Elucidating protonation pathways in CO2 photoreduction using the kinetic isotope effect

Nature Communications
The surge in anthropogenic CO_2 emissions from fossil fuel dependence demands innovative solutions, such as artificial photosynthesis, to convert CO_2 into value-added products. Unraveling the CO_2 photoreduction mechanism at the molecular level is vital

Modulation of oxygen vacancies and hot electrons promotes highly efficient CO2 photoreduction towards C2H6

Nano Research
Efficient CO2 photoreduction towards C2+ solar fuels has emerged as one of the most promising strategies for alleviating the current energy and environment problems. However, the C-C coupling barriers and complex multi-electron transfer steps still limit

Photoreduction and incorporation of iron into ferritins [PDF]

Biochemical Journal, 1990
Pea seed ferritin is able to incorporate ferrous iron into the mineral core. Fe2+ may be formed by reduction of exogenous Fe3+ with ascorbate or by photoreduction by ferritin and by ferric citrate. In our experimental conditions the bulk of the photoreduction is carried out by ferritin, which is able to photoreduce its endogenous iron. Citrate does not

Charge Storage and Dark Photocatalysis in Multivariate Ti‐Based Metal‐Organic Frameworks

Advanced Materials, EarlyView.
The mixed‐linker series of the titanium‐based metal–organic framework COK‐47 enables systematic tuning of photoresponsiveness and (dark) photocatalytic activity, deepening our understanding of structure‐property‐function relationships. Tailored metal‐to‐ligand charge transfer between the secondary building units (metal‐oxo layers and organic linkers ...

4D–Printed Photothermally Actuated Soft Microgripper on an Optical Fiber Tip for Biomedical Applications

Advanced Materials Technologies, EarlyView.
In this study, we developed a light–driven soft microgripper by 3D–printing a photo–crosslinkable, temperature–responsive hydrogel with embedded silver particles onto an optical fiber tip. The microgripper actuates via photothermal effects at cell culture temperature and can gently grasp spheroids without minimal damage, offering a compact, actuator ...
