A High‐Current‐Tolerant Multimetallic Phosphide Electrode for Alkaline Water Electrolysis Toward Industrial Conditions

Advanced Science, EarlyView.
A phosphide‐modified multimetallic HER electrode achieves industrial‐level performance with minimal noble‐metal content. It delivers 1.7 A cm−2 at 2.0 V in 6 M KOH at 70°C and operates stably for over 200 h at 500 mA cm−2. Phosphorus tuning of the electronic structure optimizes hydrogen adsorption, offering a durable, high‐rate pathway for alkaline ...

Windthrows Detection With Satellite Remote Sensing Data: A Comparison Among Sentinel-2, Planet, And Cosmo Sky-Med Data

IGARSS 2023 - 2023 IEEE International Geoscience and Remote Sensing Symposium, 2023
Wind disturbances represent a great source of damage in forests, and an assessment of such damage is very important for adequate forest management. Remote sensing is an effective tool for this purpose and can be used by considering different data sources: active vs passive sensors. While passive sensors can provide a direct view of windthrows, they are

Satellites for the detection of nonsolar planets

Journal of Spacecraft and Rockets, 1981
Two sensor systems for the direct detection of nonsolar planets from earth orbit are evaluated: (1) an apodized visual telescope (APOTS), and (2) a spinning infrared interferometer (IRIS). Their performance characteristics and technology requirements for a five-year mission are determined.

Change Detection over the State of Queensland using High Resolution Planet Satellite Mosaics

2019 Digital Image Computing: Techniques and Applications (DICTA), 2019
This paper presents an approach to the automated detection of vegetation level change using a Planet mosaic dataset. The approach is applied to the data set covering the state of Queensland, Australia. This dataset consists of a time series of high resolution (3m2) RGB satellite image mosaics each comprised of approximately 95,000 image tiles.

Ice satellites of planets of the Solar System and the on-orbit radio detection of ultrahigh-energy particles

Uspekhi Fizicheskih Nauk, 2010
The problem of detecting nature's most energetic particles—cosmic rays and neutrinos—is reviewed. Prospects for using orbital radio detectors for these highest-energy particles are examined. Apertures are calculated for space experiments using the Moon and similar-sized ice satellites of planets of the Solar System as targets for the interaction of ...
