Nano-composite is an innovative material having nano in which fillers dispersed in a matrix. Typ-ically, the structure is a matrix- filler combination, where the fillers like particles, fibers, or fragments are surrounded and bound together as discrete units by the matrix. The term nano-composite encompasses a wide range of materials right from three dimensional metal matrix composites to two dimensional lamellar composites. Therefore, the physical, chemical and biological properties of nano materials differ from the properties of individual atoms and molecules or bulk matter. The chalcogenide – graphene composites in glassy regime is the growing novel research topic in the area of composite material science. It is obvious to interpret such materials different physicochemical mechanism. The key objective of this research work to explore the internal physicochemical mechanism of the chalcogenide – graphene composites under the glassy regime. Including the prime chalcogen alloying element selenium amorphous atomic structure and their fullerene like bonding nature. By accommodating the essential properties of the stacked layers of bilayer graphene. The diffusion, compression and dispersion of the bilayer graphene in selenium rich ternary (X(1-x-y)-Y(x)- Z(y) + GF (bilayer graphene); X = Se, Y = Semimetal or metalloid, Z = None metal) alloys under the complex regime on and after thermal melting process are addressed. To synthesize the composite materials the well-known melt quenched method had adopted. More-over, to interpret the amorphous selenium (Se8) chains and rings molecular structures we had used vista software with an available CIF data file. While to show the armchair and zig-zag bonds with bilayer graphene structure the nanotube modeler simulation software has used. Outcomes of this study reveals the chalcogenide -graphene nano composite formation under a glassy regime changes the individual materials structural and other physical properties that is reflecting in different experimental evi-dences, therefore, the modified theoretical concepts for the different properties of such composite materials are interpreted in this study. The dispersion and diffusion of the high stiff graphene bonds in low dimension chalcogen rich alloys has been interpreted based on their quadric thermal expansion behaviour. In addition to this, a possible bond angle modification in the formation of X(1-x-y)-Y(x)- Z(y) + GF composites are also addressed. To interpret the distinct optical property behavior of the formed X(1-x-y)-Y(x)- Z(y) + GF composites and parent chalcogenide glassy alloys a schematic model of the energy levels is also addressed. To make a better understating on the formation mechanism such composites, the diffusion and deformation of high stiff graphene σ and π bonds in a low dimension chalcogenide alloy basic mechanism are discussed on basis of novel “thermonic energy tunneling effect” concept, which could result in quadratic the
纳米复合材料是一种将纳米填料分散在基体上的新型材料。典型的结构是基质-填料组合，其中填料如颗粒、纤维或碎片被基质包围并作为离散单元结合在一起。纳米复合材料涵盖了从三维金属基复合材料到二维片层复合材料的广泛范围。因此，纳米材料的物理、化学和生物特性不同于单个原子、分子或块状物质的特性。玻璃态硫系-石墨烯复合材料是近年来复合材料科学研究的一个新兴课题。很明显，这类材料有不同的物理化学机理。本研究的主要目的是探索硫族化物-石墨烯复合材料在玻璃态下的内部物理化学机制。包括原素元素硒的无定形原子结构及其类富勒烯键合性质。通过容纳双层石墨烯堆叠层的基本特性。富硒三元体系(X(1-x-y)-Y(X)-Z(y) + GF)中双层石墨烯的扩散、压缩和分散X = Se, Y =半金属或类金属，Z =无金属)合金在热熔过程中和之后的复杂制度。复合材料的合成采用了著名的熔体淬火法。此外，为了解释无定形硒(Se8)链和环的分子结构，我们使用了vista软件和可用的CIF数据文件。同时利用纳米管modeler仿真软件来显示具有双层石墨烯结构的扶手键和之字形键。本研究的结果揭示了玻璃态下硫系化物-石墨烯纳米复合材料的形成改变了单个材料的结构和其他物理性质，这些性质反映在不同的实验证据中，因此，本研究解释了这种复合材料不同性质的修正理论概念。基于二次热膨胀行为解释了低维富硫合金中高硬度石墨烯键的分散和扩散。除此之外，本文还讨论了形成X(1-x-y)-Y(X)-Z(y) + GF复合材料时可能的键角修饰。为了解释形成的X(1-x-y)-Y(X)-Z(y)+ GF复合材料和母硫系玻璃合金的独特光学性质行为，还讨论了能级的示意图模型。为了更好地理解这类复合材料的形成机理，基于“热能隧道效应”的新概念，讨论了低维硫系合金中高刚度石墨烯σ键和π键的扩散和变形的基本机理，从而导致石墨烯的二次热膨胀。此外，还从键角的改变和配位缺陷的影响两方面描述了复合材料结构单元的改变。采用外来合金元素的影响和蜂窝带结构中石墨烯层间的表面π等离子体共振的观点，讨论了这种复合材料中的能级抑制和附加亚能级的产生。因此，本研究描述了硫系-双层石墨烯复合材料在玻璃态下形成的各个基本方面。

The economic growth of any country depends on certain factors of which energy is a part and even prominent. The global economy has depended heavily on fossil fuels as the main source of reliable energy for so many decades. Their adverse long-term impact on society has led to a substantial increase in research activities both in industry and academia. Most of the research has been dominated by the development of green energy technologies and the expansion of such technologies in order to meet increasing future demands of energy. Prominent among the research drive is the development of fuel cells, whose driving force comes from hydrogen. This is because hydrogen is economical considering its relative abundance, low cost, yet high activity in production. Materials such as Pt, C, Fe, MoS2 have gained popularity in the production of hydrogen for use in fuel cell devices. The high efficiency of MoS2, amorphous or crystalline, in hydrogen evolution reactions (HER) depends on a suitable architecture that increases the exposure of its edge sites. Such architecture could be determined by the design of catalysts in terms of proportions of molybdenum and dopant ions, the composite structure between MoS2 and electrically conductive materials, synthesis temperature and the synthesis method. Therefore, a review is made on recent achievements for different nanoarchitectures of MoS2 as well as its composite structures for use as electro-catalysts in HER performance and future prospects.

Nano-composites comprised of a polymer matrix and various types of nanosized fillers have remained as one of the most important engineering materials and continue to draw great interest in the research community and industry. In particular, graphene based nano-composites with high thermal conductivity, excellent mechanical, electrical and optical properties, becomes important and promising filler for making the next generation, high performance composite materials. Automotive and off-highway machinery industry are extensively viewed as being the industry in which the highest volume of advanced composite materials such as graphene based nano-composites will be used in the future to produce lighter, stronger, more energy-efficient, and safe vehicles. Design, modeling, analyzing and methods for large-scale production of the graphene based nano-composites in automotive and off-highway machinery applications considering it’s mechanical, functional and interface properties between the graphene and polymer matrix under severe loading conditions is challenging, potentially due to nonlinear properties, joining of dissimilar materials and high demand of computations. While graphene based material strategies have been investigated and demonstrated to be effective for structural application in various industries includes electronics, electromechanical and energy systems, currently there is limited research highlighting the specific knowledge available for design engineers and researchers concerned with lightweight and stronger solutions by use of graphene based materials for automotive off-highway vehicle applications. The present review presents, an overview of the latest studies that utilize graphene-based nanomaterials and their composites in automotive and off-highway machinery applications. First, the paper describes the concept of traditional composites used in present engineering industries considering its advantages and limitations, then highlights the key benefits of using nanostructured carbon material, such as graphene through some recent studies available in the literature. Then depicts the various mechanisms of integrating graphene as polymer reinforcements within composite materials, which have been found based on the survey, and their related modeling, designing, and manufacturing capabilities suitable for automotive and off-highway machinery industry. Finally outlines the available experimental evidence for graphene based composites. In order to lay the groundwork for future work in this exciting area, the paper discusses close by several future prospects as well as the current challenges in this field.

At present, graphene is one of the most up-to-date materials and it can be applied for various energy conversion devices and sensor technology. In this review article, our main focus is to summarize the role of graphene and its modified surface leading to develop hybrid nanomaterials and its applications in fabrication of pesticide sensor. Graphene based materials demonstrate exclusive electrochemical and optical properties as well as compatibility to absorb a variety of bio-molecules through π-π stacking interaction and/or electrostatics interaction, which make them ideal material to be employed in sensor application. The role of graphene is very crucial in preparing different unique and desirable hybrid functional composites along with nanoparticles, redox mediators, conducting polymers etc. to improve the performance of the sensors. Therefore, they can be easily used as a suitable material applying in fabrication of electrochemical sensors/ biosensors for the detection of organophosphorous and carbamate pesticides. A number of most recent reported works were discussed in which graphene-based hybrid composites show high sensitivity, good catalytic activity, selectivity towards the determination of pesticide either enzymatically or nonenzymatically. The properties of graphene (exceptional charge transport, thermal, optical, mechanical, high surface area, large pore volume and size, an opened ordered structure) play an important role in pesticide detection.

In this review, the evolution of hydrogen in combined cell system of Photoelectrocatalytic and microbial fuel disused. Hydrogen is used as chemical fuel. Hydrogen is being produced through Photoelectrocatalytic method. The semiconductor material put into the water and irradiated with solar light after which the hydrogen produced by different steps and accumulated. Production of hydrogen also occur in microbial fuel cell system. These are electrochemical devices that initially used to treat the wastewater. But now this cell has entered into very interesting field of research which is Bioelectrochemical (BES). BES produces hydrogen using biomass as a catalyst using small consumption voltage rather than simple electrolysis of water. The first sections explain how hydrogen is produced individually by these two methods. And then we make comprehensive review on the evolution of hydrogen by combined microbial fuel and photoelectrocatalytic cell system, which is our main motive of writing this article. The continuous production of hydrogen by (PEC-MFC) hybrid device, using sunlight and splitting of water and electrohydrogenesis of microbial cell in fusion device (PEC-MFC) were also reported. This method gives continuous production of hydrogen using wastewater under solar light and also gives the treatment of wastewater. It is the clean energy source and also fulfills the today’s demand of energy. At last, a review on production of hydrogen by microbial photoelectrochemical system which is constructed by photocathode of semiconductor material and an anode of microbial. Production of hydrogen was continuously achieved without external voltage under ultraviolet irradiation.

This method gives continuous production of hydrogen using wastewater under solar light and also gives the treatment of wastewater. It is the clean energy source and also fulfills the today’s demand of energy. At last, a review on production of hydrogen by microbial photoelectrochemical system which is constructed by photocathode of semiconductor material and an anode of microbial. Production of hydrogen was continuously achieved without external voltage under ultraviolet irradiation.\u0000","PeriodicalId":294135,"journal":{"name":"Current Graphene Science","volume":"10 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132596489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Energy is a fundamental aspect in human life. It acts as blood for humans. No energy means no facility and frozen life activities. It needs for agricultural, economics and in domestic level etc. demands of energy is increasing day by day as increases population especially in developing countries. To meet energy requirement renewable energy is more efficient; no greenhouse effect, no emission of CO2, create least amount of resultant wastes, are sustainable base lying on existing and prospect financial and societal desire, no pollution and a safe environment to breathe freely. Mostly renewable energy comes as of ordinary source the same as wind energy, lunar and stellar energy, Bioenergy and hydropower energy etc.
