Chlorine‐Functionalized Silane‐Modified Copper Electrocatalyst for Enhanced CO2 Reduction to Multi‐Carbon Products

Advanced Science, EarlyView.
A chlorine‐functionalized silane modifier (CPTMS) is introduced to cooperatively regulate CO2 reduction to C2+ products on Cu‐based catalysts. Dual‐functional interface sequentially enhances CO2 activation, intermediates protonation and C─C coupling, delivering a 5‐fold increase in C2+ faradaic efficiency (FE, 75% vs.

Statistics of the electromagnetic response of a chaotic reverberation chamber

Advanced Electromagnetics, 2015
This article presents a study of the electromagnetic re- sponse of a chaotic reverberation chamber (RC) in the pres- ence of losses. By means of simulations and of experi- ments, the fluctuations in the maxima of the field obtained in a conventional mode-

B-Scan in a Reverberation Chamber

IEEE Transactions on Antennas and Propagation, 2016
In this paper, the B-scan technique is applied to a reverberation chamber (RC) for the first time to characterize the time-domain behavior of the chamber. Based on B-scan measurement results, three things are studied in this paper. 1) The statistical behavior of the fields in the time domain is investigated, and it is found that the received power of ...

Targeting the KCNC3‐Dependent Anterior Insular‐Lateral Orbitofrontal Cortex Glutamatergic Circuit Attenuates Post‐Traumatic Anxiety

Advanced Science, EarlyView.
Frontal lobe traumatic brain injury is associated with hyperactivity of an insular–orbitofrontal circuit in both patients and mice. By combination of integrating functional imaging, cell‐type–specific circuit manipulation, single‐cell transcriptomics, and whole‐cell recordings, this work identifies the downregulation of the potassium channel KCNC3 in ...

Experimental Verification of the Weibull Distribution in a Reverberation Chamber

International Journal of Antennas and Propagation, 2019
A Weibull distribution has been proposed for the probability density function (PDF) of the magnitude of the E-field in a reverberation chamber (RC). However, the Weibull distribution has two parameters, and if the parameters are position sensitive, the ...

On the Field Statistics in Nested Reverberation Chambers

IEEE Access
We study the normalized field statistics inside nested reverberation chambers (NRCs), through the analysis of the shielding effectiveness of enclosures and material samples. The accurate knowledge of field statistics allows to improve the estimation of probability distributions for high field values inside electrically large enclosures.

Novel reverberating chamber: the source-stirred chamber

, 2016
The idea of the source-stirred chamber for performing electromagnetic compatibility measurements is introduced in this paper. The electromagnetic field inside the conducting rectangular chamber with arbitrary dimensions is obtained using the corresponding dyadic Green's function.
