Perfect shuffle transform based on subwavelength binary blazed grating

open access: yes, 2015
Based on the theory of information optics and the needs of perfect shuffle (PS) transform, a new method of achieving a PS transform is reported by using a subwavelength binary blazed grating (SBBG) array.

Atmospheric Water Harvesting Through Polymer Hydrogel Sorbents: Materials Chemistry, Design Strategies, and Applications

open access: yesAdvanced Science, EarlyView.
Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

Influence of Ru Content on Defect Formation and Electrocatalytic Activity of Au‐Pd‐Pt‐Ru Compositionally Complex Solid Solution Thin Films for the Hydrogen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
Transmission electron microscopy reveals that the formation of planar defects in Au–Pd–Pt–Ru CCSS thin films depends on Ru content, which in turn influences hydrogen evolution reaction electrocatalytic activity. As the Ru content increases, the density of nanotwins initially rises; with further Ru addition, stacking faults form.

Invariants of binary forms [PDF]

open access: yes, 2014
We work over the field of complex numbers. Consider the set V_n of binary forms of degree n, i.e., homogeneous polynomials of degree n in two variables. An invariant of V_n is a polynomial in the coefficients of a form in V_n whose value does not change ...

Liquid‐Metal Interfacial Chemistry for Crystal and Defect Engineering in Two‐Dimensional Post‐Transition‐Metal Materials

open access: yesAdvanced Science, EarlyView.
Liquid‐metal interfaces provide dynamic reaction environments in which crystal growth, composition, and defect formation are intrinsically coupled. This Review reveals how interfacial oxidation, alloy thermodynamics, elemental migration, atmosphere, and processing govern defects in 2D post‐transition‐metal materials, and how these defects can be ...
