authorElsa Lani, Aloka SinhaabstractAt present, the progress in developing new liquid crystal materials for next-generation applications mainly focuses on improving the physical properties of liquid crystal systems.Recent research progress has shown that functionalized nanoparticles embedded in LC matrix can significantly alter the properties of LC materials based on the interaction between host m...
The emergence of ultrafast laser pulses marks an important milestone in laser science, triggering astonishing progress in a wide range of disciplines such as industrial applications, energy technology, and life sciences. Among various laser platforms that have been developed, fiber optic femtosecond oscillators are highly praised for their compact design, excellent performance, and cost-effectiven...
Scientists at Purdue University in the United States have developed a new type of two-photon polymerization technology. This technology cleverly combines two lasers and utilizes 3D printing technology to print complex high-resolution 3D structures while reducing femtosecond laser power by 50%. It helps to reduce the cost of high-resolution 3D printing technology, thereby further expanding its appl...
Main author: Yanming Zhang, Wentao Yana*The first unit: National University of SingaporePublished Journal: Acta MaterialiaResearch backgroundIndustry pain point: Although laser powder bed melting (LPBF) technology can manufacture complex components, the lack of consistent product quality is still the core bottleneck restricting its industrial application. Research has shown that up to 35% of proce...
The current deep neural network system (such as ChatGPT) can quickly improve energy efficiency by 100 times in training, and "future improvements will greatly increase by several orders of magnitude. Scientists from MIT and other institutions have demonstrated a new optical neural network training method that can crush state-of-the-art electronic microprocessors.Moreover, the computational density...
