Advanced Materials Interfaces, EarlyView.A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Multiscale Acoustic Bubble Actuators Using Bioinspired Liquid‐Repellent Microstructures
Advanced Materials Technologies, EarlyView.The article presents multiscale acoustic bubble actuators using bioinspired liquid‐repellent microstructures, enabling programmable trapping, pumping, mixing, and precise flow control. Mimicking springtail microstructures, these scalable actuators (200 µm–1 mm) offer multifunctionality in all‐in‐one devices, letter‐shaped arrays, and 3D cube ...

Ultra‐Thin Soft Pneumatic Actuation for Minimally Invasive Neural Interfacing
Advanced Materials Technologies, EarlyView.Parylene C is a common polymer in bioelectronics, favored for its biological and chemical inertness. However, this makes bonding layers of Parylene C together very challenging. Here it is a laser to selectively weld layers of Parylene C to create high‐pressure fluidic actuation devices.

Green Propellants Based on Ammonium Dinitramide (ADN)
, 2011 Ammonium perchlorate (AP) and hydrazine are today widely used as propellants. AP as oxidizer in solid propellants and hydrazine as liquid monopropellant (Brown, 1995; Sutton and Biblarz, 2001). These propellants are well known for their good performance characteristics, but their limitations and liabilities regarding toxicity, operational handling and ...
