Aiming to improve the photocatalytic activity in N
We demonstrate that bowtie apertures can be used for contact lithography to achieve nanometer scale resolution. The with a 30 nm gap size are fabricated in aluminum thin films coated on quartz substrates. Lithography results show holes of sub-50-nm dimensions produced photoresist by illuminating the 355 laser beam polarized direction across gap. Experimental enhanced transmission and light concentration compared square rectangular same opening area. Finite different time domain simulations...
Abstract The Changjiang River supplies huge amounts of fresh water and dissolved particulate substances to the East China Sea, thereby exerting a great influence on coastal ecosystem. Meanwhile, construction Three Gorges Reservoir (TGR) has reallocated annual discharge, likely affecting transportation carbon in its various forms. transport transformation effect TGR were discussed based three field campaigns, 1 year time series investigation, historical data. Our results indicated following:...
Senescent cancer cells are endowed with high immunogenic potential that has been leveraged to elicit antitumor immunity and potentially complement anticancer therapies. However, the efficacy of live senescent cell-based vaccination is limited by interference from immunosuppressive senescence-associated secretory phenotype pro-tumorigenic capacity cells. Here, a nanovaccine strong immunogenicity favorable for immunotherapy reported. The biomimetic integrating cell membrane-coated nanoadjuvant...
A near-field scanning optical microscope probe integrated with nanoscale bowtie aperture for enhanced transmission is demonstrated. The bowtie-shape allows a propagating mode in the gap region, which enables simultaneous resolution and transmission. characteristics of are demonstrated by measuring near fields produced aperture. It shown that probes have one order magnitude increase over regular shape same resolution. imaging results using agreement those obtained from numerical calculations.
Abstract Aiming to improve the photocatalytic activity in N 2 fixation produce ammonia, herein, we proposed a photochemical strategy fabricate defects, and further deposition of Ru single atoms onto UiO‐66 (Zr) framework. Electron‐metal‐support interactions (EMSI) were built between support via covalently bonding. EMSI capable accelerating charge transfer SAs UiO‐66, which was favorable for highly‐efficiently activity. The production rate ammonia improved from 4.57 μmol g −1 h 16.28 with...
Abstract A plasmonic lens (PL) has the potential to match different length scales associated with photonics and electronics due its subwavelength focusing ability. Most PL fabrication schemes utilize focus ion beam milling or e-beam lithography. However, through aforementioned methods a low throughput high operating cost, making it diffcult scale up for mass production. Here, we numerically report scheme using Fresnel diffraction lithography, in which photolithography is performed field of...
Subarachnoid hemorrhage (SAH), the rarest form of hemorrhagic stroke, is associated with high mortality and disability rates. Therefore, it a major public health concern. This study reviewed epidemiological characteristics SAH in China worldwide, focusing on 2021 Global Burden Disease (GBD) database. Researchers, using GBD database, conducted studies that included joinpoint regression analyses covering incidence, mortality, prevalence, disability-adjusted life years 1990-2021. analysis...
Nanoscale ridge aperture antennas have been shown to high transmission efficiency and confined nanoscale radiation in the near field region compared with regularly-shaped apertures. The enhancement is attributed fundamental electric-magnetic propagating TE(10) mode concentrated gap between ridges.

Abstract Boron nitride (BN), talc, hydroxyapatite (HA), and zinc stearate (ZnSt) were investigated as nucleation agents (NA) for nonfossil‐based poly(3‐hydroxybutyrate‐ co ‐4‐hydroxybutyrate) (P3/4HB) plastics. Nonisothermal crystallization behaviors of the P3/4HB/NA blends examined by DSC. It revealed that BN is most efficient agent to promote rate, however, but not degree. The lasting P3/4HB was also removed. effect strengthened with increase content up 1% then slackened deeply when...
Light emission excited by stable tunnel junctions has attracted interest for potential use in optoelectronic device integration. However, these electrically driven sources cannot provide a high electroluminescence intensity. Here, we report source with 2 orders of magnitude higher output power (1.4 nW). A well-designed optical antenna allows the electromigration process to be located accurately at structure's center. Because subnanometer gap, localized density states is greatly enhanced and...

C-shaped ridge apertures are used in contact nanolithography to achieve nanometer scale resolution. Lithography results demonstrated that holes as small 60 nm can be produced the photoresist by illuminating with a 355 laser beam. Experiments also performed using comparable square and rectangular apertures. Results show enhanced transmission light concentration of C compared regular shapes. Finite difference time domain simulations design explain experimental results.
