A team of researchers turned to Raman spectroscopy to rapidly screen for and identify novel psychoactive substances (NPS), known commonly as “legal highs.” The approach will now enable statutory agencies to identify the actual substances contained within legal highs more quickly, thereby enabling more prompt public health messages to be issued out to communities.

A novel fabrication method has achieved a device-friendly nanocomposite thin film that produces circularly polarized light. The simple and cost-effective technology could aid disease monitoring and diminish the disruption caused by follow-up medical treatment for cancer survivors and other patients. Read more

Blindness caused by glaucoma, which affects the optic nerve, can be avoided if the disease is detected at an early stage of development. Despite diagnostic and therapeutic advances over the past 20 years, a significant proportion of patients with glaucoma still progress to blindness, often because of late diagnosis. Read more

Electrons are so 20th century. In the 21st century, photonic devices, which use light to transport large amounts of information quickly, will enhance or even replace the electronic devices that are ubiquitous in our lives today. But there’s a step needed before optical connections can be integrated into telecommunications systems and computers: researchers need to [..]

Laser diodes that are fabricated from the aluminum gallium indium nitride (AlGaInN) material system are emerging as a technology for defense and security applications. Conventional underwater communications, which are achieved acoustically, are often associated with very slow data rates and short reaches. They are also particularly susceptible to interception… Read more here

Scientists at the Virginia Tech Carilion Research Institute (Roanoke, VA) used fluorescence imaging to examine how retinal ganglion cells develop in a mouse model, discovering that the process is not as straightforward as previously thought. Retinal neurons associated with vision generate connections in the brain, and as the brain develops it strengthens and maintains some [..]

Electronic displays for integration with clothing and textiles are a rapidly developing field in the realm of wearable electronics. However, flexible LEDs designed to form part of an elastic or deformable coating for clothing or apparel – even displays specifically designed to be directly bio-compatible – still rely on a hard substrate on which to [..]

Materials that allow light to pass through without distortion are possible, according to a new set of calculations by an international team of researchers. When a light wave travels through free space, its intensity can be the same everywhere but as soon as it hits an obstacle, the wave is altered. Scattering and diffraction lead [..]

Tech companies are developing virtual reality to make money in the gaming and entertainment market, but a group of intellectuals believes that this new tech will one day be useful to treat mental disorders. Because the VR technology aims to make visual content more engaging and immersive, the researchers at King’s College figured that this [..]

Lasers have a wide range of uses, including as precision heat sources for welding, cutting, marking, forming, peening, hardening, and more recently, 3D printing. Precise energy deposition also makes lasers useful tools for research in high-energy-density science, particularly at very short pulse lengths and high peak intensities. In all of the materials-processing applications, the properties [..]

Syntec optics is manufacturing Polymer optics, Plastic injection moulding and biometrics devices and components by the diamond turning process. Diamond turning is an important process to create precision elements through diamond-tipped lathes or various other machine tools. In general, multiple lathes are used which are controlled by computers. However, diamond-tipped lathes are not particularly implemented [..]
