AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

open access: yesAdvanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

World commodity prices 1996 - 1998: Report presented to the AIECE spring meeting, Venice, May 5 - 8, 1997 [PDF]

open access: yes
World commodity prices increased in 1996 on aggregate by 7 percent. However, taking yearly averages, this was the result of heterogeneous developments: increasing oil prices, which have a dominant weight, and falling prices for industrial raw materials ...

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

open access: yesAdvanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Effects of temperature on the microstructural evolution and mechanical properties of copper − bearing medium manganese steel during tempering

open access: yesMaterials & Design
This work introduced the effects of higher tempering temperatures on the microstructural evolution of Cu − bearing medium Mn steel. After quenching steel at 860 °C for 1 h, it was tempered at 600, 640, and 670 °C for 2 h.

Tin Oxide‐Anchored MXene Composites for Enhanced Hydrogen Evolution in Alkaline Media

open access: yesAdvanced Materials Interfaces, EarlyView.
The schematic illustrates a SnO2/MXene heterostructure for efficient hydrogen evolution. SnO2 nanoparticles are uniformly anchored on conductive MXene nanosheets, enhancing charge transfer and catalytic activity. The MXene substrate provides high electrical conductivity and abundant active sites, while SnO2 facilitates water adsorption and dissociation.

Investigation of Structural, Mechanical and Electrochemical Properties of Temperature‐Dependent Dual AlN/TiAlN Coating Synthesized by CVD Process

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates thermally CVD‐deposited AlN/TiAlN dual‐layer coatings over a Si substrate, focusing on the temperature‐dependent process‐structure relationship. Systematic characterization reveals that a dense AlN interlayer combined with an optimally deposited TiAlN top layer provides enhancement in mechanical strength, tribological stability,
