Article 3: Influence Of Coating Thickness On The Formability Of Annealed Aluminum 2024

The third article of the issue is authored by Irfan Mahmood Khan et al., from Université De Montpellier, France, and Institute Of Space Technology, Pakistan. This article talks about the sheet metal forming of uncoated Aluminum 2024 (Al-2024-TO) alloy. Here, four sets of coated specimens (CS) with different film thicknesses (5 μm, 10 μm, 15 μm, and 20 μm) were anodized and formed to study the effect of coating thickness and lubricant entrapment on the formed depth. Characterization of coated specimens exhibited that the porous thin film with an optimum thickness of 10 μm facilitated the maximum entrapment of lubricant in the pores. The result demonstrates that the enhanced lubrication for CS-2 resulted in the aggravated material flow which showed minimum hardness (60 HV), minimum thickness variation (2.82-2.90 mm), and minimum draw force (11 kN) with the maximum draw depth of 172 mm.

Article 4: Nonwovens With And Without Super-Absorbents Surface Help Firefighters As Additional Active-Cooling To Prevent Heat-Related Deaths

The fourth article of the issue is authored by Sebastian Micus, et al., from German Institute for Textile and Fiber Research Denkendorf, (DITF) and University Of Stuttgart, Germany. The study discussed in the article focused on drawbacks of the Personal Protective Equipment (PPE). In the article, the author described that in case of fire, fighter’s protection has insufficient dissipation of heat and sweat, and as a result, the body temperature increases. Further, at DITF, intensive research is being conducted on cooling materials to protect firefighters from heat. The author described the development of the active water cooling textile, consisting of different layer constructions and absorption materials. They used super absorbents polymer fleeces and natural viscos fleeces with different weights. The result demonstrates that special thermos-physiological measurement system has been used to measure the cooling ability of the different layer constructions. Moreover, possible cooling effects have be calculated in the article.

Article 5: Enhanced Electrochemical Reduction of CO2 By Zeolitic Imidazolate Frameworks-8 Supported Silver Nanoparticles

The fifth article is reported by Zhihong Zhuang et al., from Zhejiang University, People's Republic of China. This article describes that ZIF-8 supported thiol-capped Ag nanoparticles (Ag NPs) is can be act as a typical catalyst for CO2 electroreduction and to improve the CO faradaic efficiency. The synthesis of the catalyst was carried out by reducing Ag+ in ZIF-8 suspension in the presence of thiol-containing mercaptopropionic acid (MPA) molecules. The result demonstrates that the performance improvement in CO2 electroreduction over Ag/ZIF-8 is probably attributed to the small-size of Ag NPs and the synergistic effect between Ag NPs and ZIF-8.

Article 6: Effect Of Surfactant Type On The Characteristics And Bioactivity Of Mesoporous Bioactive Glasses

The sixth article of the issue is from Hediyeh Nejati Rad et al., from Materials and Energy Research Center (MERC) and Iran University of Medical Sciences, Iran. In this study, mesoporous bioactive glass 77S was synthesized by sol-gel method using two different ionic and nonionic surfactants. Then, the physical-chemical properties of synthesized Bioglass were studied using several techniques (X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, etc.). Here, the results showed that using nonionic and ionic surfactants increased specific surface area by 3 and 5 times, respectively. The result demonstrates that the pH analysis results suggested a direct relation between surface area and pH changes. The greatest increase in pH was observed in the sample with the highest surface area.
