Aqueous high-energy-density capacitor with 2 V output voltage for alternating current line filtering.

High-energy-density aqueous filtering capacitors are essential for the conversion of alternating current to direct current in contemporary integrated circuits. Yet their energy density is limited by the 1.23 V decomposition voltage of water.

3,4-Dichlorophenylacetic acid acts as an auxin analog and induces beneficial effects in various crops.

Auxins and their analogs are widely used to promote root growth, flower and fruit development, and yield in crops. The action characteristics and application scope of various auxins are different. To overcome the limitations of existing auxins, expand the scope of applications, and reduce side effects, it is necessary to screen new auxin analogs.

The co-inoculation of Trichoderma viridis and Bacillus subtilis improved the aerobic composting efficiency and degradation of lignocellulose.

The aim of this study was to reveal the mechanism by which co-inoculation with both Trichoderma viridis and Bacillus subtilis improved the efficiency of composting and degradation of lignocellulose in agricultural waste. The results showed that co-inoculation with Trichoderma and Bacillus increased abundance of Bacteroidota to promote the maturation 7 days in advance. Galbibacter may be a potential marker of co-inoculation composting efficiency compost.

Active Sulfur-Host Material VS with Surface Defect Engineering: Intercalation-Conversion Hybrid Cathode Boosting Electrochemical Performance of Li-S Batteries.

Transition-metal sulfides as late-model electrocatalysts usually remain inactive in lithium-sulfur (Li-S) batteries in spite of their advantages to accelerate the rapid conversion of lithium polysulfides (LiPSs). Herein, a series of cobalt-doped vanadium tetrasulfide/reduced graphene oxide (%Co-VS/rGO) composites with an ultrathin layered structure as an active sulfur-host material are prepared by a one-pot hydrothermal method. The well-designed two-dimensional ultrathin 3%Co-VS/rGO with heteroatom architecture defects (defect of Co-doping and defect of S-vacancies) can significantly improve the adsorption ability on LiPSs, the electrocatalytic activity in the LiS potentiostatic deposition, and the active sulfur reduction/oxidation conversion reactions and greatly boost the electrochemical performances of Li-S batteries.

Cu O-Catalyzed Conversion of Benzyl Alcohols Into Aromatic Nitriles via the Complete Cleavage of the C≡N Triple Bond in the Cyanide Anion.

Nitrogen transfer from cyanide anion to an aldehyde is emerging as a promising method for the synthesis of aromatic nitriles. However, this method still suffers from a disadvantage that a use of stoichiometric Cu(II) or Cu(I) salts is required to enable the reaction. As we report herein, we overcame this drawback and developed a catalytic method for nitrogen transfer from cyanide anion to an alcohol via the complete cleavage of the C≡N triple bond using phen/Cu O as the catalyst.

Light driven molecular lock comprises a Ru(bpy)(hpip) complex and cucurbit[8]uril.

Here, complex 1 ([Ru(bpy)(hpip)]-MV) and CB[8] can form a stable 1 : 1 inclusion complex in aqueous solution, resembling a U-shaped conformation. Upon light irradiation, two complex 1 were reversibly locked through the formation of a MV˙ radical dimer that is stabilized in the cavity of CB[8] with Ru complexes as blockers, in which complex 1 was transformed from a U-shaped conformation to a interlocked complex. This study provided a feasible strategy for the fabrication of a photo-driven supramolecular machine resembling a "lock".

Poly[bis-[μ(3)-2-(1H-tetra-zol-1-yl)acetato]cadmium(II)].

In the title compound, [Cd(C(3)H(3)N(4)O(2))(2)](n), the Cd(II) ion, located on a twofold rotation axis, is six-coordinated by two N atoms [Cd-N = 2.368 (2) Å] and four O atoms [Cd-O = 2.300 (1) and 2.

Dichlorido(2,9-diprop-oxy-1,10-phenanthroline-κN,N')cadmium(II).

In the title complex, [CdCl(2)(C(18)H(20)N(2)O(2))], the Cd(II) ion is coordinated by two N atoms from a bis-chelating 2,9-diprop-oxy-1,10-phenanthroline ligand and two Cl atoms in a distorted tetra-hedral environment. The two Cd-Cl bond distances are significantly different from each other and the N-Cd-N bond angle is acute. In the crystal structure, there are π-π stacking inter-actions between symmetry-related phenanthroline ring systems, with a centroid-centroid distance of 3.

(2,9-Dieth-oxy-1,10-phenanthroline-κN,N')bis-(thio-cyanato-κN)cobalt(II).

In the title complex, [Co(NCS)(2)(C(16)H(16)N(2)O(2))], the Co(II) ion is coordinated by two N atoms from one 2,9-dieth-oxy-1,10-phenanthroline ligand and two N atoms from two different thio-cyanate ligands in a distorted tetra-hedral environment. The Co-N bonds involving the thio-cyanate ligands are significantly shorter than the other two Co-N bonds. The atoms of one of the eth-oxy groups are essentially coplanar with the phenanthroline ring [N=C-O-C = 178.

catena-Poly[[(2,9-dieth-oxy-1,10-phen-anthroline-κN,N')cadmium(II)]-di-μ-dicyan-amido-κN:N].

In the title polymer, [Cd(C(2)N(3))(2)(C(16)H(16)N(2)O(2))](n), the Cd(II) ion is coordinated by two N atoms from one 2,9-dieth-oxy-1,10-phenanthroline mol-ecule and four N atoms from four symmetry-related dicyanamide ions in a distorted octa-hedral geometry. In the 2,9-dieth-oxy-1,10-phenanthroline ligand, the O and C atoms of the eth-oxy groups are located almost in the plane defined by the phenanthroline ring system. Two dicyanamide ions bridge two Cd(II) ions, which are located on a twofold axis, forming a one-dimensional zigzag chain along the [001] direction.
