Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

Advanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Flexible three‐dimensional printed antenna substrates

The Journal of Engineering, 2015
Flexible heterogeneous substrates have been constructed, using three‐dimensional printing in a single process, by introducing air‐filled slots. These substrates have been used to substantially reduce the substrate losses for a flexible microstrip patch antenna causing an increase in its radiation efficiency.

Three-Dimensional (3D) Printing in Orthopedics Education

Journal of Long-Term Effects of Medical Implants, 2020
Three-dimensional (3D) printing is a newly established concept in orthopedics compared with other industries. Surgical applications of 3D printing and tissue engineering have been investigated since the early 2000s, almost two decades after Charles Hull had patented the first device currently in use for additive manufacturing, also known as rapid ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

3D printing of a low-cost videolaryngoscope for tracheal intubation

Scientific Reports
Videolaryngoscopes have been designed to improve the success rate of tracheal intubation on the first attempt; however, their high cost, especially in low- and middle-income countries, is a major disadvantage.
