Observation of electron emission in the nuclear reaction between protons and deuterons

Physics Letters B, 2017
Proton–deuteron fusion reaction has been studied using a proton beam with an energy of 260 keV and a deuterium-implanted graphite target. The reaction product, 3He, usually de-excites by γ-ray emission.

Whispering gallery and surface mode of electrons in lateral and corrugated quantum dots

Materials Research Express, 2020
Quantum dots (QDs) are fundamental elements in the applications related to light–matter interaction, such as solar cells, lasers and sensors. Moreover, some modes of electrons including whispering galley modes (WGMs) and surface modes can be incorporated

Intense laser interaction with micro-bars

Scientific Reports, 2023
Intense laser fields interact very differently with micrometric rough surfaces than with flat objects. The interaction features high laser energy absorption and increased emission of MeV electrons, ions, and of hard x-rays.

Very High-Energy Electron Therapy Toward Clinical Implementation

Cancers
The use of very high energy electron (VHEE) beams, with energies between 50 and 400 MeV, has drawn considerable interest in radiotherapy due to their deep tissue penetration, sharp beam edges, and low sensitivity to tissue density. VHEE beams can be precisely steered with magnetic components, positioning VHEE therapy as a cost-effective option between ...

Very High Energy Electrons (50 – 250 MeV) and Radiation Therapy

Technology in Cancer Research & Treatment, 2002
High energy electron beams in the range 150–250 MeV are investigated to evaluate their feasibility for radiotherapy. Monte Carlo simulation results from PENELOPE code are used to determine lateral spread and penetration of these beams. It is shown that dose distribution of electron beams compare favorably with photon beams.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
