Despite the widely recognized importance of noncovalent interactions involving aromatic rings in many fields, our understanding underlying forces and structural patterns, especially impact heteroaromaticity, is still incomplete. Here, we investigate relaxation processes that follow inner-valence ionization a range molecular dimers various combinations benzene, pyridine, pyrimidine, which initiate an ultrafast intermolecular Coulombic decay process. Multiparticle coincidence momentum...
The acoustic posterior shadowing effects of bubbles influence the accuracy for defining location and range ablated thermal lesions during focused ultrasound surgery when using ultrasonic monitoring imaging. This paper explored feasibility Nakagami distribution to evaluate region induced by exposures at different power levels in transparent tissue-mimicking phantoms. mean value parameter m was about 0.5 cavitation increased around 1 region. images were not subject significant bubbles....
Abstract Intense particle beams generated from the interaction of ultrahigh intensity lasers with sample foils provide options in radiography, high-yield neutron sources, high-energy-density-matter generation, and ion fast ignition. An accurate understanding beam transportation behavior dense matter is crucial for all these applications. Here we report experimental evidence on one order magnitude enhancement intense laser-accelerated proton stopping ionized matter, comparison current-widely...
Elemental identification of individual microsized aerosol particles is an important topic in air pollution studies. However, simultaneous and quantitative analysis multiple constituents a single particle with the noncontact situ manner still challenging task. In this work, we explore laser trapping-LIBS-machine learning to analyze four elements (Zn, Ni, Cu, Cr) absorbed micro-carbon black air. By employing hollow beam for trapping, can be restricted range as small ∼1.72 μm, which much...
We report experimental studies of electron-impact ionization nitrogen (${\mathrm{N}}_{2}$) and oxygen (${\mathrm{O}}_{2}$) molecules using a cold target recoil ion momentum spectrometer (COLTRIMS, reaction microscope). The is detected in coincidence with one outgoing electron such that the vectors consequently kinetic energies for these final-state particles are determined. cross sections producing doubly singly charged parent ions were measured as function incident energy ranging from 50 to...
We have measured and calculated fully differential cross sections for target ionization in 16-MeV O${}^{7+}$+He 24-MeV O${}^{8+}$+Li collisions. As previous studies, the case of He we observe a pronounced forward shift angular distribution electrons relative to direction momentum transfer q at small $q$ ($q$ 1 a.u.). An unexpected result is that also find strong large > 2 a.u.), while intermediate this becomes very weak or even turns into backward shift. For Li target, contrast,...
Conventional range hoods cannot effectively prevent the oil fumes containing cooking-induced harmful material from escaping into kitchen Air curtains and guide plates have been used in to reduce escape of airborne emissions heat, thereby improving environment cook's degree comfort. In this article, numerical simulations are study effects jet velocity an air curtain, angle width slot, area plate, exhaust rate hood on perceived temperature, concentration fumes, release temperature escaped a...
Abstract In this work, we review current trends in China to investigate beam plasma interaction phenomena. Recent progresses on low energy heavy ions and interaction, ion beam-plasma interactions under the influences of magnetic fields, high radiography through marginal range method, deposition highly charged surfaces Raman spectroscopy after irradiation are presented.
The rapid development of 5G network technology has gained much popularity as well concerns about its adverse effects. In this study, we investigated the effects 4.9 GHz (one working frequencies communication) radiofrequency (RF) field on emotional behaviours and spatial memory in adult male mice. Open test (OFT), tail suspension (TST) Y maze were used to evaluate anxiety, depression-like behaviour ability, respectively. It was found that anxiety-like ability mice did not change, but induced...
In this paper, silicone rubber (SR) and ethylene propylene-diene monomer (EPDM) used in 110 kV prefabricated joints of XLPE cables were chosen as subjects, a multi-stress experimental device was set up to simulate the insulation interface. Different mechanical tensions and/or AC electrical stresses applied samples at interface composed SR/EPDM. After preset times, microscopic observations, together with measurements properties, volume resistivity, crosslinking degree, attenuated total...

Kinematically complete experiments were performed on the ionization of a laser-cooled lithium target from different initial states, Li(2s), Li(2p) and Li(1s), by 6 MeV H+ 1.5 amu−1 O8 + impact. In measured doubly differential cross sections as function electron energy transverse momentum transfer, significant state dependence is found. Furthermore, comparison to quantum mechanical theory shows surprising discrepancies for Li(2s) Li(1s) while there good agreement state.
