Overcoming the sensitivity–speed trade-off in two-dimensional photodetectors via a functional oxide interlayer

Abstract Photodetectors that can achieve both high sensitivity and fast speed remain a challenge due to inherent trade-offs, particularly limiting in photonic integrated circuits. While substantial progress has been made in broadening spect...

High-Q microresonators on 4H-silicon-carbide-on-insulator platform for nonlinear photonics

Abstract The realization of high-quality (Q) resonators regardless of the underpinning material platforms has been a ceaseless pursuit, because the high-Q resonators provide an extreme environment for confining light to enable observations ...

Through-Wall Multiple Targets Vital Signs Tracking Based on VMD Algorithm

Targets located at the same distance are easily neglected in most through-wall multiple targets detecting applications which use the single-input single-output (SISO) ultra-wideband (UWB) radar system. In this paper, a novel multiple target...

Phase-change perovskite metasurfaces for dynamic color tuning

Halide perovskite metasurfaces are attracting increasing interest for applications in light-emitting and display technologies. To access the wide range of colors required for these applications, the main mechanism exploited thus far has bee...

Axial resolution post-processing engineering in Fresnel incoherent correlation holography

Fresnel incoherent correlation holography (FINCH) is a self-interference-based incoherent digital holography method. In FINCH, light from an object point is split into two beams, modulated differently using two lenses with different focal d...

Ostensibly perpetual optical data storage in glass with ultra-high stability and tailored photoluminescence

Long-term optical data storage (ODS) technology is essential to break the bottleneck of high energy consumption for information storage in the current era of big data. Here, ODS with an ultralong lifetime of 2×107 years is attained with sin...

Role of Reference Frames for a Safe Human–Robot Interaction

Safety plays a key role in human–robot interactions in collaborative robot (cobot) applications. This paper provides a general procedure to guarantee safe workstations allowing human operations, robot contributions, the dynamical environmen...

Analysis of Multi Temporal Satellite Imagery for Total Suspended Sediments in a Wave-Active Coastal Area-Gaza Strip Coastal Water, Palestine

Sediment load materials is one of the key factors that determine the surface water quality, both of oceanic and river water, and it specifies water optical properties. Thus it provides a background for a plenty of applications and project...

Multiphase Marine Ramjet Using Liquefied Gas as a Source of Bubbles

An innovative variant of a multiphase marine ramjet is investigated analytically and experimentally. Pressure liquefied gas (LG) is injected, boiling under superheat conditions in the water stream within the propulsion unit, and serving as ...

Mixed Systems of Quaternary Ammonium Foam Drainage Agent with Carbon Quantum Dots and Silica Nanoparticles for Improved Gas Field Performance

Foam drainage agents enhance gas production by removing wellbore liquids. However, due to the ultra-high salinity environments of the Hechuan gas field (salinity up to 32.5 × 104 mg/L), no foam drainage agent is suitable for this gas field....

Comparative effects of organic and inorganic fertilizers on photosynthetic pigments, oxidative metabolism, and yield in cotton (Gossypium hirsutum L.) under semi-arid field conditions

Abstract This study was conducted under field conditions at Harran University’s Osmanbey Campus. Experimental plots were established using a randomized block design. Parameters such as chlorophyll a and b, carotenoids, total soluble protein...

High‐performance optical noncontact controlling system based on broadband PtTex/Si heterojunction photodetectors for human–machine interaction

Abstract Noncontact interaction systems have attracted considerable research attention in recent years because of convenient operation, sterility, and injury prevention. However, the insufficient sensing distance and weak robustness of nonc...
