Design and Construction of Enzyme-Based Electrochemical Gas Sensors
The demand for the ubiquitous detection of gases in complex environments is driving the design of highly specific gas sensors for the development of the Internet of Things, such as indoor air quality testing, human exhaled disease detection, monitoring gas emissions, etc. The interaction between analytes and bioreceptors can described as a “lock-and-key”, in which the specific catalysis between enzymes and gas molecules provides a new paradigm for the construction of high-sensitivity and -specificity gas sensors. The electrochemical method has been widely used in gas detection and in the design and construction of enzyme-based electrochemical gas sensors, in which the specificity of an enzyme to a substrate is determined by a specific functional domain or recognition interface, which is the active site of the enzyme that can specifically catalyze the gas reaction, and the electrode–solution interface, where the chemical reaction occurs, respectively. As a result, the engineering design of the enzyme electrode interface is crucial in the process of designing and constructing enzyme-based electrochemical gas sensors.

Protective Strategies for Magnesium Alloy Vascular Stents
Magnesium alloy stents have been extensively studied in the field of biodegradable metal stents due to their exceptional biocompatibility, biodegradability and excellent biomechanical properties. Nevertheless, the specific in vivo service environment causes magnesium alloy stents to degrade rapidly and fail to provide sufficient support for a certain time.

Recycling of Palladium
Platinum group metals (PGMs), including palladium, play a pivotal role in various industries due to their unique properties. Palladium is frequently employed in technologies aimed at environmental preservation, such as catalytic converters that reduce harmful emissions from vehicles, and in the production of clean energy, notably in the hydrogen evolution process. Regrettably, the production of this vital metal for our environment is predominantly centered in two countries—Russia and South Africa. This centralization has led to palladium being classified as a critical raw material, emphasizing the importance of establishing a secure and sustainable supply chain, as well as employing the most efficient methods for processing materials containing palladium.

Types of Hybrid Bio-Based Aerogel Materials
Bio-based aerogels are derived from various renewable sources such as sugar cane, vegetable oils, proteins, starches, chitosan, alginate, pectin, lignin, cellulose, and proteins, which have been shown to be useful in the production of aerogels. These aerogels have special properties that make them well suited for packaging applications and in bioengineering. Studies in this field have led to advances that shed light on their diverse applications, improved properties, and innovative synthesis methods. Researchers have investigated alternative feedstocks for bio-based aerogels to broaden their sources and enhance sustainability. Studies have explored the use of waste materials, agricultural by-products, and unconventional sources to synthesize aerogels, aligning with the principles of a circular and green economy.

Advantages of 2D Materials and Cellulose in Biosensors
The use of 2D materials in biosensor applications provides several advantages, including excellent mechanical, optical, and electrical properties. These properties are essential for the development of wearable biosensors that enable real-time monitoring of human health information and accurate measurement of vital signs. Integrating 2D materials into wearable biosensors has expanded opportunities for early detection of life-threatening diseases and continuous health tracking. In addition to 2D materials, cellulose-based biosensors also offer significant benefits. They are cost-effective, highly sensitive, and compatible with portable sensing devices used in biomedical applications. One major advancement in this field is the functionalization of cellulose papers with antibodies, nucleic acids, and nanomaterials in PBBs (paper-based bioassays) and μPADs (microfluidic paper-slip devices). Hence, the application of 2D materials and cellulose in medical diagnostics and biosensors has shown great potential. These materials have unique properties that make them suitable for various applications, including disease detection, real-time monitoring, and point-of-care diagnostics.

Water in Epoxy Coatings
The absorption of water strongly affects the exploitation characteristics of epoxy coatings and their lifecycles. The models used for describing water absorption to a polymer matrix involve many parameters that can adequately describe the process with parameter tuning. However, when using multiple variable parameters, the physical essence of absorption can be obscured. Hence, one of the promising directions in this field is the development of new models with fixed physically transparent parameters, which will adequately describe the water uptake process in epoxy resins.

Zn-Pb Metallurgical Slags as Source of Metal Recovery
The mineralogical and chemical characteristics of zinc and lead smelting slags are presented, with particular reference to the slags formed during the simultaneous production of Zn and Pb by the Imperial Smelting Process. These slags, because of the presence of many metals in their composition, mainly in the form of crystalline phases, are a valuable source for their extraction. Slags from Zn-Pb metallurgy are processed on an industrial scale using pyrometallurgical and hydrometallurgical methods, alongside which a number of experiments conducted to recover metals as efficiently as possible, including bioleaching experiments.
