Three new species of Chresmodidae are described. They belong to two different genera： Chresmoda multinervis sp. nov., Chresmoda shihi sp. nov. and Jurachresmoda sanyica sp. nov.. A study of the forewing venation is provided. Longitudinal veins are mostly parallel; costal area is broad at the basal and narrowing distally; ScP is probably extending close to the wing apex; R is parallel at length to ScP; MA is running close to R, with two long parallel branches; MA branched-off basally; while MP is not branched until the middle of the wing. However, the important basal part of MP and CuP is poorly preserved. In addition, unique fringing hairs on the mid legs of C. shihi sp. nov. and J. sanyica sp. nov. are described and compared with Jurachresmoda gaskelli zhang, Ren and Shih, 2008.

We investigated the effects of pulsed current (PC) and direct current (DC) driving modes on the stability of organic light-emitting diodes with and without hole-injection layers (HILs).Two different HIL materials were used:copper phthalocyanine (CuPc) and 4,4',4″-tris(3-methylphenylphenylamino)triphenylamine (m-MDTATA).It was found that the half-lives of devices using PC driving modes were different from those of comparable devices using DC driving *** the devices without HILs,with CuPc HILs and with MTDATA HILs,the half-lives of the devices were changed by factors of 1.91,1.41 and 0.86,respectively,when operated in PC rather than DC driving *** analysis of the electrical characteristics of the corresponding hole-only devices showed that the number of holes injected into devices was greatly reduced by inserting an m-MTDATA layer compared with other *** results indicate that different ratios of injected electrons and holes can be obtained in these ***,these ratios play a dominant role in the dependence of the stability of the device on the driving mode.

A new multi-functional penta-carbazole/benzophenone hybrid compound 5CzBP was designed and synthesized through a simple one-step catalyst-free C--N coupling reaction by using 2,3,4,5,6-pentafluorobenzophenone and carbazole as starting materials. 5CzBP is very soluble in tetrahydro- furan （THF）, which brings an environmentally friendly device fabrication for solution-processed OLEDs instead of most widely used chlorinated solvents when 5CzBP is employed as the bulk-phase of organic host or non-doped emitter in the emissive layer. 5CzBP exhibits thermally activated delayed fluo- rescence （TADF） characteristic with relatively high triplet energy of 2.60 eV and a low bEsT of 0.01 eV. By using the new TADF material as organic host for another green TADF emitter, maximum external quantum efficiency （EQE） of 12.5% has been achieved in simple solution-processed OLED device. Besides, a maximum EQE of 8.9% and 5.7% was further obtained in TADF devices based on 5CzBP as dopant and non-doped emitter, respectively. The simultane- ously acting as efficient TADF host and non-doped TADF emitter provides the potential guidance of the future simple single-layer two-color white OLEDs based on low-cost pure organic TADF materials.

Objective: Short-term effects of 0.02%/0.04% atropine sulfate eye drops on choroidal thickness in myopic children using optical coherence tomography angiography. Methods: Thirty-two children aged 6 - 12 years were selected and divided into 22 cases and 44 eyes in the 0.02%/0.04% atropine sulfate eye drops observation group and 10 cases and 20 eyes in the control group. The linear regression equation was used to evaluate the correlation among the spherical equivalent, the axial length and the subfoveal choroidal thickness, moreover, used to evaluate the correlation between the baseline and 6 months later. Independent samples T-test was used to detect whether there was any statistical difference between the nasal 1 mm subfoveal choroidal thickness and the temporal 1 mm subfoveal choroidal, meanwhile, compared with the baseline and 6 months later. P Results: After 6 months follow-up, the axial length increased by 0.067 ± 0.199 mm in the atropine group, 0.201 ± 0.081 mm in the control group (P Conclusions: 1) 0.02%/0.04% atropine sulfate eye drops can delay the growth of axial length and spherical equivalent;2) 0.02%/0.04% atropine sulfate eye drops can thicken the choroid, and the thickness of the nasal side 1mm is the same as that of the temporal side 1 mm;3) At baseline, the subfoveal choroidal thickness has no significant correlation with the axial length and spherical equivalent;4) After 6 months, changes in axial length and spherical equivalent were negatively correlated with changes in subfoveal choroidal thickness.
