Polyphenol-peptide interactions in mitigation of Alzheimer’s disease : role of biosurface-induced aggregation
(IOS Press, 2021-05-08)
Alzheimer’s disease (AD) is the most common age-related neurodegenerative disorder,
responsible for nearly two-thirds of all dementia cases. In this review, we report the potential AD
treatment strategies focusing on ...
Spectrum simulation of rough and nanostructured targets from their 2D and 3D image by Monte Carlo methods
(2015-09)
Corteo is a program that implements Monte Carlo (MC) method to simulate ion beam analysis (IBA) spectra of several techniques by following the ions trajectory until a sufficiently large fraction of them reach the detector ...
Etude des instabilités d'interface du procédé de coextrusion
(Ecole des Mines de Paris, 1994-06-01)
Une étude expérimentale et numérique du procédé de coextrusion est abordée dans ce mémoire. On trouve essentiellement les étapes de la conception d'une filière de coextrusion comportant un hublot permettant d'observer ...
Computer Simulation of Ion Beam Analysis: Possibilities and Limitations
(2011)
Quantitative application of ion beam analysis methods, such as Rutherford backscat- tering, elastic recoil detection analysis, and nuclear reaction analysis, requires the use of computer simulation codes. The different ...
Focussed helium ion channeling through Si nanomembranes
(2018-03-15)
Channeling of low energy (25 to 35 keV) focussed He ions transmitted through crystalline Si (001) nanomembranes (50nm) has been observed using a He ion microscope. Planar (110) and (100) channeling was detected with critical ...
In-plasma analysis of plasma–surface interactions
(American Institute of Physics, 2023)
During deposition, modification, and etching of thin films and nanomaterials in reactive plasmas, many active species can interact with the
sample simultaneously. This includes reactive neutrals formed by fragmentation ...
Mitigating Alzheimer’s disease with natural polyphenols: a review
(Bentham Science, 2019-03-14)
According to Alzheimer’s Disease International (ADI), nearly 50 million people worldwide were living with dementia in 2017, and this number is expected to triple by 2050. Despite years of research in this field, the root ...
A Coupled 2 × 2D Babcock–Leighton Solar Dynamo Model. I. Surface Magnetic Flux Evolution
(2015-09)
The need for reliable predictions of the solar activity cycle motivates the development of dynamo models incorporating a representation of surface processes sufficiently detailed to allow assimilation of magnetographic ...
Critical process temperatures for resistive InGaAsP/InP heterostructures heavily implanted by Fe or Ga ions
(Elsevier, 2015-07-30)
We report on critical ion implantation and rapid thermal annealing (RTA) process temperatures that produce resistive Fe- or Ga-implanted InGaAsP/InP heterostructures. Two InGaAsP/InP heterostructure compositions, with band ...
Hydrogen analysis depth calibration by CORTEO Monte-Carlo simulation
(Elsevier, 2015-10-21)
Hydrogen imaging with sub-μm lateral resolution and sub-ppm sensitivity has become possible with coincident proton–proton (pp) scattering analysis (Reichart et al., 2004). Depth information is evaluated from the energy sum ...
