Modification of silica interfaces by covalent attachment of functional ligands is a primary means of controlling the interfacial chemistry of porous silicas used in separations, environmental cleanup, and biosensing. Recently, modification of hydrophobic, -alkyl-silane-functionalized interfaces has been achieved through self-assembly of zwitterionic phospholipids or mixed-charged surfactants to form "hybrid bilayers", producing interfaces that mimic lipid-bilayer partitioning and provide shape-selective partitioning of aromatic hydrocarbons. Charged headgroups, however, introduce electrostatic interactions that strongly influence the retention of ionizable solutes and require careful control over pH and ionic strength in the solution phase.

The addition of organic cationic iodides to form low-dimensional perovskite is an essential strategy for defect passivation in perovskite solar cells (PSCs). Specially, the 2D/3D perovskite structure can combine the stability of 2D perovskite and the high charge transport performance of 3D perovskite. Here, we introduced phenylammonium hydroiodide salts with different alkyl chain lengths into PSCs precursor solution to research the influence on formation of perovskite thin films and the photovoltaic performance of PSCs.

The aviation industry plays a crucial role in global trade and cultural exchange, but it faces significant challenges due to high production cost and environmental impacts. To achieve carbon neutrality, promoting the development of sustainable aviation fuel (SAF) is essential, with projections indicating that 65% of emissions reductions in the aviation industry by 2050 will come from the use of SAF. Lignin, as an abundant renewable resource, has great potential for conversion into aviation fuel components.

Green, efficient treatment of crude oil spills and oil pollutants is a global challenge, with adsorption technology favored for its efficiency and low environmental impact. The development of an environmentally friendly adsorbent with high hydrophobicity, excellent adsorption performance, and degradability is crucial to overcoming the limitations of petroleum-based adsorbents. Here, a lignin-based polyurethane foam (LPUF) with superhydrophobic and photothermal oil-absorbing properties was fabricated by incorporating octadecyltrimethoxysilane into the foam system.

Electronic address:
Corn starch inclusion complexes of alkyl gallates (typical phenololipid representatives), including stearyl gallate, dodecyl gallate, octyl gallate, and hexadecyl gallate, were synthesized by using a heat treatment method. Such inclusion complexes exhibited significantly improved two-step release properties for gallic acid. In other words, gallic acid was generated via the breakdown of alkyl gallates that were released from inclusion complexes in an everted rat intestinal sac model, as determined by HPLC-UV analysis.
