建立同时快速测定化妆品中7种双酚类化合物及其衍生物的超高效液相色谱–串联质谱方法.水剂化妆品采用正己烷–乙酸乙酯(体积比为1:1)溶液超声提取;粉类、膏霜乳液类、凝胶类化妆品采用乙酸乙酯超声提取,提取液经氮吹浓缩后用甲醇–水(体积比为1:1)溶液定容,用Waters XSelect HSS T3(100 mm×2.1μm,1.7μm)色谱柱分离,采用质谱多反应监测模式检测,色谱峰面积外标法定量.7种双酚类化合物及其衍生物的质量浓度在0.1~50.0 ng/mL范围内与色谱峰面积线性关系良好,相关系数均不小
Machine learning potentials are promising in atomistic sim-ulations due to their compara-ble accuracy to first-principles theory but much lower com-putational cost.However,the reliability,speed,and trans-ferability of atomistic machine learning potentials
Influenza A (A/HxNy) is a signif-icant public health concern due to its high infectiousness and mortality.Neuraminidase,which interacts with sialic acid (SIA) in host cells,has become an essen-tial target since its highly con-served catalytic center struc
In the past few years,the renormalized excitonic model (REM) approach was developed as an efficient low-scaling ab initio excited state method,which assumes the low-lying excited states of the whole system are a linear com-bination of various single monom
分析对比气相色谱–串联质谱(GC–MS/MS)法测定中药材中35种农药残留的3种样品处理方法,为中药材中农药残留检测提供参考.以乙腈为提取溶剂,样品经高速匀浆提取后,取提取液进行净化处理.比较了基于QuEChERS原则的处理方法、石墨化碳黑–氨基复合固相萃取(GCB–NH2)法和亲水亲油平衡材料固相萃取(HLB)法3种净化方式对中药材中35种农药残留检测的基质效应、色谱峰干扰、回收率等方面的影响.基于QuEChERS原则的处理方法回收率最好,除杀虫脒外其它34种农药回收率均为72.9%~110.9%,但净
建立内标校正气相色谱–质谱法测定空气PM2.5中邻苯二甲酸二(2-乙基己基)酯(DEHP)的不确定度评定方法,分析影响测量结果不确定度的因素,为提高检测结果质量提供依据.依据JJF 1059.1—2012《测量不确定度评定与表示》,建立数学模型,分析不确定度来源,评定各不确定度分量,计算合成标准不确定度和扩展不确定度.空气PM2.5中DEHP的质量浓度为(0.306±0.020)μg/m3,k=2.测定结果的不确定度主要来源于采样体积、提取液测定和测量重复性,其中提取液测定引入的不确定度分量最大,采样体积
Ring polymer molecular dynam-ics (RPMD) calculations for the C(1D)+H2 reaction are performed on the Zhang-Ma-Bian ab initio po-tential energy surfaces (PESs) re-cently constructed by our group,which are unique in very good de-scriptions of the regions aro
In this work,we studied the elec-tronic band structure of the halogen (F,Cl,and Br) functionalized graphdiynes(GDYs) by using hybrid density func-tional theory.The results revealed that the bandgap energies of modified GDYs increase as the number of halog
In this work,we explore the suitabil-ity of several density functionals with the generalized gradient approxima-tion (GGA) and beyond for describ-ing the dissociative chemisorption of methane on the reconstructed Pt (110)-(2×1) surface.The bulk and surfac
Antifreeze glycoproteins(AFGPs) facilitate the survival of various organ-isms in the polar region by preventing internal ice accumulation via an adsorption-inhibition mechanism.Inhibition of AFGP antifreeze activity by the borate buffers has been widely a
