As the understanding of natural gas hydrates as a vast potential resource deepens, their importance future clean energy source becomes increasingly evident. However, trend towards secondary generation during extraction and transportation, leading to safety issues such pipeline blockages. Consequently, developing new efficient hydrate inhibitors has become focal point in research. Kinetic (KHIs) offer an effective solution by disrupting nucleation growth processes without altering thermodynamic equilibrium conditions. This paper systematically reviews latest research progress development trends KHIs for hydrates, covering history, classification, inhibition mechanisms. It particularly focuses on chemical properties, effects, mechanisms polymer polyvinylpyrrolidone (PVP) polyvinylcaprolactam (PVCap).

Plastics play an indispensable role in modern society, yet their long-term durability poses severe environmental challenges, with mismanaged waste polluting ecosystems worldwide. The transition to a circular economy emphasizes the importance of recycling and resource recovery mitigate these impacts. While conventional disposal methods like mechanical chemical or incineration face limitations such as quality degradation, high costs, pollutant emissions, value-added approaches present innovative solution. This review explores potential integrating recycled plastic into composite materials enhance performance sustainability. Focusing on diverse strategies, paper highlights use plastics combination fibers, wood, metal, concrete, glass, rubber, textiles, foam. These composites demonstrate superior mechanical, thermal, properties, enabling applications across industries construction, automotive, aerospace, furniture. Furthermore, various roles waste—such filler, reinforcement, matrix, additive—are analyzed showcase advancements material innovation. By presenting methodologies outcomes from recent research, this underscores creating high-performance materials, supporting sustainable development economic goals.

A common issue in studies on liquid-phase chemical processes is that the natural solid nanoimpurities present reagent-grade chemicals are ignored. Little known about these impurities’ nature, sizes, concentrations, and behavior, yet they significantly affect efficiency of antiscalants municipal laboratory solutions. Recent research has focused on: (i) estimating nanoimpurity concentrations in-house deionized water semiconductor-grade isopropanol using “light sheet” optical ultramicroscopy, (ii) visualizing antiscalant sorption impurities. Using a fluorescent-tagged aminobis(methylenephosphonic acid) (ADMP-F), we tracked its affinity to particulate matter KCl Our study showed total concentration nanoparticles with size larger than 20 nm 106 units/mL 105 isopropanol. Extrapolation values ≥1 resulted 1011 108 units/mL. The addition or ADMP-F increased foreign nanoparticle populations. selectively adsorbed by only some impurities, while most molecules remain as true solution. To our knowledge, this first instance fluorescently labeled aminoalkylphosphonates being able differentiate traces purity Therefore, role crystallization centers should be seriously reconsidered, especially their important application scale inhibition.

Low sensitivity octahydro-1,3,4,7-tetranitro-1,3,5,7-tetrazocine (HMX) has garnered significant attention from researchers due to its reduced shock sensitivity. However, the crystallization process poses challenges high solidity and viscosity of metastable α phase. Despite efforts address this with additional energy sources like ultrasonic irradiation, prolonged exposure duration often results in small particle sizes, hindering production HMX a consistent size distribution, thus limiting applicability. To overcome these challenges, method combining irradiation trace H

Polyvinyl chloride (PVC) and polyethylene terephthalate (PET) contribute significantly to global plastic waste, with only 9% recycled in recent years. In this work, these wastes were upcycled as functional fillers improve the rigid polyurethane foam (RPUF) properties. To attain target, we leveraged intrinsic polarity of C=O C-Cl groups PVC PET induce intermolecular attractions N-H matrix, evidenced by observed IR peak shifts. This enhanced nucleating effect during foaming, increasing foams’ compressive strengths 77% 22% addition 10% 5% filler, respectively. Furthermore, increased volume. Thus, collective utilization PPW its corresponding impact on CO-based RPUF’s properties signifies a reduction carbon dioxide emissions 14.15% 17.52% for PET, Moreover, thermogravimetric analysis (TGA) differential scanning calorimetry (DSC) revealed improved thermal stability degradation profiles produced RPUFs. Overall, work highlights potential advancement environmentally responsible upcycling strategies common end-of-life wastes, while enhancing

The simple and green pH-based method shows promise for encapsulating hydrophobic molecules in delivery systems to enhance their bioavailability. However, there is still a limited understanding of the pH-induced structural changes that are involved. In this study, we combine experimental techniques with molecular dynamics simulations investigate curcumin crystals. An alkali-acid pretreatment was introduced encapsulate curcumin, where first dissolved an alkaline solution then rapidly acidified form aggregates. Remarkably, these aggregates can be spontaneously encapsulated into emulsions, even at high concentrations (1 mg/mL). Microscopy images suggested disrupts crystalline structure curcumin. Molecular further demonstrated hydroxyl groups hydrogen bonds water molecules, while interactions dominate within pH-treated increase solvent-accessible surface area promote rapid solubilization emulsions or milks.
