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 ...

Prehistoric Grinding Tools as Metaphorical Traces of the Past
Current Swedish Archaeology, 1998 The predominant interpretation of reciprocating grinding tools is generally couched in terms of low archaeological value, anonymity, simplicity, functionality and daily life of women.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Error Compensation for Form Grinding of Gears.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1991 The accuracy of tooth profiles of gears finished by form grinding is strongly affected by positioning errors between the grinding wheel and the work gear, such as errors in the center distance, the inclination angle of the wheel axis and the position of the grinding wheel in the axial direction. In this paper, the effects of these positioning errors on

Defect Analysis of the β– to γ–Ga2O3 Phase Transition
Advanced Functional Materials, EarlyView.The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...
