Turning agricultural biowaste into high-value 3D-printing materials

Mon, 06/03/2019 - 08:50
Bagasse is a waste plant matter obtained by food industry processes with major potential for several high-value products. An innovative idea of utilizing bagasse is for production of nanocellulose and testing this for wound dressing devices, manufactured by 3D printing. The next step in the development of wound dressings is the personalized aspect of the biomaterials, i.e. wound dressings that are structured and composed of constituents specially selected for a specific wound and wound treatment. Furthermore, sensors could be integrated into wound dressings and thus monitor various aspects of wound development, e.g. moisture and exudates in chronic wounds.

Let's do the twist - rotation-tunable 2D electronics

Fri, 05/31/2019 - 09:59
Researchers commonly observe a relative rotation between individual layers of 2D materials. Importantly, these interlayer rotation angles, i.e. at what angle two individual layers are oriented towards each other, influence the electronic properties of the resulting material system. In new work, researchers reveal a general moire-driven mechanism that governs the interlayer rotation. At the core of these findings is the concept of the van der Waals dislocation, a term the team uses to describe the commensurability/incommensurability defect in bilayer crystalline materials.

Exploration of TiO2 nanoparticle mediated microwave therapy on cancer treatment

Fri, 05/31/2019 - 00:17
The use of TiO2 nanoparticles activated by light and ultrasound has been studied extensively for cancer treatments. For the first time, researchers have shown the nanoparticles can be effectively activated by microwaves for cancer cell destruction - potentially opening new doors for patients fighting cancer. They propose the use of microwaves and TiO2 nanoparticles to induce the production of reactive oxygen species (ROS), which has the potential to be a safer, more effective modality for cancer treatment.
