摘要:
The first example of Nd@C3 N4 -photoredox/chlorine dual catalyzed alkylation with unactivated alkanes as the alkyl sources has been developed, which allows for the synthesis of various 4-alkylated cyclic sulfonyl ketimines. In this process, chlorine functions as both a redox and hydrogen atom transfer catalyst. The synergism of the reversible Nd2 + /Nd3 + and Cl<overline>/Cl (center dot) redox pairs significantly enhances overall photocatalytic efficiency. The in vitro anticancer activity of 4-alkylated products was evaluated by using the CCK8 assay against both human choroidal melanoma (MUM-2B) and lung cancer (A549) cell. Compound 3da showed approximately triple the potency of 5-fluorouracil.

摘要:
In this paper, a switched linear parameter-varying (LPV) resilient tracking controller is designed for rigid-body under actuator faults, uncertainties in measurement of scheduling parameters and time-delay in detection of system modes. The nonlinear attitude dynamics of rigid-body is constructed as a switched LPV system in which persistent dwell-time switching rule is used to regulate the switches caused by abrupt and intermittent actuator failures. Thereafter, by constructing a class of both parameter-dependent and time-dependent multiple Lyapunov functions (MLFs), a switched LPV resilient tracking controller is developed in order that the global uniform exponential stability and desired L infinity performance of the underlying system are achieved even with uncertain scheduling parameters, mismatched modes and persistent external disturbances. Furthermore, the nonconvex conditions of control synthesis are converted into parameterized linear matrix inequalities that can be readily resolved via gridding technique. Finally, the availability of the provided approach is evaluated with a numerical simulation.

摘要:
Acoustic phonons have long been believed to dominate the lattice thermal conductivity (kappa l) and the contribution of optical phonons can be neglected in crystal structures. KCaBi, as a high-throughput screening semiconductor with ultralow kappa l [J. Am. Chem. Soc. 144, 4448 (2022)], has been demonstrated that the contribution of optical phonons plays an important role in thermal transport. In this work, by solving the Boltzmann transport equation, it is found that the kappa l of KCaBi is 2.2 at 300K, with acoustic phonons dominating the z-direction kappa l and optical phonons contributing around 50% to the x-direction kappa l under the four-phonon picture. The uncommon contribution of optical phonons also manifests the possibility of tuning the kappa l anisotropy based on optical phonons. Following this line of thinking, it is found that applying tensile strain can cause a more pronounced decrease of acoustic phonon contribution than that of optical counterpart due to the highly dispersive optical branches, thus enhancing the anisotropic ratio of kappa l. Moreover, the microscopic mechanism is elucidated by analyzing the phonon dispersion relation, phonon mode-wise contribution and phonon scattering rates. Our study could provide appealing alternatives for the regulation of phonon transport from the viewpoint of optical phonons.

摘要:
Photocatalysis holds promise for extracting uranium from aqueous solution. Nevertheless, conventional approaches generally rely on sacrificial agents and anaerobic conditions to maintain photocatalytic efficiency, which increases costs and causes secondary pollution. Herein, we introduce the design and synthesis of an S-scheme ZnIn2S4/g-C3N4 (ZISCN) heterojunction photocatalyst for the efficient removal of uranium via in-situ generating ZnIn2S4 on g-C3N4. Photoelectric characterization and theoretical calculation indicate that ZISCN boosts the absorption of visible light and promotes the effective separation and migration of charge carriers by forming an internal electric field (IEF) at the S-scheme heterojunction interface. This configuration integrates the strong reducing electrons of g-C3N4 and the potent oxidation holes of ZnIn2S4. Consequently, the as-synthesized ZISCN can efficiently remove uranium under an air atmosphere without the need for sacrificial agents and anaerobic conditions. The achieved U(VI) removal rate of 94.8 % surpasses that of ZnIn2S4 and g-C3N4 individually. Moreover, the photocatalytic extraction of U(VI) by ZISCN photocatalyst demonstrated excellent stability and anti-interference performance. After five cycles, the U(VI) removal rate remained above 85 %. Mechanism studies reveal that when electrons are generated by light in the ZISCN systems, they can reduce O2, leading to the formation of reactive species ·O2/H2O2. These species subsequently interact with U(VI), resulting in the precipitation of (UO2)O2·2H2O on the surface of ZISCN. This research provides valuable insights for the design of heterojunction photocatalysts for efficient, sacrificial agent-free uranium removal in ambient air environments.

摘要:
Pyridyl-based ketones and 1,6-diketones are both attractive and invaluable scaffolds which play pivotal roles in the construction and structural modification of a plethora of synthetically paramount natural products, pharmaceuticals, organic materials and fine chemicals. In this context, we herein demonstrate an unprecedented, robust and generally applicable synthetically strategy to deliver these two crucial ketone frameworks via visible-light-induced ring-opening coupling reactions of cycloalcohols with vinylazaarenes and enones, respectively. A plausible mechanism involves the selective beta-C-C bond cleavage of cycloalcohols enabled by proton-coupled electron transfer and ensuing Giese-type addition followed by single electron reduction and protonation. The synthetic methodology exhibits broad substrate scope, excellent functional group compatibility as well as operational simplicity and environmental friendliness.

Cadmium (II);FR;PAN;Fluorescence quenching
摘要:
The objective of this study was to establish a novel method of fluorescence for the determination of cadmium using fluorescein (FR) and 1-(2-Pyridinylazo)-2-Naohthalenol (PAN). In the pH 9.75 buffer solution of the ammonia-ammonium chloride, the energy transfer between FR and the PAN can occur, which can result in the quenching of the fluorescence. The addition of Cd (II) to this system enhances the degree of quenching. This phenomenon has led to the establishment of a novel method for the determination of cadmium, which has been optimized in terms of the required experimental conditions. In the optimal experimental conditions, the fluorescence intensity of the system decreased linearly in the range of 7.81 x 10-7 to 2.14 x 10-5 mol L-1. The linear regression equation used in this study was F = 123.63 + 170.65c (x 10-6 mol L-1) under the correlation coefficient of 0.9951, the detection limit of 2.34 x 10-7 mol L-1, and the relative standard deviation of 0.18%. The proposed method was simple, sensitive, fast, and economical. The method can be employed for the determination of cadmium in real samples (tap-water, pond water and Xiangjiang River) with the results demonstrating consistency with the graphite furnace atomic absorption method (t-test). This approach offers an innovative method for the quantification of Cd (II).

摘要:
In this study, nitrogen-doped nanotube-encapsulated iron nanoparticle catalysts (Fe/Fe3C@NCNTs) were prepared using a one-step pyrolysis strategy for the efficiently activating of peroxymonosulfate (PMS) to degrade tetracycline hydrochloride (TC). The embedded structure greatly minimized the leaching of metals and enhanced the catalyst stability. The prepared Fe/Fe3C@NCNT-800 (0.05 g/L) exhibited excellent PMS (0.5 g/L) catalytic activity for the rapid degradation of TC (30 mg/L) with degradation rate of 90.5 % within 5 min under the pH of 7 and 25 degrees C. Its performance was nearly unaffected by environmental factors (temperature, pH, inorganic anions and organic matter). Moreover, the Fe/Fe3C@NCNT-800/PMS system maintained a TC removal rate of 85.5 % after four cycles of degradation experiments, with a negligible amount of metal leaching. X-ray photoelectron spectroscopy, electron paramagnetic resonance spectroscopy and electrochemical measurements showed that iron nanoparticles and graphitic nitrogen promoted Fe2+/Fe3+ cycling and reactive oxygen species generation as catalytic centers. Among them, 1O2 and electron transfer were shown to be the main degradation pathways for degrading TC.
摘要:
BACKGROUND: Lipoapoptosis in Proximal tubular epithelial cells (PTCs) are substantial in the etiology of diabetic kidney disease (DKD), yet the underlying mechanisms warrant further investigation. Acyl-CoA synthetase long-chain family member 5 (ACSL5) facilitates the formation of acyl-CoA, however, the precise role of ACSL5 in lipoapoptosis of PTCs in DKD remains inconclusive. METHODS: Transcriptomic data analysis identified the hub gene Acsl5 associated with lipid metabolism in DKD. The expression of ACSL5 was examined in high-fat diet/streptozotocin (HFD/STZ)-induced diabetic mice and high glucose/palmitic acid (HGPA)-induced mouse proximal tubular epithelial cell (BUMPT). Oil Red O staining, free fatty acids (FFA) ELISA assay, Western Blot, and morphological changes were employed to assess lipid deposition and lipoapoptosis. Furthermore, knockdown and overexpression of ACSL5 were conducted in BUMPT cells, followed by morphological assessment, Oil Red O staining, FFA ELISA assay and Western Blot analysis. Using the ChEA3 database, we predicted that STAT3 may transcriptionally regulate ACSL5. Subsequently, we knocked down STAT3 and evaluated Acsl5 expression via RT-qPCR. Additionally, we investigated whether STAT3 modulates the impact of ACSL5 on lipoapoptosis through Western Blot analysis. RESULTS: We demonstrated, for the first time, a notable upregulation of ACSL5 expression in PTCs in HFD/STZ-induced diabetic mice, accompanied by increased the expression of FATP2, lipid accumulation and heightened lipoapoptosis. In HGPA-treated BUMPT cells, ACSL5 knockdown reduced the expression of FATP2, lipid deposition and lipoapoptosis, whereas its overexpression elevated the expression of FATP2 and exacerbated these effects. These findings strongly suggest that ACSL5 may exacerbate lipoapoptosis in PTCs within a diabetic milieu. From a molecular mechanism perspective, ACSL5 expression decreased after Stat3 knockdown. Concurrent knockdown of Stat3 and overexpression of Acsl5 led to a mitigation of lipoapoptosis compared to sole Acsl5 overexpression. Furthermore, STAT3 promotes the activation of ACSL5 promoter under HGPA conditions. CONCLUSIONS: In summary, our research identified ACSL5 as an important contributor exacerbating lipoapoptosis in the renal proximal tubules within diabetic environments. In addition, we found that ACSL5 is transcriptionally regulated by STAT3.
摘要:
Semi-heterogeneous photocatalysis has emerged as a powerful and productive platform in organic chemistry, which provides mild and eco-friendly conditions for a diverse range of bond-forming reactions. The synergy of homogeneous catalysts and heterogeneous catalysts inherits their main advantages, such as higher activities, easy separation and superior recyclability. In this review, we summarize the recent advances in recyclable semi-heterogenous protocols for the light promoted bond-forming reactions and identify directions for future research according to the different photocatalysts/metal/redox catalysts involved. Notably, this review is not a comprehensive description of reported literature but aim to highlight and illustrate key concepts, strategies, reaction model, reaction conditions and mechanisms.

摘要:
Herein, we develop a self-driven photoelectrochemical system (SDPS) featuring a TiO2 nanorod array (TNR)/Si photovoltaic cell (Si PVC) photoanode and a porous copper foam (CF) cathode for efficient uranium recovery. Under simulated sunlight illumination, this SDPS simultaneously achieves similar to 99.4 % UO22+ recovery and similar to 99.2 % sulfamethoxazole (SMX) removal, with observed rate constant (kobs) value of 0.121 min(-1) and 0.029 min(-1) , respectively, and a maximum power density (P-max) of 0.89 mW center dot cm(-2) when treating complex wastewater of SMX (10 mg center dot L-1)-UO22+ (10 mg center dot L-1). The TNR photoanode absorbs short-wavelength light (lambda < 412 nm), generating electron-hole pairs, while the rear Si PVC absorbs transmission light, creating a self-bias potential that drives electrons transfer towards CF cathode, continuously generating electrical energy in the external circuit. The retained holes and derived center dot OH oxidize SMX, breaking UO22+-SMX complexation, while electrons on the CF reduce UO22+ to insoluble tetravalent uranium (U(IV)) species. This SDPS demonstrates robust performance across varying UO22+ (5 similar to 40 mg center dot L-1) and SMX (0 similar to 40 mg center dot L-1) concentrations, pH ranges (4 similar to 8), coexisting ions, and different types of uranium-containing wastewaters, maintaining stability over 20 cycles. It achieves similar to 97.5 % UO22+ extraction and similar to 99.8 % SMX removal in simulated seawater, with a P-max of 1.27 mW center dot cm(-2) . This work presents a promising resource strategy for uranium extraction.
摘要:
In-situ leaching (ISL) causes non-negligible groundwater pollution. It is urgent to remediate the groundwater after ISL activities. In this study, we evaluated the effectiveness of flow electrode capacitive deionization (FCDI) to treat a simulated groundwater, the uranium (U) and SO42- concentration of which are comparable to groundwater in acid in-situ leaching (AISL) uranium mine for the first time. Moreover, the removal mechanism of U and SO42- were investigated in-depth. It is found that the operational mode, applied voltage and initial SO4 2concentration significantly affect the removal of U and SO42- by FCDI. The removal efficiency of U and SO42- were above 98 % at 75 min under optimal condition, although U in groundwater mainly existed in the form of uncharged UO2(SO4), followed by UO22+ and UO2(SO4)22- . UO22+ and UO2(SO4)2 2- in groundwater migrated into the two poles and were quickly absorbed by flow electrode, which promoted the dissociation of UO2(SO4) or complexation of UO2(SO4) with SO42- . In addition, the anion exchange membrane can absorb UO2(SO4) through complexation. These resulted in the efficient removal of U(VI). FCDI can reduce the U and SO42- concentration of the contaminated water (CU = 10 mg L- 1, CSO42- = 5 g L- 1) to a value lower than the Chinese emission limit (U: 300 mu g L- 1; SO42- : 250 mg L- 1) even after 18 cycles with each cycle operated for 120 min, which informed that FCDI system using activated carbon is of great potential for acidic contaminated water treatment.

摘要:
With the continuous development of nuclear energy, it becomes increasingly important to recover uranium from the radioactive wastewater, in which various organics may combine with uranyl ions (UO22+) to form refractory complexes. Developing highly active cathode materials for uranium reduction is essential to improve the performance of self-driven solar coupling system (SSCS) in treating complex radioactive wastewater. In this study, an activated carbon felt (ACF) cathode is prepared by anodizing carbon felt (CF) in NaOH solution to adjust the surface morphology and functional groups. The ACF is then used in a SSCS combined with a TiO2 nanorods array (TNA) photoanode for the efficient recovery of uranium and the rapid degradation of organic pollutants with simultaneous electricity generation. Compared to CF, the functionalized ACF with oxygen-containing functional groups, provides sufficient sites for UO22+ adsorption and facilitates the charge separation. The SSCS with the ACF cathode exhibits removal ratios of approximately 99.9 % for tetracycline hydrochloride (TCH) and UO22+, with removal rates of ∼ 0.025 and ∼ 0.154 min−1, respectively. In contrast, the SSCS with the CF cathode achieves removal rates of ∼ 0.006 and ∼ 0.026 min−1. Additionally, a maximum power density of 0.94 mW·cm−2 with a fill factor of 23.36 % is achieved. After 20 cycles, the system maintains removal ratios of 99.1 % for TCH and 98.2 % and UO22+. Intensive investigation also reveals that the system functions robustly in treating complex wastewater with a complicated condition of pH, co-exited ions, and various pollutant concentrations. Furthermore, efficient removal of organics and uranium is also achieved from polluted seawater or under real sunlight illumination. This paper presents a simple method to prepare low-cost, highly active and stable cathodes for uranium reduction in an easy-to-operated, energy-saving and economical solar-driven system.
摘要:
Contemporary makeup approaches primarily hinge on unpaired learning paradigms, yet they grapple with the challenges of inaccurate supervision (e.g., face misalignment) and sophisticated facial prompts (including face parsing, and landmark detection). These challenges prohibit low-cost deployment of facial makeup models, especially on mobile devices. To solve above problems, we propose a brand-new learning paradigm, termed "Data Amplify Learning (DAL)," alongside a compact makeup model named "TinyBeauty." The core idea of DAL lies in employing a Diffusion-based Data Amplifier (DDA) to "amplify" limited images for the model training, thereby enabling accurate pixel-to-pixel supervision with merely a handful of annotations. Two pivotal innovations in DDA facilitate the above training approach: (1) A Residual Diffusion Model (RDM) is designed to generate high-fidelity detail and circumvent the detail vanishing problem in the vanilla diffusion models; (2) A Fine-Grained Makeup Module (FGMM) is proposed to achieve precise makeup control and combination while retaining face identity. Coupled with DAL, TinyBeauty necessitates merely 80K parameters to achieve a state-of-the-art performance without intricate face prompts. Meanwhile, TinyBeauty achieves a remarkable inference speed of up to 460 fps on the iPhone 13. Extensive experiments show that DAL can produce highly competitive makeup models using only 5 image pairs. Please visit https://github.com/TinyBeauty for code and demos.
