Sub-nanoscale surface ruggedness provides a water-tight seal for exposed regions in soluble protein structure
(Public Library of Science, 2010-09)
Soluble proteins must maintain backbone hydrogen bonds (BHBs) water-tight to ensure structural integrity. This protection is often achieved by burying the BHBs or wrapping them through intermolecular associations. On the ...

Metallic quantum critical points with finite BCS couplings
(American Physical Society, 2015-11-02)
We study the fate of superconductivity in the vicinity of a class of metallic quantum critical points obtained by coupling a Fermi surface to a critical boson. In such systems there is a competition between the enhanced ...
A supervisory loop approach to fulfill workspace constraints in redundant robots
(Elsevier Science, 2012-01)
An approach based on geometric invariance and sliding mode ideas is proposed for redundancy resolution in robotic systems to fulfill configuration and workspace constraints caused by robot mechanical limits, collision ...
Photo-electrons unveil topological transitions in graphene-like systems
(Nature Publishing Group, 2016-11-11)
The topological structure of the wavefunctions of particles in periodic potentials is characterized by the Berry curvature Ωkn whose integral on the Brillouin zone is a topological invariant known as the Chern number. The ...
Mechanisms of Nucleation and Stationary States of Electrochemically Generated Nanobubbles
(American Chemical Society, 2019-07)
Gas evolving reactions are ubiquitous in the operation of electrochemical devices. Recent studies of individual gas bubbles on nanoelectrodes have resulted in unprecedented control and insights on their formation. The ...
