Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

open access: yesAdvanced Engineering Materials, EarlyView.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.

Encapsulating Laser‐Induced Graphene to Preserve its Electrical Properties and Enhance its Mechanical Robustness

open access: yesAdvanced Engineering Materials, EarlyView.
It is demonstrated that laser‐induced graphene (LIG) can be encapsulated while preserving its electrical conductivity and enhancing its mechanical properties. Unlike previous encapsulation attempts, the optimal conditions described here result in sheet resistance of ≈2 Ω sq−1, resistance increase of only 5% upon encapsulation, and vastly improved ...

Nano‐Patterned CuO Nanowire Nanogap Hydrogen Gas Sensor with Voids

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
Sub‐5‐ppb hydrogen (H2) detection and sub‐10‐s response and recovery times are achieved based on nano‐patterned polycrystalline CuO nanowires nanogap gas sensors with voids using electron‐beam lithography and unique annealing processes. Pre‐H2 annealing, void‐generating oxidation, and downscaled nanogap electrodes are key to improving the sensing ...

Oxygen consumption of rats with broad intestinal resection

open access: yesBrazilian Journal of Medical and Biological Research, 2000
The study was performed to investigate possible alterations in oxygen consumption in an animal model with broad intestinal resection. Oxygen consumption and the thermal effect of a short meal were measured in rats subjected to short bowel syndrome.

In‐Situ Growth of 2D MOFs as a Molecular Sieving Layer on SnS2 Nanoflakes for Realizing Ultraselective H2S Detection

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The ultraselective H2S detection of the ZIF‐L/SnS2 heterostructure is demonstrated. The introduction of 2‐dimensional (2D) breathable ZIF‐L results in a substantial increase in H2S selectivity attributable to the molecular sieving effect, which impedes the permeation of gases with large kinetic diameters and high polarity.
