The development of high brightness, small pixel size, and self-emissive light-emitting diodes (LEDs) is deliberately accelerating to replace conventional organic/inorganic LED displays for the virtual/augmented reality market. In this study, we report fabrication process individually well-separated blue-light-emitting InGaN/GaN nanorod arrays on a large-scale wafer detach disperse them in acetone. dispersed individual LEDs are aligned horizontally onto interdigitated pattern with an...
Abstract In this study, an electrochemical biosensor composed of a horseradish peroxidase (HRP)-encapsulated protein nanoparticles (HEPNP) was fabricated for the sensitive and selective detection H 2 O . The HEPNP has three-dimensional structure that can contain large amount HRP; therefore, amplify signals necessary Furthermore, reduced graphene oxide (rGO) used to increase efficiency electron transfer from electrode, which could enhance signal. This showed performance with in range 0.01–100...
Codoping of Ga and N was utilized to realize p-type conduction in ZnO films using rf magnetron sputtering.

The characteristics and the bioassay of controlled release formulations (CRFs) etofenprox which has been used for pest control using a nano-sized chitosan carrier to released amount active ingredients were evaluated. CRF was prepared in three types, ENC1 (M.W. 3000, 0.3%), ENC2 30,000, 0.1%) ENC3 according difference patterns by adjusting molecular weight concentration chitosan. After properties biological activities 3 evaluated, type selected. A shape taken scanning electron microscope...
Thin-film, microscale GaAs solar cells transfer printed into luminescent concentrating waveguides show significantly enhanced power output compared to evaluated in isolation. Experimental and numerical simulation results demonstrate that optimized configurations involve a free-standing waveguide diffuse backside reflector, as way maximize capture of both waveguided scattered photons. Such unusual options engineering design suggest promising additional avenues for the use concentration...
A convenient method to isolate >80% CQD and the fabrication of a non-toxic polymer film which could protect UV-sensitive foods.
Enzyme-based electrochemical biosensors have been widely used because of their sensitivity, rapidity, and highly target-specific reactions. However, the immobilized enzymes can hinder electron transfer on surface electrode decrease sensitivity biosensors. To overcome this problem, we synthesized conductive gold nanoclusters with two sets embedded enzyme nanoparticles, which are called nanocluster-embedded dual-enzyme nanoparticles (AuNC-DENPs) composed a glucose oxidase-stabilized...
Silicon photonics-based optical 1/O is a promising technology direction to meet the ever growing off-chip bandwidth needs of data-intensive computing. While silicon photonic (SiPh) transceivers are increasingly being used in pluggable modules for data center communications, power efficiency and latency constraints their integration XPU/switch packages (such as recent demonstrations [1], [2]) significantly more stringent, requiring different solutions. Ring resonator-based transceiver...

Abstract Micro light‐emitting diodes (μ‐LEDs) are widely adopted in high‐performance display applications due to their exceptional efficiency, brightness, and stability. However, as the chip size decreases, external quantum efficiency (EQE) of μ‐LEDs significantly declines sidewall defects primarily caused by plasma reactive ion etching. In this study, a novel passivation strategy is proposed for using an organic layer, poly(1,3,5‐trimethyl‐1,3,5‐trivinyl‐cyclotrisiloxane) (pV3D3). The layer...
In this article it is shown that high quality single crystalline Ga-doped ZnO (GZO) films could be achieved on ac-plane sapphire using conventional rf magnetron sputtering.
