Bipolar photovoltaic effect in InSe/MoO3 van der Waals heterostructure for spontaneous light polarization detection

InfoMat, EarlyView.
Bidirectional photo response in a two‐dimensional heterojunction photodetector controlled by light wavelength and polarization. Abstract Polarization is one of the most fundamental properties of light. Traditional polarization‐sensitive photodetectors, however, are limited in their ability to fully extract this information, as they translate the two ...

Automatic Target Recognition (ATR) ATR: background statistics and the detection of targets in clutter

, 1994
This research investigated signal processing oftwo dimensional signals for the detection of targets in noise, particularly in complex background pattern noise. The researchers hypothesized that this type of noise was vulnerable to non-linear processing. They investigated whether the human eye/brain acting as a

Arsonic Acid Functional Polymers Enable Stabilization of Iron Oxide Nanoparticles in Aqueous Solution

Macromolecular Rapid Communications, EarlyView.
Arsonic acid containing diblock copolymers are developed to incorporate arsonic acid moieties for surface anchoring to IONPs, along with water soluble PEG blocks to impart colloidal stability in aqueous environments. The resulting polymer‐coated IONPs are evaluated for stability in physiological media and cytocompatibility.

Synthetic Aperture Radar (SAR) Automatic Target Recognition (ATR) of Ships using Data Augmentation and Deep Learning

, 2021
Automatic Target Recognition (ATR) using Synthetic Aperture Radar (SAR) has become a popular issue in studies, and it’s crucial for water target monitoring. Because SAR imagery are difficult to interpret directly, different machine learning methodologies have been implemented in recent times to recognize maritime objects from SAR data.

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...
