Abstract Kirigami, with facile and automated fashion of three-dimensional (3D) transformations, offers an unconventional approach for realizing cutting-edge optical nano-electromechanical systems. Here, we demonstrate on-chip electromechanically reconfigurable nano-kirigami functionalities. The system is built on Au/SiO 2 /Si substrate operated via attractive electrostatic forces between the top gold nanostructure bottom silicon substrate. Large-range like 3D deformations are clearly...
Photocatalytic dehydrogenation of formic acid is a promising strategy for H2 generation. In this work, we report the use crystalline iron phosphide (FeP) nanoparticles as an efficient and robust cocatalyst on CdS nanorods (FeP@CdS) highly photocatalytic dehydrogenation. The optimal evolution rate can reach ∼556 μmol·h–1 at pH 3.5, which more than 37 times higher that bare CdS. Moreover, photocatalyst demonstrates excellent stability; no significant decrease catalytic activity was observed...
The extremely cross-linked structure of the cured epoxy resin makes it fragile. This work toughened N,N-diglycidyl-4-glycidyloxyaniline (AFG-90H)/methyl nadic anhydride (MNA)/2-ethyl-4-methylimi-dazole (2E4MZ) matrix with different curing agent and resin. effects introduction methyl hexahydrophthalic (MeHHPA) bisphenol F-type (8220) on kinetics, heat resistance, mechanical properties casting body were investigated. modified was used to manufacture high-performance composites. characteristics...
Precise rheological properties of inks and slurries are essential to providing homogeneous, well controlled reproducible coatings, particularly in electrode manufacturing for batteries. The rheology can aid understanding the slurry structure, as optimisation process conditions create coatings with desired microstructure. shear is typically measured, however mixing coating steps contain significant extensional flows, this omits a part response. Here battery quantified using miniature...
Abstract Novel classical wave phenomenon analogs of the quantum spin Hall effect are mostly based on construction pseudo-spins. Here we show that non-trivial topology a system can also be realized using orbital angular momentum through coupling between and vector. The idea is illustrated with tight-binding model experimentally demonstrated transmission line network. We even very small network cluster exhibits momentum-dependent one-way topological edge states, their properties described in...
The symmetry dependences of plasmon excitation modes are studied in 3D silver nanorod trimers. degenerate split into chiral by breaking the inversion and mirror trimer through translation and/or rotation middle rod. With a operation, successive evolution circular dichroism (CD) spectrum can be achieved gradual symmetry. An additional operation produces even dramatic spectral changes due to quasi-mirror resulted from same angular distance rod top bottom rods. Especially, pairs new excited...
To improve sustainability of lithium-ion battery electrodes there is a need to design in recycling at the manufacturing stage.
Plasmonic structural colors have plenty of advantages over traditional based on colorants. The pulsed laser provides an important method generating plasmonic with high efficiency and low cost.
