Compared with the traditional Mo back electrode of Cu2ZnSn(S,Se)4 (CZTSSe) solar cells, the transparent and conductive electrode of fluorine-doped tin oxide (FTO) has the advantages of low lattice mismatch with the CZTSSe absorber, earth-abundant composition, transparency, and advanced applications in building integrated photovoltaics. Hence, the research of bifacial FTO/CZTSSe thin film solar cells has attracted more and more attention. However, the poor interface contact between n-type FTO/p-type CZTSSe prevents the improvement of power conversion efficiency (PCE) of CZTSSe thin film solar cells deposited on the FTO substrate. Therefore, back contact interface modification is an effective strategy to promote the performance of the FTO/CZTSSe solar cells. Here, we choose the solution-processed MoO3 as the interface layer to modify the interface of FTO/(Cu,Ag)2ZnSn(S,Se)4 (CAZTSSe), and systematically investigate the effects of the thickness of MoO3 interface layer on the performance of FTO/MoO3/CAZTSSe solar cells. It is found that the optimal thickness of the solution-deposited MoO3 interface layer is 30 nm. As a result, kesterite solar cells on the FTO substrate achieve a front-side PCE of 9.49 % and a rear-side PCE of 1.04%.

Hepatic stellate cells (HSCs) are the central link of the occurrence and development of hepatic fibrosis, and autophagy promotes HSCs activation. N6-methyladenosine (m6A) RNA modification can also control autophagy by targeting selected autophagy-associated genes. but up to now, little research has been done on the m6A modification autophagy-related genes (ATGs) in hepatic fibrosis. Here, we identify ATG9A as a previously unrecognized m6A modified ATG using m6A-sequencing (m6A-seq). Importantly, ATG9A is upregulated in liver fibrosis mice and primary biliary cirrhosis (PBC) patient liver tissue. Mechanistically, based on the presence of m6A binding sites on ATG9A, ATG9A promotes HSCs autophagy in an m6A dependent manner, thereby enhancing HSCs activation. Noteworthy, FTO is identified as the upstream of ATG9A, and knockdown of ATG9A can prevent FTO-induced HSCs autophagy and activation. In bile duct ligation (BDL) or CCL4-induced liver fibrosis mouse models, lowering ATG9A alleviated liver fibrosis through PI3K/AKT/mTOR pathway and TGFβ1/smad3 pathway. Taken together, our results provided that ATG9A is a potential prognostic biomarker and therapeutic target for patients with liver fibrosis.

Antimony sulfide-selenide Sb 2 (S,Se) 3 as a promising absorber material has drawn extensive attention owing to its rewarding photoelectric properties, low toxicity, and earth abundant components. Here, an available and highly effective method, in situ hydrothermal growth accompanied with postselenization, is successfully applied to fabricate Sb 2 (S,Se) 3 solar cells. The rationale for the preparation of Sb 2 S 3 precursors by the hydrothermal method is discussed, and detailed characterization of Sb 2 (S,Se) 3 films selenized with different temperatures is also carried out. Finally, a solar cell with structure of FTO/CdS/Sb 2 (S,Se) 3 /Spiro-OMeTAD/Au is fabricated, which delivers an encouraging 6.14% efficiency with V oc of 732 mV, J sc of 14.6 mA cm −2 , and fill factor of 60.8%. This work provides valuable references for further development and improvement of Sb 2 (S,Se) 3 solar cells.

The malachite green (MG) has been widely used in the aquaculture and textile industry as drugs and dyes, respectively. In recent years, it has been found that MG has side effects such as carcinogenicity, teratogenicity and mutagenesis. So it becomes particularly important to degrade MG for these industries. In this paper, a set of equipment using FTO conductive glass was developed for degradation of MG. Several factors affecting the efficiency of electrochemical degradation, including the solution of pH, electrolyte, applied current density and degradation time were investigated. Based on the results of single-factor experiment, the response surface methodology (RSM) was used for optimal conditions. The degradation rate of MG reaches above 98% by electrolysis in 6.56 g/L NaCl (pH 8.84) solution with current density as 8.61 mA/cm 2 for 20 min. The degradation process was preliminarily investigated by ultraviolet-visible(UV-vis) spectroscopy, fluorescence spectrometry, and total organic carbon analysis. The equipment and operation is simple, therefore could be used for the degradation of wastewater yielded during production.

Carbon quantum dot sensitized Pt@Bi2WO6/FTO electrodes (simplified as CQDs-Pt@Bi2WO6/FTO) were successfully prepared by loading platinum particles onto Bi2WO6 nanoplates via a photo-deposition method and sensitized carbon quantum dots (CQDs) via a dip-coating method. The photoelectro-catalytic properties of the Pt@Bi2WO6/FTO and CQDs-Pt@Bi2WO6/FTO electrodes for methanol oxidation were investigated. The results indicated that the CQDs-Pt@Bi2WO6/FTO electrode shows higher photoelectro-catalytic activity and better stability than that of the Pt@Bi2WO6/FTO electrode. The higher photoelectro-catalytic performance for methanol oxidation was attributed due to the special synergetic effects between the photocatalytic and electrocatalytic process under solar light irradiation. More importantly, the introduction of CQDs broaden the photoresponse range of the Bi2WO6 material and improves the mobility of the photocarriers. Meanwhile, the doped CQDs act as preferential adsorption sites for the intermediate carbonaceous species during methanol oxidation. This not only alleviates CO poisoning towards the Pt particles, but also improves the efficiency of methanol oxidation by constructing a new type of CQDs-Pt electrocatalyst. The composite material, which combines the dual function of photocatalysis and electrocatalysis will be a promising candidate for new photoelectro-catalytic fuel cells.

The fabrication of kesterite Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cells based on fluorine-doped tin oxide (FTO) substrates, as an alternative to conventional molybdenum, is highly attractive for applications in semitransparent, bifacial and tandem photovoltaic devices. Although FTO exhibits phase stability during the high-temperature annealing process required for CZTSSe grain growth, its electrical conductivity decreases significantly, impairing carrier transport and limiting device performance. Addressing this issue necessitates lowering the annealing temperature without compromising the crystallinity of the CZTSSe absorber layer. In this study, we demonstrate the growth of high-crystallinity CZTSSe absorbers on FTO substrates at a reduced temperature of 500 °C, facilitated by silver (Ag) and sodium (Na) doping in the precursor film. The absorbers were fabricated from a 2-methoxyethanol-based molecular ink, and the annealing duration was systematically optimized. We found that the crystallinity and morphology of the CZTSSe layer are strongly influenced by annealing time. An optimal film morphology was achieved with a 15-min anneal, whereas shorter annealing (≤10 min) resulted in incomplete crystallization, and extended annealing (>20 min) promoted void formation within the absorber due to Ostwald ripening. Furthermore, the optimized annealing process reduces the interface defect density and broadens the depletion width of the device, leading to a record power conversion efficiency of 9.4 % for CZTSSe solar cells on bare FTO substrates. These results provide important insights for developing efficient bifacial CZTSSe solar cells.

Large-area, high-density, and directionally arranged (Al x Ga 1- x ) 2 O 3 nanorod arrays were successfully synthesized in situ on FTO glass substrates via a simple hydrothermal method using Ga(NO 3 ) 3 and Al(NO 3 ) 3 mixed aqueous solution as precursor. Compared to powder samples, the thin-film samples exhibited a stronger preferred orientation, with the nanorod arrays growing preferentially along the [110] direction. The formation mechanism of the oriented nanorod arrays is proposed according to the model of liquid phase heterogeneous nucleation and anisotropic crystal growth. As the Al composition increased, the crystallite size decreased, the specific surface area increased, and the optical band gap widened. This study presents a promising candidate for further gas sensor application.

CdTe quantum dots (QDs) were synthesized in aqueous solution using thioglycolic acid (TGA) as stabilizing agents. The interaction between TGA-CdTe QDs and fat mass and obesity-associated (FTO) protein was investigated by fluorescence, UV–visible absorption, synchronous fluorescence and three-dimensional fluorescence spectroscopy. Results revealed that TGA-CdTe QDs could strongly quench the intrinsic fluorescence of FTO protein with a static quenching procedure. Both the van der Waals and hydrogen bonding played a major role in stabilizing the complex. The binding constant and thermodynamic parameters at different temperatures were obtained. In addition, we found that the fluorescence intensity of QDs was significantly enhanced by the addition of FTO protein. Based on this, a sensitive method for detecting FTO protein was obtained in the linear range of 5.52 × 10 −9 –6.62 × 10 −7 mol L −1 with the detection limit of 1.14 × 10 −9 mol L −1 . The influences of factors on the interaction between FTO protein and TGA-CdTe QDs were studied.

TiO2is one of the most attractive semiconductors for use as a photoanode for photoelectrochemical (PEC) water oxidation. However, the large-scale application of TiO2photoanodes is restricted due to a short hole diffusion length and low electron mobility, which can be addressed by metal doping and surface decorating. In this paper we report the successful synthesis of hierarchical Ta doped TiO2nanorod arrays, with nanoparticles on the top (Ta:TiO2), on F-doped tin oxide (FTO) glass by a hydrothermal method, and its application as photoanodes for photoelectrochemical water oxidation. It has been found that the incorporation of Ta5+in the TiO2lattice can decrease the diameter of surface TiO2nanoparticles. Ta:TiO2-140, obtained with a moderate Ta concentration, yields a photocurrent of ∼1.36 mA cm−2at 1.23 V vs. a reversible hydrogen electrode (RHE) under FTO side illumination. The large photocurrent is attributed to the large interface area of the surface TiO2nanoparticles and the good electron conductivity due to Ta doping. Besides, the electron trap-free model illustrates that Ta:TiO2affords higher transport speed and lower electron resistance when under FTO side illumination.Keywords:hierarchical TiO2;Ta doping;charge separation;photoelectrochemical water oxidation

Copper antimony sulfur (CuSbS 2 ) possesses a band gap of about 1.5 eV, high absorption coefficient of > 10 4 cm −1 and abundant compositions, which is considered as one of the potential photovoltaic absorbers. In this work, we propose a facile ion-exchange assisted chemical bath deposition (IEACBD) method, which uses Cu + to replace Sb 3+ from the matrix of Sb 2 S 3 and then combine into CuSbS 2 alloy. Through systematic study, we found that this ion-exchange is a simultaneous interdiffusion process of Cu + and Sb 3+ ions, which enables a uniform mixture of those two elements. But it also inevitably produces a Sb 2 O 3 by-product on the surface of the film because of the alkaline environment of this chemical bath. To further remove it, we introduce a mild etching process with BDCA solution for Sb 2 O 3 and then obtain a high-quality CuSbS 2 . Finally, we assemble an inorganic CuSbS 2 solar cell with the architecture of FTO/TiO 2 /CdS/CuSbS 2 /Carbon/Ag, and delivering a photoelectric conversion efficiency of 0.75 %. This enriches the preparation method of CuSbS 2 thin film and also provides guidance for the synthesis of the similar multiple chalcogen compounds.

Aldehyde dehydrogenases superfamily (ALDHs), which are ubiquitously present in various organisms with diverse subcellular localizations, play a crucial role in regulating malignant tumor progression; Nevertheless, their involvement in clear cell renal cell carcinoma (ccRCC) has not been elucidated. In this study, we performed comprehensive bioinformatics analyses on the 19 ALDHs genes, and identified ALDH9A1 as a key contributor in ccRCC. Expression patterns and clinical relevance of ALDH9A1 were determined using bioinformatics analyses, real-time PCR, western blotting, and immunohistochemistry. To explore the underlying mechanism behind the tumor suppressor role of ALDH9A1, RNA sequencing, methylated RNA immunoprecipitation, luciferase reporter assay, mass spectroscopy, immunoprecipitation, mutational studies and immunofluorescence were employed. The impact of ALDH9A1 in ccRCC progression and metabolic programming was assessed through both in vitro and in vivo. Here, this study revealed ALDH9A1 as a tumor suppressor gene in ccRCC. The fat mass and obesity associated protein (FTO) was identified as a demethylase for ALDH9A1 mRNA, resulting in its reduced stability and expression levels in ccRCC. Functional experiments demonstrated that the deficiency of ALDH9A1 in ccRCC promoted tumor proliferation, invasion, migration and lipid accumulation. Mechanistic insights illustrated that the diminished levels of ALDH9A1 resulted in the failure to sequester nucleophosmin 1 (NPM1) within cytoplasm, thereby suppressing the transcription of IQ motif containing the GTPase-activating protein 2 (IQGAP2), subsequently activating the AKT-mTOR signaling, ultimately fostering tumor progression and lipid accumulation. In conclusion, the present study highlights the robust prognostic significance of ALDH9A1 and delivers a comprehensive understanding of ALDH9A1-NPM1-IQGAP2-AKT axis in ccRCC. These findings established a solid research foundation for novel therapeutic strategies for ccRCC patients.

In this work, highly regular TiO 2 array films consisting of nanorods with a diameter of ∼119 nm were grown on FTO via a facile hydrothermal method. Then Pt nanoparticles with a size of ∼5 nm were modified on the surface of TiO 2 nanorods via an in-situ reduction process. The gas-sensing performances of pristine TiO 2 and Pt-modified TiO 2 samples were systematically tested. The introduction of Pt nanoparticles could enhance the response and stability toward CO gas and decrease the optimal operating temperature from 400 °C to 360 °C. And the Pt/TiO 2 -based sensor with a Pt content of 1.5 wt% exhibits the maximum CO sensitivity. Furthermore, the adsorption energies of Pt-modified or Pt-doped TiO 2 for CO molecules were calculated using first-principles calculations. The chemical sensitivity of Pt to CO molecules may be responsible for the improved CO sensitivity. Additionally, the unique nanorod array structure of Pt/TiO 2 and the nano-Schottky junction generated between them are helpful in enhancing the gas-sensing property.
