Medium‐Entropy Engineering of Magnetism in Layered Antiferromagnet CuxNi2(1‐x)CrxP2S6
Advanced Functional Materials, EarlyView.This study explores the aliovalent substitution strategy with Cu and Cr replacing Ni in Ni₂P₂S₆ compounds to engineer magnetism. By creating CuxNi2(1‐x)CrxP2S6 medium‐entropy alloys, the research reveals the evolution of distinct magnetic phases, including the creation of weak ferromagnetism in intermediate compositions.

Automatic correction of orbital elements using continuous thrust controlled in closed loop
, 2013 This work aims to study and simulate the control of a spacecraft trajectory in order to correct automatically and simultaneously the orbital elements that define the orbit: semi-major axis, eccentricity, periapse argument, inclination and right ascension

Arbitrary spin-to–orbital angular momentum conversion of light
Science, 2017 From spins to spirals The polarization state of light can be used in imaging applications and optical communications. Light can also be structured into vortices that carry optical angular momentum, which can be used for micromanipulation and enhancing ...

Advanced Functional Materials, EarlyView.Self‐aligned gate transistors are developed with a single‐step dielectric passivation and fine‐tuning of source/drain electrode work function using phosphonic acid self‐assembled monolayers (SAM). This transistor architecture minimizes overlap capacitances and access resistance.

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films
Advanced Functional Materials, EarlyView.The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

The Poynting-Robertson Effect and Secular Changes of Orbital Elements [PDF]
arXiv, 2002 The Poynting-Robertson (P-R) effect has been applied to meteoroids for several decades. It is well known that the P-R effect produces only changes in the orbital plane of the particle. The differential equations governing the secular changes in both eccentricity and semi-major axis are known since the time of Robertson, provided the initial orbits are ...
