UV Light

A group of researchers has advocated for the use of UV light as a ‘particularly efficient, easily deployable, and economically affordable’ means to limit the spread of coronavirus. The study, involved experts in the fields of virology, immunology, aerosols, architecture, and physics, analyses the possible methods to prevent Sars-Cov-2 propagation in indoor spaces. Small indoor [..]

NMR Spectroscopy

Noninvasive evaluation of the spatial distribution of chemical composition and diffusion behavior of materials is becoming possible by advanced nuclear magnetic resonance (NMR Spectroscopy) pulse sequence editing. However, there is room for improvement in the spectral resolution and analytical method for application to heterogeneous samples. Here, researchers develop applications for comprehensively evaluating compounds and their [..]

Thermal Scanner

A multi-person thermal scanner accurately reads the skin temperature of up to six people at once. The scanner’s primary function will be to help healthcare organizations like the NHS and businesses quickly and efficiently detect individuals who are carrying a fever – one of the primary symptoms of Covid-19. The Multi-Person Thermal Scanner is a [..]

Flexible Electronics

Researchers have demonstrated the strong potential for recyclable, flexible electronics to be used in creating cheaper solar cells, touchscreens, wearable ‘e-skins’, and next-generation responsive windows. These materials, made using a simple, cost-effective fabrication process, could replace traditional transparent conductive oxides such as indium tin oxide (ITO), which is a necessary component of almost all thin-film [..]

Super Resolution Microscope

Centrioles are about 100 times smaller than a mammalian cell, and a thousand times smaller than a human hair. So, observing them inside of living cells required improving super resolution microscope technology that uses light to probe specimens, since the methods tend to be too slow for structural studies. Dora Mahecic, a Ph.D. student in [..]

3D Printing Technique Uses Microfluidics

Engineers have developed a new 3D printing technique that allows printing of finely tuned flexible materials. By using a droplet-based, multiphase microfluidic system, the team was able to efficiently print materials with potential applications in soft robotics, tissue engineering, and wearable technology. In traditional extrusion-based 3D printers, printing material is pushed through a nozzle and [..]

CT Scan

The tree of life is rich in examples of species that changed from living in water to a land-based existence. Occasionally, some species took the opposite direction. New insights, provided by a CT scan, into the anatomy of the inner ear of prehistoric reptiles, the thalattosuchians, revealed details about one of these evolutionary turning points. [..]

Fast Fabrication - Optical Chips

The modern photonics industry is constantly working on making its devices more compact, be it computing systems or sensors and lidars. For this, it is necessary to make lasers, transistors, and other elements smaller. A team of scientists proposed an affordable fast fabrication method to create optical chips right in a Petri dish. Using devices [..]

Glass Display Coating

Apple’s new patent relates to further strengthening both the cover glass display and structural housing glass of future iPhones and other devices like a possible future all-glass iMac. Apple notes that while it may be desirable to coat glass structures with anti-scratch and anti-reflection coatings, they create stress concentrations that make the glass structure susceptible [..]

Bionic Eye Night Vision

A team of scientists has developed what they call the Electrochemical Eye (EC-Eye) – bionic eye. Rather than using a two-dimensional image sensor like a camera, the EC-Eye is modeled after a real retina with a concave curve. This surface is studded with an array of tiny light sensors designed to mimic the photoreceptors on [..]

Silicon in Optoelectronics

Silicon is the main material in electronic engineering. All information and computing technologies that play a key role in modern civilization are based on silicon: computers, communications, astronautics, biomedicine, robotics, and much more. The main stumbling block on the way to increasing the speed of integrated circuits is the limited speed of electrical signal propagation [..]

Light Sensitivity

Photoreceptor degeneration is an important cause of blindness. Enabling near-infrared light sensitivity in a blind human retina may supplement or restore visual function in patients with regional retinal degeneration. Researchers induced near-infrared light sensitivity using gold nanorods bound to temperature-sensitive engineered transient receptor potential (TRP) channels. When the nanorods absorbed light and converted it into [..]

Fluorescent Dyes

US scientists have developed a molecular shield that stabilizes near-infrared fluorescent dyes and enhances their functionality. Fluorescence bioimaging often uses the near-infrared light region because this radiation can efficiently penetrate human tissue. Fluorescent dyes designed for this purpose usually have a flat, symmetrical molecular architecture, which favors absorption of near-infrared light, but the dyes also [..]

Deep Learning Medical Imaging

As artificial intelligence (AI) becomes increasingly used for critical applications such as diagnosing and treating diseases, predictions and results regarding medical care that practitioners and patients can trust will require more reliable deep learning medical imaging models. A team of computer scientists proposes a novel deep learning approach aimed at improving the reliability of classifier [..]

Optical Data Storage

Magnetic tape and hard disk drives hold much of the world’s archival data. Compared with other memory and storage technologies, optical data storage in tape and disk drives cost less and are more reliable. Archivists may soon have another option—using an extremely fast laser to write data into a 2-millimeter-thick piece of glass, roughly the [..]

Circuit Technology

Researchers have developed a new way to build power efficient and programmable integrated switching units on a silicon photonics chip. The new circuit technology is poised to reduce production costs by allowing a generic optical circuit to be fabricated in bulk and then later programmed for specific applications such as communications systems, LIDAR circuits or [..]
