When two mesh screens or fabrics are overlapped with a slight offset, moiré patterns emerge as a result of interference caused by the misalignment of the grids. While these patterns are commonly ...

A moiré pattern appears when you stack and rotate two copies of an image with regularly repeating shapes, turning simple patterns of squares or triangles into a groovy wave pattern that moves across ...

Fresnel zone plates (FZPs) are widely used for X-ray focusing and imaging thanks to their compactness and high resolution compared to refractive or mirror-based X-ray optics. However, achieving high ...

Ball Aerospace & Technologies Corp. has demonstrated unprecedented telescope technologies using ultra-lightweight polymer membrane optics. Ball is incrementally demonstrating technology needed to ...

Researchers with the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have created an innovative method to visualize and analyze atomic structures ...

Phasons, low-temperature quasiparticles found in crystal lattices, help interlayer excitons move at ultra-low temperatures, offering insights for materials science and potential boosts to quantum tech ...

Twistronics is a field of study that emerged from the intersection of nanotechnology and materials science. It involves manipulating the electronic properties of two-dimensional (2D) layered materials ...
