A 3D printing approach for precise cell placement on tissue engineered scaffolds is developed.
The possibilities of using photoacoustic techniques as a versatile tool for lympathic-related clinical applications is discussed.
Intercellular communication may provide a mechanism to exploit and buffer cell-to-cell variability.
To increase the structural efficiency of composite aircraft requires further optimization of aeronautical structures to maximally exploit the material performance.
Scientists discover a way to harvest fresh water from air, also in arid regions.
Clinically approved hydrogels can be structured across multiple length scales to generate materials with a variety of new physical properties.
A scalable method for fabricating electronic whiskers (e-whiskers)—a class of electronic skin—for sensing a variety of external stimuli, including proximity, texture mapping, surface roughness, material stiffness, force, and temperature.
Various approaches for converting CO2 and H2O to liquid hydrocarbons using solar energy involve electro/photo/thermochemical catalytic processes and combinations thereof exist.
Imagine a scenario where CO2 greenhouse gas emissions could be used to desalinate briny water. This would be a creative way of killing two birds with one stone, namely helping to ameliorate global-warming-induced climate change and producing high quality water for agriculture and drinking purposes.
