These nanostructures of 1D, such as nanowires, nanotubes and nanorods, present great potential for enhancing photon absorption, electron transit, and electron collection in solar cells. Graphene is a 2D hexagonal lattice of carbon atoms that is atomically thin. The remarkable mechanical properties of graphene are due to its structure, in which each carbon atom shares three of its four electrons in covalent bonds with its nearest neighbours (sp2 bonds). ...The remarkable mechanical properties of graphene are due to its structure, in which each carbon atom shares three of its four electrons in covalent bonds with its nearest neighbours (sp2 bonds). ...At the same time, the remaining fourth electrons are delocalized across the two-dimensional lattice in an orbital that accounts for the majority of the material’s optoelectronic capabilities. Also, Graphene is noted for having mobility that exceeds that of good metals. Furthermore, since a number of solution-based techniques, such as simple spin coating, may be used to create thin films of graphene a range of compositions can be created utilising low-cost, straightforward, and large-scale processes.

Abstract Using an ultrasonic-assisted stir casting method, a pure aluminum (Al) matrix (99% purity) was mixed with Graphene Nanoplatelets (GNPs) in various proportions ranging from 0.5 wt.% to 2.0 wt.% to create a Metal Matrix Composite. ...The microstructural and mechanical behavior of pure Al-graphene composites were studied experimentally, and it was discovered that Al with 1.0 wt.% graphene composite exhibits improved mechanical properties, with a 38.80% increase in tensile strength and a 56.07% increase in microhardness. ...According to the failure review, uniform graphene scattering in the parent matrix combined with negligible porosity resulted in a substantial improvement in mechanical properties, making it ideal for aerospace applications.

The present work, the effect of graphene and OMMT clay nano fillers in the conventional NBR/PVC (50: 50) composite with variation in filler weight fractions were studied for its mechanical properties. ...Results showed improvement in properties against the blank composite devoid of any fillers and increase in the weight fraction of graphene and OMMT clay has boosted the hardness and tensile strength of the base material. Influence of graphene had an upper hand in comparison with OMMT clay when it came for the hardness of the compound. ...Influence of graphene had an upper hand in comparison with OMMT clay when it came for the hardness of the compound.

Abstract The prediction of mechanical elastic response of laminated hybrid polymer composites with basic carbon nanostructure, that is carbon nanotubes and graphene, inclusions has gained importance in many advanced industries like aerospace and automotive. ...Further, the hybrid composite structures with graphene inclusions demonstrate better mechanical performance as compared to the identical structures with CNT inclusions.

The present study presents a detailed review of the machinability of AMMC (Pure Aluminum + Graphene nanoplatelets) using Wire Electric Discharge Machining (WEDM). For WEDM of AMMC, a multi-objective optimization method is proposed to evaluate possible machining parameters in order to achieve better machining efficiency.

This is the world's first report forecasting the global market for electric buses and taxis both hybrid and pure electric. It separately forecasts the market in the most important area, China, and it takes a detailed look at technologies present and future with a blunt assessment of reasons for failure and threats for the future. The market for electric buses and taxis will multiply over 8 times in the next decade, approaching $60 billion not long after that. China will become by far the largest market for both electric buses and electric taxis within the decade. This report looks at the statistics and trends for conventional buses and taxis, the government incentives, paybacks and new technologies with detailed tables and figures to summarize the situation, so the reader can understand the situation with ease.
