Janus Electronic Devices with Ultrathin High-κ Gate Dielectric Directly Integrated on 1T'-MoTe.

Integrating high-quality dielectrics with two-dimensional (2D) transition metal chalcogenides (TMDCs) is crucial for high-performance electronics. However, the lack of dangling bonds on 2D material surfaces complicates direct dielectric deposition. We propose using atomic layer deposition (ALD) to integrate ultrathin high-κ dielectric directly on 1T'-MoTe surfaces, facilitating the creation of high-performance back-gated field-effect transistors (FETs).

Robust Plasma-Assisted Growth of 2D Janus Transition Metal Dichalcogenides and Their Enhanced Photoluminescent Properties.

Janus transition metal dichalcogenides (TMDs) are a novel class of 2D materials with unique mirror asymmetry. Plasma-assisted synthesis at room temperature is favored for producing Janus TMDs due to its energy efficiency and prevention of alloying. However, current methods require stringent control over growth conditions, risking defects or unintended materials.

"Ion-imprinting" strategy towards metal sulfide scavenger enables the highly selective capture of radiocesium.

Highly selective capture of radiocesium is an urgent need for environmental radioactive contamination remediation and spent fuel disposal. Herein, a strategy is proposed for construction of "inorganic ion-imprinted adsorbents" with ion recognition-separation capabilities, and a metal sulfide CsGaSnS·HO (FJSM-CGTS) with "imprinting effect" on Cs is prepared. We show that the K activation product of FJSM-CGTS, CsKGaSnS·HO (FJMS-KCGTS), can reach adsorption equilibrium for Cs within 5 min, with a maximum adsorption capacity of 246.

All-in-one treatment: Capture and immobilization of Cs by ultra-stable inorganic solid acid materials HMMoO·nHO (M = Ta, Nb).

Capture and immobilization of Cs is urgent for radioactive contamination remediation and spent fuel treatment. Herein, an effective all-in-one treatment method to simultaneously adsorb and immobilize Cs without high-temperature treatment is proposed. According to the strategy of incorporating high-valency metal ions into molybdates to increase the material stability and affinity towards radionuclides, layered HMMoO·nHO (M = Ta (1), Nb (2)) are prepared.

High-capacity recovery of Cs ions by facilely synthesized layered vanadyl oxalatophosphates with the clear insight into remediation mechanism.

Radiocesium remediation is of great significance for the sustainable development of nuclear energy and ecological protection. It is very challenging for the effective recovery of Cs from aqueous solutions due to its strong radioactivity, solubility and mobility. Herein, the efficient recovery of Cs ions has been achieved by three layered vanadyl oxalatophosphates, namely (NH)[(VO)(HPO)CO]·5 HO (NVPC), Na[(VO)(HPO)CO]·2 HO (SVPC), and K[(VO)(HPO)(PO)(CO)]·4.

Highly Efficient Uptake of Cs by Robust Layered Metal-Organic Frameworks with a Distinctive Ion Exchange Mechanism.

Cs with strong radioactivity and a long half-life is highly hazardous to human health and the environment. The efficient removal of Cs from complex solutions is still challenging because of its high solubility and easy mobility and the influence of interfering ions. It is highly desirable to develop effective scavengers for radiocesium remediation.

An Efficient Uranium Adsorption Magnetic Platform Based on Amidoxime-Functionalized Flower-like FeO@TiO Core-Shell Microspheres.

Efficient removal of uranium (U) from aqueous solutions is crucial for ecological safety. Functionalized magnetic nanoparticles provide a promising strategy for radionuclide recovery and separation. However, designing and synthesizing magnetic adsorbents with high sorption capacity and selectivity, accompanied by excellent stability and reusability, remain a challenge.

[Immune responses of silicotic rats to the antigen of sheep red blood cells].

Objective: To explore the immune response of silicotic rats to sheep red blood cells(SRBC).

Methods: Silicotic rats were immunized with SRBC by tracheal instillation(Group 1) or intraperitoneal injection (Group 2), and non-silicotic rats were immunized by tracheal instillation as normal control(Group 3). The levels of serum hemolytic index(HC50) were measured on 7, 12, 20, 25, and 32 days after primary immunization and 5, 12, 15 days after the second immunization.
