Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Drip Infusion Cholangiography [PDF]

open access: yesProceedings of the Royal Society of Medicine, 1968
The author has investigated 25 patients with drip infusion cholangiography using 250 ml. of 30% dextrose and 60 ml. of Biligrafin Forte administered intravenously over the course of one hour. The results are compared with 25 patients investigated by conventional intravenous cholangiography with 20 ml. of the same contrast medium. The author concludes

Precise Management of n‐Value Distribution at the 2D/3D Interface Enabling Efficient Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
This study elucidates the phase transition pathway of surface‐engineered perovskite films. During spin‐coating, n = 1 2D perovskite dominantly forms, while subsequent annealing drives OA+ release and induces conversion to higher n‐value 2D phases.

Drop‐Location‐Insensitive Droplet‐Based Electricity Generator Using Polydimethylsiloxane Slippery Covalently Attached Liquid Coatings

open access: yesAdvanced Science, EarlyView.
Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

Synergistic Additive and Bulky Cation Engineering via a Sequential Vacuum Dry‐Dipping Process for Tin Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
A spin‐coating‐free sequential blade–dipping process is developed for efficient tin perovskite solar cells. Amorphous SnI2 templates are blade‐coated and vacuum‐dried, followed by a vertical dipping conversion. Enhanced by a synergistic additive matrix and bifunctional BATo cation, the resulting devices achieve a benchmark power conversion efficiency ...

Multi‐Scale Bionic Structure Constructs Biomass Flame‐Retardant Thermal Insulation Foam Material

open access: yesAdvanced Science, EarlyView.
Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...
