Graphene, the amazing two-dimensional carbon nanomaterial, has attracted extensive interest in recent years and emerged as the most intensively studied material [1]. In 2004, Geim and Nosovelov at Manchester University successfully isolated single layer graphene by the mechanical cleavage of graphite crystal [2]. This ‘‘thinnest’’ known material exhibits extraordinary electronic, chemical, mechanical, thermal and optical properties which bestowed graphene as a miracle material of the 21st Century. From applicative perspectives, graphene holds a great promise with the potential to be used as energy-storage materials, in nanoelectronics, in catalysis, biomedical, in polymer composites and many more.
This document summarizes methods for synthesizing nitrogen-sulfur doped graphene for hydrogen storage. CVD (chemical vapor deposition) and the DVD burner method are proposed for graphene synthesis. CVD involves using a copper foil substrate, annealing in hydrogen and argon, and depositing using methane and hydrogen. The DVD burner method applies a graphite oxide and plastic film to a DVD, which is then inserted into a DVD drive to chemically reduce the graphite oxide to graphene using the laser. Nitrogen-sulfur doping of the graphene is achieved by heating dimethyl sulfoxide and sodium hydroxide under nitrogen gas flow to form a black cake-like material. These doped graphene materials show potential for efficient hydrogen storage.

This document summarizes research into reducing graphene oxide (GO) using lasers for applications in thin-film supercapacitors. The goal was to determine the optimized laser conditions for GO reduction. GO was deposited on glass slides in increasing layers and reduced using lasers at different wavelengths, powers, and through different microscope objectives. Raman spectroscopy and impedance measurements showed that a 633nm laser most effectively reduced GO over time, as evidenced by a decreasing ID/IG intensity ratio. The maximum capacitance of GO and reduced GO were measured through cyclic voltammetry and electrochemical impedance spectroscopy. The research demonstrated that lasers can effectively reduce GO for applications in flexible electronics and energy storage.

Today, in the industry of aluminum, the D. C. casting of billets and slabs is playing the major role. The producers of these slabs and billets are many. The end users of the product are OEMs. The degassing technology for producing these aluminum slabs and billets is provided by very few. There are two types of degassing methods currently in use. One of these, vacuum degassing, is used primarily in the steel industry and thus not generally used in the aluminum industry. The second method, generally employed in the aluminum industry, is rotary degassing, which uses finely dispersed argon, chlorine, fluorine to remove dissolved hydrogen and various salts from melt. The challenges associated with producing aluminum are reducing porosity due to hydrogen precipitation during casting through degassing processes; which generates detrimental effects on mechanical properties of alloy castings and removing impurities like; the Ca, Mg salts etc. from the molten metal. Looking at the degassing systems provided by these players, are going to be obsolete as the environment norms will become stricter in the next decade, because of the use of Fluorine and Chlorine for removing the Ca, Mg, etc. impurities from the molten metal as the ozone layer is getting depleted and process becomes more cumbersome and hazardous. So, the innovation in the technology is needed; which leads research interest on development of the ultrasonic degassing as a better option. During this research authors would be using ultrasonic technology over existing technology to compare the results of conventional degasser units available in the market such as LARSTM, SNIFTM, STASTM - ACDTM, AlpurTM, MDUTM etc., and would be finding out the better operating parameters of ultrasonic equipment for the process for replacement of Fluorine and Chlorine based old technology with Ultrasonic Technology. This research paper should underpin improvement in the process and hence improved hardness of material by elimination of the fluorine and chlorine usage by replacing it with ultrasonic technology with suitable mechanical design, metallurgical criteria and thermal analysis consideration. During the entire research and development authors had carried out various operations like Research on thermal and metallurgical behavior of the molten metal and alloys, Comparison of results achieved using ultrasonic technique over existing technique, Formulation of conclusion; making ultrasonic technique a proven technology, and Identifying the further scope of research and development. With the experiments carried out, authors found significant improvement in hardness of the material produced by ultrasonic degassing as compared with the hardness of material produced by conventional degassing.

Deposition and Analysis of Graphene Thin FilmsAndy Skippins
The document discusses different techniques for depositing graphene thin films, including chemical vapor deposition (CVD) and alternative lower-cost methods like drop-casting, Langmuir-Schaefer deposition, and scattering graphene nano-platelets. CVD produces the highest quality films but is more expensive, requiring high temperatures. The study found that drop-casting produced films with quality almost comparable to CVD and was the lowest-cost technique. Langmuir-Schaefer had issues with crystals forming on the surface and scattered nano-platelets produced an uneven film with agglomerations. Alternative lower-cost deposition methods could enable more widespread commercial applications of graphene.

Graphene was first isolated in 2004 and its potential applications were recognized early, leading to the 2010 Nobel Prize in Physics being awarded to its discoverers. While graphene has excellent thermal and mechanical properties and allows for high electron mobility, widespread commercial applications are still lacking. Large investments have been made in graphene research totaling over $2.4 billion but manufacturing costs remain high due to the energy-intensive production processes needed. While some graphene phones and touchscreens have begun limited production, traditional materials remain cheaper to use. Graphene's future prospects depend on reducing production costs and developing applications that leverage its unique properties and take advantage of its high frequencies for applications like transistors.
In 2004, researchers at the University of Manchester discovered graphene, a one-atom thick layer of carbon atoms. It is the thinnest material in the world and is extremely strong and conductive. Graphene has a wide variety of potential applications such as in batteries, solar cells, composites, and coatings due to its unique properties. However, mass production of high quality graphene remains challenging and prohibitively expensive, limiting its economic potential. Researchers continue working to overcome production obstacles in order to fully realize graphene's applications across many industries.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence
