Controlling a Van Hove singularity and Fermi surface topology at a complex oxide heterostructure interface. [PDF]

Nat Commun, 2019
The emergence of saddle-point Van Hove singularities (VHSs) in the density of states, accompanied by a change in Fermi surface topology, Lifshitz transition, constitutes an ideal ground for the emergence of different electronic phenomena, such as ...

Pseudogap phase of cuprate superconductors confined by Fermi surface topology. [PDF]

Nat Commun, 2017
The properties of cuprate high-temperature superconductors are largely shaped by competing phases whose nature is often a mystery. Chiefly among them is the pseudogap phase, which sets in at a doping $p^*$ that is material-dependent. What determines $p^*$

The Role of Cocrystallization-Mediated Altered Crystallographic Properties on the Tabletability of Rivaroxaban and Malonic Acid

Pharmaceutics, 2020
The present work aims to understand the crystallographic basis of the mechanical behavior of rivaroxaban-malonic acid cocrystal (RIV-MAL Co) in comparison to its parent constituents, i.e., rivaroxaban (RIV) and malonic acid (MAL). The mechanical behavior

Bacterial Biofilm Growth on 3D-Printed Materials

Frontiers in Microbiology, 2021
Recent advances in 3D printing have led to a rise in the use of 3D printed materials in prosthetics and external medical devices. These devices, while inexpensive, have not been adequately studied for their ability to resist biofouling and biofilm ...

Topological states on the gold surface [PDF]

Nature Communications, 2015
AbstractGold surfaces host special electronic states that have been understood as a prototype of Shockley surface states. These surface states are commonly employed to benchmark the capability of angle-resolved photoemission spectroscopy (ARPES) and scanning tunnelling spectroscopy.

Geometrical consideration for mechanical contact between rolling circle and surface roughness as an improvement to the surface profile

Journal of Mechanical Engineering and Sciences, 2021
This paper describes measurement methods of surface profiles that improve contact-type displacement sensor outputs by focusing on the contact point between the sphere tip of the sensor and the rough surface.

Liquids on Topologically Nanopatterned Surfaces [PDF]

Physical Review Letters, 2005
We report here surface x-ray scattering studies of the adsorption of simple hydrocarbon liquid films on nanostructured surfaces-silicon patterned by an array of nanocavities. Two different regimes, filling and growing, are observed for the wetting film evolution as a function of the chemical potential offset from the bulk liquid-vapor coexistence.
