Direct Synthesis of Acetic Acid from Carbon Dioxide and Methane

, 2005
The catalytic activation of carbon dioxide in reactions with methane has been investigated. Of specific concern was the direct synthesis of acetic acid from methane and carbon dioxide using a heterogeneous catalyst: CO2 + CH4 -> CH3COOH DGr0 = + 71 ...

Oral Astilbin Nanogels Modulate Senescence‐Associated CD4+ T Cells and Promote Treg Induction in Aged Mice with Colitis

Advanced Science, EarlyView.
Fluorinated β‐glucan/pectin nanogels enable colon‐targeted oral delivery of astilbin through gastrointestinal protection, β‐glucanase‐responsive release, mucus penetration, and prolonged retention. The released astilbin attenuates senescence‐associated features of CD4+ T cells and promotes Treg responses, while the nanogel matrix modulates the gut ...

Ionically Counter‐Programmable Phase‐Separation of Superstable Star‐Biopolyamide Coacervates for Electrothermally‐Responsive Pseudosolid Smart Windows

Advanced Science, EarlyView.
We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated

Semi‐Artificial Photosynthesis Enables Light‐Driven Biomanufacturing in Non‐Photosynthetic Bacteria

Advanced Science, EarlyView.
A non‐invasive strategy exploits endogenous H2S metabolism in B. subtilis to drive in situ CdS biomineralization, enabling tight bio‐abiotic contact without genetic modification. Light harvested by the biomineralized nanoparticles powers NADPH regeneration, elevating 2’‐fucosyllactose and surfactin titres two‐ to three‐fold.

Near‐Infrared Triggered Rechargeable Singlet Oxygen Battery for Sustained Phototherapy: Fast Charging and Long‐Lasting Discharging

Advanced Science, EarlyView.
A near‐infrared‐triggered rechargeable singlet oxygen battery based on PBDP nanoparticles is developed. Upon 808 nm irradiation for 5 min, the system enables efficient singlet oxygen generation, reversible storage via cycloaddition, and sustained release for up to 1 h after light cessation.
