Chinese public risk perception and acceptance of Facial Recognition Technology applied in law enforcement.

This study integrates the Perceived Risk Theory and the Unified Theory of Acceptance and Use of Technology, along with factors such as trust and procedural legitimacy, to assess the Chinese public's risk perception and acceptance of Facial Recognition Technology (FRT) in law enforcement. Analyzing 1,561 valid questionnaires collected from February to July 2023, the results demonstrate that trust and procedural legitimacy positively influence public acceptance of FRT. Trust also mediates the effects of perceived privacy and functional risks on FRT acceptance.

Prognostic value of KRAS G12V mutation in lung adenocarcinoma stratified by stages and radiological features.

Objective: KRAS G12V is one of the most common KRAS mutation variants in lung adenocarcinoma (LUAD), and yet its prognostic value is still unrevealed. In this study, we investigated the clinicopathologic characteristics and prognostic value of the KRAS G12V mutation in LUAD.

Methods: Data of 3829 patients who underwent LUAD resection between 2008 and 2020 were collected.

Trace SO capture within the engineered pore space using a highly stable SnF-pillared MOF.

Developing reliable solid sorbents for efficient capture and removal of trace sulfur dioxide (SO) under ambient conditions is critical for industrial desulfurization operations, but poses a great challenge. Herein, we focus on SNFSIX-Cu-TPA, a highly stable fluorinated MOF that utilizes SnF as pillars, for effectively capturing SO at extremely low pressures. The exceptional affinity of SNFSIX-Cu-TPA towards SO over CO and N was demonstrated through single-component isotherms and corroborated by computational simulations.

Roles of the Comproportionation Reaction in SO Reduction Using Methane for the Flexible Recovery of Elemental Sulfur or Sulfides.

SO reduction with CH to produce elemental sulfur (S) or other sulfides is typically challenging due to high energy barriers and catalyst poisoning by SO. Herein, we report that a comproportionation reaction (CR) induced by HS recirculating significantly accelerates the reactions, altering reaction pathways and enabling flexible adjustment of the products from S to sulfides. Results show that SO can be fully reduced to HS at a lower temperature of 650 °C, compared to the 800 °C required for the direct reduction (DR), effectively eliminating catalyst poisoning.

Electron Donation from Boron Suboxides via Strong p-d Orbital Hybridization Boosts Molecular O Activation on Ru/TiO for Low-Temperature Dibromomethane Oxidation.

Low-temperature catalytic oxidation is of significance to the degradation of halogenated volatile organic compounds (HVOCs) to avoid hazardous byproducts with low energy consumption. Efficient molecular oxygen (O) activation is pivotal to it but usually limited by the insufficient electron cloud density at the metal center. Herein, Ru-B catalysts with enhanced electron density around Ru were designed to achieve efficient O activation, realizing dibromomethane (DBM) degradation at 182 °C on RuB/TiO (about 30 °C lower than pristine Ru/TiO) with a TOF value of 0.

Sulfur Dioxide Promoted Mercury Fast Deposition over a Selenite-Chloride-Induced Surface from Wet Flue Gas.

Gaseous elemental mercury (Hg) extraction from industrial flue gases is undergoing intense research due to its unique properties. Selective adsorption that renders Hg to HgO or HgS over metal oxide- or sulfide-based sorbents is a promising method, yet the sorbents are easily poisoned by sulfur dioxide (SO) and HO vapor. The Se-Cl intermediate derived from SeO and HCl driven by SO has been demonstrated to stabilize Hg.

CO sequestration and CaCO recovery with steel slag by a novel two-step leaching and carbonation method.

The steel smelting process produces extensive CO and Ca-containing steel slag (SS). Meanwhile, the low value utilization of steel slag results in the loss of Ca resources. CO sequestration utilizing SS can reduce carbon emissions while achieving Ca circulation.

FeS@MOF-808 composite for efficient As(III) removal from wastewater: behavior and mechanism.

Arsenic is extremely toxic to humans with water as its carrier. One challenge for arsenic control is the complete elimination of As(III) due to its high toxicity, mobility, and solubility. Herein, an active FeS@MOF-808 composite was fabricated to enhance the As(III) removal for wastewater remediation.

Reverse Conversion Treatment of Gaseous Sulfur Trioxide Using Metastable Sulfides from Sulfur-Rich Flue Gas.

Sulfur trioxide (SO) is an unstable pollutant, and its removal from the gas phase of industrial flue gas remains a significant challenge. Herein, we propose a reverse conversion treatment (RCT) strategy to reduce S(VI) in SO to S(IV) by combining bench-scale experiments and theoretical studies. We first demonstrated that metastable sulfides can break the S-O bond in SO, leading to the re-formation of sulfur dioxide (SO).

The Unique CO Activation Effects for Boosting NH Selective Catalytic Oxidation over CuO-CeO.

Slip NH is a priority pollutant of concern to be removed in various flue gases with NO and CO after denitrification using NH-SCR or NH-SNCR, and the simultaneous catalytic removal of NH and CO has become one of the new topics in the deep treatment of such flue gases. Synergistic catalytic oxidation of CO and NH appears to be a promising method but still has many challenges. Due to the competition for active oxidizing species, CO was supposed to hinder the NH selective catalytic oxidation (NH-SCO).

Multi-roles of SO to enhance the removal of arsenic from wastewater in sulfidation processes.

Sulfidation has been an efficient method for arsenic (As) removal from acid wastewater, yet it is inefficient under neutral and weak acid conditions. The higher pH values resulted in the formation of the unstable As-S precipitates, especially employing NaS as the vulcanizing agent as it can increase the pH value dramatically. Here, we found that SO exhibited excellent multi-roles in As removal when applying HS-sulfidation method.

Buffer effect of MgO on NaSO to stabilize S(IV) for the enhancement in simultaneous absorption of NO and SO from non-ferrous smelting gas.

Oxidation-reduction-absorption based on sulfite is a promising process for simultaneous removal of NO and SO. However, excessive oxidation of sulfite and competitive absorption between NO and SO limit its application. A matching strategy between antioxidants and alkaline agents has been proposed to solve these problems and enhance the absorption process.

Regulation of the Sulfur Environment in Clusters to Construct a Mn-SnS Framework for Mercury Bonding.

The remarkable chemical activity of metal-sulfur clusters lies in their unique spatial configuration associated with the abundant unsaturated-coordination nature of sulfur sites. Yet, the manipulation of sulfur sites normally requires direct contact with other metal atoms, which inevitably changes the state of the coordinated sulfur. Herein, we facilely construct a Mn-SnS framework by regulating the sulfur environment of the [SnS] cluster with metal ions.

Surface protection method for the magnetic core using covalent organic framework shells and its application in As(III) depth removal from acid wastewater.

FeO-based materials are widely used for magnetic separation from wastewater. However, they often suffer from Fe-leaching behavior under acidic conditions, decreasing their activity and limiting sustainable practical applications. In this study, covalent organic frameworks (COFs) were used as the shell to protect the FeO core, and the FeO@COF core-shell composites were synthesized for As(III) removal from acid wastewater.

Enhanced simultaneous absorption of NO and SO in oxidation-reduction-absorption process with a compounded system based on NaSO.

Oxidation of sulfite and competitive absorption existed in NaSO solution for simultaneous removal of NO and SO, inhibited the long-term high-efficiency when used for practical applications. A matching strategy was developed to solve these problems. Antioxidants combination was used to retard the oxidation of antioxidant and enhance inhibition of S(IV) (tetravalent sulfur) oxidation.

Strengthen the Affinity of Element Mercury on the Carbon-Based Material by Adjusting the Coordination Environment of Single-Site Manganese.

Mercury, as a highly poisonous pollutant, poses a severe threat to the global population. However, the removal of Hg can only be carried out at below 100 °C due to the weak binding of the adsorbent. Herein, a series of carbon-based materials with different coordination environments and atomic dispersion of single-site manganese were prepared, and their elemental mercury removal performance was systematically investigated.
