Hydrogel Adhesive Integrated‐Microstructured Electrodes for Cuff‐Free, Less‐Invasive, and Stable Interface for Vagus Nerve Stimulation

open access: yesAdvanced Healthcare Materials, EarlyView.
In this study, a cuff‐free, less‐invasive surgical approach for vagus nerve stimulation (VNS) by combining ultrathin Y‐shaped kirigami electrodes is developed with a chemically cross‐linked hydrogel adhesive (hydrogel‐kirigami). Unlike conventional cuff implantation, which may damage nerves and nearby critical vessels, this new technique minimizes ...

Morphogenic Growth 3D Printing

open access: yesAdvanced Materials, EarlyView.
I additive manufacturing process exploits the spatial propagation of a polymerization reaction front to produce 3D polymer parts 10× faster and 1000× more energy efficient than the fastest stereolithography. In contrast with existing 3D printing, this morphogenic process is inspired by biological “growth and form” due to the self‐directed propagation ...

Functional Biomaterials Derived from Protein Liquid–Liquid Phase Separation and Liquid‐to‐Solid Transition

open access: yesAdvanced Materials, EarlyView.
Protein can undergo liquid–liquid phase separation and liquid‐to‐solid transition to form liquid condensates and solid aggregates. These phase transitions can be influenced by post‐translational modifications, mutations, and various environmental factors.

Spectral signatures of photosynthesis II: coevolution with other stars and the atmosphere on extrasolar worlds

open access: yes, 2007
As photosynthesis on Earth produces the primary signatures of life that can be detected astronomically at the global scale, a strong focus of the search for extrasolar life will be photosynthesis, particularly photosynthesis that has evolved with a ...

Efficient White Electroluminescence from Cu‐based Perovskite Achieved by High Hole Injection Core/Shell Structures

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a p‐type cuprous sulfide lattice connectedly capping over Cs3Cu2I5 to form lattice‐matched core/shell nanocrystals by controlling the reactivity of sulfur precursor in the synthesis. The resulting pure white PeLEDs achieved by combining with yellow emission CsCu2I3 exhibit a recorded EQE of 3.45% and a high CRI of 91.

The threat to life from Eta Carinae and gamma ray bursts [PDF]

open access: yes, 2001
Eta Carinae, the most massive and luminous star known in our galaxy, is rapidly boiling matter off its surface. At any time its core could collapse into a black hole, which may result in a gamma-ray burst (GRB) that can devastate life on Earth ...

Robotics Vision-based Heuristic Reasoning for Underwater Target Tracking and Navigation [PDF]

open access: yesInternational Journal of Advanced Robotics Systems, Vol.2No3. (2005), 2006
This paper presents a robotics vision-based heuristic reasoning system for underwater target tracking and navigation. This system is introduced to improve the level of automation of underwater Remote Operated Vehicles (ROVs) operations. A prototype which combines computer vision with an underwater robotics system is successfully designed and developed ...
