Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Spike-timing dependent plasticity and feed-forward input oscillations produce precise and invariant spike phase-locking

Frontiers in Computational Neuroscience, 2011
In the hippocampus and the neocortex, the coupling between local field potential (LFP) oscillations and the spiking of single neurons can be highly precise, across neuronal populations and cell types. Spike phase (i.e.

Paired burst stimulation causes GABAA receptor-dependent spike firing facilitation in CA1 of rat hippocampal slices

Frontiers in Cellular Neuroscience, 2016
The theta oscillation (4–8 Hz) is a pivotal form of oscillatory activity in the hippocampus that is intermittently concurrent with gamma (25–100 Hz) burst events.

Monitoring membrane biofouling via ultrasonic time-domain reflectometry enhanced by silica dosing

, 2012
Detecting biofouling noninvasively in real-time has been a long-standing challenge in membrane processes. Ultrasonic Time Domain Reflectometry (UTDR) offers the potential to address this challenge when used in a ‘canary cell’ that samples a slip stream ...

In Situ Formation of a Highly Selective Nickel Single Atom Catalyst for Electrochemical CO2 Reduction to CO

Advanced Materials, EarlyView.
Development of a novel method for synthesizing Ni single atom catalysts for highly selective electrochemical CO2 reduction in situ. This catalyst achieves 100% selectivity for CO and is formed in an industrially relevant cell architecture. Using post‐mortem XRD, STEM, and EDS and operando XAS, the identity of the active site and the mechanism behind ...
