3D Bioinspired Hair‐Based Solar Evaporator for Efficient Water Harvesting

open access: yesAdvanced Functional Materials, EarlyView.
A bio‐derived solar evaporator inspired by blackbody radiation is developed using human hair waste. The vertically aligned hair structure enables broadband light absorption, efficient thermal localization, and rapid water transport, achieving high evaporation rates and stable desalination performance.

Enzyme‐Regulated Extended Swelling of Hydrogels for Dehiscence‐Less Tissue Expansions

open access: yesAdvanced Functional Materials, EarlyView.
An interpenetrating hydrogel network with swelling under regulation by enzymatic degradation (INSURED) is fabricated to avoid dehiscence. INSURED remains structurally intact post‐implantation, while HYAL injection enables control over the onset and rate of swelling.

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Isolation and Synthesis of Crosslinked Gelatin of Waste Lates Calcarifer Scales Using Gamma Irradiation Induction Technique [PDF]

open access: yes, 2012
In order to use the fisheries waste, isolation of gelatin has been carried out from Lates calcarifer scales and then synthesized to be cross-linked gelatin by induction of gamma irradiation at irradiation dose of 0-50 kGy.

Colloidal Opaline Composites as Throughput‐Scalable, Fully Transparent, and Color‐Tunable Radiative Cooling Exterior Films for Outdoor Photovoltaics

open access: yesAdvanced Functional Materials, EarlyView.
Particular thermal metamaterials are widely used as daytime radiative coolers merely by embedding thermally emissive nanoparticles (NPs) in liquid resins to form scalable, yet highly efficient cooling films in a cost‐effective way. However, randomly dispersed NPs, prevalently used thus far, cause strong scattering, limiting NP content and cooling ...

FT-IR analysis of aerosols in microgravity

open access: yes
Aerosol evolution is a major challenge in climatology. Many questions remain unanswered, especially in the field of cloud microphysics. The aerosols studied here consist of micrometric water droplets formed from a mixture of water-saturated air and HFE7100, and are studied using a set-up that combines optical microtomography and Fourier transform ...
