Samples of 316L SS were manufactured by Laser Engineered Net Shaping (LENS) using different technological parameters. The deposited samples were investigated in terms of microstructure, mechanical properties, phase content and corrosion resistance (salt chamber and electrochemical corrosion). Parameters were chosen to obtain a proper sample built for layer thicknesses of 0.2, 0.4 and 0.7 mm by changing the laser feed rate while keeping the powder feed rate constant. After a comprehensive analysis of the results, it was found that the manufacturing parameters slightly affected the resulting microstructure and also had a minor impact (almost undetectable considering the uncertainty of the measurement) on the mechanical properties of samples. Decreases in resistance to electrochemical pitting corrosion and environmental corrosion with an increased feed rate and a decrease in layer thickness and grain size were observed; however, all additively manufactured samples were found to be less prone to corrosion than the reference material. In the investigated processing window, no influence of deposition parameters on the phase content of the final product was found-all the samples were found to possess austenitic microstructure with almost no detectable ferrite.

The emerging field of quantum life science combines principles from quantum physics and biology to study fundamental life processes at the molecular level. Quantum mechanics, which describes the properties of small particles, can help explain how quantum phenomena such as tunnelling, superposition, and entanglement may play a role in biological systems. However, capturing these effects in living systems is a formidable challenge, as it involves dealing with dissipation and decoherence caused by the surrounding environment.

The focus of this work was to evaluate the differences between the thermal and mechanical effects generated by ultrasound waves on the properties of corn starch, which facilitate the subsequent enzymatic hydrolysis for the generation of porous starches. The results showed that both the thermal and mechanical effects have the capacity to disorganize/alter the structure of starch, impacting on its properties. Characteristics such as particle size, pasting and thermal properties (peak viscosity 1400-1800 cp.

Chinese herbal medicine (CHM) has offered a great treasure and source of inspiration for developing innovative medicinal materials and therapy. In this work, inspired by the macroscopic compatibility of and in CHM, the puerarin (PUE) and CaSO (Ca) as the main constituents, respectively, from the two herbs are co-assembled into two-component molecular hydrogels. Such two-component gels exhibited enhanced mechanical properties compared with the single-component PUE gel due to the introduction of crosslinking hydrogen bonds between PUE and Ca.

Despite advancements in chronic arthritis treatment, there remains a significant demand for advanced nanotechnologies capable of efficiently delivering a wide range of therapeutic agents to provide symptomatic relief and facilitate the healing of inflamed cartilage tissue. Considering the significant impact of hypoxia on the development and maintenance of chondral tissue, replicating its effects on stem cells could be a potential approach for the treatment of osteoarthritis (OA). Cobalt is a prominent hypoxia-inducing agent, owing to its ability to activate the hypoxia-inducible factor (HIF) pathway regardless of cellular oxygen levels.
