Matrix-Free Assisted Laser Desorption Ionization Using Metal-Organic Frameworks

Matrix-assisted laser desorption/ionization (MALDI) is a soft ionization technique that is widely applied in the characterization of large biomolecules using various mass spectrometry (MS) analyzers, specifically, time-of-flight (TOF) analyzers. The MALDI process involves the deposition of an analyte solution onto a metal substrate before the addition of a matrix. The matrix/analyte dry spot is exposed to a UV laser, and the laser energy that is absorbed by the matrix/analyte is converted into heat energy that initiates charge transfer, which results in the desorption of the matrix and analyte molecules in ionized form. The positive ions are then accelerated through a vacuum into MS analyses.

Fiber Optic Rotary Joints Add a Spin to Sensing, Mobile, and Robotic Fiber Systems

To the passing optical signals, fiberoptic rotary joints (FORJs) are nothing more than fiber connectors, which provide connection between one or multiple fibers. Their unrestricted ability to rotate, however, gives them a critical role in many sensing, mobile, and robotic fiber systems such as ROVs (remotely operated vehicles), aerostat radars, submarines, satellite antennae, OCT (optical coherence tomography), mining vehicles, cranes, wind turbines, robotic vehicles, broadcasting (mobile cameras), etc. This article discusses some of the applications where optical rotary joints are indispensable.

Hydraulic Propulsion an Alternative to Drone Batteries

Drones require heavy batteries or lots of electrical components, which leaves little room for the actual payload. A Purdue University team came up with a method to use fluid power technology for autonomous vertical takeoff and landing (VTOL) vehicles.

US and Japanese Scientists Conduct Joint Composites Study

Dr. Keisuke Umezawa of the Air Systems Research Center in the Japanese Ministry of Defense (JMoD) recently joined the Air Force Research Laboratory on an engineers and scientists exchange program (ESEP). The JMoD chose Umezawa for the ESEP based on his experience as a stress analysist of polymer matrix composite materials. Also, Umezawa has been heavily involved in the development of the next generation Japanese fighter aircraft, including the development of the test program for prototype PMC structures.

Insect-Inspired Arm Improve Drones

Most drones are not able to withstand wind because of their fixed-arm design. But a new drone design works in windy conditions, is more energy-efficient, and can handle a larger payload. It was inspired by the wings and flight patterns of insects and incorporates automatic folding arms that can make in-flight adjustments.
