Researchers from Hong Kong Polytechnic University and the Hong Kong Polytechnic University Shenzhen Research Institute achieve remote and temporal tuning of luminescence intensity and wavelength in green- and blue-emissive piezophosphors by modulating the magnetic field. This novel method is promising for applications in magnetic optical sensing, piezophotonics, energy harvesting, nondestructive environmental surveillance, novel light sources, and displays.
Ting Zhang and co-workers from the Suzhou Institute of Nano-Tech and Nano-Bionics at the Chinese Academy of Sciences develop a novel superhydrophobic and piezoresistive coating for wearable sensing devices. The coating is durable in harsh conditions and can be used to detect real-time human movement when fabricated as a wearable strain sensor.
A novel, electroluminescent device concept that can emit light in response to the accumulation and distribution of materials on the device surface is developed.
Citizen science projects work best when there is community buy-in, when their purposes are clearly defined at the outset, and when the motivations and skill-sets of all participants and stakeholders are well understood.
A biomolecular adsorption layer (corona) forms on essentially all nanoparticles immersed in biological fluids, and governs their interactions with the biological environment. Key aspects of protein corona formation and its structure and dynamics have yet remained elusive and call for further investigations.
Researchers introduce a new device concept for electroluminescent displays, which does not require transparent electrodes and can be used as remotely readable, spatially-responsive sensors that emit light in response to the accumulation and distribution of materials on the device surface.
Multi-functional, biodegradable hydrogel microparticles that provide information on the authenticity and the potential deterioration of a tagged food or pharmaceutical formulation directly prior to consumption/use is presented.
In this work multifunctional composites of porous piezoelectric foams made of lead zirconate titanate are compared to ecologically beneficial lead-free lithium sodium potassium niobate.
