Clouds are typically known for their shades of white and gray, but every so often they put on a colorful display that looks ...
University of Utah researchers have demonstrated a new method of 3D printing that avoids the leaky seams that come with the ...
Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the “Poisson spot” to create stable patterns of light called “optical skyrmions”.

Laser-driven metajets show a path to fuel-free spacecraft thrust
A spacecraft that never runs out of fuel sounds like science fiction, but a team at Texas A&M University has taken a small, literal step toward that goal. In experiments conducted at the university’s ...
Researchers developed a holographic data storage approach that stores and retrieves information in three dimensions by combining the amplitude, phase and polarization properties of light.Xiaodi Tan, ...
Abstract: Photolithography has a resolution limit of the incident wavelength that is generated by the diffraction of light. Surface plasmon (SP) is a recently proposed nanolithography technology that ...
Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...
Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is found in conventional systems. In conventional antiferromagnets, the ...
A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...

3D printing a diffraction pattern
Is it possible to 3d print a diffraction pattern? Trump’s supporters are starting to turn on him as his approval falls Dentist calls police on Aussie mom during ...
Researchers have developed a blueprint for weaving hopfions—complex, knot-like light structures—into repeating spacetime crystals. By exploiting two-color beams, they can generate ordered chains and ...
