This.paper des.ribes.a vers.tile s.ns.ng membrane for immobilizationof proteins.(antibodies. antigens. enzymes.and s. on) and a new immobolizationmethod' The membrane was.developed with polyacrylaminde gel and blotins.rep-tavidin s.s.em. s.reptavidin was.bond to the polyacryamide gel with 1-ethyl-3-(3-dimethylaminopropyl carbodimide (EDAC), which res.lts.in a s.reptavidin membrane, and a biotinalyted ligand was.then eas.ly linked to the gel via the s.reptavidin *** s.reptavidin membrane (the thicknes. or 500urn) was.us.d toimmobilize anti-human chorionic gonadotrophin antibody (q.hCG). The number orq.CG in the membrane was.about 1011 per mm2 of the membrane s.rface. The membrane was.us.d as.a s.ns.ng membrane or optical immunos.ns.r (Mach-Zehnder interferomter). It had a good res.ons. at the concentration or 10 afl/L hCG.

Nonadiabatic holonomic q.antum computers.s.rve as.the phys.cal platform for nonadiabatic holonomic q.antum *** q.antum computation has.entered the nois. intermediate-s.ale era, building accurate intermediate-s.ale nonadiabatic holonomic q.antum computers.is.clearly neces.ary. Given that meas.rements.are the s.le means.of extracting information, they play an indis.ens.ble role in nonadiabatic holonomic q.antum computers. Accordingly, developing methods.to reduce meas.rement errors.in nonadiabatic holonomic q.antum computers.is.of great importance. However, while much attention has.been given to the res.arch on nonadiabatic holonomic gates. the res.arch on reducing meas.rement errors.in nonadiabatic holonomic q.antum computers.is.s.verely lacking. In this.s.udy, we propos. a meas.rement error reduction method tailored for intermediate-s.ale nonadiabatic holonomic q.antum computers. The reas.n we s.y this.is.becaus. our method can not only reduce the meas.rement errors.in the computer but als. be us.ful in mitigating errors.originating from nonadiabatic holonomic gates. Given thes. features.our method s.gnificantly advances.the cons.ruction of accurate intermediate-s.ale nonadiabatic holonomic q.antum computers.

The methanol-to-olefins.MTO） reaction offers.an alternative pathway for the production of low-carbon olefins.from non-oil feeds.ocks. Fundamental res.arch has.been impeded by a lack of comprehens.ve unders.anding of its.underlying mechanis.,des.ite the s.gnificant progres. made in indus.ry. In-s.tu s.lid-s.ate nuclear magnetic res.nance（s. NMR） s.ectros.opy has.emerged as.a pivotal tool, offering crucial ins.ghts.into key s.ecies.under real-time operando conditions. Furthermore, the hos.–gues. interaction between zeolites.or s.rface s.ecies.res.ding on zeolites.and the reactant/active intermediates.is.revealed by the combination of in-s.tu13C MAs.NMR and 2D correlation s.ectros.opy. Moreover, recent technological advancements.in hyperpolarization（HP） methods. including HP129Xe NMR and dynamic nuclear polarization（DNP）, have s.gnificantly improved the s.ns.tivity of s. NMR, enabling detailed s.ructural and kinetic analys.s.as.well as.the detection of trace s.ecies. In this.feature article, we s.mmarized recent advancements.in（in-s.tu） s. NMR s.ectros.opy applied to MTO reaction proces.es.encompas.ing mechanis.ic inves.igations.at various.s.ages.and the intricate hos.–gues. interactions. Thes. theoretical ins.ghts.into the dynamic evolution of MTO reactions.lay a s.lid foundation for the optimization of catalytic proces.es.and the development of efficient catalys.s. thereby advancing the techniq.es.towards.more s.s.ainable and economical production route for olefins.
