Abstract Tin (II) selenide (SnSe) is an emerging 2D material with many intriguing properties, such as record‐high thermoelectric figure of merit (ZT), purely in‐plane ferroelectricity, and excellent nonlinear optical properties. To explore these functional properties related applications, a crucial step to develop controllable routes synthesize large‐area, ultrathin, high‐quality SnSe crystals. Physical vapor deposition (PVD) constitutes reliable method SnSe, however, effects various growth...
In this paper, Cu-doped carbon quantum dots (Cu-CQDs) were prepared by carrying out thermolysis of Na 2 [Cu(EDTA)] and hydroxylamine hydrochloride at 300 °C for h.The asprepared Cu-CQDs characterized UV-Vis, Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) diffraction (XRD).The exhibited good fluorescence property, high stability, excitationdependent emission behavior a yield 9.8%.More significantly, the...
Based on the electroosmotic reinforcement mechanism of pulsating direct current (PDC) with a high energy efficiency ratio, calculation method PDC electroosmosis drainage rate was verified under different potential gradients using two forms voltage loading, i.e., constant (CDC) and PDC. The weight electric were achieved by laboratory tests, then soil resistivity contact resistance calculated. consumption each test group analyzed considering initial gradient. obtained results show that same...
Porous photoelectrodes show high efficiency in hydrogen production by water splitting. However, fabrication of porous nanorods is usually difficult. Here, we report a simple approach to fabricate kind novel rutile titanium dioxide nanorod array an advanced ion implantation method using multiple-energy helium and subsequent annealing. The nanostructure enhances the photoelectrochemical performance under Uv-visible light illumination, where highest photocurrent density was relatively about 10...
Bandgap engineering is central to the design of heterojunction devices. For heterojunctions involving monolayer-thick materials like MoS2, carrier concentration atomically thin film can vary significantly depending on amount charge transfer between MoS2 and substrate. This makes substrates with a range neutrality levels—as case for complex oxide substrates—a powerful addition electrostatic gating or chemical doping control overlying layers. We demonstrate this approach by growing monolayer...
The controlled vapor-phase synthesis of two-dimensional (2D) transition metal dichalcogenides (TMDs) is essential for functional applications. While chemical vapor deposition (CVD) techniques have been successful sulfides, extending these methods to selenides and tellurides often faces challenges due uncertain roles hydrogen (H2) in their synthesis. Using CVD growth MoSe2 as an example, this study illustrates the role a H2-free environment during temperature ramping suppressing reduction...
Electrostatic catalysis uses an external electric field (EEF) to rearrange the charge distribution boost reaction rates and selectively produce certain products in small-molecule reactions (e.g., Diels-Alder addition), requiring a 10 MV/cm aligned with axis. Such large oriented EEF is challenging for large-scale implementation or material growth multiple axes steps. Here, we demonstrate that energy band at tip of individual single-walled carbon nanotube (SWCNT) can be spontaneously shifted...
Abstract Background Scrub typhus is an acute febrile illness, which was caused by Orientia tsutsugamushi and transmitted through the bite of chiggers. The diagnosis scrub could be missed due to absence pathognomonic eschar. Case presentation A 76-year-old man hospitalized with fever kidney injury diagnosed hemorrhagic renal syndrome first. However, situation illness deteriorated into refractory septic shock multiple organ dysfunction rapidly,although treatment anti-sepsis used in 3rd-5th...
Ion beam irradiation is a powerful method to fabricate and tailor the nanostructured surface of materials. Nanorods on single crystal rutile TiO2 were formed by N+ ion irradiation. The dependence nanorod morphology fluence energy was elaborated. With increasing fluence, nanopores grow in one direction perpendicular burst finally form nanorods. length nanorods increases with under same fluence. development structure originated from formation while N2 bubbles aggregation vacancies responsible...

Electrostatic catalysis has been an exciting development in chemical synthesis (beyond enzymes catalysis) recent years, boosting reaction rates and selectively producing certain products. Most of the studies to date have focused on using external electric field (EEF) rearrange charge distribution small molecule reactions such as Diels-Alder addition, carbene reaction, etc. However, order for these EEFs be effective, a 1 V/nm (10 MV/cm) is required, direction EEF aligned with axis. Such large...
