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

open access: yesAdvanced 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 ...

Edwards curves and CM curves

open access: yes, 2009
Edwards curves are a particular form of elliptic curves that admit a fast, unified and complete addition law. Relations between Edwards curves and Montgomery curves have already been described.

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

open access: yesAdvanced 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‐

Tuning the Morphological Properties of Granular Hydrogels to Control Lymphatic Capillary Formation

open access: yesAdvanced Materials Interfaces, EarlyView.
Tuning the morphological properties of granular hydrogels is essential to generate robust lymphatic capillary networks that express key lymphatic gene and protein markers. The study demonstrates that 3D in vitro lymphatic tube formation is controlled not by the mechanical properties of the gel, but by the pore size and topology (periodicity) of the gel

Mestre's Finite Field Method for Searching Elliptic Curves with High Ranks

open access: yesJournal of New Theory
The theory of elliptic curves is one of the popular topics of recent times with its unsolved problems and interesting conjectures. In 1922, Mordell proved that the group of $\mathbb{Q}$-rational points on an elliptic curve is finitely generated ...

Sol–Gel Thin Films for the Protection of Ancient Glass Artifacts: A Performance Comparison Between Inorganic and Hybrid Silica Compositions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores the development of sol–gel coatings for archaeological glass conservation. By formulating silica‐based solutions with low acid concentrations and applying them via dip coating, protective films are prepared at room temperature. Analysis reveals that hybrid coatings with methyl and octyl groups provide superior protection against ...

Groups of generalized G‐type and applications to torsion subgroups of rational elliptic curves over infinite extensions of Q

open access: yesTransactions of the London Mathematical Society, 2019
Recently, there has been much interest in studying the torsion subgroups of elliptic curves base‐extended to infinite extensions of Q. In this paper, given a finite group G, we study what happens with the torsion of an elliptic curve E over Q when ...
