Hydrogen is a key component in the search for sustainable and pure energy. But because the gas is explosive when combined with air, this shift faces significant difficulties. It is essential to be able to identify hydrogen leaks as soon as feasible because of this. Researchers have created an optical sensor that can identify hydrogen [..]

Creating new information and communication technologies presents new challenges for scientists and businesses. The most promising approach to overcoming these difficulties is to create novel quantum materials with exceptional properties derived from quantum physics. A multinational team has created a material in which the curvature of the space fabric in which electrons evolve can be [..]

Worldwide, sudden cardiac arrest (SCA) is one of the main causes of death. The SCA-to-resuscitation interval highlights the therapeutic need for accurate and prompt SCA detection, a critical factor in determining patient outcomes. This application may benefit from the non-invasive visual method called near-infrared spectroscopy (NIRS). A non-invasive optical biosensing method called near-infrared spectroscopy (NIRS) [..]

Researchers have created new imaging technology that can generate 3D maps in real-time and across the full surface of the uterus during labor, revealing the magnitude and distribution of uterine contractions. This technology, which builds on imaging techniques long used to image the heart, can image uterine contractions noninvasively and in much more detail than [..]

Diagnostic imaging significantly improves clinical analysis and medical intervention by providing doctors and scientists with essential visual representations of internal body structures. Researchers are constantly making strides in knowing how different imaging technologies can improve human health. Brillouin microscopy, in contrast to more traditional imaging techniques like confocal fluorescence microscopy, can obtain mechanical data (such [..]

A research team used a microresonator’s two optical and two mechanical modes to show nonreciprocal routing between modes with different frequencies through radiation pressure force. Systems for processing information and performing detection based on photons and phonons often include optical and acoustic nonreciprocal devices. Although magnetically induced nonreciprocity is frequently used in optical devices, device [..]

Researchers’ simulations of ice-cold electron beams may open the door to shrinking X-ray free-electron lasers (X-FELs) to a small portion of their present dimensions. X-FELs, also known as “engines of discovery,” transform the kinetic energy of an electron beam into strong photon bursts that extend down to hard X-ray wavelengths. For hot-dense matter research, resolving [..]

Researchers discovered that one application of half-dose photodynamic therapy (PDT) targeting the fovea helped treat patients with chronic central serous chorioretinopathy (CSC) structurally and functionally, and they did not experience foveal atrophy. To ascertain the impact of this therapeutic approach, the study team conducted a retrospective analysis of data from patients with chronic CSC who [..]

Although uses for low-light imaging are numerous, they are only available in the visible spectrum, where detector noise performance is optimal. Although the camera’s noise floor is about 200 times higher, researchers demonstrated a full-field, homodyne imaging device that can image at the single-photon level in the shortwave infrared. Gabor first proposed this interference method [..]

Astronomers are aware that a larger telescope has more potent imaging capabilities. The first ultrathin, compact metalens telescope capable of imaging distant objects, such as the moon, was developed by a research team to maintain the power while streamlining one of the bulkier components. Traditional camera or telescope lenses are heavy and bulky because they [..]

With the arrival of the Metaverse era, there has been an increase in expectations that virtual reality (VR) and augmented reality (AR) technologies will improve everyday convenience and industry productivity performance. A joint research team has introduced core technology for smart contact lenses to implement AR-based navigation through 3D printing. According to the research team, [..]

Researchers have combined 3D flash and beam-scanning laser light sources to create a 3D, nonmechanical system. According to the researchers, the system can measure the distance of poorly reflective objects in the field of view (FOV) and automatically track their motion — a capability not found in conventional lidar that will allow autonomous vehicles to [..]

Most mainstream commercial solutions for 3D display are based on binocular vision principles to achieve more realistic visual experiences. However, unlike when viewing real 3D objects, the viewer’s depth of visual focus remains constant while wearing the device to obtain 3D information. This vergence accommodation conflict predisposes the viewer to visual fatigue and vertigo, limiting [..]

The C-reactive protein (CRP) is an acute-phase protein that plays a role in inflammation. Furthermore, CRP is a biomarker used in blood analyzer diagnostics to predict the risk of cardiovascular disease (CVD) and monitor bacterial and viral infections. Venipuncture is still required to measure plasma CRP and must be performed by trained phlebotomists. As a [..]

Scientists have created an ultrafast photoacoustic imaging system that detects molecular changes in major brain function disorders. While positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) produce adequate images, they suffer from low spatial resolution, which makes distinguishing between adjacent bodily structures difficult, and low temporal resolution, which is the time it takes [..]

Patients with bone fractures and defects face serious health risks. Synthetic scaffolds have been actively investigated for clinical therapeutics to promote critical-sized bone regeneration, and electrical stimulations are recognized as an effective auxiliary to facilitate the process. Researchers created a three-dimensional (3D) biomimetic scaffold with thin-film silicon (Si) microstructures. This Si-based hybrid scaffold provides a [..]

Researchers have made a significant breakthrough in thermal radiation by discovering a new method for producing spinning thermal radiation in a controlled and efficient manner using artificially structured surfaces known as metasurfaces. Thermal radiation, caused by random fluctuations in materials, has traditionally been regarded as an incoherent signal. The emitted heat from most conventional thermal [..]
