Autor: Jere P. Segrest, Chongren Tang, Hyun D. Song, Martin K. Jones, W. Sean Davidson, Stephen G. Aller, Jay W. Heinecke

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-12 (2022)

ATP-binding cassette transporter A1 (ABCA1) drives phospholipid (PL) from the plasma membrane into extracellular apolipoprotein A-I, for the production of high density lipoprotein (HDL). Here, the authors use simulations to assess the mechanism of AB

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-9 (2020)

To what extent the charge carriers can alter phonon heat conduction at environmental temperatures through electron–phonon interactions is an open question. Here, the authors demonstrate substantial reduction in thermal conductivity at high charge c

Report

Hard X-ray Generation and Detection of Nanometer-Scale Localized Coherent Acoustic Wave Packets in SrTiO$_3$ and KTaO$_3$

We demonstrate that the absorption of femtosecond x-ray pulses can excite quasi-spherical high-wavevector coherent acoustic phonon wavepackets using an all x-ray pump and probe scattering experiment. The time- and momentum-resolved diffuse scattering
