Light‑Driven Propulsion of Graphene Aerogels in Microgravity
Advanced Science, EarlyView.Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction
Advanced Science, EarlyView.The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.

Controlling the orbital angular momentum of high harmonic vortices
Nature Communications, 2017 Few methods can produce orbital angular momentum beams in the extreme ultraviolet or X-ray, and controlling orbital angular momentum on these beams remains challenging. Here the authors apply wave mixing to a tabletop high-harmonic source and control the

Mechanism of surface plasmon polarition propagation for nano-optics applications [PDF]
, 2013 In recent times a new emerging research field has become more and more popular in the optics community, which is plasmonics. This discipline studies the surprising optical properties of metals at the nano-scale, which are substantially different from ...

Helical Ince-Gaussian modes as superpositions of Hermite-Gaussian modes
Компьютерная оптикаWe theoretically and numerically investigate helical Ince-Gaussian modes, hIGp,q(x, y, ε). Explicit analytical expressions are derived that describe dependence of the orbital angular momentum of the helical Ince-Gaussian modes at p=2, 3, 4, 5 on the ...

Advanced Science, EarlyView.A compact eight‐channel electrically tunable varifocal metalens with three single‐layer polarization‐multiplexed bi‐focal metalens and three LC cells. The total thickness of the device is ∼6 mm, while the focal lengths can be switched among eight values (3.6, 4.2, 4.5, 4.9, 6.2, 6.9, 8.4, and 9.6 mm). ABSTRACT As an essential module of optical systems,
