Published: Feb. 17, 2023

With the ultimate atomic utilization, well-defined configuration of active sites and unique electronic properties, catalysts with single-atom (SASs) exhibit appealing performance for electrocatalytic green hydrogen generation from water splitting further utilization via hydrogen-oxygen fuel cells, such that a vast majority synthetic strategies toward SAS-based (SASCs) are exploited. In particular, room-temperature electrosynthesis under atmospheric pressure offers novel, safe, effective route to access SASs. Herein, recent progress in ambient SASs sustainable future opportunities discussed. A systematic summary is started on three kinds electrochemically routes SASs, including electrochemical etching (ECE), direct electrodeposition (DED), leaching-redeposition (ELR), associated advanced characterization techniques. Next, their applications energy conversion evolution reaction, oxygen overall splitting, reduction reaction reviewed. Finally, brief conclusion remarks challenges regarding development high-performance cost-effective SASCs many other presented.

Pore-engineered nanoarchitectonics for cancer therapy

NPG Asia Materials, Journal Year: 2023, Volume and Issue: 15(1)

Published: March 31, 2023

Abstract Nanoarchitectonics describes the integration of nanotechnology with other fields as a postnanotechnology concept that elevates it to material science. Based on this fundamental principle, we address pore-engineered nanoarchitectonics application targets for cancer therapy by combining basic descriptions and exemplifying applications in review. The initial two sections briefly summarize basics according classification based (i) porosity (ii) composition. Afterward, main application-oriented section—designing mesoporous therapy—is presented. Various types drug delivery systems, including nanoparticles nanocarriers, endogenous stimuli-responsive delivery, exogenous targeted are described. Importantly, clinical translation materials is further discussed. Mesoporous unique offer network cavities vehicles nanocarriers. Regarding developments allow be broadly used settings, there several challenges should solved their application. From perspective, tremendous processes development materials.

Molecular Mechanism Behind the Capture of Fluorinated Gases by Metal–Organic Frameworks

Nano-Micro Letters, Journal Year: 2025, Volume and Issue: 17(1)

Published: Jan. 27, 2025

Abstract Fluorinated gases (F-gases) play a vital role in the chemical industry and fields of air conditioning, refrigeration, health care, organic synthesis. However, direct emission waste containing F-gases into atmosphere contributes to greenhouse effects generates toxic substances. Developing porous materials for energy-efficient capture, separation, recovery is highly desired. Recently, as designable adsorbents, metal–organic frameworks (MOFs) exhibit excellent selective sorption performance toward F-gases, especially recognition separation different with similar properties, showing their great potential control recovery. In this review, we discuss capture azeotropic, near-azeotropic, isomeric mixtures various application scenarios by MOFs, specifically classify analyze molecular interaction between interpret mechanisms underlying high regarding both adsorption capacity selectivity, providing repertoire future design. Challenges faced transformation research roadmap MOFs adsorbent technologies are also discussed, areas endeavors highlighted.

Abstract Thermal management is a key link in improving energy utilization and preparing insulation materials with excellent performance the core technological issue. Complex irregular pore structures of hinder exploration structure‐property relationships further promotion material performance. Ordered mesoporous silica (OMS) kind porous ordered frameworks. This work elucidates effects architecture on thermal conductivity silica. Herein, two typical OMS, SBA‐15 SBA‐16, characterized by well‐defined distinct spatial orientations are synthesized to study relevance between structure conductivity. Compared 3D cubic 2D hexagonal exhibits anisotropic that restrict both solid gaseous conduction, thereby providing better insulating. Due influence porosity, found decrease strongly increasing size decreasing wall thickness. Moreover, OMS composite aerogels outstanding insulation, mechanical performance, hydrophobicity fabricated through incorporating into cellulose nanofibers (CNF). Consequently, this contributes deeper understanding heat transfer provides an idea for designing OMS‐based materials, advancing their potential applications.

Although some these rather challenging, many barriers overcome, we suggest fostering research directions as maintaining crucial catalysts. Discussion science technology is organised consideration three possible scenarios: (i) BAU (business-as-usual) scenario (ii) two advanced scenarios, differ terms degree circularity (low high, LC HC respectively), (iii) level substitution fossil fuels alternative energy carbon sources.
