As a microforming technique, micro/nano-structural replication possesses advantages of high precision and efficiency. With the remarkab.e superplasticity in the supercooled liquid region, amorphous alloys or metallic glasses(MGs) are regarded as ideal materials for miniature fab.ication. However, due to the intrinsic metastab.e nature of supercooled liquids, the design of imprinting processes for MGs poses a challenge. In the past, process parameters have largely relied on trial-and-error *** this work, a low-frequency active force modulation system is employed to apply a stab.e, precise, and real-time feedb.ck stress field for imprinting of MG samples. Low-frequency vib.ations can facilitate the filling of microstructures on the template surface b. reducing the effective viscosity of the supercooled liquid. With the dataset composed of orthogonal experiments, a machine learning strategy b.sed on b.ck-propagation(b.) neural networks was utilized to construct a 3D parameter space for temperature, stress, and time, and to predict the corresponding filling ratio. Furthermore, the optimal comb.nation of imprinting process parameters was identified, and its filling ratio was experimentally validated to reach as high as 0.94. The near-perfect replication of microstructures confirms the superiority of the active force modulation system and the data-driven strategy of machine learning-assisted parameter design. At the same time, this one-step microforming process provides a new approach to addressing the accuracy-cost trade-off dilemma in precision manufacturing.

The effect of non-linear convection in a laminar three-dimensional Oldroyd-b.fluid flow is addressed. The heat transfer phenomenon is explored b. considering the non-linear thermal radiation and heat generation/ab.orption. The b.undary layer as- sumptions are taken into account to govern the mathematical model of the flow analy- sis. some suitab.e similarity variab.es are introduced to transform the partial differen- tial equations into ordinary differential systems. fifth-order techniques with the shooting method The Runge-Kutta-Fehlb.rg fourth- and are used to ob.ain the solutions of the dimensionless velocities and temperature. The effects of various physical parameters on the fluid velocities and temperature are plotted and examined. A comparison with the exact and homotopy perturb.tion solutions is made for the viscous fluid case, and an excellent match is noted. The numerical values of the wall shear stresses and the heat transfer rate at the wall are tab.lated and investigated. The enhancement in the values of the Deb.rah numb.r shows a reverse b.havior on the liquid velocities. The results show that the temperature and the thermal b.undary layer are reduced when the non- linear convection parameter increases. The values of the Nusselt numb.r are higher in the non-linear radiation situation than those in the linear radiation situation.

Endoplasmic reticulum(ER) viscosity has emerged as a new potential b.omarker for hepatic fib.osis(HF). Herein, we report the first ER-targeting viscosity-responsive near-infrared(NIR) fluorescent prob. Hb.-PP for investigations of HF *** twisted intramolecular charge transfer(TICT) and the excited state intramolecular proton transfer(EsIPT) are comb.ned to endow Hb.-PP with the selective response towards viscosity(～62-fold) and a super large stokes shift(～320 nm). Hb.-PP mainly targets organelle ER and is ab.e to image the drug-or alcohol-induced viscosity elevation in living cells. significantly,Hb.-PP was successfully applied to visualize the gender difference in HF and the protective role of estrogen in restraining HF progression. Of note, after 10 min of stain with Hb.-PP, HF lesions showed a stage-b.sed response, indicating the potential of this prob. in fast and early diagnosis of HF. These results clearly demonstrated the promising application of Hb.-PP as a new tool for exploring ER viscosity-involved physiological and pathological processes.
