The aggregated H₂O molecules tend to produce a hydrogen-terminated surface, and then generate barium dissociation of the barium oxide (BaO) surface. The dissociated barium of the surface, driven by the high affinity of H₂O to the surface, contributes to a reduction in basicity, which may gradually cause the reduction of CO₂ adsorption performance.

Ce³⁺ was inserted into interstitial positions of g-C₃N₄ by coordinating to N atoms, which enhanced the S_BET, decreased the bandgap energy, and increased the separation efficiency of electrons and holes, thus leading to enhanced photocatalytic activity.

The effect of ADN additive on EC electrolyte of EDLC was confirmed by various chemical and electrochemical performances. When adding ADN (30%), the capacitance of the capacitor had a value similar to that when using the commercial ACN electrolyte of EDLCs (about 40 F/g). Among the studied electrolytes, 70% EC/30% ADN electrolyte solution gave the best electrochemical properties, such as specific capacitance (44.6 F/g at a scan rate of 5 mV/s) and cycle ability (98% retention of initial value after 2000 cycles).

A hard carbon-coated natural graphite is proposed for use in high-power lithium-ion capacitors. By using polyacrylonitrile precursor, hard carbon is uniformly coated on the surface of natural graphite with the thickness of 20–30 nm. The coating layer on natural graphite is mainly responsible for the improved cycle life and excellent rate capability of LIC full cell.

Under excitation at 980 nm, the UC intensities of KGd_0.7(WO₄)₂:Ho_0.1Yb_0.2 and KGd_0.5(WO₄)₂Ho_0.05Yb_0.45 particles exhibited yellow emissions based on strong 550- and 655-nm emission bands in the green and red regions, respectively, which in turn were assigned to the ⁴S₂/⁵F₄→⁵I₈ and ⁵F₅→⁵I₈ transitions, respectively.

The diameter dependence of 20 different drugs on carbon nanotube (CNT) size in drug delivery was explored via molecular dynamics simulation. The changes in the gyration radius (R_g) of the CNTs and drugs were calculated, and a linear correlation was obtained.

The inverted change of pCa oscillation to pH oscillation at lower pH in the BrO₃⁻–SO₃²⁻–Fe(CN)₆⁴⁻ system introduced Ca–EDTA was especially studied.

IC chromatogram of oyster (Crassostrea gigas, culture, Tong-yeong).

We measure the probability of the molecular junction formation with different linker groups via the STM-BJ technique. The junction formation probability of amine, methylsulfides, and thiol is found to be in the sequence SH > SMe > NH₂.

Longitudinal observations of peptide losses during sample solution storage in an autosampler vial.

Core/shell structural carbon nitride/TiO₂ nanofiber heterojunction photocatalyst exhibits the enhanced electron-hole separation efficiency and rhodamine B degradation ability under simulated solar light irradiation.

A new triterpene glycoside, named akeqintoside E, 3 αα,23αα-dihydroxy-30-norolean-12,20(29)-dien-28-oic acid 28-O-αα-L-rhamnopyranosyl-(1→4)-O-ββ-D-glucopyranosyl-(1→6)-O-ββ-D-glucopyranosyl ester (1), along with seven known compounds, akeboside St_h (2), begoniifolide A (3), akebia saponin P_J2 (4), 3ββ-[(O-GlcUA-(1–3)-O-[Rha-(1–2)]-Ara)oxy]olean-12-en-28-oic acid O-Rha-(1–4)-Glc-(1–6)-Glc ester (5), kalopanax saponin D (6), 3ββ-[(O-GlcUA-(1–3)-Ara)oxy]olean-12-en-28-oic acid O-Rha-(1–4)-Glc-(1–6)-Glc ester (7), and akebia saponin P_J3 (8), was isolated from Akebia quinata. The structures of the compounds were identified on the basis of 1D and 2D NMR, including ¹H– ¹H COSY, HSQC, HMBC, and NOESY spectroscopic analyses.

We report a solid-phase synthesis of 2,4-diamino-1,3,5-triazines, starting from 2,4-dichloro-1,3,5-triazine captured by resin-bound amines followed by amination and acidic mild cleavage. The derivatives of 22 diamino-1,3,5-triazine compounds were prepared in high purity without extensive reaction conditions.
