    In addition, the presence of Ni and La species greatly enhanced the antibacterial performance of the NiLa-LDOs/Fe3O4 toward E. coli. Results obtained from this study indicate porous NiLa-LDOs/Fe3O4 can be a promising multifunctional material for the treatment of secondary effluent. Suspended biofilm carriers mediating direct interspecies electron transfer (DIET)-based syntrophic metabolism is a promising strategy to enhance anaerobic digestion and methane production by associating the advantages of conductive suspended biofilm carriers and anaerobic integrated floating fixed-film and activated sludge (An-IFFAS) process. However, the current knowledge of DIET using conductive suspended biofilm carrier is still limited. In this study, novel electron mediator suspended biofilm carriers had been prepared by introducing a series of graphite powders (3 wt%, 5 wt% and 7 wt%) into high-density polyethylene (HDPE), and applied in An-IFFAS reactors. Results showed that An-IFFAS reactors filled with graphite-modified carriers could enhance the degradation of organic matters and the production of methane significantly in comparison with the control reactor filled with conventional HDPE carriers at organic loading rates (OLRs) of 5.9-23.7 kg COD/m3/d. Microbial analysis proved that 7 wt% graphite-modified carrier improved approximately 4.2% abundance of Geobacter and 7.3% abundance of electrotrophic methanogens (Methanothrix) that exchange electron via DIET comparing with that of HDPE carriers, respectively. These findings demonstrated that electron mediator suspended biofilm carrier was able to potentially proceed DIET and enhance the efficiency of anaerobic digestion and recover CH4-related energy. Program evaluation is an important aspect of any organization. The ability to reflect on past performance and plan for the future is essential to an organization’s health and future growth. This exploratory study is part of a larger program evaluation initiative that examined the efficacy of a regionally based organization that provided funding to community groups to alleviate poverty. The purpose of the study was to explore testimonials provided by participants of the organization’s funded programs, to determine if the participants were satisfied with the programs and the extent to which participants’ perceptions are congruent with the goals of the organization. Content analysis was used to examine 3494 testimonials from 77 different agencies. Three overall themes were determined from the analysis 1 Developing Social Networks, 2 Learning Comes in Various Forms, and 3 Developing Self-Efficacy. Findings from the testimonials suggest that the benefits of the programs are highly social and that connections with others are important, but also provide rich opportunities for learning new skills and knowledge, as well as gaining confidence and a sense of control. The findings from this analysis support one goal of the organization which is to engage people living in poverty in meaningful ways. A core-shell molecular imprinting fluorescence nanosensor was developed for the ratiometric fluorescence and visual detection of folic acid (FA). The nanosensor was prepared by anchoring imprinting shell on the silica nanoparticles, and embedding the CdTe quantum dots in imprinted shell to provide FA-dependent fluorescence signals. Under the optimum conditions, a favorable linearity relationship between the fluorescence intensities ratio (I449/I619) and the FA concentration over 0.23-113 μM was offered with a detection limit (LOD) of 48 nM. The visual detection for FA was realized by evaluating profuse fluorescence color change from red to pink to purple to final blue. The proposed sensor possessed excellent sensing performances of rapid response, high precision, super sensitivity and selective recognition. Furthermore, endogenous FA was detected in real samples ranging from 37.4 to 265.8 μg/100 g; satisfactory spiked recoveries were obtained within 94.8-104.2%, which conformed to the measurement results by HPLC-UV. The mechanisms of the unfolding and aggregation of PSE-like chicken meat protein at extreme alkaline pHs (pH 11.0, 11.5 and 12.0) were studied and related to the physical properties of edible films. Results of asymmetrical flow field-flow fractionation coupled with various detectors showed that pH 12.0 leads to a certain degree of protein aggregation, which could also be observed in atomic force microscopy (AFM) images. Higher levels of protein denaturation and unfolding, as proved by the circular dichroism spectrum, could result in aggregates formation, whereas all pH-adjusted groups exhibited similar flow behavior. The pH 11.0 sample exhibited films with higher water resistance compared to others. Comparatively, solubilizing PSE-like meat protein at pH 11.5 could result in better edible films with greater mechanical properties, water resistance and transparency. Our results elucidated the effects of the PSE-like chicken meat protein unfolding and aggregation on edible film properties under various extreme alkaline pH conditions. A physicochemically stable emulsion was developed by using a novel emulsifier, which was self-assembled colloidal complex of gelatin (GLT) and proanthocyanidins from Chinese bayberry (Myrica rubra Sieb et Zucc.) leaves (BLPs), with epigallocatechin-3-O-gallate (EGCG) as structure units. The GLT-BLP colloidal complexes were spherically shaped by transmission electron microscope (TEM). The data of Fourier transform infrared spectrum (FTIR), circular dichroism (CD), isothermal titration calorimetry (ITC) revealed that the main binding force between GLT and BLPs of the colloidal complexes was hydrogen bond. The incorporation of BLPs to GLT provided GLT with stronger affinity at oil-water interface and thus enhanced the physical stability of GLT-stabilizing emulsion. In addition, the emulsions stabilized by the colloidal complexes showed higher oxidation stability than that stabilized by free GLT only. The novel emulsifier developed in this study have potential applications as functional emulsifiers in food-grade emulsions with high anti-oxidation activity. find more
