Nonlinear transmission matrices of random optical media [PDF]
arXiv, 2018 Random media with tailored optical properties are attracting burgeoning interest for applications in imaging, biophysics, energy, nanomedicine, spectroscopy, cryptography and telecommunications. A key paradigm for devices based on this class of materials is the transmission matrix, the tensorial link between the input and the output signals, that ...

Advanced Energy Materials, EarlyView.The transition metal oxide is precisely deposited on the catalyst surface via atomic layer deposition (ALD), forming a protective layer with catalytic activity. Electrochemical experiments, theoretical calculations, and in situ X‐ray absorption spectroscopy (XAS) battery testing collectively demonstrate that the modified transition metal oxide ...

Metropolitan quantum key distribution using a GaN-based room-temperature telecommunication single-photon source [PDF]
arXivSingle-photon sources (SPS) hold the potential to enhance the performance of quantum key distribution (QKD). QKD systems using SPS often require cryogenic cooling, while recent QKD attempts using SPS operating at room-temperature have failed to achieve long-distance transmission due to the SPS not operating at telecommunication wavelength. In this work,

Advanced Intelligent Systems, EarlyView.For safe human–robot collaboration (HRC), a protective and collision‐sensitive robot skin is proposed. The developed robot skin, named Gel‐Skin, is composed of polyvinyl chloride (PVC) gel, which is a functional material with impact absorption capability and tunable piezoresistive characteristics based on electrical charge‐accumulation.
