benzene concentration are influenced by meteorological parameters. Comparing the two seasons, higher concentrations of benzene, Ethylbenzene, and mP-xylene were observed during the summer season. This increase is attributed to the elevated temperatures during summer, which promote the vaporization of bTEX compounds. Conversely, lower bTEX concentrations were recorded during the monsoon season due to the wet deposition process. The observed positive correlation(r > 0.5) among bTEX parameters strongly suggests a common source, most likely originating from vehicular emissions.

研究激光粉末床熔融增材制造(Am)(又称直接金属激光烧结)技术制备的Ti6Al4V合金等离子体电解氧化(PEO)处理及其电化学行为。通过短时间(m合金和传统合金表面制备了3~10μm厚、含Ca和P的涂层。然后在改良的α-mEm溶液中,通过动电位极化曲线和电化学阻抗谱(EIS)评估了合金的电化学行为。与传统合金相比,Am合金中形成了细小的层片状α显微组织和层间小尺寸的β相颗粒,这促使了火花的产生,从而促进了PEO涂层的生长。闪速PEO涂层提高了传统合金和Am合金的耐腐蚀性,最薄的涂层(m)提供了高达3倍的保护。Am Ti6Al4V由于其高的晶界密度,易受局部缝隙腐蚀的影响。而即使短至35 s的闪速PEO处理也足以成功避免这种情况。
