With exceptionally large RI changes, the evanescent field of cladding mode in ZIF-8 is greatly enhanced to sense the vapor-MOF interactions. As a proof-of-concept, a LPFG sensor with ZIF-8 coating showed a high sensitivity of 1.33 pm ppm-1 in the linear range from 9.8 ppm to 540 ppm for the sensing of ethanol vapor. The investigation of light-matter interactions in ZIF-8 provides a useful guideline for the design and fabrication of MOF-based optical waveguide/fiber sensors.The raw analytical concentration values of semi-volatile organic compounds (SVOCs) in ocean sediments do not necessarily reflect the bioavailable fractions of SVOCs in the sediments due to factors such as the total organic carbon content of sediments (TOC) and the percentage of fine particles in sediments (% fines) as they are believed to affect the extraction efficiency of SVOCs from sediments. Corrective actions are therefore taken to minimize their influence on measurements. In doing so, a broad and uniform correlation is assumed to exist between the 'native' levels of SVOCs and TOC or % fines across ocean strata. However, the validity of this blanket assumption is not yet verified. In this study, we examined the strength of the assumption using DDTs, PAHs and PCBs levels in sediments from Santa Monica Bay (SMB), California, USA. (The distribution patterns of these SVOCs in SMB are known and reproducible for quality assurance.) As our results show, a uniform correlation between SVOC levels and TOC or % fines across strata is mostly absent. For example, PAH and PCB levels show negative correlation with TOC or % fines, and only in canyon sediments, DDT levels correlate positively with both TOC and % fines across at least three strata. Furthermore, the distribution of PAH molecules appears to be controlled by molecular size with smaller PAHs being found almost exclusively in the canyons. Our finding here, being the first of its kind, suggests that more work is needed to clarify the reporting of SVOC levels in ocean sediments.The most significant cost driver for efficient bio-production of edible animal proteins is the cell culture media, where growth factors account for up to 96% of the total cost. The culture media must be serum-free, affordable, contain only food-grade ingredients, be efficient to promote cell growth and available in massive quantities. The commercially available serum substitutes are expensive and not necessarily food-grade. Identifying inexpensive food-safe alternatives to serum is crucial. By-products from food production are available in massive quantities, contain potential factors that can promote growth and are promising ingredients for serum replacement. The main goal of this study was to explore if food-grade by-product materials can be used as growth promoting agents in skeletal muscle cell culture to develop a tailor-made serum free media. Different by-products, including chicken carcass, cod backbone, eggshell membrane, egg white powder and pork plasma were enzymatically or chemically hydrolyzed. Thd. We suggest that these materials have the potential to replace serum during cultivation and as such be included in a tailor-made serum-free media.This paper reports measurements of the temperature dependence of the rate constants for H-atom abstraction reactions from propane and n-butane by the light isotopic H-atom muonium (Mu), kMu(T), over temperatures in the range 300 K to 435 K. Simple Arrhenius fits to these data yield activation energies, E, that are some 2-4 times lower than E found from corresponding fits for the H + propane and H + n-butane reactions studied elsewhere, both experimentally and theoretically, and fit over a similar temperature range. These activation energies E are also much lower than estimated from zero-point-energy corrected vibrationally adiabatic potential barriers, both results suggesting that quantum tunneling plays an important role in determining kMu(T) and for the Mu + propane reaction in particular. The results are expected to pose a considerable challenge to reaction rate theory for isotopic H-atom reactions in alkane systems.Recently, we demonstrated that the in situ formation of a building block is an attractive synthesis strategy for creating novel clusters with controllable structures. Herein, we present the design and synthesis of the first tantaloselenite polyoxoanion [Se4(TaO2)6(OH)4O17]4- (1) and a series of lanthanide derivatives (RE3+ = Tb3+, Dy3+, Ho3+, Er3+, Tm3+, Yb3+). In total, we report seven clusters that vary in both composition and structure but which share the same Se4(TaO2)6 building block. H-Cys(Trt)-OH order The compounds are fully characterized by single-crystal X-ray diffraction, IR spectra, TG, and PXRD and their decolorization properties for RhB have also been investigated. Compound 1 exhibits good photocatalytic activity for the decolorization of RhB while the introduction of lanthanide into the framework can also maintain this activity.A new photocatalytic composite material, based on flexible functional polyacrylonitrile nanofibers (denoted as f-PAN NF), was developed by depositing composite layers of α-TiO2 and cone-shaped titanate (H2Ti5O11·3H2O) successively. The α-TiO2 coated on f-PAN NF as a seed accelerated the nucleation of titanate. Cone-shaped titanate deposited on α-TiO2@f-PAN NF tightly at 35 °C with the assistance of cyanuric acid via Ostwald ripening. Due to the uniform distribution of cone-shaped titanate, the photocatalytic performance of hybrid f-PAN NF was remarkable under LED light irradiation and yielded additional photocatalytic applications as well. In addition, the composite photocatalyst exhibited better reusability and retrievability because of the special design involving a bonding between the nanofibers and layers.We herein report a simple anthraquinone-imidazole-based compound, 2-(furan-2-yl)-1H-anthra[1,2-d]imidazole-6,11-dione (FAI), as an effective colorimetric and fluorometric Ag+ sensor. In 1,4-dioxane/water (3  7, v/v, pH 7.4), FAI could selectively recognize and detect Ag+ ions via significant fluorescence quenching at 606 nm, accompanied by a rapid color change from yellow to orange. FAI exhibited high sensitivity to Ag+ in a linear dynamic range from 0.8-32 μM, with the detection limit of 66 nM. Job's plot analysis and HRMS studies supported the formation of the FAI-Ag+ complex in a ratio of 1  1. The in situ generated FAI-Ag+ complex was further utilized as a reversible sensor to detect biothiols (Cys, Hcy, GSH) through a decomplexation reaction, with the detection limit of 89 nM, 174 nM and 208 nM for Cys, Hcy and GSH, respectively. In addition, FAI with low cytotoxicity was efficient in monitoring Ag+ ions and biothiols in living human hepatoma cells SMMC-7721 as demonstrated by fluorescence microscopy imaging.
