Radiation and Scattering [PDF]

open access: yes, 2017
AbstractAt this point, we have made a rather extensive investigation into the sounds that excite Helmholtz resonators as well as the departures from equilibrium that propagate as plane waves through uniform or inhomogeneous media. We have not, as yet, dealt with how those sounds are actually produced in fluids. Our experience tells us that sound can be

On p_T-broadening of high energy partons associated with the LPM effect in a finite-volume QCD medium

open access: yes, 2011
We study the contributions from radiation to $p_{\perp}$-broadening of a high energy parton traversing a QCD medium with a finite length $L$. The interaction between the parton and the medium is described by decorrelated static multiple scattering ...

Copper Doping Enhances the Activity and Selectivity of Atomically Precise Ag44 Nanoclusters for Photocatalytic CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Simulating synchrotron radiation in accelerators including diffuse and specular reflections

open access: yesPhysical Review Accelerators and Beams, 2017
An accurate calculation of the synchrotron radiation flux within the vacuum chamber of an accelerator is needed for a number of applications. These include simulations of electron cloud effects and the design of radiation masking systems.

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Scattering Blanketing Effect of Earth’s Proto-atmosphere: Enhanced Suppression of Planetary Radiation and Magma Ocean Cooling

open access: yesThe Astrophysical Journal
The thermal evolution of magma oceans formed by giant impacts is strongly influenced by a proto-atmosphere through its blanketing effect, which suppresses outgoing planetary radiation.

Radiation from monopole scattering

open access: yesPhysics Letters B, 1988
Abstract Estimates are made of the energy radiated in two processes involving slowly moving BPS monopoles - the 90° scattering of pure monopoles and the circular orbit of well-separated dyons.

Novel aspects of radiation reaction in the classical and the quantum regime

open access: yes, 2014
This work is dedicated to the study of radiation reaction signatures in the framework of classical and quantum electrodynamics. Since there has been no distinct experimental validation of radiation reaction and its underlying equations so far and its ...

Bimetallic Nanoparticles as Cocatalysts for Photocatalytic Hydrogen Production

open access: yesAdvanced Functional Materials, EarlyView.
Recent developments have introduced bimetallic nanoparticles as effective cocatalysts for photocatalytic systems. This review explores the rapidly expanding research on bimetallic cocatalysts for photocatalytic production of hydrogen, emphasizing the creation of carrier‐selective contacts, localized surface plasmon resonance effects, methodologies for ...

STUDY OF IMPACT CARBON MATTER OF THE KARA ASTROBLEME BY SMALL-ANGLE SCATTERING OF SYNCHROTRON RADIATION [PDF]

open access: yesМинералогия, 2018
The study of the metamorphosed carbonaceous matter (MCM) of the Kara astrobleme (PayKhoy, Russia) by the methods of small-angle scattering of X-ray synchrotron radiation (SAXS) and high resolution transmission electron microscopy (HRTEM) is described ...
