In recent years, perovskite solar cells have drawn widespread attention. As an electrode material, fluorine-doped tin oxide (FTO) is widely used in various kinds of solar cells. However, the relatively low work function (WF) (~4.6 eV) limits its application. The potential barrier between the transparent conductive oxide (TCO) electrode and the hole transport layer (HTL) in inverted perovskite solar cells results in device performance decrease. In this paper, we propose a method to adjust WF of FTO by implanting zirconium ions into the FTO surface...

RELEVANCE: Benign prostatic hyperplasia (BPH) is one of the most common urologic diseases of males. In patients who failed drug therapy of lower urinary tract symptoms (LUTS) caused by BPH, the most important indication for surgery is the presence of infravesical obstruction (IVO). IVO is detected by pressure-flow studies and is characterized by high detrusor pressure with decreased urinary flow rate. The invasiveness and high cost of this investigation has stimulated a search for non-invasive techniques that could reliably characterize the presence of IVO secondary to BPH...

The feasibility of using Fe(0)/S2O8(2-) conditioning (zero valence iron (ZVI)/persulfate (ps)) integrated with horizontal electro-dewatering (HED) to improve the dewaterability of activated sludge (AS) was evaluated. The removal and migration of free and bound water in the ZVI/ps-HED process were determined, along with the organic matter migration between the solid and liquid phases of AS biosolids. Results showed that the optimum conditioning dosages were determined as 0.35 g ZVI/g dry solids (DS) and 0.15 g ps/g DS on the basis of capillary suction time variation...

Polyelectrolyte multilayers and layer-by-layer assemblies are susceptible to structural changes in response to ionic environment. By altering the salt type and ionic strength, structural changes can be induced by disruption of intrinsically bound ion pairs within the multilayer network via electrostatic screening. Notably, high salt concentrations have been used for the purposes of salt-annealing and self-healing of LbL assemblies with KBr, in particular, yielding a remarkably rapid response. However, to date, the structural and swelling effects of various monovalent ion species on the behavior of LbL assemblies remain unclear, including a quantitative view of ion content in the LbL assembly and thickness changes over a wide concentration window...

In this work, we introduced benzo[ghi]perylenetriimide (BPTI) derivatives including monomer and twisted dimer (t-BPTI) as an alternative electron transport layer (ETL) material to replace the commonly used PC61BM in inverted planar heterojunction perovskite solar cells. Moreover, the double ETL layer was applied in our perovskite solar cells with structure of glass/ITO/PEDOT:PSS/perovskite/BPTI/C60 or PDI-C4/BCP/Al. Use of a double ETL layer structure can effectively eliminate the leakage current. The devices with the t-BPTI/C60 double ETL layer yield an average power conversion efficiency of 10...

The implantable cuff electrode is an effective neuroprosthetic device in current nerve tissue engineering. However, biocompatibility and stability are still a serious dispute in terms of in vivo function and continuous monitoring. In this regard, assessing the host's biological response to biomaterials is one of the key factors of chronic implantation. In this article, we analyzed the peripheral nerve specific-biological responses to the application of multi-functional hydrogel-coated electrodes. The surface of the cuff electrode was modified using a multifunctional hydrogel composed of PEG hydrogel, cyclosporin A(CsA)-microsphere(MS) and electrodeposited PEDOT:PSS...

In this research, a haptacyclic carbazole-based dithienocyclopentacarbazole (DTCC) ladder-type structure was formylated to couple with two 1,1-dicyanomethylene-3-indanone (IC) moieties, forming a new non-fullerene acceptor DTCCIC-C17 using a bulky branched 1-octylnonayl side chain at the nitrogen of the embedded carbazole and four 4-octylphenyl groups at the sp3-carbon bridges. The rigid and coplanar main-chain backbone of DTCC core provides a broad light-absorbing window and a higher-lying LUMO energy level, while the bulky flanked side chains to reduce intermolecular interactions make DTCCIC-C17 amorphous with excellent solution processability...

Over several decades, natural polysaccharides (PSs) have been actively exploited for their wide bioactivities. So far, many PS-related reviews have been published; however, none focused on the delivery of bioactive PSs as therapeutic molecules. Herein, we summarized and discussed general pharmacokinetic properties of PSs and drug delivery systems (DDSs) developed for them, together with the challenges and prospects. Overall, most bioactive PSs suffer from undesirable pharmacokinetic attributes, which negatively affect their efficacy and clinical use...

For planar structured organic-inorganic hybrid perovskite solar cells (PerSCs) with PEDOT:PSS hole transportation layer, the open-circuit voltage (Voc) of the device is limited to be about 1.0 V, resulting inferior performance in comparison with TiO2 based planar counterparts. Therefore, increasing Voc of the PEDOT:PSS based planar device is an important way to enhance the efficiency of the PerSCs. Herein, we demonstrate a novel approach of formation perovskite film by slow-growing from lead acetate precursor via one-step spin-coating process without thermal annealing process...

Stress among adolescents is a widely discussed topic. This study examined stress levels, stress-related factors, and the possible correlation between stress and depression in adolescents at high schools in Thailand. The survey measuring stress (T-PSS-10) and depression (PHQ-9) was conducted on 15- to 19-year-olds in three public urban schools ( n = 168, response rate 90%). The data were analysed with descriptive statistics followed by the analysis of the background factors and their associations with adolescent stress levels using χ(2) tests, or Pearson's correlation coefficient, while the mean differences between groups were tested with a T-test or analysis of variance...

Primary Sjögren's syndrome (pSS) is characterized by a panel of autoantibodies, while it is not clear whether B cells and autoantibodies play an essential role in pathogenesis of the disease. Here, we report a novel mouse model for pSS which is induced by immunization with the Ro60_316-335 peptide containing a predominant T cell epitope. After immunization, mice developed several symptoms mimicking pSS, including a decreased secretion of tears, lymphocytic infiltration into the lacrimal glands, autoantibodies, and increased levels of inflammatory cytokines...

Development of antimicrobial photodynamic therapy (aPDT) is highly dependent on the development of suitable photosensitizers (PS): ideally affinity of PS towards bacterial cells should be much higher than towards mammalian cells. Cationic charge of PS may lead to selective binding of PS to bacteria mediated by electrostatic interaction; however, the photodynamic outcome is highly dependent on the lipophilicity of PS. Herein we report the aPDT effect of silicon(IV)phthalocyanine derivatives bearing four positive charges and methyl, phenyl or naphthyl substituents on the periphery of the macrocycle...

Hydroxychloroquine inhibits systemic inflammation and autophagy and may thus have antineoplastic effects [1]. We investigated the effect of hydroxychloroquine on cancer risk in patients with primary Sjögren syndrome(pSS). We used the Taiwan National Health Insurance Database to compare cancer incidence between incident pSS patients with or without at least 6-month hydroxychloroquine use within a 1- or 3-year period. Propensity score matched landmark analysis was used. We included 4194 alive patients without cancer 1 year after pSS diagnosis from 2000 through 2005...

Four tetra-dithienylethene (DTE) substituted porphyrins, the free base 1H₂ and three metal derivatives (1Zn, 1Co, 1Ni), were synthesized and studied. These dyads, in which the DTE units are connected to the porphyrin's meso positions via a meta-phenyl spacer, exhibit reversible photochromic properties in all cases with conversion to the PSS up to 88%, as confirmed by absorption and NMR spectroscopies. Compounds 1H₂ and 1Zn are fluorescent in solution and display a red emission. Upon irradiation with UV light to trigger the closing of the DTEs, the fluorescence of both the free base and zinc porphyrin was very efficiently quenched in solution...
