Reducing Aerosol Emissions by Decoupled Parameter Management during the CO Capture Process in a Multi-stage Circulation Absorber.

Aerosol emissions from the CO capture process have a significant impact in terms of solvent loss and environmental pollution. Here, we propose a novel approach with multi-stage circulation for CO capture and synergistic aerosol reduction, which divides the absorption section into three circulation stages and reduces aerosol emissions through decoupled operation of the three absorption sections and the management of solvent CO loadings. Experimental results show that with the decoupled management of the liquid-gas ratio and solvent temperature in absorption sections, the aerosol mass concentration at the outlet of the 3rd absorption section can be reduced by 25.

Tuning Ionic Liquid-Based Catalysts for CO Conversion into Quinazoline-2,4(1,3)-diones.

Carbon capture and storage (CCS) and carbon capture and utilization (CCU) are two kinds of strategies to reduce the CO concentration in the atmosphere, which is emitted from the burning of fossil fuels and leads to the greenhouse effect. With the unique properties of ionic liquids (ILs), such as low vapor pressures, tunable structures, high solubilities, and high thermal and chemical stabilities, they could be used as solvents and catalysts for CO capture and conversion into value-added chemicals. In this critical review, we mainly focus our attention on the tuning IL-based catalysts for CO conversion into quinazoline-2,4(1,3)-diones from -aminobenzonitriles during this decade (2012~2022).

Comparison of the Effectiveness and Safety of Vildagliptin Add-On to Metformin Versus Other Oral Dual Antidiabetes Agents in Patients with Type 2 Diabetes: The China Prospective Diabetes Study.

Introduction: The efficacy and safety of vildagliptin alone or with metformin is well established by randomized trials, but it is unknown whether it can be extrapolated to the real-world setting in Chinese patients with type 2 diabetes mellitus (T2DM). This study aimed to assess the effectiveness and safety of vildagliptin add-on to metformin versus dual oral antidiabetes drug (OAD), non-vildagliptin combination therapies in real-world Chinese patients with T2DM.

Methods: The China Prospective Diabetes Study was a post-marketing, prospective, multicenter, observational, real-world study conducted in 52 centers.

Highly Stretchable Strain Sensors Using an Electrospun Polyurethane Nanofiber/Graphene Composite.

A highly flexible and stretchable strain sensor has been prepared by coating chemical reduction of graphene oxide on electrospun polyurethane nanofiber mats. The sensor exhibits an ohmic behavior regardless of applied strains and the current monotonically increases with the increase of the tensile strain. The morphology and stability of electrospun polyurethane nanocomposite mats were also studied.

[Multi-centered, randomized controlled clinical study on Chinese medicine formula particles for hyperlipidaemia associated with highly active antiretroviral therapy].

Objective: To observe the effect and safety of Xiaozhi particles, integrated taohong Siwu tang and Erchen tang and Xuezhikang capsule in treating hyperlipidaemia (HLP) associated with highly active antiretroviral therapy (HAART).

Method: In the multi-centered, randomized controlled clinical study, 180 hyperlipidaemia associated with highly active antiretroviral therapy cases were divided into the treatment group treated by Xiaozhi particles, integrated Taohong Siwu tang and Erchen tang, and the control group treated by Xuezhikang capsule. The treatment course was 12 weeks.

[Inhibition of sulfite oxidation catalyzed by heavy metals in dual alkali flue gas desulfurization slurry].

Heavy metals accumulated in slurry of dual alkali flue gas desulfurization (FGD) present a significant catalysis to SO3(2-) oxidation, resulting in a waste of effective components for desulfurization. Na2S was adopted to precipitate heavy metal ions in FGD slurry, and the oxidation rate of SO3(2-) was obtained under different concentrations of heavy metal ions, to reveal the inhibition effect of Na2S on SO3(2-) oxidation catalyzed by heavy metal ions. Mn2+ showed a remarkable catalysis to SO3(-2) oxidation, as the initial oxidation rate of SO3(2-) was tripled to 0.
