Graphene nanoplatelets (GNP) is a newly nanomaterial with extraordinary properties. This paper investigated the effect of GNP on addition freeze–thaw (F–T) resistance concrete. In this experimental study, water to cement ratio remained unchanged, control mixture without materials and was ranging from 0.02% 0.4% by weight ordinary Portland prepared. Specimens were carried out rapid freeze-thaw test, according current Chinese standard. The workability, compressive strength, visual...

To achieve accurate color prediction of full-color gamut blended yarns, this paper constructs a grid mixing model based on four primary fibers: magenta, cyan, yellow, and gray. The Friele algorithm was reconstructed by associating the parameters with wavelength blending concentrations. Next, 112 training samples 7 validation were planned in gridded to be used for sample preparation reflectance testing. Then, divided into 9 regions, optimal obtained using assignment iteration method at 31...

Presented here is a simple and robust approach for the integration of mixed-scale (nm-cm) structures into fluidic devices. We report on devices composed large-area polymer nanopillar arrays high aspect ratio (33-667) integrated microfluidic channels fabricated by cast-molding polymerization methyl methacrylate with mechanically/lithographically patterned, nanoporous aluminium oxide (AAO) templates. The microchannels containing can be chemically functionalized used variety applications, such...

Climate change has been unprecedented in the past decades or even thousands of years, which had an adverse impact on mechanical properties concrete structures. Many researchers have begun to study new materials. Graphene nanoplatelet (GNP) is attractive nanomaterial that can crystal structure and improve durability. The aim present was investigate effect GNP (0.05%wt) carbonation depth under simulated changing climate conditions (varying temperature, relative humidity, carbon dioxide (CO2)...

This study investigates an adaptive chattering-free sliding-mode control method for n-order nonlinear systems with unknown external disturbances and uncertain models. The proposed takes the advantage of finite-time fast convergence to avoid singularity problem ensure its robustness against system uncertainty disturbance. To achieve from any initial condition origin, a full-order terminal controller containing differential terms is based on property systems. Then continuous smooth actual law...

We have performed a systematic experimental study of electrokinetic mobility depending on the mobile phase ionic strength (concentration Tris buffer) using different, well-defined porous and, for reference behavior, nonporous silica-based spherical microparticles. Effects both an intraparticle electrical double layer overlap and porosity electrophoretic in dilute suspensions electroosmotic fixed beds devised (non)porous particles were investigated. The electrokinetically consistent results...

Three-dimensional, free-standing polymer nanopillars with ultrahigh aspect ratios fabricated via a template-synthesized approach can be readily functionalized while maintaining their structural integrity to provide high-surface-area scaffolds for biomolecule attachment. The in patterns over large areas and integrated microfluidic networks subsequently elaborated chemical biological functionalities.

Abstract The mortar loses strength under acid rain conditions, causing cracking, weight loss and damage to the structure. This paper studies effects of graphenene nanoplatelets(GNP) simulated conditions. A control sample without GNP addition were ranging from 0.2% 0.6% by ordinary Portland cement prepared. In different corrosion days, mechanical properties measured, scanning electron microscopy also applied. Results showed that added with graphene are improved. Compared sample, compressive...

Emergence of the intertidal midge, Pontomyia oceana Tokunaga, 1964, occurred semilunarly in southern Taiwan. The mean emergence time, or capture was concentrated within 1–2 h each evening, but varied by 4–6 relative to sunset and low tide on different evenings. We used light treatments investigate whether an endogenous clock involved. Three light-dark (LD) cycles were necessary for entrainment population. Once entrained, midges retained rhythm, with a period 24.5–25.0 h, several days without...

Cross-border e-commerce has gradually emerged with the popularity of Internet in world. It represents a new business model e-commerce. The public is still same as daily shopping on platforms. However, cross-border can be divided into two parts at home and abroad. With continuous emergence social models such Metaverse, data generated by online networking becoming larger larger, science developed accordingly, effective use become key to rapid development various industries. Big technology...

P2.5 plug-in hybrid electric vehicles (P2.5-PHEVs) exhibit high transmission efficiencies and no power interruption in the shifting mode switching process; thus, they have broad application prospects. The a PHEV under pure startup does not entail clutch, initial torque of motor is often set condition that maximum allowable slope should lead to backward sliding, which leads problems excessive jerk small-slope catapulting when occurs downhill. optimal method different torques according...

Considering intense hydrothermal activities and rugged topography in a near-bottom environment of the trans-Atlantic geotraverse (TAG) mound, small autonomous underwater vehicle (S-AUV) will suffer from time-varying disturbances, model uncertainties, actuator faults, input saturations. To handle these issues, fault-tolerant adaptive robust sliding mode control method is presented this paper. Firstly, unknown faults S-AUV are synthesized into lumped uncertain vector. Without requiring upper...
