Investigations were made into the fatigue in the magnesium alloy AZ 91C cast in corrosive fluids and air at varied NaCl solution concentrations. Fatigue specimens will be subjected to surface stress testing in corrosive conditions with a stress amplitude of 75 MPa both after and before coating. To comprehend the behavior of the magnesium material, its fatigue life, corrosion product (X-ray spectra), and fracture properties will be examined. The corroding medium (NaCl) has been found to significantly shorten the fatigue life of the magnesium alloy AZ91C. Chemical conversion treatment was applied to the AZ91C alloy to improve corrosion resistance and corrosion fatigue resistance. MgSnO3 was found in the XRD patterns of the stannite-treated AZ91C alloy, and this treatment slightly improved the alloy's corrosion resistance in an alkaline stannite solution with a pH of 7. H2O and SEM images demonstrate that chloride ions can penetrate the substrate through porous structures.

Nano Insulation is a liquid-consistency, colourable, paint-like thermal insulation material with many other beneficial properties in addition to insulation. It is a material that can be used both indoors and outdoors in industrial, civil and other types of constructions. Compared to conventional insulation materials, this photocatalytic system is beneficial for internal and external air purification and uses nanotechnology with Titanium Dioxide effective for preventing viruses, bacteria, cleaning polluted air from toxins, removing odours, stopping moulds and fungi, purifying water and more benefits. Among the essential features we list: Heat reflection by at least 60-70%, which reduces heat costs by at least 30%; Reduces the noise level by 0.6 mm up to 2 dB; its composition does not contain harmful or poisonous components; protects the coated surface against weather conditions and corrosion; retains its properties in extreme conditions for a long time; it has a lifespan of over 10 years; with implementation guarantee; with a side cover, the quality of incoming cold air is reduced by at least 30%, with both sides covered by at least 55%; 78% water absorption and high vapour permeability are excellent for the interior comfort; is non-combustible: does not fuel the combustion, helps to slow down the speed of the flame; simple and quick use with a sprayer.

In this study Neem and Yellow oleander biodiesels were blended in some given proportions and characterized. An F165 diesel engine was ran with each blend and its performance parameters evaluated and compared to those obtained when the engine ran on Automotive Gas Oil (AGO). The produced neem oil biodiesel (NOB) and yellow Oleander biodiesel (YOB) were blended together in a percentage ratio of 20:80, 40:60, 60:40 and 50:50 percentages for Neem and Yellow oleander biodiesels respectively. Results show that brake power of the blends is close to that of AGO at lower torques but developed higher power at higher torques (2.69 kWh at 10Nm for N10Y40 and 2.68 kWh for AGO). The blends exhibited close comparison with the AGO in thermal efficiency. The results of the study show a diesel engine perform well with pure biodiesel blends as fuels as it does with fossil AGO, thus new biofuel was produced capable of replacing conventional diesel fuel in the transportation industry.

Diabetes Mellitus, or Diabetes in short, is a group of widespread endocrine diseases characterized by high blood sugar levels. This research paper attempts to find a solution to this high sugar problem, by taking the route of electrochemistry. It was attempted to demonstrate that the excess sugar (glucose) in the bloodstream of a diabetic patient can be lowered by electro-oxidizing the excess sugar in Simulated Body Fluid (SBF) and convert it into electrical energy. For this, a sugar level detection system was developed, using a linear regression model with a coefficient of determination (R2 value) of 0.974. At first, one of the most popular as well as costly electrocatalytic materials i.e., Platinum was used to electro-oxidize the excess sugar. Upon its success, some highly electrocatalytic but cheap electrode materials were developed, such as Nickel, Nickel with nanocarbon, Manganese dioxide (MnO2) and Manganese dioxide with nanocarbon (MnO2C). And they also successfully electro-oxidized the excess glucose in SBF solution, thereby reducing the sugar levels. Thus, a potentially novel route to deal with the epidemic problem of diabetes has been proposed through this research work.

Metals were used to make artifacts and medical tools in ancient times. This review article focuses on the gold and silver metal artifacts of the ancient Egyptian and their protection against corrosion. There is no doubt that Egypt is an open museum because the ancient Egyptians planted the monuments everywhere in the deserts. There are many types of artifacts, such as statues, jewelries, furniture, weapons, paints, etc. They have used different types of materials to make all these monuments, such as marbles, wood, stones, metals. They have used different types of metals, such as gold, silver, iron, and copper. The museums in Egypt accommodate huge number of metals artifacts. Ancient Egyptian produced fine and gorgeous artifacts, especially rings, bracelets, and necklaces. The artifacts were created to be resistant to degradation and corrosion over a long period of time. They have used different ways of protection, such as paints, alloying, chemicals etc.

Titanium alloys have long been esteemed for their exceptional mechanical properties and biocompatibility, making them a cornerstone material in various biomedical applications. However, to harness their full potential in implantology, orthopedics, and dentistry, biofunctionalization plays a pivotal role. This article provides a comprehensive exploration of the techniques and applications involved in biofunctionalizing titanium alloys.

This research addresses the metallurgical and mechanical response during the annealing of Ti6Al4V parts fabricated by selective laser melting. The as-manufactured Ti6Al4V exhibited a very fine α´ martensitic structure with low ductility of less than 10%. It was observed that the fine α´ martensitic structure transformed into two phases of α and β by applying heat treatments at 850 and 1020 °C followed by furnace cooling. The experimental results demonstrated that 850°C/2h/FC heat treatment has optimum mechanical performance in terms of tensile strength and ductility.

Using the simple Chemical Bath Deposition (CBD) method, Cu-doped thin films of zinc sulfide (ZnS) were deposited on glass substrates in a concentration range of 0.05-0.1% Cu. These films were made to be used as a buffer or window layer in solar cells. Different deposition conditions were investigated to find the optimal growth conditions; after that, the conditions were deployed to deposit the required films. XRD graphs confirmed a hexagonal structure, and SEM images indicated that the incorporation of Cu stabilises small grain growth in the films. The appearance of the sample surface was dense, with an ordered granular shape, and free of any cracks. The optical and surface properties of the prepared films have been analysed using state-of-the-art instruments. The effect of pH on such properties has also been investigated. The transmittances of the films were about 20–85%, and the incident wavelength range was 300–1100 nm. The transmission line shows a sharply increasing tendency. After that, it increases slowly and goes to a stable state above 400 nm. A film of pH 10.0 showed a high transmission coefficient (85%). Also, the absorbance of the ZnS thin films rapidly decreases up to 360 nm. After that, it decreases slowly and becomes stable above 400 nm. The band gap is in the range of 3.58–3.62 eV, which indicates that it absorbed the UV portion of the electromagnetic wave and could be used as the UV filter.

Used Li-ion batteries through recycling allow the recovery of deficient and expensive elements such as cobalt, nickel and lithium. The work presents the possibilities of recovering cobalt from the cathodic paste of worn Li-ion batteries. The method applied for the recovery of cathode paste is the one with ultrasonication in acidic medium. Citric acid was used as a fainting medium. The method is viable and environmentally friendly. The cathode paste obtained by processing in the oven mixed with alumina leads to the obtaining of a blue cobalt pigment.
