Understanding the Effect of Resistance Temperature Detector Temperature Controllers on Microstructural Alignment in Magnetic Freeze Casting

Advanced Engineering Materials, EarlyView.
The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...

A study of the dynamic mechanical properties of CRTS I type CA mortar [PDF]

Construction and Building Materials, 2016
Abstract Cement and emulsified asphalt mortar (CA mortar) consists of cement, emulsified asphalt, sand, water, and other additives, which can be used as a vibration attenuator and isolation casting layer in modern high-speed railway. However, the dynamic mechanical properties of CA mortar have not been well documented until now.

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 ...
