1考虑多因素的页岩气吸附模型——以川东南五峰组—龙马溪组页岩为例显示文摘甲烷在页岩中的吸附同时受页岩本体物理性质和外部储存条件的综合影响,为了建立考虑多种因素影响的页岩气吸附模型,以川东南五峰组—龙马溪组页岩为例,开展了不同总有机碳含量(TOC含量)的页岩在多个不同温度、不同含水率下对甲烷的吸附实验,采用Langmuir吸附模型对吸附数据进行了拟合,分析了饱和吸附量及Langmuir压力分别与温度、TOC含量及含水率的定量关系,最终建立了考虑温度、压力、TOC含量及含水率综合影响的多因素页岩气吸附模型,并通过与实测吸附数据对比验证了该模型的准确性。结果表明:Langmuir模型能很好的拟合五峰组—龙马溪组页岩在不同特定条件下的吸附数据,拟合精度较高,决定系数R^(2)介于0.9728~0.9982。饱和吸附量与TOC含量呈正线性相关,与温度及含水率呈线性负相关。Langmuir压力与TOC含量呈线性负相关,与温度及含水率呈线性正相关。30℃下TOC含量为4.17%的页岩干样吸附量比TOC含量为2.95%的页岩干样吸附量高约39%。当温度由30℃增至80℃时,TOC含量为4.17%的页岩干样其饱和吸附量降低约30.6%。对于TOC含量为3.66%的含水页岩,当含水率由0增至4.2%时,30℃和60℃下页岩气的饱和吸附量分别降低了23.1%和11.4%。基于Langmuir模型建立的考虑多因素的吸附模型能准确的计算不同TOC含量、不同温度及不同含水情况下的页岩气吸附量。经与2组实测吸附数据对比验证,整个实验压力范围内的相对误差均小于6%,平均误差分别为3.67%和2.48%。经采用其他文献中不同物性的页岩吸附数据验证,表明多因素吸附模型对不同页岩有很好的适用性。李爱芬 韩文成 孙海 ASADULLAH Memon 2021煤炭学报2021,46,3:6
2Effects of viscous dissipation and slip velocity on two-dimensional and axisymmetric squeezing flow of Cu-water and Cu-kerosene nanofluids显示文摘Squeezing flow of nanofluids has been taken into account under the effects of viscous dissipation and velocity slip.Two types of base fluids are used to study the behavior of Copper nanoparticles between parallel plates.Nonlinear ordinary differential equations governing the flow are obtained by imposing similarity transformations on conservation laws.Resulting equations are solved by using an efficient analytical technique the variation of parameters method(VPM).Influences of nanoparticle concentration and different emerging parameters on flow profiles are presented graphically coupled with comprehensive discussions.A numerical solution is also sought for the sake of comparison.Effect of different parameters on skin friction coefficient and Nusselt number is also discussed.Umar Khan Naveed Ahmed Mir Asadullah Syed Tauseef Mohyud-din 2015Propulsion and Power Research2015,4,1:4
3Collaboration for success:the value of strategic collaborations for precision medicine and biomarker discovery显示文摘Precision medicine aims to provide the precise treatment for the patient with the right dose at the right point of time.Biomarkers(BM)are vital for the identification of patients who would benefit the most from individualized treatment.In addition,they help to enable the prediction of prognosis,the detection of early therapeutic and adverse effects,and may serve as surrogate endpoints in clinical trials.BM are becoming essential tools to increase productivity in drug discovery and impressively enhance the way medicine is practiced.However,the identification,sufficient validation and implementation of such BM are challenging.This process requires expertise from different areas and high resource investments.Collaborations of different partners may be helpful to overcome these challenges.In the past decade,collaborations between diagnostics and pharmaceutical companies as well as industrial–academic collaborations have been increasingly pursued.Moreover,public funding may offer support and open new opportunities to form such consortia.Herein we give an overview of the different types of collaborations,their opportunities and challenges,and describe experiences in forming strategic partnerships with other companies.Lilla Landeck Monika Lessl Joachim Reischl Andreas Busch Patricia Carrigan Matthias Gottwald Petra Reinke Khusru Asadullah 2016Advances in Precision Medicine2016,1,1:3

5Wearable multifunctional printed graphene sensors显示文摘The outstanding properties of graphene have initiated myriads of research and development;yet, its economic impact is hamperedby the difficulties encountered in production and practical application. Recently discovered laser-induced graphene is generated bya simple printing process on flexible and lightweight polyimide films. Exploiting the electrical features and mechanical pliability ofLIG on polyimide, we developed wearable resistive bending sensors that pave the way for many cost-effective measurementsystems. The versatile sensors we describe can be utilized in a wide range of configurations, including measurement of force,deflection, and curvature. The deflection induced by different forces and speeds is effectively sensed through a resistancemeasurement, exploiting the piezoresistance of the printed graphene electrodes. The LIG sensors possess an outstanding range forstrain measurements reaching >10% A double-sided electrode concept was developed by printing the same electrodes on bothsides of the film and employing difference measurements. This provided a large bidirectional bending response combined withtemperature compensation. Versatility in geometry and a simple fabrication process enable the detection of a wide range of flowspeeds, forces, and deflections. The sensor response can be easily tuned by geometrical parameters of the bending sensors and theLIG electrodes. As a wearable device, LIG bending sensors were used for tracking body movements. For underwater operation,PDMS-coated LIG bending sensors were integrated with ultra-low power aquatic tags and utilized in underwater animal speedmonitoring applications, and a recording of the surface current velocity on a coral reef in the Red Sea.Altynay Kaidarova Mohammed Asadullah Khan Marco Marengo Liam Swanepoel Alexander Przybysz Cobus Muller Andreas Fahlman Ulrich Buttner Nathan R.Geraldi Rory P.Wilson Carlos M.Duarte Jurgen Kosel 2019npj Flexible Electronics2019,3,1:2
6水/乙醇/正辛醇无表面活性剂微乳液的介电弛豫谱显示文摘无表面活性剂微乳液近年来受到人们极大关注,但人们对该类微乳液体系的了解还不够深入,在许多基础问题上仍存在较大争议,因此十分有必要利用不同的技术手段对该类体系开展研究。介电谱是表征微乳液体系的有效方法之一,但在无表面活性剂微乳液体系中的应用还鲜有报道。根据水/乙醇/正辛醇所组成的三元体系相图,选取了3条路径配制了不同相组成的微乳液样品,进而在40 Hz~110 MHz频率范围内测量了这些样品的介电谱。发现在1~10 kHz频率范围内出现了明显的介电弛豫现象,利用Cole-Cole公式对该介电弛豫行为进行了拟合解析,从而准确获取了表征该介电弛豫特征的介电参数。通过分析介电参数对微乳液样品的相组成的依存性,发现介电参数能够较为准确地区分该微乳液体系的不同微观相区,其结果与文献报道基本一致。对不同微观相区内介电参数随体系相组成的变化规律进行了分析和讨论,据此提出了不同相区内该弛豫可能的微观弛豫机制。结果表明,不同的微观相区中该弛豫的微观机制不同:在分子溶液相区,该弛豫来自于电极上双电层内离子的迁移或氢键形成的网络中离子的迁移;在水包油及双连续相区,该弛豫来自于水相中离子的跳跃迁移;而在油包水相区,该弛豫来自于分散水滴在油相中的转动极化。刘灿利 KHAN Asadullah Muhammad 陈震 2021应用化学2021,38,7:2

13Transformation of chlorine in NaCl-loaded Victorian brown coal during the gasification in steam显示文摘This study is to examine the changes in Cl volatilizations and chemical forms in NaCl-loaded Victorian brown coal during gasification in steam at 800 ℃ using Cl K-edge X-ray absorption near-edge structure(XANES) spectroscopy.The char samples were prepared in a novel one-stage fluidised-bed / fixed-bed quartz reactor at a fast heating rate.The samples were then collected and sealed in an argon-filled bag in order to minimise possible oxidation of char and Cl by air prior to analysis by XANES.Char-steam reactions were found to significantly affect the transformation of Cl,including the possible formation of chlorine-containing organic structures.On the other hand,volatile-char interactions during the gasification appeared to enhance the Cl retention and prevent the formation of organic chlorine compounds in chars.ZHANG Shu Mohammad Asadullah Rosalie Hocking LIN Jian-ying LI Chun-zhu 2012燃料化学学报2012,40,12:1
