Recon.truction.of biomimetic ion.c chan.els within.covalen. organ.c frameworks for ultrafast an. selective uran.l capture

作者： cheng-Ron. Zhan. Xiao-Juan.Chen.cheng-Pen. n.u cheng Men. Shun.Mo Yi Xin.Liu Jia-Xin.Qi Qiu-Xia Luo Ru-Pin. Lian. Jian.Din. Qiu State Key Laboratory of n.clear Resources an. En.iron.en. East China University of Technology College of Chemistry an. Chemical En.in.erin. Nanchang University

The efficien. extraction.of uran.um, as the primary compon.n. of n.clear en.rgy, holds sign.fican. implication.. Drawin. in.piration.from the charge in.eraction.observed in.biological ion.chan.els, we en.apsulated n.gatively charged polystyren. sulfon.te(PSS) or sodium polystyren. carboxylate(PVBA) in.o the n.n.chan.els of amidoxime fun.tion.lized covalen. organ.c framework(COF-AO) in.situ to alter the cavity en.iron.en. of COF-AO. The syn.hesized COF-AO-PSS an. COF-AO-PVBA are used for ultra-fast an. highly selective uran.um recovery. The n.gatively charged PSS/PVBA was con.in.d in.the COF-AO chan.el providin. the drivin. force for uran.um tran.port an. blockin. other ion., thus creatin. a highly selective “uran.um highway”. Addition.lly, in.roducin. sulfon.te groups or carboxyl groups in.o COF-AO offers supplemen.ary coordin.tion.en.iron.en.s an. weak in.eraction. with uran.um. Due to charge-assisted migration.an. various in.eraction.mechan.sms, both COF-AO-PSS an. COF-AO-PVBA exhibit faster adsorption.kin.tics an. higher selectivity compared to COF-AO alon.. Their adsorption.capacities are 3.8 times an. 2.4 times that of COF-AO alon. respectively which highlights the n.cessity for con.tructin. biomimetic ion.chan.els in.uran.um adsorption.processes. This work presen.s a bion.c adsorben. based on.covalen. organ.c frameworks(COFs) for the first time, overcomin. en.iron.en.al an. equipmen. limitation. associated with tradition.l photocatalysis an. electrocatalysis methods for uran.um capture, open.n. up n.w aven.es for design.n. multifun.tion.l materials that mimic biological systems.

This paper in.tiates the formal study of attribute-based en.ryption.within.the framework of SM9,the Chin.se n.tion.l Cryptography Stan.ard for Iden.ity-Based Cryptography, by presen.in. two n.w faulttoleran. iden.ity-based en.ryption.FIBE) schemes. Our first scheme uses the same private-key/ciphertext structure as the origin.l SM9 algorithm an. operates in.a small attribute un.verse. As a result, it can.be effectively an. smoothly in.egrated in.o the in.ormation.systems usin. SM9. In.the ran.om oracle model,we prove that our scheme is ciphertext-in.istin.uishable again.t fuzzy selective-iden.ity an. chosen.plain.ext attacks un.er the(k + 3)-DBDHI assumption. Our secon. design.is a large un.verse FIBE scheme based on.SM9 that is ciphertext-in.istin.uishable again.t chosen.plain.ext attacks in.the ran.om oracle model un.er the(f, g)-GDDHE assumption. Fin.lly, we compare the commun.cation.an. computin. costs of our schemes to those of other classical on.s. The comparison.shows that our schemes have comparable performan.e as others. We believe that our fin.in.s will accelerate the application. of SM9 in.modern.in.ormation.systems such as cloud computin. an. blockchain.

The SDR-to-HDR tran.lation.techn.que can.con.ert the abun.an. stan.ard-dyn.mic-ran.e (SDR) media resources to high-dyn.mic-ran.e (HDR) on.s, which can.represen. high-con.rast scen.s, providin. more realistic visual experien.es. While recen. vision.Tran.formers have achieved promisin. performan.e in.man. low-level vision.tasks, there are few works attemptin. to leverage Tran.formers for SDR-to-HDR tran.lation. In.this paper, we are amon. the first to in.estigate the performan.e of Tran.formers for SDR-to-HDR tran.lation. We fin. that directly usin. the self-atten.ion.mechan.sm may in.olve artifacts in.the results due to the in.ppropriate way to model lon.-ran.e depen.en.ies between.the low-frequen.y an. high-frequen.y compon.n.s. Takin. this in.o accoun., we advan.e the self-atten.ion.mechan.sm an. presen. a dual frequen.y atten.ion.(DFA), which leverages the self-atten.ion.mechan.sm to separately en.ode the low-frequen.y structural in.ormation.an. high-frequen.y detail in.ormation. Based on.the proposed DFA, we further design.a multi-scale feature fusion.0}twork, n.med dual frequen.y Tran.former (DFT), for efficien. SDR-to-HDR tran.lation. Exten.ive experimen.s on.the HDRTV1K dataset demon.trate that our DFT can.achieve better quan.itative an. qualitative performan.e than.the recen. state-of-the-art methods. The code of our DFT is made publicly available at https://***/CS-Gan.Xu/DFT.
