Nano-assembled thin film gas sensors. 1. Ammonia detection by a porphyrin-based multilayer film. [PDF]

open access: yes, 2006
A thin film of porphyrin deposited by the layer-by-layer method is employed as the active element for an optical sensor. The usefulness of this film technology and the resulting nanoscale matrix for the detection of volatile organic compounds (VOCs ...

An artificially-intelligent cornea with tactile sensation enables sensory expansion and interaction

open access: yesNature Communications, 2023
We demonstrate an artificially-intelligent cornea that can assume the functions of the native human cornea such as protection, tactile perception, and light refraction, and possesses sensory expansion and interactive functions.

Modified Back Contact Interface of CZTSe Thin Film Solar Cells: Elimination of Double Layer Distribution in Absorber Layer

open access: yesAdvanced Science, 2018
Double layer distribution exists in Cu2SnZnSe4 (CZTSe) thin films prepared by selenizing the metallic precursors, which will degrade the back contact of Mo substrate to absorber layer and thus suppressing the performance of solar cell.

Two-dimensional Mo1.33C MXene with divacancy ordering prepared from parent 3D laminate with in-plane chemical ordering

open access: yesNature Communications, 2017
Vacancies in 2D materials can influence their properties, however controlling their formation remains a challenge. Here the authors show that selective etching of a 3D laminate with in-plane chemical ordering results in formation of MXenes with ordered ...

Defect object detection algorithm for electroluminescence image defects of photovoltaic modules based on deep learning

open access: yesEnergy Science & Engineering, 2022
Visual inspection of photovoltaic modules using electroluminescence (EL) images is a common method of quality inspection. Because human inspection requires a lot of time, object detection algorithm to replace human inspection is a popular research ...

Thin-film photonic crystal LEDs with enhanced directionality [PDF]

open access: yes, 2009
The use of photonic crystals for light extraction from light-emitting diodes (LEDs) gives the possibility to shape the farfield emission pattern. This is of particular interest for étendue-limited LED applications that require a more directional ...

Multiplexed neurochemical transmission emulated using a dual-excitatory synaptic transistor

open access: yesnpj 2D Materials and Applications, 2021
The ability to emulate multiplexed neurochemical transmission is an important step toward mimicking complex brain activities. Glutamate and dopamine are neurotransmitters that regulate thinking and impulse signals independently or synergistically ...
