To combat the global problem of CO2 emissions, H2 is the desired energy vector for the transition to environmentally benign fuel cell power. Water electrolysis (WE) is the major technology for sustainable H2 production. Despite the use of renewable solar and wind power as sources of electricity, one of the main barriers for the widespread implementation of WE is the scarcity and high cost of platinum-group metals (PGMs) that are used to catalyze the cathodic hydrogen evolution reaction (HER) and the anodic oxygen evolution reaction (OER). Hence, the critical PGM-based catalysts must be replaced with more sustainable alternatives for WE technologies to become commercially viable. This critical review describes the state-of-the-art PGM-free materials used in the WE application. Several emerging classes of HER and OER catalysts are reviewed and detailed structureproperty correlations are comprehensively summarized. The influence of the crystallographic and electronic structures, morphology, and bulk and surface chemistry of the catalysts on the activity towards OER and HER is discussed.

Polymer and composite materials are becoming more and more widely used in the Russian automotive industry. The Russian market of polymer materials for automotive components is characterized by an insufficiently developed production of some types of such materials. And, as a result, the use of imported materials. Styrene plastics are one of the innovative materials for the automotive industry. Using them in a car makes the product more attractive to customers. The use of this type of plastics allows to create a new look for the car. This applies to both the interior and exterior. The aim of this work is to develop the composition of a polymer composition based on ABS plastic from domestic raw materials. In addition, the new mixed composition should replace imported mixed compositions or contain a minimum amount of imported components of the composition, which will significantly reduce the cost of products and accordingly the car. The article analyzes the polymer materials used in the automotive industry. The disadvantages of using these materials in their pure form are revealed. The selection of the components of the composition of the impact-resistant material with the development of its formulation has been made. The composition of an impact-resistant polymer composition based on ABS plastic and PC has been developed, which is not inferior in terms of the complex of properties to the imported material. The influence of the composition of ABS-plastic, various grades of polycarbonate, their ratio in the polymer composite material on the physical, mechanical and technological properties of the obtained composition has been investigated. It is shown that the best set of properties is possessed by a material based on 2020-30 ABS-plastic and PC-3S polycarbonate with a component ratio of 70%:30%.

Engineering Practices

Humans realised the importance of housing since the dawn of history. The first man used the caves as shelter. When agricultural activities dominated the life style of humans, villages started to be constructed. Later these were developed into cities. The dawn of civilization started in Iraq. The inhabitants in that time used the available natural materials in their construction. Reviewing the progress of engineering practices of ancient Iraq, reveals the facts that the inhabitants were aware of the principles of construction and engineering. The materials used and the design of the buildings were very suitable from both environmental and engineering perspectives. This work is a critical review of the progress and development of engineering practices and construction materials used in ancient Mesopotamia

Absorption Measurements

Normally, small differences in day-to-day and laboratory-to-laboratory sound absorption measurements do not have large consequences because most noise control applications are not highly sensitive to small changes in sound absorption. However, in the automotive industry, materials are not purchased unless they meet strict sound absorption targets. As a result, decisions worth millions of U.S. dollars are made based on acoustic measurements. As material sound absorption moves closer to target values, the consequences of small measurement variations, such as those which might be caused by changes in ambient temperature and humidity during the course of a test, become more critical. The purpose of the work presented in this paper is to investigate which materials used for vehicle sound absorption are sensitive to temperature and humidity. Measurements are made using an impedance tube. It is discovered that typical materials used as absorbers in automotive applications are not sensitive to small temperature changes, and only a few materials are sensitive to changes in humidity.
