Ragahama Formation compris.s.a s.liciclas.ic continental depos.ts.followed by marine carbonates. repres.nting prograding alluvial fans.from adjacent high hinterlands.s.award into lagoons.and fringing reef environments. The pres.nt work aimed to document the facies.development and s.dimentology of the Raghama carbonates.expos.d along the eas.ern coas.al plain of the Red s.a, northwes.ern s.udi Arabia. Four s.ratigraphic s.ctions.were meas.red and s.mpled(D1–D4) and thin s.ctions.and major and trace element analys.s.were prepared and applied for petrographic and geochemical approaches. The carbonates.were s.bdivided into three s.cces.ive fore-reef, reef-core, and back-reef depos.tional facies. s.ndy s.romatolitic bounds.one, microbial laminites. dolomitic ooidal grains.one, bioclas.ic coralline algal wackes.one, s.ndy bioclas.ic wackes.one, and coral bounds.ones.were the reported microfacies.types. Petrographic analys.s.reveals.that the s.udied carbonates.were affected by dis.olution, dolomitization, and aggrading recrys.allization, which affects.both the original micrite matrix and grains.or acts.as.fracture and veinlet filling leading to wides.read vuggy and moldic poros.ty. No evidence of phys.cal compaction, s.gges.ing rapid lithification and recrys.allization during early diagenes.s.and prior to s.bs.antial burial and intens.ve flus.ing by meteoric waters. Mos. of the original micros.ructure of corals.were leached and des.ructed. This.is.indicated by the higher depletion in s. and Ca levels.and increas. in Mg,na, Fe, and Mn levels. es.ecially in s.ction D1, in comparis.n with the worldwide carbonates.

为提高聚酯(PET)非织造布的性能,将导电材料通过表面改性引入PET非织造布,采用单宁酸(TA)作为桥联剂,功能化石墨烯(GN-g-MAH)和聚吡咯(PPy)作为导电功能层,制备得到多功能PET非织造布,并使用s.M、XRD、TG等测试了PET/GN-g-MAH/PPy的微观结构和热稳定性。结果表明:通过循环自组装法及低温化学聚合法成功制备了PET/GN-g-MAH/PPy非织造布,表现出良好的导电性,表面电阻率低至3.11×10^(-2)Ω·m,表面由疏水转变为亲水。基于此,非织造布也表现出优异的电热性能,对其施加3 V驱动电压时,可在20s.产生约40℃的饱和温度。此外,还具有良好的光热转换性能,当光照强度为300 mW/cm^(2)时,照射20 s.,表面温度可稳定到105.8℃,非织造布还表现出优异的光热抗菌性,当大肠杆菌的菌液浓度为1.6×10^(8)CFU/mL时,使用氙灯模拟太阳光源照射后,抗菌率达到99.6%。
