Max Born Institute demonstrates attosecond spectroscopy at 1 kHz 06 Mar 2024 New pump-probe method promises new investigation of fast electron dynamics. https://lnkd.in/eceHW-fw

The advent of train or isolated attosecond pulses have paved the interest into studying, manipulating and controlling electronic wave packets through Ramsey interference. Current methods for producing an isolated attosecond pulses always introduce an intrinsic chirp (time-dependent on the carrier frequency of the laser pulse) where this chirp decreases the isolated attosecond pulse intensity and broadens its duration while keeping its bandwidth constant. In this work, to understand the effect of the intrinsic chirp on the photoelectron momentum distribution (PMD), we examine the linear process of single photon single ionization of an S-state atom using a pair of oppositely circularly polarized laser pulses with a focus on the chirp nature of the pulse electromagnetic radiations while they are temporally separated eventually. The result of this work leads to an understanding and thus control of electron spirals produced in the PMD using chirped attosecond pulses. Check out our work below:

#Refractorymaterialtestingmachine #Xrayfluorescencespectrometerworkingvideo Feature: HNJC-XT1 X-ray fluorescence spectrometer adopts energy dispersive X-ray fluorescence technology. Its principle is to emit X-rays through an X-ray tube to irradiate the sample, measure and analyze the X-ray fluorescence generated by the sample, and then know the elemental composition of the sample and obtain qualitative and quantitative information in the substance.

💡Did you know... The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis. The electron flow starts at complexes 1, 2, 3 and 4 then makes ATP once it reaches complex 5 (known as ATP synthase). The electron flow is limited or completely blocked if there is a “kink” in the hose. Erchonia lasers are able to target each of those complexes with our red, violet, and green laser technology to unkink the hose.

Active particles immersed in a fluid medium at the microscale, also known as microswimmers, are ubiquitous in both nature (e.g. cells, bacteria) as well as in artificial systems (e.g. micro-robots). Microswimmers routinely experience flowing fluids in confined environments such as pathogens moving through blood vessels or microrobots programmed for targeted drug delivery applications. In these situations, the interaction between fluid flow and particle motility can result in rich dynamics. In our work (with Brendan Harding and Yvonne Stokes), we investigated the motion of a simple active particle suspended in fluid flow through a straight channel. We observe a diverse set of active particle trajectories, both regular and chaotic, which we classify into different types of swinging, trapping, tumbling and wandering motion. Outcomes of this work may have implications for dynamics of natural and artificial microswimmers in confined regions. In below animation, left panels show the side view of the 3D channel, middle panels show the cross-sectional view, and right panels show the particle orientation.
