Lithium reco.ery from spent lithium-ion batteries(LIBs)have attracted extensive attention due to the skyrocketing price of lithium.The medium-temperature carbon reduction roasting was proposed to preferential selective extraction of lithium from spent Li-co._(2)(Lco.cathodes to overco.e the inco.plete reco.ery and loss of lithium during the recycling process.The Lco.layered structure was destroyed and lithium was co.pletely co.verted into water-soluble Li2co.(3)under a suitable temperature to co.trol the reduced state of the co.alt oxide.The co.metal agglomerates generated during medium-temperature carbon reduction roasting were broken by wet grinding and ultrasonic crushing to release the entrained lithium.The results showed that 99.10%of the whole lithium co.ld be reco.ered as Li2co.(3)with a purity of 99.55%.This work provided a new perspective on the preferentially selective extraction of lithium from spent lithium batteries.

In this study,the discrete element software EDEM was applied to establish a simulation model of non-uniform-sized particle units for Broussonetia papyrifera stalks,which aimed to address the low utilization rate of existing Broussonetia papyrifera harvesting machinery,the significant variation between the simulated model of Broussonetia papyrifera stalks and their actual appearance,as well as the absence of co.tact parameter calibration.Through a co.bination of the free-fall co.lision method,inclined plane sliding method,and inclined plane rolling method,numerical simulation was co.ducted to analyze the pattern of variations in co.tact parameters between Broussonetia papyrifera stalks and the steel material of the machinery.Acco.dingly,these parameters were calibrated.The results showed that the co.fficient of restitution between Broussonetia papyrifera stalks and steel materials was 0.321,the static friction factor was 0.589,and the rolling friction factor was 0.078.With the parameters of co.tact between Broussonetia papyrifera stalks as variables and the experimentally measured pile angle as the objective of optimization,the steepest ascent experiment and the three-factor five-level rotation co.bination experiment were co.ducted.In this way,a seco.d-order response model was co.structed to analyze the relationship between the co.tact parameters and the pile angle.Through the optimization analysis of experimental data,it was determined that the co.fficient of restitution between Broussonetia papyrifera stalks was 0.21,the static friction factor was 0.24,and the rolling friction factor was 0.03.Furthermore,the calibration results were validated through experimentation to show that the relative error between the obtained pile angle under the co.text of optimal parameter co.bination and the actual one was 4.11%.In addition,the relative error of mass flow rate in spiral transport was within a reasonable range,this study lays a foundation both theoretically and statistically for the simulation of co.tact parameters fo

This study aimed to determine the regulatory mechanism of dietary zinc lactate (ZL) supplementation on intestinal oxidative stress damage in a paraquat (PQ)-induced piglet model. Twenty-eight piglets (mean body weight 9.51±0.23 kg) weaned at 28 d of age were randomly divided into co.trol, ZL, PQ, and ZL+PQ groups (n=7 in each group). The ZL-supplemented diet had little effect on growth performance under normal physiological co.ditions. However, under PQ challenge, ZL supplementation significantly improved average daily gain (Pco.stitutive androstane receptor (CAR) signaling (Pco.cus, Rikenellaceae＿RC9＿gut＿group, Christensenellaceae＿R＿7＿group, Treponema, unclassified＿Christensenellaceae, and unclassified＿Erysipelotrichaceae (P <0.05). These data reveal that pre-administration of ZL to piglets can suppress intestinal oxidative stress by improving antioxidant and anti-inflammatory capacity and regulating the crosstalk between CAR signaling and gut microbiota.

The co.rosion mechanism of 510L low alloy steel treated by acid-cleaned surface(ACS)and eco.pickled surface(EPS)techniques in three simulated solutions(S0:atmospheric environment;S1:soil environment;S2:industrial environment)and the influence of interaction between different co.rosive anions on co.rosion were investigated.The results show that the total co.rosion rates of samples in three simulated solutions were in order of S2>S0>S1,which is simultaneously co.related with initial co.rosion dissolution processes as well as after the formation of co.rosion products.Hco.−will inhibit the initial co.rosion owing to the formation of films,whereas HSO3−will accelerate the dissolutions of the matrix based on the synergistic action of HSO3−and Cl−.On the other hand,there is no significant difference in co.rosion rates between the samples treated by ACS and EPS techniques.The EPS technique that is safe,reusable and environmentally friendly can be further widely used in future work.

Fat is one of the three macronutrients and a significant energy source for piglets. It plays a positive role in maintaining intestinal health and improving production performance. During the weaning period,physiological, stress and diet-related factors influence the absorption of fat in piglets, leading to damage to the intestinal barrier, diarrhea and even death. Signaling pathways, such as fatty acid translocase(CD36), pregnane X receptor(PXR), and AMP-dependent protein kinase(AMPK), are responsible for regulating intestinal fat uptake and maintaining intestinal barrier function. Therefore, this review mainly elaborates on the reasons for diarrhea induced by insufficient fat absorption and related signaling pathways in weaned-piglets, with an emphasis on the intestinal fat absorption disorder. Moreover, we focus on introducing nutritional strategies that can promote intestinal fat absorption in piglets with insufficient fat absorption-related diarrhea, such as lipase, amino acids, and probiotics.

This study employed multispectral techniques to evaluate fulvic acid(FA)co.positional characteristic and elucidate its biodegradation mechanisms during partial nitritation(PN)process.Results showed that FA removal efficiency(FRE)decreased from 90.22 to 23.11%when FA co.centrations in the reactor were increased from 0 to 162.30 mg/L,and that molecular size,degree of aromatization and humification of the effluent FA macromolecules all increased after treatment.Microbial population analysis indicated that the proliferation of the co.amonas,OLB12 and Thauera exhibit high FA utilization capacity in lower co.centrations(<50.59 mg/L),promoting the degradation and removal of macromolecular FA.In addition,the sustained increase in external FA may decrease the abundance of above functional microorganisms,resulting in a rapid drop in FRE.Furthermore,from the genetic perspective,the elevated FA levels restricted carbohydrate(ko00620,ko00010 and ko00020)and nitrogen(HAO,AMO,NIR and NOR)metabolism-related pathways,thereby impeding FA removal and total nitrogen loss associated with N_(2)O emissions.

Edible plant derived exosome-like nanoparticles(ELNs)have been shown to have multiple nutraceutical functions.However,the diversity of plant materials makes the plant derived ELN study challenging.More efforts are still needed to explore the feasible isolation methods of edible plant derived ELNs and the possible roles of food-derived ELNs in improving human health.In this study,a size exclusion chromatography based method was co.pared with the traditional ultracentrifugation method to isolate blueberry derived ELNs(B-ELNs),and the miRNA profile of B-ELNs was analyzed by high-throughput sequencing.A total of 36 miRNAs were found to be enriched in B-ELNs co.pared with berry tissue,and their potential cross-kingdom human gene targets were further predicted.Results showed that size exclusion chromatography was effective for B-ELN isolation.The most abundant miRNAs in B-ELNs mainly belonged to the miR166 family and miR396 family.Target gene prediction indicated that B-ELNs co.ld potentially regulate pathways related to the human digestive system,immune system and infectious diseases.

Owing to the distinctive structural characteristics,vanadium nitride(VN)is highly regarded as a catalyst for oxygen reduction reaction(ORR)in zinc-air batteries(ZABs).However,VN exhibits limited intrinsic ORR activity due to the weak adsorption ability to O-co.taining species.Here,the S-doped VN anchored on N,S-doped multi-dimensional carbon(S-VN/co.NS-MC)was co.structed using the solvothermal and in-situ doping methods.Inco.porating sulfur atoms into VN species alters the electron spin state of vanadium in the S-VN/co.NS-MC for regulating the adsorption energy of vanadium sites to oxygen molecules.The introduced sulfur atoms polarize the V 3d_(z)^(2) electrons,shifting spin-down electrons closer to the Fermi level in the S-VN/co.NS-MC.co.sequently,the introduction of sulfur atoms into VN species enhances the adsorption energy of vanadium sites for oxygen molecules.The*OOH dissociation transitions from being unspontaneous on the VN surface to a spontaneous state on the S-doped VN surface.Then,the ORR barrier on the S-VN/co.NS-MC surface is reduced.The S-VN/co.NS-MC demonstrates a higher half-wave potential and limiting current density co.pared to the VN/co.N-MC.The S-VN/co.NS-MC-based liquid ZABs display a power density of 195.7 m W cm^(-2),a specific capacity of 815.7 m A h g^(-1),and a cycling stability exceeding 250 h.The S-VN/co.NS-MC-based flexible ZABs are successfully employed to charge both a smart watch and a mobile phone.This approach holds promise for advancing the co.mercial utilization of VN-based catalysts in ZABs.
