A series of new n-type copolymers based on perylene diimide (PDI) or naphthalene (NDI) and phenothiazine (PTZ) with different side chain length molecular weight have been designed synthesized by Pd-catalyzed Suzuki coupling polymerization without phase-transfer catalyst Aliquat 336. The effects main chain, the thermal, optical, electronic, charge transport properties polymers investigated. 336 improves as well reduces polydispersity index polymers. All exhibit a broad absorption extending...
For AlGaN-based near ultraviolet laser diodes (UVA LDs) with emission wavelength below 365 nm, there is no such suitable substrate for homoepitaxy to the required AlGaN films. In this study, we proposed a two-step growth (TSG) method of thick Al0.2Ga0.8N layer grown on sapphire sputtered AlN nucleation layer. The influence rate and V/III ratio mode an has been studied in detail. It found that films exhibit larger island size lower density low during 3D stage, which can effectively relax...
It has been argued that Working Memory Training (WMT) the potential to improve emotional regulation. In this study, we investigated whether 20 days of WMT improved general emotion regulation in healthy participants using resting high-frequency heart rate variability (HF-HRV) as a physiological indicator regulation, and examined its maintenance effect three months later. The analysis linear mixed-effects (LME) model revealed after completing WMT, there was significant improvement individual's...
Main-group phthalocyanines are an emerging class of organic semiconductors with versatile charge carriers in field-effect transistors. In this review, overview is provided on the synthesis these building blocks and device performances.
Two new low-bandgap, conjugated donor (D)−acceptor (A) copolymers of porphyrin with 2,3-bis(4-trifluoromethylphenyl)pyrido[3,4-b]pyrazine (P1) and perylene diimide (P2) were synthesized by Sonogashira coupling polymerization compared porphyrin−dithienothiophene D−D copolymer (P3). All these polymers possess good thermal stability decomposition temperatures over 300 °C. Polymers P1 P2 in films exhibit strong absorption near-IR (820−950 nm) optical bandgaps as low 1.15 eV; their Q-bands red...
The lamination method, an effective way to fabricate multilayer devices, is successfully applied in the fabrication of top-gate organic thin-film transitors (OTFTs), especially solution-processed devices. fabricated devices exhibit both high performance and good stability.
In this study, poly(lactic acid) (PLA)/starch blends were prepared through reactive melt blending by using PLA and starch as raw materials vegetable oil polyols, polyethylene glycol (PEG), citric acid (CA) additives. The effects of CA PEG on the toughness PLA/starch analyzed a mechanical performance test, scanning electron microscope analysis, differential calorimetry, Fourier-transform infrared spectroscopy, X-ray diffraction, rheological hydrophilicity test. Results showed that elongation...
A series of polylactic acid (PLA)/polyethylene glycol (PEG) blends was prepared by melt blending using PEG as a plasticizer to address the disadvantages PLA brittleness. can weaken intermolecular chain interactions and improve its processing properties. PLA-grafted maleic anhydride (GPLA) reactively blended with PLA/PEG obtain high tenacity PLA/PEG/GPLA blend. GPLA grafting diisopropyl peroxide initiator graft.

Working memory training (WMT) has shown potential benefits in emotion regulation (ER), mainly terms of improved ability to downregulate negative emotions cognitive reappraisal. However, the goal reappraisal can be not only reduce but also increase emotion. It is clear what effect WMT on upregulation In current study, we conducted a 20-day with participants explore effects down- and followed for 3 months after examine persistent training. Our results suggest that group their regulate both...
