An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

open access: yesAdvanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

Fiber‐Based Wearable Electronics as Adaptive Biointerfaces for Healthcare Applications

open access: yesAdvanced Functional Materials, EarlyView.
Fiber‐based wearable electronics have been extensively studied as adaptive healthcare biointerfaces. In this review, we classify and introduce fiber‐based systems according to biointerface design, conductive materials, transduction mechanisms, and healthcare applications, and provide a perspective on their translation toward reliable, continuous ...

Optimization of power incoupling and statistical phase distortions by flow shaping of fast axial flow CO2 lasers

open access: yes, 2022
S.536-541In the development of fast axial flow (FAF) high power CO2 lasers the increase of mass flow and the reduction of phase distortions are of main interest in the realisation of high output power with high beam quality.

ON OPTIMAL NOZZLE SHAPES OF GAS-DYNAMIC LASERS [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 1996
Pontryagin's principle is used to study the shape of the supersonic part of the nozzle of a carbon dioxide gas-dynamic laser whose gain is maximal. The exact shape is obtained for the uncoupled approximation of Anderson's bimodal model.

Theoretical estimation of achievable travel rates in inert-gas fusion cutting with fibre and CO2 lasers

open access: yes, 2022
S.215-221Inert-gas fusion cutting is commonly realised with CO2 lasers. However, it has been demonstrated in recent investigations that the use of fibre lasers offers the potential to improve the process efficiency dramatically.

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

open access: yesAdvanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

External cavity diode lasers and non-linear optical frequency conversion in spectroscopic applications [PDF]

open access: yes, 2006
Semiconductor diode lasers are successful tools in atomic spectroscopy. They are routinely used in frequency conversion applications to develop devices that access regions of the spectrum not directly available.

Compound laser modes of mutually delay-coupled lasers : bifurcation analysis of the locking region [PDF]

open access: yes, 2004
A system of two mutually delay-coupled semiconductor lasers with a small delay of 170 ps in the coupling is studied. Apart from a possible difference in their optical frequencies, we consider two identical lasers.

Stabilization of Strongly Reduced Fe(I) Single Atom Species Coordinated in a 2D Self‐Assembled Metal–Organic Network

open access: yesAdvanced Functional Materials, EarlyView.
A graphene‐supported 2D metal–organic network stabilizes highly reactive Fe(I)‐N4 single sites through Co‐induced charge redistribution. Combined experiments and theory reveal Fe(I) formation, oxygen‐driven oxidation, and O2 activation mechanisms, offering a strategy to access low‐valent iron centers relevant to catalytic and biological processes ...
