Advanced Materials, EarlyView.Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Advanced Materials, EarlyView.Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

IEEE Transactions on Image Processing, 2015
The scene in a water reflection image often exhibits bilateral symmetry. In this paper, we design a framework to reconstruct the depth from a single water reflection image. This problem can be regarded as a special case of two-view stereo vision. It is challenging to obtain correspondences from the real scene and the mirror scene due to their large ...

Depth of ionization chamber in water
Physics in Medicine and Biology, 1995The device developed by the authors and described here enables the user to measure the depth from the water surface to the point of measurement for a cylindrical ion chamber with a waterproof plastic cap in a water phantom, free of surface-tension error with a high precision.

The antiproton depth–dose curve in water
Physics in Medicine and Biology, 2008We have measured the depth-dose curve of 126 MeV antiprotons in a water phantom using ionization chambers. Since the antiproton beam provided by CERN has a pulsed structure and possibly carries a high-LET component from the antiproton annihilation, it is necessary to correct the acquired charge for ion recombination effects.

Water-entry for a wedge in arbitrary water depth
Engineering Analysis with Boundary Elements, 1994Abstract Numerical and experimental results are presented for the two-dimensional entry of a wedge into initially calm water of arbitrary depth. In the numerical computation, the flow field is solved by the boundary element method with nonlinear free surface boundary conditions.

Water Depth Retrieval in the Everglades Using Cygnss
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Quantitative observations of dynamic changes in water extent and depth of the world's wetlands are currently limited by traditional remote sensing methods, which have difficulty observing surface water beneath dense vegetation and clouds. A novel remote sensing technique known as GNSS Reflectometry (GNSS-R) has shown great potential in the detection of

Changes in the depth profile of water in the stratum corneum treated with water
Skin Research and Technology, 2009Background/purpose: Water in the stratum corneum (SC) plays an important role in keeping the skin surface soft and smooth. Information regarding the depth profile of the molecular composition of the skin, such as water and free amino acids, can be obtained non‐invasively using the recently developed confocal Raman spectrometer.

Solar spectrum at depth in water
Renewable Energy, 1991Abstract In pure water, the solar spectrum at various depths from 1 cm to 200 m has been reconstructed. The reconstruction was performed via a computer program. Two sets of data were adopted in this work: the extinction coefficient of pure water in the wavelength range of 300–2500 nm and the solar spectrum at sea level in the same wavelength range.

Water depth influence on wave–structure-interaction
Ocean Engineering, 2009For seakeeping model tests and the experimental investigation of offshore operations the water depth is a parameter which is difficult to adjust to a particular problem and scale. It poses a limit for the feasibility of model tests by governing the model scale-especially in small testing facilities. Therefore, it is often desirable to violate or ignore
