Theoretical physicists have devised a mathematical model of two different molecules reacting within so called nanoreactors that act as catalysts. They gained surprising new insights as to what factors promote reactions and how to control and select them. The model is relevant for a wide range of research fields, from biophysics to energy materials.
Environmental scientists led by the Virginia Tech College of Science have discovered that the burning of coal produces incredibly small particles of a highly unusual form of titanium oxide.

Scientists have devised a new technique that uses quantum entanglement of a million rubidium atoms to detect weak radio waves as accurately as the most sensitive radio frequency magnetometers available.
The new RA-532H Surface Reflectance Analyzer from Canon USA, Inc. Optoelectronic Components is capable of surface measurements at three different angles (20°, 60°, and 85°). Utilized measurement methods include standard compliant gloss, haze, Image Clarity (IC), and 1-D and 2-D BRDF (Bidirectional Reflectance Distribution Function) measurements. The analyzer can be used for a variety of evaluation and inspection applications with many types of surfaces such as film, paper, and automotive, printed, or painted surfaces.
The RV1100 is a 3D machine vision system designed to measure and recognize randomly assembled production line parts with complex shapes and very few distinguishing features for robotic arm systems. It offers the benefits of one-time measurements of 3D pose, high-speed recognition, improved productivity, and reduced production costs. The RV1100 is ideal for use in industrial production applications such as automobile parts manufacturing, car manufacturing, and electronics manufacturing.
Piezo nanopositioning stages offer high-resolution and scanning speed, making them useful for super-resolution microscopy and optical trapping. The P-563 PIMars XYZ-Stages are designed with a parallel-kinematics arrangement with higher precision and responsiveness compared to nested or stacked multi-axis positioners.
Telops offers a variety of high-performance scientific instruments to meet the most demanding research applications. The MS-IR Series of time-resolved, multispectral imagers are able to combine measurements obtained with various attenuation filters to achieve a composite HDR image that shows hot and cold objects at the same time.
Flexible endoscopes are used in medical procedures where the scope cannot bend. This animation from SCHOTT demonstrates the transmission of light and data through external and internal rigid fiber optic light cables in endoscopy.
One of the key parameters for understanding how a laser will perform in an application is the spatial intensity distribution. In many industial laser cutting or welding applications, monitoring the beam quality is critical for successful operation. The measurement of the beam can either be made during the design stage of the laser, or it might be more sufficient for continuous real-time monitoring during the laser’s operation. This white paper addresses the general need for laser beam profile analysis, describes laser beam analysis instruments, and provides an overview of laser applications, in particular for infrared wavelengths.

There are many challenges associated with recording lightning with high-speed video images, including placing the camera close enough to the chosen structure in an observable way, as well as the filming process requiring a long observation time to capture the strike – if it happens at all. Now, for the first time, a team of researchers has captured lightning striking a rod using Vision Research’s high-speed cameras. The results not only broaden the understanding of how lightning connects with lightning rods, but also provide the field data necessary to improve current lightning protection systems.
An interferometer is a common instrument for measuring optical surfaces to very high precision that can be applied with care to enable extremely low uncertainty measurements to address tight metrology requirements. The ability of an interferometer to quantify mid-spatial frequency content is defined not only by its sampling density (camera resolution), but also by the many critical design aspects of the optical illumination and imaging system. The instrument transfer function (ITF) quantitatively characterizes the response of the instrument as a function of spatial frequency.
Hyperspectral imaging is a valuable technique for revealing data the eye alone cannot capture. Now, a new class of hyperspectral imaging systems is taking things one step further by addressing image quality issues and enabling further ease-of-use.
The two types of sensing include local measurement points and distributed sensing. This paper presents the technical basics behind sensing over fiber technologies, its main applications, and the cabling solutions involved.
