Advanced Materials, EarlyView.Van der Waals heterostructures offer exciting possibilities for artificial materials with unique optical, electronic, and spintronic properties. However, their use in the terahertz (THz) range is limited due to material constraints. This study demonstrates scalable, large‐area, crystalline 2D heterostructures, combining topological insulators ...

Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation
Advanced Materials, EarlyView.In this work, a universal metasurface multiplexing strategy is presented based on non‐injective transformation. By jointly optimizing two metasurfaces, multiplexed channels achieve independent wavefront control, overcoming crosstalk limits of single‐layer designs.

Research of the Transfer Method of Four-dimensional Coordinate to Three-dimensional Coordinate
Jixie chuandong, 2016 The coordinate measure machine（CMM） with rotary table is often use in the field of precision measurement.Because of the error evaluation requires that all measured point must be expressed in the same coordinate system,but the workpiece coordinate system ...

Fourth order superintegrable systems separating in Cartesian coordinates I. Exotic quantum potentials [PDF]
Journal of Physics A: Mathematical and Theoretical, 2017 A study is presented of two-dimensional superintegrable systems separating in Cartesian coordinates and allowing an integral of motion that is a fourth order polynomial in the momenta. All quantum mechanical potentials that do not satisfy any linear differential equation are found. They do however satisfy nonlinear ODEs.

Advanced Materials Interfaces, EarlyView.Friction force microscopy using diamond tips on epitaxial graphene supported by SiC(0001) shows a sharp friction increase. Silicon tips show similar behavior but at lower threshold forces. Atomistic simulations reveal three different friction regimes as normal pressure rises: graphene‐tip interfacial slip, graphene‐tip bonding, and a reversible ...

Advanced Materials Technologies, EarlyView.A low‐cost, maskless visible light photopatterning system has been developed by combining a consumer‐grade projector with a single Fresnel lens, generating the Fresnel Lens Integrated Projector (FLIP) system. FLIP enables flexible photopatterning of solid and gel films with features down to 30 µm and 135 µm, respectively.
