The influence of the temperature field of the oven on the properties of thermally expanded graphite

Reporter of the Priazovskyi State Technical University. Section: Technical sciences, 2018
Предложена новая методика исследования динамики движения частиц материала в гравитационно-падающем слое с использованием пьезоэлектрического и электроконтактного датчиков. Это позволяет определять скорость витания частиц железографитовых отходов, магнитного графита, а также соединений интеркалированного графита и получить обобщенные кривые по ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

Advanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...
