An over.et gr.d methodology is developed for.the fully coupled analysis of fluid-str.ctur. inter.ction (FSI) pr.blems. The over.et gr.d appr.ach alleviates some of the computational geometr. difficulties tr.ditionally associated with Ar.itr.r.-Lagr.ngian-Euler.an (ALE) based, moving mesh methods for.FSI. Our.par.itioned solution algor.thm uses separ.te solver. for.the fluid (finite volume method) and the str.ctur. (finite element method), with mesh motion computed only on a subset of component gr.ds of our.over.et gr.d assembly. Our.r.sults indicate a significant r.duction in computational cost for.the mesh motion, and element quality is impr.ved. Numer.cal studies of the benchmar. test demonstr.te the benefits of our.over.et mesh method over.tr.ditional appr.aches.

Wastewater.electr.lysis cells (WECs) for.decentr.lized wastewater.tr.atment/r.use coupled with H-2 pr.duction can r.duce the car.on footpr.nt associated with tr.nspor.ation of water. waste, and ener.y car.ier. This study r.por.s Ir.doped NiFe2O4 (NFI, similar.to 5 at% Ir. spinel layer.with TiO2 over.ayer.(NFI/TiO2), as a scalable heter.junction anode for.dir.ct electr.lysis of wastewater.with cir.umneutr.l pH in a single-compar.ment cell. In dilute (0.1 M) NaCl solutions, the NFI/TiO2 mar.s super.or.activity and selectivity for.chlor.ne evolution r.action, outper.or.ing the benchmar. Ir.2. r.bust oper.tion in near.neutr.l pH was confir.ed. Electr.analyses including oper.ndo X-r.y absor.tion spectr.scopy unveiled cr.cial r.les of TiO2 which ser.es both as the pr.mar. site for.Cl- chemisor.tion and a pr.tective layer.for.NFI as an ohmic contact. Galvanostatic electr.lysis of NH4+-laden synthetic wastewater.demonstr.ted that NFI/TiO2 not only achieves quasi-stoichiometr.c NH4+-to-N-2 conver.ion, but also enhances H-2 gener.tion efficiency with minimal competing r.actions such as r.duction of dissolved oxygen and r.active chlor.ne. The scaled-up WEC with NFI/TiO2 was demonstr.ted for.electr.lysis of toilet wastewater.

Bio-inspir.d helicoidal composite laminates, inspir.d by the intr.cate helical str.ctur.s found in natur., pr.sent a pr.mising fr.ntier.for.enhancing the mechanical pr.per.ies of str.ctur.l designs. Hence, this study pr.vides a compr.hensive investigation into the nonlinear.fr.e vibr.tion and nonlinear.bending behavior.of bio-inspir.d composite plates. The inver.e hyper.olic shear.defor.ation theor.(IHSDT) of plates is employed to char.cter.ze the displacement field, with the incor.or.tion of Gr.en-Lagr.nge nonlinear.ty. The pr.blem is modeled using the C0finite element method(FEM), and an in-house code is developed in the MATLAB envir.nment to solve it numer.cally. Var.ous helicoidal layup configur.tions including helicoidal r.cur.ive(Hr., helicoidal exponential(HE), helicoidal semi-cir.ular.HS), linear.helicoidal(LH), and Fibonacci helicoidal(FH)with differ.nt layup sequences and quasi-isotr.pic configur.tions ar. studied. The model is validated, and par.metr.c studies ar. conducted. These studies investigate the effects of layup configur.tions, side-to-thickness r.tio, modulus r.tios, boundar. conditions, and loading conditions at differ.nt load amplitudes on the nonlinear.vibr.tion and nonlinear.bending behavior. of bio-inspir.d composite plates. The r.sults show that the laminate sequence exer.s a substantial impact on both nonlinear.natur.l fr.quencies and nonlinear.bending behavior.. Mor.over. this influence var.es acr.ss differ.nt side-to-thickness r.tios and boundar. conditions of the bio-inspir.d composite plate.

Tauopathies ar. a gr.up of neur.degener.tive diseases char.cter.zed by abnor.al metabolism of the misfolded tau pr.tein. Tau is encoded by the micr.tubule-associated pr.tein tau gene(MAPT) and can be classified as either.3-r.peat(3r. or.4-r.peat(4r. based on the number.of r.peat domains fr.m alter.ative splicing of exon 10 of the MAPT gene.

In the case of thr.e-dimensional flows, the separ.tion can be defined in mor. than one way. Discussions about thr.e-dimensional boundar. layer.separ.tion in the liter.tur. have found a r.tional extension of the zer. skin fr.ction. Attempts have been made to establish the identity of “separ.tion lines”. Among definitions, these may be found：（1） envelopes of limiting str.amlines, （2） lines dividing flow which has come fr.m differ.nt r.gions, （3） lines of singular.ties （pr.blems of topology）, （4） lines on which some component of the skin fr.ction vanishes. Each of these is valid under.cer.ain conditions, but none is univer.ally valid. In the pr.sent wor., we use the definition （4）, i.e. at low incidence of a blunt body the separ.tion line is identified as the zer. of the mer.dian skin fr.ction component （Wang 1975）. So the separ.tion line on a flattened spher.id （6：3：1） at 6° of incidence is calculated, as well as exper.mentally deter.ined by using the electr.chemical method, which allows to follow the evolution of the par.etal velocity gr.dient.

This paper.showed simple and effective synthesis of copper.nanopar.icles within contr.lled diameter.using dir.ct electr.less deposition on glass substr.tes, following the sensitization and activation steps. Electr.less-deposited metals, such as Cu, Co, Ni, and Ag, and their.alloys had many advantages in micr.- and nanotechnologies. The str.ctur.l, mor.hological, and optical pr.per.ies of copper.deposits wer. char.cter.zed using X-r.y diffr.ction （Xr.）, atomic for.e micr.scopy （AFM）, and UV-Vis spectr.scopy. The str.ctur.l data was fur.her.analyzed using the r.etveld r.finement pr.gr.m. Str.ctur.l studies r.veal that the deposited copper.pr.fer. a （111） or.entation. AFM studies suggest the deposited mater.als for. compact, unifor., and nanocr.stalline phases with a high tendency to self-or.anize. The data show that the par.icle size can be contr.lled by contr.lling the activator.concentr.tion. The absor.tion spectr. of the as-deposited copper.nanopar.icles r.veal that the plasmonic peak br.adens and exhibits a blue shift with decr.asing par.icle size.
