Gourisankar Roymahapatra, Ben Bin Xu, Chittaranjan Sinha
Acharya Sir Prafulla Chandra Rậy, a member of Companion of the Indian Empire (CIE, the Most Eminent Order of the Indian Empire founded by Queen Victoria), Founder Fellow of the Indian National Science Academy (FNI, Delhi which is now renamed as FNA), Fellow of the Royal Asiatic Society of Bengal (FRASB, Kolkata), Fellow of the Indian Association for the Cultivation of Science (FIAS, Kolkata), and Fellow of the Chemical Society (FCS, London), is a pathfinder and originator of India's modern chemistry – teaching and research, chemical industry, philanthropist, industrialist and educationist. He was born on August 2, 1861 in the village Raruli, Khulna, (now in Bangladesh). He learned science by attending as an external student, particularly chemistry from Prof. Alexander Peddler, Presidency College (now Presidency University, Kolkata). It was the only college, where science teaching started in pre-independent India. After receiving Gilchrist Scholarship, he joined the Edinburgh University UK in 1882 and received B. Sc. in Chemistry from Prof. Alexander Crum Brown in 1885 and D. Sc. in 1887. His research thesis entitled, "Conjugated Sulphates of the Copper-magnesium Group: A Study of Isomorphous Mixtures and Molecular Combinations" earned Hope Prize from the University. The double sulfates known in his times are a few only like Mohr’s salt (i.e., (NH4)2SO4,FeSO4·6H2O); cyanochroite, K2SO4, CuSO4·6H2O. Prafulla Chandra worked in the laboratory of organic chemist and the global research tempted to physical chemistry at that time. He found out more space in doubledouble sulphates, like Mm2SO4, MbSO4. 6H2O, Mm2SO4, MbSO4·6H2O (where Mm refers to monovalent; Mb or Mb refers to the bivalent metal ion). However, the structure of such salts was known much later, after the discovery of single crystal X-ray diffraction measurements in early 1930’s and the present form only appeared after 1960’s. Rây was elected as Vice-President of the University of Edinburgh Chemical Society in 1888 and the President was Prof. Alexander Crum Brown.

The distinctive morphology and novel properties of graphene is quite fascinating as a promising candidate for nanodevices. In this study, we annealed graphene oxide (GO) created through the conventional Hummers method at different temperatures, showcasing the simplicity, safety, and cost-effectiveness of thermal annealing as a superior large-scale fabrication approach. GO's capacity for post-thermal modification broadens its versatile applications in optoelectronics, electronics, nanoelectronics, and more. In this regard, this study investigates the optical, electrical properties, and chemical structure of GO after thermal reduction at temperatures 80°C, 120°C, 160°C, 200°C, 240°C, and 280°C under standard atmospheric pressure. According to the results of the Raman AFM map, the most obvious changes in thickness were observed at 280°C, where the average thickness of the reduced GO decreased by 50%. IR spectra indicated that the oxygen-containing functional groups are most stable up to 120°C and showed the loss of signals from hydroxyl groups at all other treatment temperatures. The values of the electrical sheet resistance after thermal reduction decreased from 2831.2 to 20.8 MΩ/square, which, in turn, affected the decrease in the interplanar distance from 7.12 Å to 3.80 Å. This work demonstrates a novel and effective strategy for fabricating high-performance, rGO films from local raw materials.

: The present review provides in-depth insights of the various lithographic processes that are currently being used in academic and industrial research labs for fabricating various micro-and nano-scale devices. All the patterning techniques discussed in this review have their own unique set of characteristics and use-case depending on the design requirement of the devices that need to be fabricated. This has tremendous implications in the electronic industry.
