Oxygen isotopic evidence for vigorous mixing during the Moon-forming giant impact [PDF]

Science, 2016
Rehomogenizing the Earth-Moon system A giant impact formed the Moon, and lunar rocks provide insight into that process. Young et al. found that rocks on Earth and the Moon have identical oxygen isotopes.

Light‐Fueled In‐Operando Shape Reconfiguration, Fixation, and Recovery of Magnetically Actuated Microtextured Covalent Adaptable Networks

Advanced Materials, EarlyView.
A covalent adaptable network with dynamic disulfide bonds (DS‐CAN) can rearrange its molecular topology through heating or UV irradiation. When combined with ferromagnetic particles, its photoresponsiveness at room temperature enables contactless, spatiotemporal regulation of dynamic bond exchanges during magnetomechanical actuation.

Reconfigurable Liquid Crystal‐Based Physical Unclonable Function Integrating Optical and Electrical Responses

Advanced Materials, EarlyView.
Reconfigurable physical unclonable function (PUF) integrating optical and electrical responses in organic field‐effect transistor is developed by using unique optical fingerprint textures and random molecular alignment of the semiconductive smectic liquid crystal. This approach enhances security by enabling hierarchical authentication, providing robust

Spin‐polarized Acidic Water Electrolysis with Antenna‐Reactor Plasmonic Electrocatalysts

Advanced Materials, EarlyView.
A chiral plasmonic antenna–reactor electrocatalyst, integrating Au nanoflowers as the antenna and iridium single atoms as the reactor, achieves spin‐polarized and light‐driven water electrolysis in acidic media. The catalyst exhibits high activity and durability, enabled by hot‐carrier transfer and the CISS effect, as supported by operando spectroscopy

Compliant Die Attach Process for High‐Conformity Integration of Ultra‐Thin Chips on Curved Surfaces

Advanced Materials Technologies, EarlyView.
A compliant die attach process is developed for bonding ultra‐thin silicon dies onto high‐curvature surfaces. Using FEM‐guided tool design and process optimization, the method achieves excellent surface conformity and minimal voids. This approach offers a reliable solution for next‐generation curved electronics, including LiDAR and wide field‐of‐view ...
