Autonomous Reconfigurable Modular Conductive Hydrogels for Adaptive and Degradable Bioelectronic Interfaces

open access: yesAdvanced Materials Technologies, EarlyView.
Bridging rigid electrodes with soft, irregular tissues demands more than conductivity alone. Modular conductive hydrogels autonomously reconfigure into conformal electrode‐tissue interfaces, coupling mixed ionic‐electronic conduction with tissue‐like mechanics, self‐healing, and degradability.

Breaking Optical Transparency and Electromagnetic Performance Trade‐Offs for Transparent Reflective Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

Purely Equatorial Lasing in Spherical Liquid Crystal Polymer Microlasers with Bipolar Refractive Index Profile

open access: yesAdvanced Optical Materials, EarlyView.
Spherical liquid crystal polymer microlasers with a bipolar configuration confine lasing to a single equatorial plane, allowing precise control over where the laser emission is generated. The anisotropic refractive index profile additionally lifts the energy degeneracy of azimuthal whispering gallery modes, which causes a characteristic splitting into ...

Post‐Deposition Photonic Curing Treatment for Improved Sb2Se3 Photovoltaic Performance

open access: yesAdvanced Optical Materials, EarlyView.
Millisecond‐scale photonic curing overcomes the open‐circuit voltage deficit in Sb2Se3 solar cells by transforming the rear interface. This ultrafast treatment enhances crystallographic texture and smooths the absorber surface, suppressing interfacial recombination and boosting power conversion efficiency to 8.2%.

Stress-time History of Rolls with Grooves

open access: yesTransactions of FAMENA, 2011
In “Steelworks Split” failures of the rolls with grooves on the 3-high-roughing mill stand occurred four times. One part of the failure analysis is an investigation of the service load and corresponding stresses. Numerical analysis of the local stresses revealed maximum stresses on the caliber 7a and on the roll neck.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

open access: yesAdvanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Barn och stress - Specialpedagogens roll i det förebyggande arbetet/Childern and stress - the roll of the education teacher in the stress prevention

open access: yes, 2006
Syftet med följande arbete är att ta del av specialpedagogers uppfattningar, upplevelser och kunskaper om barn och stress. Därigenom kan vi få en ökad kunskap om hur vi identifierar barn som är stressade, om olika stress- och skyddsafaktorer samt hur vi i skolan kan arbeta med stressförebyggande åtgärder.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

open access: yesAdvanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
