The utilization of the greenhouse gas CO2 in energy-storage systems is highly desirable. It now shown that introduction graphene as a cathode material significantly improves performance Li-CO2 batteries. Such batteries display superior discharge capacity and enhanced cycle stability. Therefore, can act an efficient batteries, it provides novel approach for simultaneously capturing storing energy.
Lithium–oxygen batteries are attracting more and interest; however, their poor rechargeability low efficiency remain critical barriers to practical applications. Herein, hierarchical carbon–nitrogen architectures with both macrochannels mesopores prepared through an economical environmentally benign sol–gel route, which show high electrocatalytic activity stable cyclability over 160 cycles as cathodes for Li–O 2 batteries. Such good performance owes the coexistence of in C–N architectures,...
3D hierarchical porous N-rich graphitic carbon materials were prepared and further used for symmetric aqueous supercapacitors with battery-level energy density while retaining capacitor-type power cycling stability.
In this work, we present a facile sol–gel method to prepare composite of Co nanoparticles highly dispersed on N-rich carbon substrates (Co–C composite). The assembled Li–O2 batteries with the as cathode catalyst showed lower overpotential and better cyclability, improved performance may be attributed superior electrocatalytic activity Co–C composite.
Escalating threat of global warming and the steady growth in world population require development transformative greenhouse gas control technologies food production systems high energy efficiency, small environmental footprint low cost. To temperature rise below 2 °C by 2050, emissions need to be cut more than 80%. At same time, our land needs utilized efficiently productively order produce enough feed projected 9 billion people with less available area for 2050. We propose develop a modern...

The need for electrically insulating materials with a high in-plane thermal conductivity lateral heat spreading applications in electronic devices has intensified studies of layered hexagonal boron nitride (h-BN) films. Due to its physicochemical properties, h-BN can be utilised power dissipating such as an spreader material laterally redistributing the from hotspots caused by locally excessive flux densities. In this study, two types based test structures have been assembled and evaluated...
