Pulsed Electric Fields' Impact on Milk's Nutritional Composition
Milk processing can cause the demolition of the milk fat globule membrane and induce interactions between whey protein and casein with membranes, leading to changes in pH, protein, and lactose content, as well as the destruction of vitamins and enzymes, hydrolysis of proteins and lipids, disruption of calcium and phosphorus equilibrium, and reduction of the cream layer. Pulsed electric fields (PEF) are gaining recognition in food processing due to their energy efficiency, minimal energy loss, flexibility, instantaneity, non-thermal nature, and environmental friendliness. It has also been found to reduce spoilage by microorganisms and the inactivation of undesirable enzymes, as well as its better retention of organoleptic and nutritional characteristics.

All-Solid-State Lithium–Oxygen Batteries
All-solid-state lithium–oxygen batteries (ASSLOBs) are emerging as a promising next-generation energy storage technology with potential energy densities up to ten times higher than those of current LIBs. ASSLOBs utilize non-flammable solid-state electrolytes (SSEs) and offer superior safety and mechanical stability. However, ASSLOBs face challenges, including high solid-state interface resistances and unstable lithium-metal anodes.

Rent Regulation
Rent regulation is a system of laws, administered by a court or a public authority, which aim to ensure the affordability of housing and tenancies on the rental market for dwellings. Generally, a system of rent regulation involves: The classic objective is to limit the price that would result from the free market. The loose term "rent control" can apply to several types of price control: Comprehensive rent regulation is common in Commonwealth and European Union countries, including Canada, Germany, Ireland, Cyprus, Sweden, and four states in the United States . A majority of OECD countries maintain rent-regulation laws, some changing to softer rent controls. A 2009 review of the economic literature:106 by Blair Jenkins through EconLit covering theoretical and empirical research on multiple aspects of the issue, including housing availability, maintenance and housing quality, rental rates, political and administrative costs, and redistribution for both first generation and second generation rent control systems found that “the economics profession has reached a rare consensus: Rent control creates many more problems than it solves”.:105 :1 :1 :1

Sea Waste to Enhance Sustainability in Composite Materials
The term “sea waste” generally refers to any solid, liquid, or gaseous material or substance that is discarded, disposed of, or abandoned in the ocean, sea, or any other body of salty water, such as a lagoon, etc. This includes waste generated by human activities on land that makes its way into the ocean, as well as waste generated by ships and other vessels at sea. Examples of sea waste include plastic debris, chemicals and toxic substances, oil spills, sewage, and other forms of pollution. These pollutants can harm marine ecosystems, endanger marine life, and impact human health and wellbeing. Sea waste can be recovered by its use into composite materials, as their reinforcement or as their matrix.

Application of Non-Destructive Testing Techniques to Characterize Nanocarriers
The synthesis of tailored and highly engineered multifunctional pharmaceutical nanocarriers is an emerging field of study in drug delivery applications. They have a high surface-area-to-volume ratio, aiding the targeted drug’s bio-distribution and pharmacokinetic properties. Therefore, the characterization of nanocarriers is critical for understanding their physicochemical properties, which significantly impact their molecular and systemic functioning. To achieve specific goals, particle size, surface characteristics, and drug release properties of nanocarriers must be managed. An overview of the applications of non-destructive testing techniques (NDTT) to reveal the characteristics of nanocarriers, considering their surface charge, porosity, size, morphology, and crystalline organization. The compositional and microstructural characterization of nanocarriers through NDTT, such as dynamic light scattering, X-ray diffraction, confocal laser scanning microscopy, ultraviolet-visible spectroscopy, scanning electron microscopy, atomic force microscopy, and nuclear magnetic resonance spectroscopy, have been comprehensively reviewed. Furthermore, NDTT is only used to characterize physicochemical parameters related to the physiological performance of nanocarriers but does not account for nanocarrier toxicity. Hence, it is highly recommended that in the future, NDTT be developed to assess the toxicity of nanocarriers. In addition, by developing more advanced, effective, and precise techniques, such as machine vision techniques using artificial intelligence, the future of using NDTT for nanocarrier characterization will improve the evaluation of internal quality parameters.

Photoactive Heterostructures
In this study we consider the results on the development and exploration of heterostructured photoactive materials with major attention focused on what are the better ways to form this type of materials and how to explore them correctly. Regardless of what type of heterostructure, metal–semiconductor or semiconductor–semiconductor, is formed, its functionality strongly depends on the quality of heterojunction. In turn, it depends on the selection of the heterostructure components (their chemical and physical properties) and on the proper choice of the synthesis method. Several examples of the different approaches such as in situ and ex situ, bottom-up and top-down, are reviewed. At the same time, even if the synthesis of heterostructured photoactive materials seems to be successful, strong experimental physical evidence demonstrating true heterojunction formation are required. A possibility for obtaining such evidence using different physical techniques is discussed.

Medical Ventilator
A medical ventilator (or simply ventilator in context) is a machine designed to provide mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently. While modern ventilators are computerized machines, patients can be ventilated with a simple, hand-operated bag valve mask. Ventilators are chiefly used in intensive care medicine, home care, and emergency medicine (as standalone units) and in anesthesiology (as a component of an anesthesia machine). Medical ventilators are sometimes colloquially called "respirators", a term stemming from commonly used devices in the 1950s (particularly the "Bird Respirator"). However, in modern hospital and medical terminology, these machines are never referred to as respirators, and use of "respirator" in this context is now a deprecated anachronism signaling technical unfamiliarity. In the present-day medical field, the word "respirator" refers to a protective face mask.
