Alignment, Rising, Sticking, and Phototaxis: Modulating the Behavior of Hematite Micropeanuts

Advanced Materials Interfaces, EarlyView.
Although a rich variety of behaviors, such as rising and phototaxis, are observed with light‐activated semiconductor microparticles, the experimental conditions under which such behaviors occur have not been elucidated. In this study, pH, fuel concentration, and light intensity are varied, revealing diverse behaviors of hematite microparticles.

Massively parallel computation of globally optimal shortest paths with curvature penalization

Concurrency and Computation: Practice and Experience, Volume 35, Issue 2, 25 January 2023., 2023
Abstract We address the computation of paths globally minimizing an energy involving their curvature, with given endpoints and tangents at these endpoints, according to models known as the Reeds‐Shepp car (reversible and forward variants), the Euler‐Mumford elasticae, and the Dubins car. For that purpose, we numerically solve degenerate variants of the

Elliptic Curve Cryptography in Practice [PDF]

, 2014
In this paper we perform a review of elliptic curve cryptography (ECC) as it is used in practice today in order to reveal unique mistakes and vulnerabilities that arise in implementations of ECC. We study four popular protocols that make use of this type of public-key cryptography: Bitcoin, secure shell (SSH), transport layer security (TLS), and the ...

In Situ Manipulation of Growth Mechanisms in the Vapor–Solid–Solid Growth of GaP Nanowires

Advanced Materials Interfaces, EarlyView.
The direct observation of the Ni‐assisted GaP nanowire growth process via transmission electron microscopy reveals two different growth mechanisms by Trimethylgallium (TMGa) precursor supply variations. The decrease of TMGa flow results in the formation of Ni2P phase as growth promoters with cation exchange reaction in addition to interface diffusion ...

IMPLEMENTATION OF BLOM’S KEY PREDISTRIBUTION SCHEME BY USING ELLIPTIC CURVE CRYPTOGRAPHY

Malaysian Journal of Computing, 2021
Cryptography, along with its various methods is used to serve the security communication purpose. Cryptography is said to be secure if the encryption key is hard to break by the attacker.

X‐Ray and Electron Spectroscopy of the CdS/(Ag,Cu)(In,Ga)Se2 Interface With RbF Treatment

Advanced Materials Interfaces, EarlyView.
The chemical and electronic structure of the CdS/(Ag,Cu)(In,Ga)(S,Se)2 interface with RbF treatment is investigated using a combination of synchrotron‐ and laboratory‐based soft and hard X‐ray spectroscopies. A Rb–In–Se species is found at the absorber surface, with a band gap of 2.8 eV, in contrast to comparable Ag‐free Cu(In,Ga)Se2 absorbers with RbF‐
