Although FTO films exhibit the coexistence of electrical conductivity and optical transparency, the pursuit of even more superior performance remains the pivotal objective for next-generation photovoltaic architectures. Element doping merely increase the carrier concentration, leading to an increase in impurity ion scattering, which results in a deterioration of mobility and optical transmittance. This paper reports a new method that introducing cationic surfactants to form micellar templates, which alters the sol-gel process of the precursor solution, increases the grain size and promotes the oriented growth of fluorine-doped tin oxide (FTO) film. The FTO films grown by spray pyrolysis with the addition of hexadecyl trimethyl ammonium chloride (CTAC) possesses higher mobility and figure of merit than original FTO film. The FTO film fabricated with the addition of 0.1 g CTAC exhibits the optimum performance, delivering a high carrier mobility of 24.4 cm 2 ·V −1 ·s −1 and a reduced sheet resistance of 9.8 Ω/sq. The calculated figure of merit reaches 3.91 × 10 −2 Ω −1 , representing a 30.7% enhancement compared to the pristine FTO film.

Fluorine-doped tin oxide (FTO) is a cornerstone transparent conducting oxide in electrochemistry and materials science, yet its stability is often assumed rather than verified. This work presents a time-resolved operando investigation into the degradation of the FTO electrode, quantitatively mapping its chemical and electrochemical stability in acidic (0.5 M H 2 SO 4 ), neutral (1.0 M KCl), and alkaline (1.0 M KOH) environments. By employing time-resolved electrochemical impedance analysis and cyclic voltammetry-coupled electrochemical impedance spectroscopy protocol, we simultaneously track changes in FTO resistance and double-layer capacitance to deconvolve distinct degradation mechanisms. Our findings reveal that FTO stability is highly conditional. Alkaline media are universally corrosive, causing severe surface roughening (capacitance increases >90 %) and conductivity loss even during simple chemical immersion. In contrast, under acidic and neutral conditions, cathodic cycling drives surface roughening, whereas anodic cycling leads to surface smoothing. Most notably, the impact on conductivity is potential-specific: anodic polarization improves conductivity in neutral KCl but is destructive in KOH, where stannate (SnO 3 2− ) formation causes the largest rise in resistance (+7.3 %). By correlating electrical parameters with specific redox processes, this study provides a quantitative framework for understanding FTO degradation and establishes critical operating windows to ensure FTO reliability in electrochemical applications.

In this paper, the perovskite solar cells (PSCs) with the structure of FTO glass/compact TiO 2 /mesoporous TiO 2 /CH 3 NH 3 PbI 3 /carbon electrode were designed and fabricated. The CH 3 NH 3 PbI 3 absorption layers were prepared using one-step solvent-engineering method. The effects of volume ratios of dimethyl sulfoxide (DMSO) to N, N-dimethylformamide (DMF) and molar ratios of PbI 2 to CH 3 NH 3 I (MAI) on structure and morphology of CH 3 NH 3 PbI 3 absorption layers, as well as photovoltaic performance of PSCs were studied. The results show that the PSCs based on a specific ratio of PbI 2 :MAI = 1:1.4 and DMSO:DMF = 1:3 exhibited an optimal photovoltaic performance, yielding an open-circuit voltage (V oc ) of 0.72 V, short-circuit current density (J sc ) of 25.98 mA/cm 2 , fill factor (FF) of 0.46, and power conversion efficiency (PCE) of 8.45%. And the incident photon-to-electron conversion efficiency (IPCE) is close to 85% between 400 and 600 nm visible region.

To achieve an economic advantage, nanocrystalline Ba 0.5 Sr 0.5 TiO 3 (BST) thin films were prepared on FTO-coated glass substrates using an aqueous sol–gel process. The crystal structures and chemical states of the obtained thin films were characterized by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The XRD patterns confirmed the perovskite structure of the BST samples, while XPS analysis demonstrated that Ba element was in its single oxidation state in the film with annealing temperature of 600 °C. In contrast, Ba was present in a mixed oxidation state upon increasing the annealing temperature. It was found that the BST thin film prepared at a relatively low annealing temperature of 600 °C exhibited optimal crystallinity and superior dielectric properties , along with excellent optical transparency. More specifically, this film exhibited a dielectric tunability of 44.81% (1.33 MV/cm), a figure of merit of 56.01, and an average transmittance of 87.2% in the visible region.

Most photoelectrocatalytic (PEC) reactions are performed in the liquid phase for convenient electron transfer in an electrolyte solution. Herein, a novel PEC reactor involving a tandem combination of TiO2 nanorod array/fluorine-doped tin oxide (TiO2-NR/FTO) working electrodes and an electrochemical auxiliary cell was constructed to drive the highly efficient PEC oxidation of indoor gas (NOx). With the aid of a low bias voltage (0.3 V), the as-formed PEC reactor exhibited an 80% removal rate for oxidizing NO (500 ppb) under light irradiation, which is much higher than that of the traditional photocatalytic (PC) process. Upon being irradiated by light, the photogenerated electrons are quickly separated from the holes and transferred to the counter electrode (Pt) owing to the applied bias voltage, leaving photogenerated holes in the TiO2-NR/FTO electrode for oxidizing NO molecules. Moreover, both dry and humid NO could be effectively removed by the tandem TiO2-NR/FTO-based gas-phase PEC reactor, indicating that the NO molecules could also be directly oxidized by photogenerated holes in addition to hydroxyl radicals. The presence of trace amounts of water could promote the PEC oxidation of NO owing to the formation of hydroxyl radicals induced by reactions between the water and holes, which could further oxidize NO. This PEC reactor offers an energy-saving, environmentally friendly, and efficient route to treat air polluted with low concentrations of gases (NOx and SOx).

The gut microbiota has been linked to a number of neurological disorders. However, it is unclear whether the gut microbiota is involved in the genesis of chronic itch, a refractory condition that afflicts patients both physically and mentally. Here, we report that depletion of gut microbiota enhances tolerance to itch in mice orally administered with antibiotics (ABX) and mice free of germ. Of note, oral gavage with Bacteroides fragilis (B. fragilis), a prominent species of the genus Bacteroides with most differential change, corrected the ABX-induced itch dysfunction through its driven metabolite acetyl-l-carnitine (ALC). Mechanistically, gut microbiota or B. fragilis depletion caused a decrease in RNA N6-methyladenosine (m6A) demethylase FTO expression in the dorsal horn and a consequent increase in RNA m6A sites in Mas-related G protein-coupled receptor F (MrgprF) mRNA, leading to decreased MRGPRF protein. The downregulation of FTO was triggered by inactivation of ETS proto-oncogene 1 (ETS1), a transcription factor that binds to the Fto promoter. These findings support a gut microbe – spinal connection in modulation of itch sensation in RNA m6A epigenetic-dependent manner and highlight a critical role of ALC in linking the altered B. fragilis and itch dysfunction.

Clenbuterol (CLB) is a notorious “lean meat essence”, which has harmful effects on human health. In this study, the binding of CLB to two proteins, human serum albumin (HSA) and the human fat mass and obesity associated protein (FTO), have been investigated by spectroscopic and molecular modeling methods. Fluorescence data revealed that CLB could bind to HSA (or FTO) to form a complex. Thermodynamic analysis and molecular modeling indicated that the binding process was a spontaneous molecular interaction procedure, in which hydrophobic interaction played a major role. Results indicated that CLB could lead to some microenvironmental changes of both proteins.

Background Osteoarthritis (OA) is currently the most common age-related degenerative joint disease, but there remains a lack of disease-modifying therapy for OA treatment. This study aimed to elucidate the critical roles and underlying mechanism of the fat mass and obesity associated gene (FTO) in OA pathogenesis induced by high fat diet (HFD) and HFD coupled with destabilized medial meniscus (DMM) surgery, and to ascertain the synergistic action of the two in OA pathogenesis. Methods Mouse models were established using solely HFD feeding and combined HFD feeding and DMM surgery. Primary mouse chondrocytes were treated with palmitic acid (PA) and interleukin-1β (IL-1β) to simulate lipotoxicity and inflammation. FTO expression was modulated via genetic, adenoviral, or pharmacological methods. Downstream pyruvate dehydrogenase phosphatases 2 (PDP2) and YTH N 6 -methyladenosine RNA binding protein 2 (YTHDF2) were similarly manipulated by siRNA or overexpression plasmids; adenovirus-mediated knockdown/overexpression of Pdp2 was applied in vivo . Mechanistic studies included RNA sequencing (RNA-Seq) and methylated RNA immunoprecipitation sequencing (MeRIP-Seq). Results The results revealed reduced FTO expression in the cartilage of both obese OA patients and mouse models. Genetically, adenovirus-induced or pharmacologically-induced FTO inhibition exacerbated OA progression in HFD-fed and HFD+DMM mice. Mechanistically, Fto knockdown downregulated the PDP2 level in an m 6 A-dependent manner via YTHDF2. Pdp2 knockdown exacerbated OA progression in HFD-fed and HFD+DMM mice, whereas PDP2 overexpression markedly alleviated cartilage degeneration. Moreover, YTHDF2 overexpression reversed the role of Fto knockdown in lipid deposition and cartilage degeneration. Conclusions Our study identifies that downregulation of FTO exerts a pivotal effect on OA with obesity. FTO drives disease progression by regulating PDP2 activity, and YTHDF2 mediates the m 6 A modification of FTO to PDP2. Targeting the FTO/YTHDF2/PDP2 axis offers promising therapeutic potential for OA treatment.

In this work, CdS thin films were deposited on glass/fluorine-doping tin oxide (FTO) substrates by low-cost chemical bath deposition (CBD), followed by annealing with CdCl 2 -doping (Cl-doping) to fabricate resistive-type photodetectors (PDs) with a vertical structure of glass/FTO/CBD-CdS:Cl/electrode. The effect of annealing with Cl-doping (AwCl) on the various properties of films and the photodetection performance of PDs were systematically characterized by special testing methods. The results revealed that the surface morphology and crystal structure of CBD-CdS:Cl films were improved, accompanied by an enhancement of hexagonal phase (002) crystal plane (wurtzite structure), and the optical bandgap of films can be adjusted between 2.43 and 2.26 eV while the electron activation energy of the films was reduced from 75.9 to 10.3 meV after AwCl. Furthermore, the light responsivity of CBD-CdS:Cl PDs were 0.57, 0.59 and 1.67 A/W under 365, 400 and 530 nm illumination at a bias of −2.0 V, respectively, and the detectivity of photons at corresponding wavelengths were 3.7 × 10 8 , 3.9 × 10 8 and 1.08 × 10 9 Jones. Meanwhile, the PDs showed optimized repeatability and improved sensitivity under periodic illumination. The above results demonstrated that the CBD-CdS:Cl PDs with a vertical structure developed in this work had good detection performance at certain characteristic wavelengths.

In this work, the binding of four hydroxyanthraquinones (HAQs) to fat mass and obesity-associated (FTO) protein has been studied using fluorescence, UV-vis absorption and circular dichroism spectroscopy as well as molecular docking analysis. Analysis of fluorescence data showed that the binding of HAQs to FTO occurred via a static quenching mechanism. Thermodynamic analysis and molecular docking results suggested that hydrophobic force played a major role in stabilising the HAQ-FTO complex. Circular dichroism spectra indicated that the secondary structure of FTO was changed by the addition of HAQs. Results also showed that emodin had the strongest quenching and binding ability among four HAQs.

Single-phase photoanodes often suffer inferior charge transport, which can be mitigated by constructing efficient heterojunctions. Thus, we have fabricated a fluorine-doped tin oxide (FTO)/WO3/BiVO4heterojunction using hydrothermal and spin-coating methods. Surface engineering was exploited to further accelerate the reaction kinetics, which was achieved via post-modification with NaOH solution. This treatment alters the surface chemical state of the BiVO4nanoparticles, leading to enhanced charge transport and surface water oxidation processes. As a result, the optimized sample can produce a photocurrent more than two times that of WO3. The simple post-treatment provides a viable and cost-effective strategy for promoting the photoelectric properties of photoanodes.Keywords:FTO/WO3/BiVO4heterojunction;photoelectrochemical;post-modification;surface engineering;solar water-splitting
