Robust Interlayer Exciton Interplay in a Twisted van der Waals Heterotrilayer on a Broadband Bragg Reflector up to Room Temperature

Advanced Functional Materials, EarlyView.
In this work, we highlight a unique material platform capable of producing three distinct room temperature (RT) photoluminescence (PL) resonances from spatially separated regions composed of a heterobilayer (HBL), a homobilayer (HoBL), and an heterotrilayer (HTL) transition metal dichalcogenide (TMD) heterostructures configuration on a highly ...

The evaluation of Corona and Ikonos satellite imagery for archaeological applications in a semi-arid environment [PDF]

, 2004
Archaeologists have been aware of the potential of satellite imagery as a tool almost since the first Earth remote sensing satellite. Initially sensors such as Landsat had a ground resolution which was too coarse for thorough archaeological prospection ...

Motif Editing for Reaction Pathway Switching From Formate to CO in Single‐Atom Indium Catalysts via Adjacent Carbon Site Manipulation

Advanced Functional Materials, EarlyView.
This work presents manipulation of adjacent carbon site in single‐atom indium catalysts via editing In‐N4 motif to In‐N2O2 for reaction pathway switching. Incorporation of O atoms leads to significant electron enrichment on the adjacent carbon sites surrounding the In‐N2O2 motif, which facilitates *COOH adsorption and CO formation with high selectivity.

Electrostatic‐Attraction‐Driven Self‐Assembled Graphene‐Disordered Rocksalt Composite Cathode for Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A non‐aqueous, solution‐based graphene‐wrapping strategy is shown to stabilize disordered rocksalt LMTOF cathodes without structural degradation. The graphene‐wrapped cathode suppresses oxygen loss and parasitic interfacial reactions, lowers impedance growth, and delivers improved cycling stability and rate capability compared with conventional ball ...

Optimal Design of a Third Pair of Gravity Satellites to Augment Two Existing Polar Pairs to Enhance Earth's Temporal Gravity Field Recovery

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Based on its unique sensitivity to Earth's temporal gravity, and since 2002, the gravity recovery and climate experiment (GRACE) twin satellites, and its successor, GRACE follow-on (GRACE-FO) missions have accumulated a two-decade-long and ...

Decoupling Light Absorption From Photocatalytic Reactivity in TiO2 via Defect and Interfacial Engineering

Advanced Functional Materials, EarlyView.
A hybrid photoprotective material integrates N‐doped TiO2 with a metal‐phenolic network (MPN) to achieve broad‐spectrum attenuation and robust reactive oxygen species (ROS) suppression. Nitrogen doping extends attenuation into the UVA/high energy visible light (HEV) regions and facilitates fast charge recombination to inhibit ROS formation.

Input shaping for control of satellites and formation of satellites

, 2008
Space research is currently in a trend of using smaller satellites in cooperation to achieve the same results of larger, and more expensive, single satellites. Not only that, satellites in formation enable new possibilities, like taking measurements from plasma from different points at the same time, thus creating a more complete 3D profile.
