Effect of Alkali-treatment on Structural, Thermal, Tensile Properties of Dichrostachys Cinerea Bark Fiber and Its Composites

open access: yesJournal of Natural Fibers, 2022
The effect of alkali-treatment of the chemical composition, structure, thermal stability, tensile strength, and surface topology of dichrostachys cinerea bark fibers (DCFs) was analyzed by Chemical analysis, XRD, FTIR, TGA, SEM, and AFM in this ...

Bacterial Biofilm Growth on 3D-Printed Materials

open access: yesFrontiers 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 ...

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

open access: yesPharmaceutics, 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

Topological states on the gold surface [PDF]

open access: yesNature 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.

On the topological index of irregular surfaces [PDF]

open access: yesJournal of Algebraic Geometry, 2006
We study the topological index of some irregular surfaces that we call generalized Lagrangian. We show that under certain hypotheses on the base locus of the Lagrangian system the topological index is non-negative. For the minimal surfaces of general type with q = 4 q=4 and p g

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

open access: yesJournal 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.

Diffusion at the surface of topological insulators [PDF]

open access: yesNew Journal of Physics, 2012
We consider the transport properties of topological insulators surface states in the presence of uncorrelated point-like disorder, both in the classical and quantum regimes. The transport properties of those two-dimensional surface states depend strongly on the amplitude of the hexagonal warping of their Fermi surface.
