Photovoltaic/thermal air collector has potential to execute electrical and thermal energy concurrently. This paper investigates carbon dioxide mitigation and enviroeconomic analysis on basis of overall, energy and exergy gain of semi-transparent PVT (SPVT), and opaque PVT (OPVT) arrays under natural convection in Bikaner, Rajasthan (India). The analysis has been carried out on an array configuration of opaque and semi-transparent arrays having 7 modules connected in series. Experimental work has been done in the month of September to December and comparison has been made on the basis of electrical and thermal gains. The results depict that average electrical, thermal and overall exergy gain of SPVT array is higher by 9.20%, 15.2% and 8.08% with respect to OPVT array. The CO2 mitigation for four months for semi-transparent array is higher by 0.67 tCO2 and 0.15 tCO2 as compared to OPVT array on the basis of overall thermal energy and overall exergy gain respectively. The environmental cost of SPVT array is higher by Rs. 710.53 and Rs. 160.50 than OPVT array for four months with respect to overall thermal energy and overall exergy gain.

Thin film deposition by using different nanomaterials has been an efficient and reliable way for enhancing the anti-corrosive property of the materials as well as strength improvement such as hardness, conductivity and wear resistance. Various materials have been taken as substrates like mild steel, magnesium, Aluminum, Copper, Tin, Carbon steel with thin film coatings of Zn–TiO 2 , Ce/Co, Zn-HA/TiO 2, CrN/TiN, Ni- Co have been sampled. These specimens have been studied for numerous properties like surface roughness, wear resistance, adhesion strength, microhardness, hydrophobicity etc. It has been found that the components like muffler, differential, engine chassis, exhaust system, gears do undergo corrosion due to several factors like climate change, oxidation, moisture content etc. The aim of the review has been to highlight the advances in the coatings providing anticorrosive properties to various metallic substrates used specially for mechanical and automobile industries.

CuO and Zn doped CuO nanoparticles (Zn-CuO NPs) with varying concentration i.e., Zn x Cu 1 − x O (where x = 0, 0.5, 1, and 1.5%) have been prepared via microwave assisted method. The spheroid structure of CuO NPs and the nanorod structure of Zn-CuO NPs have been determined using High Resolution Scanning Electron Microscopy (HR-SEM) analysis. Elemental analysis has been carried out using Energy Dispersive X-ray Analysis (EDAX). The particle size and surface area of CuO and Zn-CuO NPs have been confirmed by Brunauer–Emmett–Teller (BET) method. The antibacterial studies have been revealed that Zn (1.5%) -CuO NPs exhibited maximum zone of inhibition (19-29 mm) against the tested four bacterial strains. Zn-CuO NPs have been displayed robust action of antibacterial activity with minimum inhibitory concentration (MIC) of 0.09 µM against Campylobacter coli ( C. Coli ). DPPH and H 2 O 2 radical scavenging assay investigation have been revealed that the significant scavenging activity has showed by Zn (1.5%) -CuO. The in vitro cytotoxicity evaluation of synthesized material against human breast (MCF7) and human lung (A549) cancer cell lines have been demonstrated that Zn (1.5%) -CuO NPs exhibited better cytotoxic activity against MCF7 cell lines (97.5% cell death) than A549 cell lines (90% cell death).

In recent years, Cu-Zn-Al alloys are studied intensively due to their excellence in shape memory effect (SME), good mechanical properties, along with accessible production process and cost. Cu-Zn-Al Shape Memory Alloy easily form stabilization in martensite phase that leads to SME properties reduction, but can be minimized by applying alternative quenching methods. In this research, several quenching methods are proposed to minimize the phase stabilization of martensite. The Cu-28Zn-3Al alloy was produced by gravity casting and homogenized at 800 ℃ for 2h followed by air cooling. Furthermore, as-homogenized plate was betatized at 850 ℃ for 30 minutes and then subsequently quenched using three different methods: direct quench (DQ), up quench (UQ), and step quench (SQ). Morphology, phase transformation, hardness, and strain recovery characterization are examined using an optical microscope, SEM-EDS, XRD, DSC, Vickers, and bending tests. The results showed that the DQ and UQ samples consist of V-shape βˈ[M18R] martensite as a matrix and retained α[A1] as the second phase. The volume fraction ratio of βˈ[M18R]: α[A1] is (98.4:1.6) and (92.9:6.1) for DQ and UQ, respectively. However, the SQ sample did not indicate the presence of the martensite phase and did not show any recovery rate. Bending test showed that DQ and UQ had 27.2% and 36.3% of recovery rate, respectively.
