Myself Dr Manilal Murmu, a researcher in Chemical Sciences and a 1st Generation Educated and PhD. I started my journey of early education from PIDT Lokshala (an NGO, then NIOS Education Center, now Anandalaya Public School) Madhupur holding warm hands of my Grand Parent. After my matriculation from Subhash Public School Giridih, Jharkhand, I was moved to Visva-Bharati, a Central University founded by Noble Laureate Gurudev Rabindranath Tagore at Santiniketan, India for my higher studies starting from Higher Secondary (Pre-Degree) education to post-graduation (M.Sc.) along with professional teachers training (B.Ed.) financially aided by Department of Scheduled Tribe, Scheduled Caste, Minority and Backward Class Welfare, Jharkhand, India. I have completed my PhD (Science) in the faculty of Chemical Sciences from CSIR-Central Mechanical Engineering Research Institute (CMERI) Durgapur affiliated to Academy of Scientific and Innovative Research (AcSIR) Ghaziabad, India by availing fi

Abstract An ab initio density functional theory (DFT) calculation revealed the electronic properties of azomethine functionalised epoxy, namely, 4-((oxiran-2-yl)methoxy)-N-(4-(4-(4-((oxiran-2-yl)methoxy)benzylideneamino)phenoxy)benzylidene)benzenamine (DSBE) and amine based curing agent namely diethylenetriamine (DETA), triethylenetetraamine (TETA) and para-phenylenediamine (PPD) responsible for its adsorption on the mild steel surface. The frontiers molecular orbitals (FMOs) and the corresponding energies as well as global softness values revealed the reactive nature of the studied organic molecules. The probable trends of the chemical properties of different amine cured epoxy have been predicted. The insights of the adsorption of these organic molecules have been visualized through density functional tight binding calculation. It revealed that these organic molecules are able to adsorb onto targeted metal surface viz. Fe(110), FeO(110) and Fe2O3(110) plane through charge density sharing occurring at the molecule-iron layer interface. Thus, a complete theoretical insight analysis and modelled simulated adsorption study provided a clear picture regarding the adsorptions of the organic molecules onto metallic surfaces.

Abstract The hard nanocomposite coatings comprised of titanium, silicon, boron, and carbon (Ti-Si-B-C) and titanium, silicon, boron, carbon, and nitrogen (Ti-Si-B-C-N) were deposited on SS 304 substrate using magnetron sputtering technique. The tribological properties of these Ti-Si-B-C and Ti-Si-B-C-N coatings were explored with the variation of load (200–600 g) and thickness (3–25 µm) against high strength steel ball using a ball on a disc tribometer. The nanoindentation technique was used to investigate the wear tracks and its consequent effect on the mechanical behaviour of uncoated and coated films. The analyses of the phases, microstructure, states of valence, shift of electron, and elemental compositions of the coatings were carried out by HRTEM, FESEM, AFM, XPS, EDX, and Raman spectroscopy techniques, respectively. The 2D cross-sectional profiles and 3D topographies of the wear tracks were explored using a 3D profilometer. All these studies established that the 10 µm thick titanium-based sputtered nanocomposite coatings on SS 304 are efficient wear-resistant materials that showed excellent protection of the substrates from wear up till application of 500 g load. A good correlation between the composition, structure, properties, and processing of materials has been discussed based on the obtained wear behaviour. HIGHLIGHTS The multicomponent Ti-Si-B-C and Ti-Si-B-C-N films were deposited on SS 304 using the magnetron sputtering technique. The 10 µm thickness of Ti-Si-B-C and Ti-Si-B-C-N sputtered films on SS 304 showed excellent anti-wear performance. The specific wear rate of Ti-Si-B-C coated SS 304 (1.10 × 10−5 mm3/Nm) exhibited almost negligible in comparison to bare SS 304 (13.78 × 10−5 mm3/Nm). The average hardness and modulus values of the worn region of Ti-Si-B-C film were investigated at 23 and 320 GPa, respectively even after using a 600 g load. The roughness values on the worn region of uncoated surfaces are higher than on coated surfaces.

Abstract In the boundary lubrication regime, the addition of long as well as straight alkyl chain containing additive exhibit a serendipitous impact on protecting various metallic surfaces or machinery components from friction and subsequent wear. In quest of environment-friendly, proficient friction-reducing, surface protective and cost-effective lubricant additives; herein, two diazomethine functionalised long-chain consisting organic molecules, namely (3E)-N-((E)-2-(octadecylimino)ethylidene)octadecan-1-amine (ODE) and (3E)-N-((E)-2-(dodecylimino)ethylidene)dodecan-1-amine (DDE) were synthesized through a one-pot condensation reaction. The surface protective film-forming, as well as wear and friction reducing properties of these organic additives on steel balls within paraffin oil (PO), were thoroughly explored using a four-ball tester with variation in time, load and speed. The addition of these additives showed a remarkable reduction of coefficient of friction (COF) and wear amount in compared to the pure base oil. ODE exhibited better performance with a ∼62% reduction in COF and ∼23% reduction in wear amount for steels in contact. Electronic level analysis for elucidating the tribofilm formation capability of the additives was rationalized using computational approaches such as density functional theory (DFT) and Fukui indices. Additionally, the molecular dynamics (MD) simulation which is an efficient computational approach was used to explore the spontaneous adsorption insight of additives; and also radial distribution function (RDF) were analysed to impressively explore the molecular-level interactions and adsorption mechanism of the additives with the metal atoms. Thereby, the mechanism of surface adhesive tribofilm formation and its metal protection capability has been explained in a comprehensive manner. Highlights Diazomethine functionalised organic molecules were synthesized with a variation of aliphatic chain length. Long aliphatic chain containing ODE additive showed enhanced surface protective performances in paraffin oil exhibiting lower COF value in comparison to DDE. Possible formation of ODE-based efficient tribofilm in metal-solution interface which exhibits enhanced surface adsorption property on the metal surface. Substantial decrease in wear upon addition of ODE in the base oil, which was confirmed by FE-SEM and 3D surface profilometer study. MD simulation has been used to investigate the adsorption competence of ODE and DDE on the iron surface.
