Kavli Affiliate: Ali Javey | Summary:The epitaxial growth of 111 oriented Au on MoS$_2$ is well documented despite the large lattice mismatch (~8% biaxial strain), and the fact that a Au 001 orientation results in much less elastic strain. An analysis based on density functional and linear elasticity theories reveals that the 111 orientation is […]
Kavli Affiliate: Richard Berry | Summary:Recent experiments on the bacterial flagellar motor have shown that the structure of this nanomachine, which drives locomotion in a wide range of bacterial species, is more dynamic than previously believed. Specifically, the number of active torque-generating units (stators) was shown to vary across applied loads. This finding invalidates the […]
Kavli Affiliate: Christopher Ober| First 5 Authors: F. Ober, F. Ober, , , | Summary:Circumstellar disks are considered to be the birthplace of planets. Specific structures like spiral arms, gaps, and cavities are characteristic indicators of planet-disk interaction. Investigating these structures can provide insights into the growth of protoplanets and the physical properties of the […]
Kavli Affiliate: Patricia Burchat | Summary:Wavelength-dependent point spread functions (PSFs) violate an implicit assumption in current galaxy shape measurement algorithms that deconvolve the PSF measured from stars (which have stellar spectral energy distributions (SEDs)) from images of galaxies (which have galactic SEDs). Since the absorption length of silicon depends on wavelength, CCDs are a potential […]
