By studying flexible and transparent photodetectors based on single-layer MoS2 under the application of biaxial strain, researchers have developed atomically thin photodetectors whose characteristics can be controlled by means of an externally applied strain. This strain can be reversibly applied through the thermal expansion (shrinkage) of the substrate material, which induces tensile (compressive) biaxial stress. These results...

Despite considerable, decade-long efforts in the field of nanomedicine, fewer nanoparticle technologies than expected have made it to clinical trials. Understanding the role of the nano-bio interface - the protein corona - appears to be a critical factor for successful clinical translation of medical nanotechnologies. New research demonstrates that the protein corona controls the interaction of liposomes with immune cells...

The latest addition in exciting properties of 2D materials has been superconductivity - the complete absence of resistance at low temperatures - clearly exciting for dissipationless (low-power, heating free) electronics. Researchers hypothesized that a layer of hydrogen adatoms could strongly alter the electronic and vibrational features of an atomically thin material, thereby boosting its superconductivity. This idea was...

Manganese oxides have numerous applications in batteries, supercapacitors, microelectronics and (electro)catalysis. Researchers describe a cheap and fast method for depositing conformal thin films of manganese oxide on nanostructured substrates with close-to-a-monolayer precision, competing with the state-of-the-art atomic layer deposition (ALD). The team's redox layer deposition (RLD) is performed in air, at room temperature,...

Researchers demonstrate the feasibility of an environmental moisture-induced, self-powered wearable multifunctional sensing system with the ability to detect both humidity and pressure. The self-powered wearable sensing system is fabricated by integrating a flexible micropatterned pressure-sensitive film on PET as the pressure sensor and attached it onto the back of a PDA power generator. Test results prove that this moisture-powered...

Researchers have fabricated textiles that can protect you from rain, stains, and bacteria, while they harvest the biomechanical energy of the user to power textile-based electronics. These omniphobic triboelectric nanogenerators can be incorporated into any fiber-based textile and be used to power wearable devices using energy harvested from human motion. The team also designed their nanogenerators with large-scale fabrication...

Researchers demonstrate the ease of use of jellyfish biomass as a biodegradable and biocompatible raw material for producing antibacterial mats. They report the successful electrospun-based preparation of novel composite biocompatible nanofibers based on jellyfish biomass. The antibacterial properties of the resulting nanofiber mats were enhanced by incorporating silver nanoparticles within applying an in situ bio-template...
