Graphene was discovered in 2004 and has potential applications in electronics, optics, energy storage, and other areas. It was awarded the Nobel Prize in 2010. While graphene shows promising properties, limitations remain in reproducible large-scale production and its ability to be used as a transistor.

Graphene Prospects and Applications
Almost everything surrounding us is made up of carbon based materials, of them, one of the most important material is possibly graphene. It is a 2D crystalline form of carbon, one atom thick. It has garnered immense interest in the field of material sciences due to its unique set of physical, electrical, thermal, and mechanical properties. This has set it up as a major alternative to many of the conventional materials in a wide variety of fields. This paper discusses some of the uses and applications of graphene, along with techniques employed for its synthesis and some of the most promising prospects of this wonder material.

Nanotechnology
Nanotechnology has applications in electronics by enabling the creation of devices at the nanoscale. It allows building things atom by atom to create tiny machines called nanomachines. Working at the nanoscale allows controlling materials' properties and creating new functional materials. This leads to applications like carbon nanotube transistors that have higher electron mobility than silicon transistors. Carbon nanomaterials like nanotubes and graphene are also used to create highly sensitive nanosensors due to their large surface area and electrical properties.

This document provides an overview of graphene presented in a seminar by Hitesh D. Parmar. It discusses the history, structure, production methods, properties and applications of graphene. Key points include that graphene is a single atom thick layer of graphite, first isolated in 2004. It has exceptional electrical, thermal and mechanical properties. Common production methods are micromechanical cleavage, chemical reduction of graphene oxide and growth on metal substrates. Graphene has applications in electronics, energy storage, composites and water filtration due to its unique properties.
Review paper (PPT) on Graphene.pptx
The document presents a literature review and study on graphene and its composite materials. It summarizes several past studies on graphene discovery and properties. The objective is to study graphene and its composites. Literature on graphene's unique mechanical, electrical, thermal and optical properties are reviewed. Methods of producing graphene and graphene composites with polyurethane and Kevlar are described. Simulations show graphene composites can absorb 32% more energy than polyurethane alone. Applications discussed include use in batteries, solar cells, bulletproof vests, and as a transparent protective material. The conclusion is that graphene composites will be widely used in electronics, armor, and other fields due to graphene's strength and properties.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.

Adaptive synchronous sliding control for a robot manipulator based on neural ...
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.
