Synthesis of Conjugated Polymers for Organic Solar Cell Applications

typically based on n-type metal oxides, our device is solutionprocessed at room temperature, enabling easy processibility over a large area. Accordingly, the approach is fully amenable to highthroughput roll-to-roll manufacturing techniques, may be used to fabricate vacuum-deposition-free PSCs of large area, and find practical applications in future mass production. Moreover, our discovery overturns a well-accepted belief (the inferior performance of inverted PSCs) and clearly shows that the characteristics of high performance, improved stability and ease of use can be integrated into a single device, as long as the devices are optimized, both optically and electrically, by means of a meticulously designed device structure. We also anticipate that our findings will catalyse the development of new device structures and may move the efficiency of devices towards the goal of 10% for various material systems. Previously, we reported that PFN can be incorporated into polymer light-emitting devices (PLEDs) to enhance electron injection from high-work-function metals such as aluminium (work function w of 4.3 eV) 22,23 and has thus been used to realize high-efficiency, air-stable PLEDs 24 . Furthermore, we also found that efficient electron injection can be obtained even in the most noble metals with extremely high work functions, such as gold (w ¼ 5.2 eV), by lowering the effective work function (for example lowering w in gold by 1.0 eV), which has previously been ascribed to the formation of a strong interface dipole 25 .

Aggregation-induced emission: phenomenon, mechanism and applications.

This paper proposes a flexible double-sided attached microwave sensor film for real-time measurement of the liquid dielectric constant, and proposes a nested-complementary split ring resonator（NCSRR）structure with high sensitivity and quality factor values that is based on the structure evolution of a complementary split ring resonator（CSRR）. The sensor films are composed of a ground film with an NCSRR structure and a U-shaped microstrip line film. By taking a borosilicate glass beaker and a polypropylene beaker as examples, two types of microwave sensors are formed by attaching films to both sides of the beakers. Lubricating oil with 0%-25% water content is added to the beakers separately, and the dielectric constants of the mixture are characterized nondestructively by the transmission coefficient (S21) of the device. According to the mathematical model established from the measurement results, the resonant frequencies of both sensors are linearly and negatively correlated with the dielectric constant of the liquid to be measured, which proves that the sensor film can be attached to a substrate with arbitrary curvature to form a microwave resonant sensor.

With the increase in awareness of environmental protection and the shortage of oil resources, bio-based polyurethane has attracted increasing attention due to its ecological friendliness, low cost and easy degradation. In this paper, using Eugenol (Eug) derived from plant essential oils as the raw resource, syringyl ethanol (Syol) was prepared, and three monomers were obtained by the reaction of the Eug or Syol with Hexamethylene diisocyanate (HDI)or 4,4′-methylene di (phenyl isocyanate) (MDI), respectively. Then, three novel bio-based polyurethanes, P(Eug-HDI), P(Syol-HDI) and P(Syol-MDI), were synthesized by olefin metathesis polymerization. The effects of the catalyst type, reaction solvent, reaction temperature, reaction time, molar ratio of catalyst dosage and metal salts on the Eug-HDI olefin metathesis polymerization were investigated in detail. Under the optimal conditions, the yield reached 64.7%. It is worth noting that the addition of metal Ni salts could significantly promote the polymerization, in which NiI2 could increase the yield to 86.6%. Furthermore, the thermal decomposition behaviors of these bio-based polyurethanes were explored by DSC and variable temperature infrared spectroscopy. The test results showed that P(Eug-HDI) had a reversible thermal decomposition and a certain self-healing performance. This paper provided a new method for the preparation of bio-based polyurethane.

Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy is a recently identified recurrent meningoencephalomyelitis with GFAP immunoglobulin G presence in the serum or cerebrospinal fluid (CSF) as a specific biomarker. GFAP astrocytopathy is closely associated with the occurrence of some tumors and often coexists with other antibodies, such as the N-methyl-D-aspartate receptor and aquaporin-4 antibodies. However, GFAP astrocytopathy complicated by central nervous system infection is rare.Here, we present the case of a patient admitted to a local hospital due to a prominent fever and cough. The patient had a 1-month history of headaches before admission that were not considered serious at the time. Metagenomic next-generation sequencing (mNGS) of bronchoalveolar lavage fluid revealed a high sequence number of Legionella pneumophila and a few mycobacteria. His cough and fever improved significantly after antibiotic treatment. Still, a slight headache remained. Subsequently, his condition worsened, and he visited our hospital with a disturbance of consciousness. Mycobacterium tuberculosis was detected with mNGS of the CSF, while the CSF and serum were also positive for GFAP antibodies. Following anti-tuberculosis and steroid therapy, the patient's symptoms improved, and he tested negative for the GFAP antibody.This is the first reported case of GFAP astrocytopathy complicated by tuberculous meningoencephalitis. Due to overlaps in the clinical manifestations of the two diseases, GFAP astrocytopathy is sometimes misdiagnosed as tuberculous meningoencephalitis. Therefore, in addition to ensuring careful identification of the two diseases, clinicians need to be aware of their possible co-existence.
