Convective heat transfer from circular cylinders located within perforated cylindrical shrouds [PDF]

open access: yes
The influence of perforated cylindrical shrouds on the convective heat transfer to circular cylinders in transverse flow has been studied experimentally. Geometries studied were similar to those used in industrial platinum resistance thermometers.

Novel Use of Laser Zone‐Drawing on Nanofibers Enables Ultra‐Fast Thermal Kinetics and Precise Diameter Control

open access: yesAdvanced Materials Technologies, Volume 10, Issue 8, April 17, 2025.
This work explores the thermal kinetics of laser‐zone‐drawn electrospun nanofibers. Laser‐zone drawing is a technique that allows for localized heating of nanofiber segments, which results in better mechanical drawing. The high surface‐to‐volume ratio of nanofibers allows for ultrafast thermal kinetics at small diameters.

High Strength and Dynamically Tunable Adhesion Enabled by Composite Micropillar Arrays Fabricated via Solvent‐Assisted Molding

open access: yesAdvanced Materials Technologies, Volume 10, Issue 7, April 4, 2025.
Composite micropillar arrays are fabricated with soft polyurethane tips and tunable stiffness shape memory polymer stalks to achieve high strength (>2MPa) and dynamically tunable adhesion (16×). The small scale and material composition enable strong and tunable adhesion, and provide the potential for fast adhesion tuning.

Going from Inner‐Skinned to Outer‐Skinned Polyelectrolyte Multilayer Based Hollow Fiber Nanofiltration Membranes

open access: yesAdvanced Materials Technologies, Volume 10, Issue 8, April 17, 2025.
New negatively charged hollow fiber support membranes with an inverted porous structure are fabricated. These supports are coated with polyelectrolytes to form an outer‐skinned polyelectrolyte multilayer membrane. The membranes show a 3.8x increase in active membrane surface area compared to conventional inner‐skinned polyelectrolyte multilayer ...

Unraveling the Effects of Improved Cooling and Bias Force in the Actuation of a Shape‐Memory Soft Multimaterial Gripper

open access: yesAdvanced Materials Technologies, EarlyView.
This study examines a soft gripper with a NiTiCu6 Shape Memory Alloy (SMA) wire embedded in a graphene nanoparticle (GNP)‐functionalized PDMS matrix. Comparing GNP‐enhanced and plain elastomer prototypes, results show that GNPs improve cooling rates, accelerating release by 40%, but increase energy consumption in low‐current activations.
