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 ...

Power transformers condition monitoring using dissolved gas analysis and hidden markov prediction model [PDF]
, 2014 The reason of the power transformer (PT) monitoring is to prevent the failure of the PT. There are many methods to detect the failure of the PT. The methods include Conventional Monitoring System (CMS), Polarization Depolarization Current (PDC) Analysis,

Where to perform the dissolved gas analysis?
Transformers Magazine, 2022 All the readers of Transformers Magazine and attendees of Transformer Academy already realize that DGA is one of the most comprehensive tests for oil-filled electrical devices. Also, readers well understand the complexity of these tests. This aspect is emphasized by all DGA standards, guides, and ample literature and research on DGA methodology.

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.

Where to perform the dissolved gas analysis? - Part II
Transformers Magazine, 2022 In the first part of the column, we presented the advantages of performing DGA analysis in an in-house laboratory. However, nowadays, most of the DGA and insulating tests are performed in an outsourced external laboratory, usually in another country and even continent.

Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
