Summary: Due to the lack of effective extraction methods, the importance of extracellular DNA has been overlooked in DNA studies. A novel method using size-controlled mesoporous silica magnetic nanoparticles was proposed, which showed superior DNA adsorption and elution capabilities. This method is promising for extracting extracellular DNA from various environmental samples.

Summary: A combination of hollow melanosomes and carbon black is proposed to mimic hollow melanosomes for the fabrication of amorphous photonic structures (APSs) and non-iridescent structural colors. The APSs show a wide range of structural colors and reflection peaks, which can be controlled by adjusting the diameters of hollow melanosomes, the amount of carbon black, and the mixing ratios. The APSs demonstrate high sensitivity in visual detection for chemicals with similar refractive indices and have potential applications in display, visual detection, information encryption, and anti-counterfeiting.

Summary: A SiO2-C composite was synthesized via sol-gel method using industrial raw materials. The composite consisted of a silica network cross-linked with a carbon network, resulting in a material with sharp pore size distribution and high specific surface area. The carbon and silica networks were subsequently isolated. The synthesized composite and isolated structures were characterized using various techniques and found to exhibit properties suitable for catalysis, immobilization of bioactive molecules and dyes, drug delivery, among others. The carbonaceous network showed a pseudo graphene structure and microdomains of high activity, making it a promising low-cost material for wastewater treatment and drinking water purification in green technologies.

Summary: In this study, an acid-assisted confined self-assembly method (ACSA) was developed to prepare a two-dimensional mesoporous zincophilic sieve (2DZS) as the kinetic interface. The 2DZS interface effectively reduces the anodic polarization of sulfur-based aqueous zinc batteries (SZBs) at high current density, leading to improved lifespan and energy density.

Summary: Photodynamic therapy (PDT) is a promising alternative to traditional active substance release methods, utilizing photosensitizers and specific energy radiation. Curcumin, a natural photosensitizer, has anti-inflammatory, antioxidant, and anti-cancer effects. However, the solubility of curcumin in water limits its clinical application in PDT. Using hierarchical zeolites as carriers is a potential strategy to overcome this difficulty.

Summary: This study explores the synthesis of highly microporous carbons in a facile and sustainable manner, which reduces the use of harsh activating agents and solvents. The role of potassium citrate (PC) as a greener activating agent is investigated in the solvent-free mechanochemical preparation of highly microporous carbon materials from chestnut tannin (CT). The PC-activated carbon materials show high microporosity and are favorable for CO2 adsorption, making them promising for various applications.

Summary: A facile mechanochemical method was used to synthesize ordered mesoporous carbons with well-dispersed metal nanoparticles. The as-prepared carbons exhibited hexagonally ordered cylindrical mesopores with narrow pore size distributions, and the uniform decoration of carbons with small-sized metal particles was essential for high hydrogen storage capacities. This synthesis strategy has great potential in applications such as adsorption and catalysis.

Summary: We investigated the synthesis of ordered mesoporous carbons with tunable mesopores and well-developed irregular microporosity using ecofriendly chemicals as carbon precursors and a triblock copolymer as a soft templating agent. Different block copolymers were used to tailor the structural properties of the resulting carbons. The weight ratios of tannin and block copolymer were employed to adjust the textural properties of the carbons. The obtained CO2-activated carbon samples showed high specific surface area, large pore volume, narrow pore size distribution, and high CO2 uptake.
