Galaxy Evolution – Spectroscopy For Space Applications

One of the most widely used techniques to generate light through an efficient electron transfer is called electrochemiluminescence, or electrogenerated chemiluminescence (ECL). ECL mechanisms can be explored via ‘spooling spectroscopy’ in which individual ECL spectra showing emitted light are collected continuously during a potentiodynamic course. The obtained spectra are spooled together and plotted along the [..]

Uveal Melanoma – New Promising Treatment

A partnership between artificial intelligence systems and clinicians may lead to mutual advancements in glaucoma research and clinical practice, according to a review published in the British Journal of Ophthalmology. Given that glaucomatous changes to the optic nerve head tissues are irreversible, timely, and reliable structural and functional evaluation of the eye could help in [..]

Photocatalysts - Metal Laminations Improve Performance

Moth eye has inspired researchers to design a new, highly effective anti-reflective coating that could be useful for solar panels, smartphones, and tablet computers. These mainly nocturnal creatures have evolved eyes that are non-reflective to protect them from the notice of predators. The non-reflective nature of the moth eye arises because of the periodic nanoscale [..]

Uveal Melanoma – New Promising Treatment

Rochester researchers demonstrate a way to track the interactions of microscopic immune cells in a living eye without dyes or damage, a first for imaging science. Combining infrared videography (adaptive optics) and artificial intelligence, the new technique could be a ‘game-changer’ for some clinical diagnoses as well as for fields like pharmaceuticals. The researchers integrated [..]

Photocatalysts - Metal Laminations Improve Performance

Researchers employed Nafion as a solid medium for the fabrication of transparent luminescent materials with tunable emissions. These membranes are quite famous for their ability to conduct protons and exchange cations. Nafion is composed of hydrophobic main chains and pendant hydrophilic side chains. The side chains are especially important. When Nafion is introduced to a [..]

Photocatalysts - Metal Laminations Improve Performance

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 [..]

Uveal Melanoma – New Promising Treatment

The ability to monitor progression of retinal vascular diseases like diabetic retinopathy in small animal models is often complicated by their failure to develop the end-stage complications which characterize the human phenotypes in disease. Interestingly, as micro-vascular dysfunction typically precedes the onset of retinal vascular and even some neurodegenerative diseases, the ability to visualize and [..]

Holographic Display With Vision Correction

The three-dimensional (3D) vectorial nature of electromagnetic waves of light has not only played a fundamental role in science but also driven disruptive applications in optical display, microscopy, and manipulation. However, conventional optical holography can address only the amplitude and phase information of an optical beam, leaving the 3D vectorial feature of light completely inaccessible. [..]

IR Detector - Dual-Band, CMOS-Compatible, Bias-Tunable

Will automated infection tracking become standard procedure in airports around the world? Real-time thermal monitoring combined with biometric data that could be immediately extracted and analyzed (using computer vision technology) would help airport personnel quickly identify individuals with potential illness in even the most crowded terminals. Possible points of contact with the individual could also [..]

Optical Transistors

Leading research groups in the field of nanophotonics are working toward developing optical transistors – key components for future optical computers. These photonic devices will process information with photons instead of electrons, thus reducing the heat and increasing the operation speed. However, photons do not interact with each other well, which creates a big problem [..]

Interferometer Sensor

Researchers are now developing a laser-based interferometer sensor that detects coronavirus at the earliest point of infection from a saliva or nasal swab in minutes. The scientists are developing a new rapid, noninvasive optical biosensor demonstrator that will detect COVID-19 in humans as soon as it is present in the body. With the ability to [..]

Diamond Raman Laser

Lasers that emit light at the sodium line (actually a doublet) at a wavelength of about 589 nm are used to produce artificial “guide stars” in the mesosphere at an altitude of around 90 km for use with adaptive optical (AO) systems integrated with large ground-based astronomical telescopes. These artificial stars allow astronomers to use [..]

Lung Tumors

People who are at high risk of developing lung cancer, such as heavy smokers, are routinely screened with computed tomography (CT), which can detect tumors in the lungs. However, this test has an extremely high rate of false positives, as it also picks up benign nodules in the lungs. Researchers have now developed a new [..]

Mid-Infrared Lasers

For the first time, researchers have fabricated high-performance mid-infrared laser diodes directly on microelectronics-compatible silicon substrates. The new lasers could enable the widespread development of low-cost sensors for real-time, accurate environmental sensing for applications such as air pollution monitoring, food safety analysis, and detecting leaks in pipes. Most optical chemical sensors are based on the [..]
