CdS nanoparticles have wide applications as photocatalysts for degradation of organic pollutants, but due to their limited turnover number and off-pathway charge recombination processes, efficiency is low.
The Taishan Antineutrino Observatory (TAO, also known as JUNO-TAO) is a satellite experiment of the Jiangmen Underground Neutrino (JUNO). A ton-level liquid scintillator detector will be placed at about 30 m from core Nuclear Power Plant. reactor antineutrino spectrum measured with sub-percent energy resolution, to provide reference for future neutrino experiments, and benchmark measurement test nuclear databases. spherical acrylic vessel containing 2.8 ton gadolinium-doped viewed by 10 m^2...
A new concept “polymer synergy” was introduced to develop versatile dopant-free polymer hole transport materials (HTMs) for optoelectronic devices, including solar cells and photodetectors.
The thermal management of MXene (Ti3C2Tx) plays a crucial role in its performance during various emerging applications. However, it is unclear how the inevitable oxidation structure Ti3C2Tx influences dissipation, which might hinder long-term and even create damage. Here we show migration flake with surface film water by combining ultrafast pump–probe technique molecular dynamics (MD) simulations. results demonstrate that at could facilitate interfacial shorter distances but would block...
A bstract We study damping signatures at the Jiangmen Underground Neutrino Observatory (JUNO), a medium-baseline reactor neutrino oscillation experiment.

Compared current experimental...
Laser wireless power transmission (LWPT) systems have significant applications in the field of energy transmission, including spacecraft sensor networks, satellite-to-satellite communication, and remote supply. However, continuous laser exposure increases temperature photovoltaic (PV) cells LWPT system, thus decreasing electrical output performance. This work, which we believe is a new approach, on basis notch film designed by combined merit function proposed to maintain performance while...
High-density silicon waveguide arrays manufactured on a complementary metal-oxide-semiconductor (CMOS)-foundry platform hold great promise for optical information processing and photonic integration. However, evanescent waves arising from nanoscale confinement would cause significant crosstalk in arrays, which remains vital issue various applications. Here, by utilizing nanohole metamaterials, we propose scheme to greatly suppress the devices then demonstrate ultra-compact low-crosstalk...
We report a novel modified Gires-Tournois interferometer (MGTI) starting design for high-dispersive mirrors (HDMs). The MGTI structure combines multi-G-T and conjugate cavities introduces large amount of dispersion while covering wide bandwidth. With this design, pair positive (PHDM) negative highly dispersive (NHDM) providing group delay dispersions +1000 fs2 -1000 in the spectral range 750 nm to 850 is developed. pulse stretching compression capabilities both HDMs are studied theoretically...
Low-dispersion mirrors (LDMs), which require a broad bandwidth, low dispersion, and high damage threshold, are essential optics in ultra-intense ultra-short laser devices. Bragg chirped LDMs do not satisfy these requirements simultaneously. We propose novel LDM (NLDM) based on the hump-like structure quarter wavelength optical thickness (QWOT) to achieve smooth robustness. The spectral dispersion characteristics of two structures compensate for each other, makes up deficiency that bandwidth...
Molecular motion of adamantane confined in activated carbon fiber (ACF) with slit-width 1.1 nm was investigated using solid state 1H, 2H, and 13C NMR analyses. Temperature dependence the 2H spin-lattice relaxation time revealed that undergoes rapid isotropic reorientation ACF is much faster than bulk plastic crystal. line width 1H spectrum also suggests translational ACF. The single minimum potential profile between pore wall might engender high mobility guest molecules as a “two-dimensional fluid.”
The E-MBMS (evolved multimedia broadcast and multicast service) in 3GPP LTE is characterized by the MBSFN (MBMS single frequency network) operation. operation requires that identical signals are transmitted from all base stations at same time frequency. Such requirement implies some restrictions resource allocation may increase needed bandwidth when service areas overlapped. However, overlapping potentially helpful for over-provisioning, hence might be saved. Thirdly, multiplexing of VBR...
