This work reports the use of chip-based GaN-based micro-LED (μLED) arrays for multifunctional applications as microdisplay, data transmitters, photodetectors, and solar cells. The functions display transmitter have been reported, particularly, we experimentally demonstrated that μLED could be used self-powered, high-performance, wavelength-selective photodetectors (PDs), enabling high-speed multiple-input multiple-output (MIMO) visible light communications (VLC) under on–off keying (OOK)...
The isothermal compression experiments with the strain rates of 0.01–10 s −1 and deformation temperature range 300–420 °C are performed to investigate hot behavior A356 aluminum alloy. Also, complex mechanisms analyzed. It is found that, as gradually increased, flow stress first rises, then stable appears without a tangible peak. microstructures exhibit large elongated grains, only few small new grains appear under most conditions. because dynamic recovery (DRV) dominant softening mechanism....
The dung beetle optimization algorithm possesses robust search and capabilities. However, when it encounters complex challenges, struggles with limited accuracy, restricted global ability, suboptimal results from iterative processes. To address these limitations, this study introduces a multi-strategy improved (CDBO). Initially, the golden sine method is implemented during rolling phase to improve algorithm’s capacity for both late area mining early broad exploration; Then, in order move...
Recent advances in electrochemiluminescence (ECL) leveraging thermally activated delayed fluorescence (TADF) have highlighted its potential for near-unity exciton harvesting. However, there are still very limited examples of TADF-ECL emitters. We present a rigid diboron-embedded multiple-resonance TADF emitter, which exhibits blue–green emission at 493 nm with remarkably narrow bandwidth (FWHM = 22 nm) and minimized singlet-triplet energy gap (ΔEST 0.2 eV), achieving 67% photoluminescence...
The emergence of near-eye displays, such as head-mounted is triggering a requirement for highly enhanced display resolution. High-resolution micro-displays with micro-organic light-emitting diodes (micro-OLEDs) can be preferential candidate, owing to the mature industrialization OLEDs along advantages flexibility, light weight, and ease processing. However, micro-OLEDs pixel sizes down micrometers are difficult achieved using conventional techniques fine metal mask evaporation lithography....
The hot deformation behavior of AZ42 alloy was observed using thermal compression tests at a temperature scope 250-400 oC and strain rate 0.001-1 s-1. True stress-strain curves exhibited combination work hardening dynamic softening features. A Northern Goshawk algorithm (NGO)-optimized artificial neural network (ANN) model proposed. established NGO-ANN demonstrated impressive prediction accuracy, achieving high determination coefficient 0.991, mean absolute percentage error 3.51%, root...
Data-driven modeling based on the shell vibration and acoustic signals of ball mills is normally applied to overcome subjective errors human inference. Many previously proposed selective ensemble (SEN) approaches are "the manipulation input features" from multiinformation fusion perspective, which cannot selectively jointly fuse information hidden in multiscale spectral features under several operating conditions (training samples). Therefore, this study suggests a new soft measuring...

In this scenario, receiving area is not restricted by layer. size-dependent characteristics PD have been investigated detail. Such devices both duplex high-speed VLC. Besides, we demonstrated functions solid-state lighting...
Presents an improved segmentation algorithm for flame image of rotary kiln burning zone, based on Gabor wavelet texture coarseness and Fuzzy C-MEANS (FCM) cluster algorithm. At first, analyses the in detail, divides it into four areas (flame area, material illuminated background area) by expert experiences applies threshold order to get rid area from image. Then carries out general FCM with grey level gets a preliminary membership matrix, calculates filters. last performs Defuzzification...

Meanwhile, trues swiftly with reduced or...
Molecular ferroelectrics (MFs) have been proven to demonstrate excellent properties even comparable those of inorganic counterparts usually with heavy metals. However, the validation their device applications is still at infant stage. The polycrystalline feature conventionally obtained MF films, patterning challenges for microelectronics and brittleness crystalline films significantly hinder development organic integrated circuits, as well emerging flexible electronics. Here, a large-area...
