Ionic liquid assisted construction of synergistic modulated multiphase hybrid composites for boosting electrochemical energy storage.

The unique structure and strong interaction of multiphase hybrid materials have garnered significant attention as prospective candidates for electrode materials in the realm of energy storage. The present study presents a rational design of a functional NiSe-CoSe/N, B double-doped carbon hybrid composite (NCS/C), resulting in the emergence of various novel cooperative regulatory mechanisms involving: (i) the heterogeneous structure of NiSe and CoSe generates built-in electric fields to increase electron mobility; (ii) the incorporation of polyatomic double-doped carbon (N, and B) expedites electron transfer rate; intriguingly, (iii) ionic liquids not only serve as polyatomic dopants in the reaction system but also influence the microstructure of the composite. Benefiting from these synergistic effects, the NCS/C hybrid exhibits remarkable charge storage capacity and rapid electrochemical kinetics, driven by its multi-fold hollow structure and multicomponent cooperative modulation.

Mesoporous Silica Supported Hydrophilic Ionic Liquid Gel Microspheres for Solvent-Free Deep Oxidative Desulfurization.

Solvent-free oxidative desulfurization can avoid environmental pollution caused by organic solvents as well as prevent loss of fuel during the oil-water separation process. In this work, first, hydrophilic ionic liquid gel microspheres with [BMIM]BF and PHEMA as the dispersion medium and gel network, respectively, were successfully prepared by using mesoporous silica microspheres as a supporting skeleton capable of stabilizing the gel through an anchoring effect, and then the catalyst [BMIM]PW and oxidant HO were incorporated into the gel microspheres to construct a liquid compartment microreactor for deep desulfurization. The prepared microreactor (SiO@[BMIM]PW/ILG-microspheres) has excellent extraction-catalytic capacity and exhibited ∼100% desulfurization ratio for a model oil of -heptane with 500 ppm of DBT at 60 °C for 3 h without solvents.

Positron emission tomographic studies of the association between atherogenesis and aortitis among psoriatic patients.

Introduction: There is increased interest in the use of positron emission tomography (PET) in psoriatic patients. We used PET induced with tracer fluorine-18 (F) fluorodeoxyglucose (FDG) to study the association between the process of early-atherogenesis (eAg) and aortitis by quantifying enhanced aortic vascular inflammation along with calculation of total coronary plaque load (TCPL) and non-calcified atherosclerotic plaque load (NcAPL). In order to study the utility of aortitis in capturing eAg, we also assessed luminal stenosis atherosclerosis (LSA) and high-risk coronary plaques (HrCP).

Ultrathin 1T-MoS Nanoplates Induced by Quaternary Ammonium-Type Ionic Liquids on Polypyrrole/Graphene Oxide Nanosheets and Its Irreversible Crystal Phase Transition During Electrocatalytic Nitrogen Reduction.

Ultrathin nanoplates of metastable 1T-MoS have been successfully stabilized and uniformly distributed on the surface of -butyl triethyl ammonium bromide functionalized polypyrrole/graphene oxide (BTAB/PPy/GO) by a very simple hydrothermal method. BTAB as a typical kind of quaternary ammonium-type ionic liquids (ILs) played a crucial role in the formation of the obtained 1T-MoS/BTAB/PPy/GO. It was covalently linked with PPy/GO and arranged in a highly ordered order at the solid-liquid interface of PPy/GO and HO due to Coulombic interactions and other intermolecular interactions, which would induce and stabilize ultrathin 1T-MoS nanoplates by morphosynthesis.

Ultrathin NiS/Ni(OH) Nanosheets Filled within Ammonium Polyacrylate-Functionalized Polypyrrole Nanotubes as an Unique Nanoconfined System for Nonenzymatic Glucose Sensors.

Ultrathin two-dimensional NiS/Ni(OH) nanosheets (NiS/Ni(OH) NSs) were successfully filled within the hollow interiors of ammonium polyacrylate-functionalized polypyrrole nanotubes (NHPA/PPyNTs) by a simple solvothermal method. This kind of novel hierarchical nanostructures with typical structural features of a nanoconfined system, denoted by NiS/Ni(OH)/NHPA/PPyNTs, were prepared by two main sections: polyacrylic acid (PAA) was first polymerized on PPyNTs containing vinyl groups, and the obtained PAA/PPyNTs exhibited a typical Janus structure, whose external surface was covered with carboxyl groups and the internal surface was still covered with PPy chains; second, Ni ions as a precursor were facilely combined with -NH- segments in PPy chains by the coordination interaction under the solvothermal environment; therefore, NiS/Ni(OH) NSs (<1 nm) were well distributed on the internal surface of NHPA/PPyNTs by the in situ growth. Because of the synergistic effects of ionizable NHPA, PPy with good conductivity, NiS and Ni(OH) with electrocatalytical activity, as well as the nanoconfinement effect, the obtained NiS/Ni(OH)@NHPA/PPyNTs exhibited excellent electrocatalytic performance for detecting glucose.
