In this study,a series of CuCl_(2)-modified MnO_(x)-CeO_(x)nanorods were synthesized for the oxidation of Hg^(0).The addition of CuCl_(2)resulted in an enhancement in the catalyst’s Hg^(0)oxidation ability,and Hg^(0)oxidation efficiency reached>97%from 150 to 250°*** the MnO_(x)-CeO_(x)catalysts,Mn^(4+)played the role of the active species for Hg^(0)oxidization,but in the CuCl_(2)-doped catalysts Cl−also contributed to Hg^(0)oxidation,conferring the superior performance of these *** introduction of SO_(2) led to a decrease in the availability of Mn^(4+),and the Hg^(0)oxidation efficiency of MnO_(x)-CeO_(x)decreased from about 100%to about 78%.By contrast,CuCl_(2)-promoted samples maintained a Hg^(0)oxidation efficiency of about 100%during the SO_(2) deactivation cycle due to the high reactivity of Cl−.

In order to ensure food safety， controlling foodborne pathogen contamination is of utmost importance. Growing apprehensions regarding the safety of synthetic antimicrobials， due to their adverse health effects， have prompted a search for alternative options. Plant natural products (PNPs) with antimicrobial activity are being explored as a viable alternative. Among the various antimicrobial natural products studied， plant essential oils， plant flavonoids， plant polyphenols， plant polysaccharides， and plant antimicrobial peptides have been identified as potential candidates. PNPs demonstrate a diverse array of antimicrobial mechanisms， encompassing cell wall and membrane damage， interference with genetic replication， disruption of energy metabolism， and induction of oxidative stress at the single-cell level， as well as inhibition of biofilm formation and quorum sensing at the population level. Certain PNPs have been harnessed as natural antimicrobial agents for the food preservation. The utilization of encapsulation technology proves to be an effective strategy in protecting PNPs， thereby ensuring good antimicrobial efficacy， enhanced dispersibility， and controlled release within food products. The utilization of nanoemulsions， nanoliposomes， edible packaging， electrospun nanofibers， and microcapsules formed by encapsulation has enriched the ways in which PNPs can be applied in food preservation. Although PNPs have great potential in food preservation， their widespread application in the food industry is currently constrained by factors such as production costs， safety concerns， and legal considerations. Chemical synthesis and biosynthesis pathways offer viable strategies for reducing the cost of producing PNPs， and ongoing efforts to assess safety and improve regulatory frameworks are likely to facilitate the broader adoption of PNPs in food preservation practices. This article provides an overview of the main types of PNPs with antimicrobial activity and their prope

This study demonstrated the impacts of the synthesis methods on the textural structures,chemical properties,and Hg^(0)capture capability of the MnO_(x)*** with the samples synthesized using the precipitation(PR)and hydrothermal(HT)methods,the adsorbent prepared via the sol-gel(SG)technique gave the best *** 150℃,ca.90%Hg^(0)removal efficiency was reached after 7.5 h for MnO_(x)prepared by the SG method,ca.40%higher than that of the other two *** specific surface area of the adsorbent synthesized via the SG technique(23 m^(2)/g)was almost double that of the adsorbent prepared by the HT method(12 m^(2)/g)and three times that of the one prepared by the PR method(7 m^(2)/g).The presence of plentiful acid sites from the SG method facilitated the physisorption of Hg^(0),making more Hg^(0)available to be oxidized to HgO by the redox sites and thus giving the adsorbent prepared by the SG method the highest Hg^(0)removal *** strong oxidative ability accelerated the oxidation of the physically adsorbed Hg^(0)to HgO,which explained the higher Hg^(0)removal efficiency of the sample prepared using the HT method than that of the one synthesized by the PR *** the whole Hg^(0)removal cycles,chemisorption dominated,with the initial adsorption stage and the external mass-transfer process playing important roles.

The research aims at investigating the effects of different modalities and combinations of them on English Listening Teaching, exploring the factors influencing the pattern of multimodality with optimal function and setting practical example to improve the quality of English Listening Teaching. The result shows that reasonable utilization of the combination of multimodalities can improve learners’ listening competence;the choice of the combination of multimodalities depends on the context of situation;visual information can give play to positive function providing that it is complementary to auditory information;In addition, L2 subtitling is more beneficial than L1 because it causes less lexical interference.
