Direct radiative forcing of Black carbon is one of uncertainty for climate change.In order to assess the aging of BC particles under ambient conditions in terms of the enhancement of mass absorption cross-section(MAC),the measurements conducted by using a novel quasi-atmospheric aerosol evolution study(QUALITY)chamber under polluted conditions in Beijing,China.

In recent years,two-dimensional nanomaterials have garnered widespread attention for its important theoretical value and broad prospects of application.
One special feature of the heterobimetallic phosphido-bridged complexes is the influence of the metal-metal bond on the reaction [1].
We present new massively parallel implementations of linear-scaling PNO-LMP2-F12 [1] and PNO-LCCSD-F12 methods.
Solar energy conversion materials have sprung up in last decades as the key to confront the crisis caused by the depletion of fossil fuel and the excessive emissions of CO2.
B3LYP is currently the most widely used density functional approximation,while the X1 family of methods [1-8],namely X1,X1s and X1se,is a set of neural network based methods that systematically correc
Aromaticity,one of the fascinating topics in chemistry,has attracted considerable attention from both experimental and theoretical chemists for many decades.
全氟辛酸(Pentadecafluorooctanoic acid,PFOA)是一类新型的持久性有机污染物,具有生物累积性、持久性、毒性及长距离迁移能力.1951～2004年期间,全球产生PFOA的总量约为3600～5700t,约400～700t被排入环境中[1].到目前为止,它已经被发现在废水、地表水、地下水、甚至自来水中[2].
本文分析了MOUDI样品的水溶性无机离子的模态分布,并利用E-AIM和PMF模型模拟了不同季节液滴模硝酸盐的形成机理.结果表明,PM1.8中的SNA离子主要来源于液滴模,在春夏秋冬四季,液滴模中的SNA分别占PM1.8中的61 ％、48 ％、66 ％和80 ％.
全氟辛烷磺酸(Perfluorooctane Sulfonate,PFOS）以其优良的热稳定性,高表面活性,化学稳定性及疏水疏油性能.被广泛应用在诸多领域.PFOS作为一种新型的有机污染物存在于环境介质乃至生物体的血液及肝脏中.
