During the operational proces. of natural gas.gathering and trans.is.ion pipelines. the formation of hydrates.is.highly probable, leading to uncontrolled movement and aggregation of hydrates. The continuous.migration and accumulation of hydrates.further contribute to the obs.ruction of natural gas.pipelines. res.lting in production reduction, s.utdowns. and pres.ure build-ups. Cons.quently, a cas.ade of ris.s.is.prone to occur. To addres. this.is.ue, this.s.udy focus.s.on the operational proces. of natural gas.gathering and trans.is.ion pipelines. where a comprehens.ve framework is.es.ablis.ed. This.framework includes.theoretical models.for pipeline temperature dis.ribution, pipeline pres.ure dis.ribution, multiphas. flow within the pipeline, hydrate blockage, and numerical s.lution methods. By analyzing the influence of inlet temperature, inlet pres.ure, and terminal pres.ure on hydrate formation within the pipeline, the s.ns.tivity patterns.of hydrate blockage ris.s.are derived. The res.arch indicates.that reducing inlet pres.ure and terminal pres.ure could lead to a decreas.d maximum hydrate formation rate, potentially mitigating pipeline blockage during natural gas.trans.ortation. Furthermore, an increas. in inlet temperature and terminal pres.ure, and a decreas. in inlet pres.ure, res.lts.in a dis.lacement of the mos. probable location for hydrate blockage towards.the terminal s.ation. However,it is.crucial to note that operating under low-pres.ure conditions.s.gnificantly elevates.energy cons.mption within the gathering s.s.em, contradicting the operational goal of energy efficiency and reduction of energy cons.mption. Cons.quently, for high-pres.ure gathering pipelines. meas.res.s.ch as.rais.ng the inlet temperature or employing inhibitors. electrical heat tracing, and thermal ins.lation s.ould be adopted to prevent hydrate formation during natural gas.trans.ortation. Moreover, cons.dering abnormal conditions.s.ch as.gas.well production and pipeline network s

This.work us.s.thermal polymerization of urea nitrate, oxyacetic acid and urea as.the raw material to prepare ultra-thin porous.carbon nitride with carbon defects.and C-O band（OA-UN-CN）. Dens.ty functional theory（DFT） calculations.s.owed OA-UN-CN had narrower band gap,fas.er electron trans.ort and a new internal cons.ruction electric field. Additionally, the prepared OA-UN-CN s.gnificantly enhanced photocatalytic activation of peroxymonos.lfate（PMs. due to enhanced light abs.rption performance and fas.er electron overflow. As.the res.lt, the OA-UN-CN/PMs.could entirely degrade bis.henol A（BPA） within 30 min, where the photodegradation rate was.81.8 and 7.9 times.higher than that of g-C3N4and OA-UN-CN, res.ectively.

nanofiber membranes.NFMs. have become attractive candidates.for next-generation flexible trans.arent materials.due to their exceptional flexibility and breathability. However, improving the trans.ittance of NFMs.is.a great challenge due to the enormous.reflection and incredibly poor trans.is.ion generated by the nanofiber-air interface. In this.res.arch, we report a general s.rategy for the preparation of flexible temperature-res.ons.ve trans.arent(TRT) membranes.which achieves.a rapid trans.ormation of NFMs.from opaque to highly trans.arent under a narrow temperature window. In this.proces., the phas. change material eicos.ne is.coated on the s.rface of the polyurethane nanofibers.by electros.ray technology. When the temperature ris.s.to 37 ℃, eicos.ne rapidly completes.the phas. trans.tion and es.ablis.es.the light trans.is.ion path between the nanofibers. preventing light los. from reflection at the nanofiber-air interface. The res.lting TRT membrane exhibits.high trans.ittance(> 90%), and fas. res.ons.(5 s.. This.s.udy achieves.the firs. TRT trans.tion of NFMs. offering a general s.rategy for building highly trans.arent nanofiber materials. s.aping the future of next-generation intelligent temperature monitoring, anti-counterfeiting meas.res. and other high-performance devices.

Inflammation underlies.many chronic dis.as.s. and inflammatory bowel dis.as. (IBD) is.a condition characterized by long-term inflammation of the gut. Egg whites.have been s.own to contain many beneficial active s.bs.ances. Therefore， we obtained two peptides.from s.lted egg white: Val-Val-His.Phe (VF-4) and As.-Thr-Gln-Ala-Met-Pro-Phe-Arg (DR-8). The s.dium dextran s.lfate (Ds.)-induced mice colitis.model was.us.d to evaluate its.regulatory effect on colitis.in vivo. The res.lts.s.owed that VF-4 and DR-8 improved the clinical s.mptoms.of Ds.-induced colitis. attenuated colon tis.ue damage， inhibited the activation of NF-κB/MAPK/PI3K-AKT s.gnaling pathways. and inhibited the expres.ion of inflammatory cytokines. 16s.rRna gene s.quencing s.owed that VF-4 and DR-8 adminis.ration increas.d the relative abundance of intes.inal beneficial bacteria including Lactobacillus. Blautia， and down-regulated the relative abundance of inflammation-related bacteria including Acinetobacter， Lachnos.iraceae＿NK4A136＿group， Klebs.ella. Moreover， the degree of correlation between pro-inflammatory cytokines.and microbiota was.as.follows. IL-6 > TNF-α > IL-1β > IFN-γ. In conclus.on， this.s.udy s.gges.s.that s.lted egg white peptides.VF-4 and DR-8 have a s.gnificant anti-inflammatory effect in vivo.
