Compact forward-viewing multimodal fluorescent and optical coherence tomography endomicroscopic probe

International Journal of Optomechatronics
We present a compact multimodal endomicroscope that enables simultaneous fluorescence (FL) and optical coherence tomography (OCT) imaging. While current endoscopy techniques are effective for wide-area and rapid inspection, there is a growing demand for ...

Stroboscopic neutron scattering measurements using Raspberry Pi‐based sample environment event mode

Journal of Applied Crystallography, Volume 59, Issue 5, Page 1645-1654, October 2026.
An inexpensive device based on a Raspberry Pi can give neutron scattering instruments the ability to carry out stroboscopic measurements in a relatively simple and flexible fashion. Stroboscopic measurements can be used to study fast kinetic processes in condensed matter systems.An inexpensive single‐board computer (Raspberry Pi 5) was employed to ...

A New Methodology for Vibration Error Compensation of Optical Encoders

Sensors, 2012
Optical encoders are sensors based on grating interference patterns. Tolerances inherent to the manufacturing process can induce errors in the position accuracy as the measurement signals stand apart from the ideal conditions.

‘The big chunky belemnite’: a new relict megateuthidid from the Oxfordian (Late Jurassic) of Wyoming, USA, and its place in the evolutionary history of the group

Papers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract We describe and discuss two finds of large and untypical belemnite rostra originating from the upper part of the Sundance Formation (Oxfordian) of Wyoming, USA. With a diameter reaching c. 60 mm at the anterior end, these rostra are the thickest known for belemnites so far.

Catalyst‐Free Cyanation of Arenes by Acetonitrile in a Plasma–Liquid Microreactor

Chemistry – A European Journal, Volume 32, Issue 32, 24 August 2026.
An original approach of arylnitrile synthesis was developed by generating an argon plasma in contact with solutions of arene in acetonitrile within a gas‐liquid microreactor. Plasma activation of acetonitrile generated cyano radicals, enabling a catalyst‐free C‐H cyanation of arenes.
