Ultralight Ultrafast Enzymes**
Angewandte Chemie, 2023 Abstract Inorganic materials depleted of heavy stable isotopes are known to deviate strongly in some physicochemical properties from their isotopically natural counterparts. Here we explored for the first time the effect of simultaneous depletion of the heavy carbon, hydrogen, oxygen and nitrogen isotopes on the ...

Ultrafast Science to Capture Ultrafast Motions
Ultrafast Science, 2021 We are living in a dynamic world, where all matter is in a vibrant process, whether it is a giant celestial body or a small atom. Being able to observe, analyze, and manipulate these dynamic processes is undoubtedly essential for scientific discoveries and technical innovations.

Journal of Electronic Imaging, 2022 This article introduces the fastest line detector so far published in the literature. This algorithm is 14.88 times faster than the next fastest line detector, the EDLines, and 94.7 times faster than the line segment detector. It is hundreds of times faster and more reliable than the Standard Hough Transform.

Numerical method for nonlinear optical spectroscopies: Ultrafast ultrafast spectroscopy [PDF]
The Journal of Chemical Physics, 2019 We outline a novel numerical method, called Ultrafast Ultrafast (UF2) spectroscopy, for calculating the nth-order wavepackets required for calculating n-wave mixing signals. The method is simple to implement, and we demonstrate that it is computationally more efficient than other methods in a wide range of use cases. The resulting spectra are identical

Ultrafast terahertz magnetometry [PDF]
Nature Communications, 2020 AbstractA material’s magnetic state and its dynamics are of great fundamental research interest and are also at the core of a wide plethora of modern technologies. However, reliable access to magnetization dynamics in materials and devices on the technologically relevant ultrafast timescale, and under realistic device-operation conditions, remains a ...

The Rise of Ultrafast Waves [PDF]
Developmental Cell, 2018 Traditionally, biochemical traveling waves are thought to propagate due to a coupling of bistable reactions with diffusion. Recent work proposes mechanisms by which cells achieve fast signaling without necessarily resorting to pure bistability or diffusion-mediated coupling.

A difference detection system for high precision measurements of ultrafast transmission changes [PDF]
, 1985 Ultrafast transmission changes can be recorded with high precision by means of a difference detection system. Using single pulses of low energy (0.1 nJ) and low repetition rate, variations of the transmitted energy induced by an excitation pulse are ...

CAVITY-ENHANCED ULTRAFAST SPECTROSCOPY: ULTRAFAST MEETS ULTRASENSITIVE
Proceedings of the 71st International Symposium on Molecular Spectroscopy, 2016 Ultrafast optical spectroscopy methods, such as transient absorption spectroscopy and 2D spectroscopy, are widely used across many disciplines. However, these techniques are typically restricted to optically thick samples, such as solids and liquid solutions.
