Summary: By developing a gain-embedded cavity magnonics platform, we create a gain-driven polariton (GDP) that is activated by an amplified electromagnetic field. Distinct effects of gain-driven light-matter interaction, such as polariton auto-oscillations, polariton phase singularity, self-selection of a polariton bright mode, and gain-induced magnon-photon synchronization, are theoretically studied and experimentally manifested. Utilizing the gain-sustained photon coherence of the GDP, we demonstrate polariton-based coherent microwave amplification (similar to 40 dB) and achieve high-quality coherent microwave emission (Q > 109).

Summary: A microwave-assisted system was developed for the efficient conversion of acrolein to 3-hydroxypropionaldehyde (3-HPA). The simultaneous cooling method was used to maintain continuous microwave irradiation and stable temperature. The research showed that microwave irradiation reduced the activation energy and accelerated the reaction rate, and the density functional theory calculations confirmed the intensification effect of the microwave field.

Summary: In this study, two different feeds were treated to produce hydrocarbons using HZSM-5 catalyst. The conversion of acetone at high temperatures reached 100% with the production of aromatics centered on C8. However, for mixed ketones, catalyst deactivation was higher, resulting in lower conversion rates and changing product concentrations over time. The highest conversion achieved was 40%.

Summary: Microwave irradiation is known for its selective heating mechanism and has been widely used in organic chemical transformations. This study introduces an innovative one-pot procedure for the synthesis of Cu nanoclusters, demonstrating their successful application in radical cascade annulations of N-alkoxybenzamides to produce various tricyclic and tetracyclic isoquinolones. The supported Cu nanoclusters provide a greener and more efficient platform for synthesis compared to traditional homogeneous methods, reducing the generation of toxic waste and metal contamination in the final products.

Summary: The described radiative cooling chamber replicates radiative cooling and dew formation in the laboratory setting. It allows for the controlled study of dew formation on systems where contact cooling is ineffective, and the investigation of the impact of radiative and wetting surface properties on dew yield. This device is applicable for studying dew itself, its effects on plants and animals, dew atmospheric chemistry, and other natural radiative cooling applications.

Summary: Efficient methods were developed for the synthesis of furan-fused tricyclic compounds using a regiodivergent intramolecular carbometalation strategy. Two different sequences were employed, resulting in 2,3,4,5-tetrasubstituted naphtho[1,2-b]furans and 2,3-disubstituted 4-alkylidene-4H-indeno[1,2-b]furans. These methods provide access to a wide range of polysubstituted naphtho[1,2-b]furans and indeno[1,2-b]furans in a positional selective manner.

Summary: Experimental studies have shown that the use of mesoporous materials can alleviate Ni site deactivation issues under ethene oligomerization conditions. However, in microporous Ni zeolites, the deactivation cannot be eliminated even under conditions of ethene capillary condensation.

Summary: Aldol reaction is a commonly used reaction in chemical synthesis and biochemical domains for constructing new C-C bonds. Traditional aldol reactions use basic catalysts in hydroalcoholic media or strong bases in toxic and flammable organic solvents, which have environmental concerns. In recent years, alternative green methods such as micellar medium, microwave irradiation, and ultrasonics have been developed for aldol condensation. This review summarizes the research on these green strategies.

Summary: Radiant cooling is an energy-efficient technology used in built environments to achieve high thermal comfort, but it faces challenges of condensation risk and insufficient cooling capacity in hot and humid climates. The use of double-skin infrared-transparent membranes (DIMs) can improve cooling capacity and prevent condensation. This study constructed two full-scale radiant cooling chambers with and without DIMs to investigate the effect of DIMs on radiant cooling performance. The results showed that DIMs maintained condensation-free safety and improved cooling capacity compared to conventional radiant cooling without DIMs.

Summary: In this review, various methods for the preparation of new disperse dyes in an environmentally safe and economical way are presented. The use of microwave technology has shown to be a rapid and efficient method compared to conventional methods, with the added benefit of reducing the use of harmful organic solvents. Additionally, the use of microwave and ultrasound technologies in dyeing polyester fabrics at lower temperatures not only saves energy but also provides a higher color depth. Furthermore, the strategy of treating polyester fabrics with nano-metal oxides enhances their properties, such as anti-microbial activity, UV protection, light fastness, and self-cleaning properties. The newly synthesized dyes also exhibit strong biological activity.
