Persistent genital arousal disorder (PGAD) and genito-pelvic dysesthesia (GPD) jointly known as persistent genital arousal disorder/genito-pelvic dysesthesia syndrome (PGAD/GPD) , which was a unique disorder characterized by spontaneous or secondary genital arousal and dysesthesia in the genital and pelvic areas discovered abroad in recent years. In addition, no relevant reports on PGAD/GPD have been found in CNKI, WanFang Data, and VIP. Discovery of posture secret (DPS) is a manual therapy technique with the 4R principle as the core developed from the integration of various mainstream posture correction techniques in the world, which has unique curative effect on improving musculoskeletal pain and abnormal posture. This article reports a domestic case of complete remission of symptoms of PGAD/GPD treated with DPS, and reviews relevant foreign literature on PGAD/GPD, in order to raise the attention of domestic peers.

Organic light-emitting diodes (OLEDs) are widely recognized as the forefront technology for displays and lighting technology. Now, the global OLED market is nearly mature, driven by the rising demand for superior displays in smartphones. In recent years, numerous strategies have been introduced and demonstrated to optimize the hole injection layer to further enhance the efficiency of OLEDs. In this paper, different methods of optimizing the hole injection layer were elucidated, including using a suitable hole injection material to minimize the hole injection barrier and match the energy level with the emission layer, exploring new preparation methods to optimize the structure of hole injection layer, and so on. Meanwhile, this article can help people to understand the current research progress and the challenges still faced in relation to the hole injection layer in OLEDs, providing future research directions to enhance the properties of OLEDs.

Summary: Transition metal sulfides show excellent performance in an aqueous supercapacitor. However, all‐solid‐state supercapacitors are attracting more and more interest because of thinner, lighter, and more flexible. Binary sulfides Ni3Co6S8 nanowire arrays (NCS) are directly grown on a nitrogen‐doped carbon foam (NCF) through hydrothermal reaction, which is applied as a binder‐free electrode for all‐solid‐state supercapacitor. The unique needlelike structure assembled by nanosheet effectively increases the utilization efficiency of active materials and promotes electrochemical performance. The NCS‐NCF electrode shows promising application potential for wearable electronic devices due to the flexibility of NCF. A high‐specific capacitance of 243 mAh g−1is delivered by NCS‐NCF electrode, which also exhibits good rate behavior along with outstanding cycle stability. The NCS‐NCF electrode (positive electrode) and NCF electrode (negative electrode) are employed to assemble asymmetric all‐solid‐state supercapacitor. When the high power density is 675 W kg−1, the energy density of supercapacitor reaches the maximum of 28.31 Wh kg−1. The specific capacitance of supercapacitors could maintain 84%, after 10 000 cycles of galvanostatic charge and discharge under 4 A g−1, indicating the potential application of NCS‐NCF electrode as an excellent supercapacitor electrode material in flexible, wearable energy storage systems.

The four 18-tungsto-2-arsenates(III) [MII(H2O)(TiIVO)2(α-AsIIIW9O33)2]12- [M = Co (CoTi2), Ni (NiTi2), Cu (CuTi2), Zn (ZnTi2)] were rationally synthesized by treating the respective divalent metal ions with the monolacunary, dititanium(IV)-containing polyanion precursor [(TiIVO)2(α-AsIIIW9O33)2]14- (Ti2) in aqueous solution. All four polyanions are isostructural and correspond to dimers with two Ti4+ and one M2+ ion sandwiched between two [α-AsIIIW9O33]9- units. The compounds were characterized in the solid state by single-crystal XRD, infrared spectroscopy, thermogravimetric analysis, and elemental analysis and in solution by UV/Vis and NMR spectroscopy as well as electrochemistry. Variable-temperature magnetic susceptibility and variable-field magnetization characterization of the paramagnetic derivatives indicate antiferromagnetic interactions between nearest neighbors in the solid state. The resolved hyperfine structure obtained from multifrequency EPR measurements on CuTi2 (which exhibits a Jahn-Teller effect) in the solid state lead us to assign the ground state mainly to the Cu d x²- y² orbital. Despite the fact that the four polyanions are isostructural and have the same overall negative charge, the cyclic voltammetric patterns featuring their chemically reversible reduction waves display distinct features. Electrocatalytic studies demonstrate that the activities of the polyanions towards nitrate reduction are strikingly influenced by the nature of the substituent metal ion. [ABSTRACT FROM AUTHOR]

The first examples of dimeric, di-PtII-containing heteropolytungstates are reported. The two isomeric di-platinum(II)-containing 22-tungsto-2-phosphates [ anti-PtII2( α-PW11O39)2]10− ( 1 a) and [ syn-PtII2( α-PW11O39)2]10− ( 2 a) were synthesized in aqueous pH 3.5 medium using one-pot procedures. Polyanions 1 a and 2 a contain a core comprising two face-on PtO4 units, with a Pt⋅⋅⋅Pt distance of 2.9-3 Å. Both polyanions were investigated by single-crystal XRD, IR, TGA, UV/Vis, 31P NMR, ESI-MS, CID-MS/MS, electrochemistry, and DFT. On the basis of DFT and electrochemistry, we demonstrated that the {Pt2II} moiety in 1 a and 2 a can undergo fully reversible two-electron oxidation to {Pt2III}, accompanied by formation of a single Pt−Pt bond. Hence we have discovered the novel subclass of PtIII-containing heteropolytungstates. [ABSTRACT FROM AUTHOR]
