Developing low-cost, efficient and stable electrode materials is a major challenge of energy storage and conversion. Here, we report a facile, cost-effective and scaled-up self-sacrificing strategy for transforming commercial stainless steel into highly active and ultrastable electrodes for supercapacitors and the hydrogen evolution reaction. The modified stainless steel displays superior electrochemical activity as well as excellent cycling durability.

The focus on energy efficiency to move towards a more sustainable use of resources has intensified efforts to minimize friction and wear in mechanical systems, which account for 23% of the world's energy consumption. In this study, polyoxometalate ionic liquids (POM-ILs) are introduced as environmentally acceptable lubricant additives, for their potential friction-reducing and anti-wear (AW) properties. These compounds, characterized by their complex structures and tunable properties, have been investigated for their tribological performance across base fluids of varying polarities.

Surface-mediated transmission of pathogens plays a key role in healthcare-associated infections. However, proper techniques for its quantitative analysis are lacking, making it challenging to develop novel antimicrobial and anti-fouling surfaces to reduce pathogen spread via environmental surfaces. This study demonstrates a gelatin hydrogel-based touch transfer test, the HydroTouch test, to evaluate pathogen transmission on high-touch surfaces under semi-dry conditions.

In recent years, a segmental approach to Class II correction has gained popularity among orthodontists. This concept is best represented by the Carrière Motion 3D™ Class II Appliance (CMA), which is an efficient and effective appliance for the treatment of Class II malocclusions. Although it is original and innovative, it also has some inherent flaws that can potentially interfere with its daily use.

A bimetallic organic framework (CuNi-MOF) was synthesized as a corrosion inhibitor using the solvothermal method. The effectiveness of the inhibitor in corrosion prevention of AISI 304 and 316 in 1N hydrochloric acid solution at room temperature was evaluated using weight loss measurements, electrochemical methods, and surface characterization techniques. The formation of CuNi-MOF protective layer on the stainless-steel surface was confirmed through Field Emission Scanning Electron Microscopes (FESEM), Energy Dispersive Spectroscopy (EDS), and X-Ray Diffraction (XRD) analysis.
