Operando Electrochemical Formation of Integrated Ni‐Fe Oxyhydroxide Anode for Durable Anion Exchange Membrane Water Electrolyzer

Advanced Science, EarlyView.
The interfacial stability and activity of Ni‐Fe‐based AEMWE anodes can be directly enhanced by operando voltage‐cycling in a FeOOH‐containing electrolyte. This process simultaneously induces Ni oxidation and Fe incorporation, forming an integrated, porous (Fe, Ni)OOH layer with high conductivity and durability.

N‐Doping Activated Presodiation Enhances Sodium‐Ion Provision in Hard Carbon Anodes

Advanced Science, EarlyView.
Introducing pyrrolic‐N sites enables efficient presodiation and stronger PF6− capture, thus pre ‐ forming a robust inorganic‐rich SEI layer in hard carbon anodes. ABSTRACT Hard carbon (HC) is considered the most promising anode material for commercial sodium‐ion batteries (SIBs), yet it still faces critical challenges such as low initial Coulombic ...

The capacitive sensor

2009 32nd International Spring Seminar on Electronics Technology, 2009
This paper is focused on a cavity in LTCC (Low Temperature Co-fired Ceramics), which is one of the methods used for creation of pressure sensor. The mechanical part is 3D structure in which there are integrated electrodes created by TFT (Thick Film Technology). One of them is fixed and the other one is on the deformation element.

Unique and Unclonable Capacitive Sensors

IEEE Sensors Journal, 2018
Inspired from nature, a new concept called 'sensors with unique and unclonable characteristic', has been developed. Such sensors respond to a measurand and provide a unique output. Random variations in the structure of the sensors are responsible for these unique characteristic.

An accurate interface for capacitive sensors

IEEE Transactions on Instrumentation and Measurement, 2002
A new smart interface based on a first-order charge-balanced SC-oscillator is presented for capacitive sensors, which are shunted by a parasitic conductance. In the novel interface, the effect of shunting conductance is reduced by using the charge/discharge method.
