Improved dielectric and electro-optical parameters of nematic liquid crystal doped with magnetic nanoparticles

引用

Chinese Physics B 2019年第3期28卷 223-229页

作者： Geeta Yadav Govind Pathak Kaushlendra Agrahari Mahendra Kumar Mohd sajid Khan V S Chandel Rajiv Manohar Liquid Crystal Research Laboratory Department of PhysicsUniversity of LucknowLucknow 226007India

This study investigates the effect of magnetic nanoparticles(NPs) on the weakly polar nematic liquid crystal(NLC).Different parameters of dielectric data were measured for both the homeotropic and planar aligned samples as a function of frequency and temperature and the substantial changes have been noticed for the doped systems. Dielectric permittivity has been increased after the dispersion of magnetic NPs in the pure NLC. Dielectric anisotropy has also been influenced by incorporating the magnetic NPs with the NLC molecules. These results were attributed to the dipole–dipole interaction between the magnetic nanoparticles and nematic liquid crystal molecules. Electro-optical study indicated the faster rise time and fall time of the doped systems as compare to pure NLC. Threshold voltage has been calculated and found to be decreased for the doped systems. Moreover, we have also calculated the rotational viscosity and the splay elastic constant for pure and the doped systems. Both the rotational viscosity and splay elastic constant of the doped systems are found to be considerably lower than those of pure NLC. Change in these properties has been explained on the basis of molecular disturbances created by the interaction between the magnetic nanoparticle and LC director. This study reveals that the inclusion of magnetic NPs in weakly polar NLC can be useful to enhance the basic properties of the weakly polar NLC and make it a promising material for many display applications.

Estimation of Solar Energy Potential from Rooftop of Punjab Government Servants Cooperative Housing Society Lahore Using GIS

引用

Smart Grid and Renewable Energy 2015年第5期6卷 128-139页

作者： muhammad Luqman sajid Rashid Ahmad Samiullah Khan Usman Ahmad Ahmad Raza Farkhanda Akmal Institute of Geology University of the Punjab Lahore Pakistan

Pakistan has a severe electricity load shading problem. Government is trying to find out all ways for electricity generation. Alternative energy board is working to find out the energy potential using all alternative resources. Board has an objective to produce 9700 MW by 2030 to overcome load shading problem. A research was designed to find out the solar energy potential as an alternative source of energy from rooftops of residential areas in district Lahore. Punjab Governments servants housing society Lahore is selected. The society has minimum slope, aspect and shadows effects on the roofs. Also houses in PGSHS have same house structures and good town plan. A few portions of roofs are digitized to measure the available rooftop area for Photovoltaic panel’s installation. GIS models are used to find out solar energy potential monthly as well as yearly for the year of 2014. The potential estimated is 39,613,072 kWh/year. The monthly total energy consumption of the society is 347,140 kWh which is only 11% of energy production from PV solar panels. As the estimated energy is 9 times than the energy demand of the society, extra energy can be used in local/national electricity transmission grid. Solar PV energy would be supplement to compensate energy shortfall in local area.

Recent advances in gel polymer electrolyte for high-performance lithium batteries

Journal of Energy Chemistry 2019年第10期28卷 126-142页

作者： Ming Zhu Jiaxin Wu Yue Wang Mingming Song Lei Long sajid Hussain Siyal Xiaoping Yang Gang Sui State Key Laboratory of Organic-Inorganic Composites College of Materials Science and Engineering Beijing University of Chemical Technology

Lithium batteries (LBs) have become increasingly important energy storage systems in our daily life. However, their practical applications are still severely plagued by the safety issues from liquid electrolyte, especially when the batteries are exposed to mechanical, thermal, or electrical abuse conditions. Gel polymer electrolytes (GPEs) are being considered as an effective solution to replace currently available organic liquid electrolyte for building safer LBs. This review provides recent advancements in GPEs applied for high-performance LBs. On the one hand, from the environmental and economic point of view, the skeletons of GPEs changed from traditional polymer to renewable and degradable polymer. On the other hand, in addition to being as a component with good electrochemical and physical characterizations, the GPEs also need to provide some functions for addressing the concerns of lithium (Li) dendrites, unstable cathode electrolyte interface, dissolution and migration of transition metal ions,"shuttle effect" of polysulfides, and so on. Finally, to synchronously meet the challenges from the advanced cathode and Li metal anode, the bio-based GPEs with multi-functionality are proposed to develop high-energy/powerdensity batteries in the future.

BACKGROUND We previously reported national 30-d readmission rates of 27% in patients with decompensated cirrhosis(DC).AIM To study prospective interventions to reduce early readmissions in DC at our tertiary *** Adults with DC admitted July 2019 to December 2020 were enrolled and randomized into the intervention(INT) or standard of care(SOC) arms. Weekly phone calls for a month were completed. In the INT arm, case managers ensured outpatient follow-up, paracentesis, and medication compliance. Thirty-day readmission rates and reasons were *** Calculated sample size was not achieved due to coronavirus disease 2019;240 patients were randomized into INT and SOC arms. 30-d readmission rate was 33.75%, 35.83% in the INT vs 31.67% in the SOC arm(P = 0.59). The top reason for 30-d readmission was hepatic encephalopathy(HE, 32.10%). There was a lower rate of 30-d readmissions for HE in the INT(21%) vs SOC arm(45%, P = 0.03). There were fewer 30-d readmissions in patients who attended early outpatient follow-up(n = 17, 23.61% vs n = 55, 76.39%, P = 0.04).CONCLUSION Our 30-d readmission rate was higher than the national rate but reduced by interventions in patients with DC with HE and early outpatient follow-up. Development of interventions to reduce early readmission in patients with DC is needed.
