Animal stroke models and outcome evaluation: A review

Animal Models and Experimental Medicine, EarlyView.
Rodents are the preeminent stroke model species. Large animal models exist too, but are poorly standardized. Ischemic and hemorrhagic experimental models are available, with the intraluminal filament model being predominant. Outcomes are evaluated via quantifying subjects' sensorimotor impairment, cognitive memory faculties, degree of cellular ...

MD and TEM evaluation of swift Xe ion induced latent tracks in Si3N4 [PDF]

Eurasian Journal of Physics and Functional Materials, 2019
As known silicon nitride ceramics is considered as a candidate material for inert matrix fuel hosts used for transmutation of minor actinides. Unfortunately, by now very limited data is devoted to investigate of its stability under high energy heavy ion ...

External beam for the Heavy Ion Accelerator Facility

, 2022
Radiotherapy using protons and heavier ions is emerging as an alternative to traditional photon radiotherapy for cancer treatment. Ions have a depth-dose profile that results in high energy deposition at the end of the particle's path, with a relatively ...

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Change in Superparamagnetic State Induced by Swift Heavy Ion Irradiation in Nano-Maghemite

Metals
The effect of swift heavy ion irradiation on sol–gel-prepared maghemite nanoparticles was studied by 57Fe transmission Mössbauer spectroscopy and X-ray diffractometry (XRD).

Enhancing and decoupling magnetic anisotropy and tunnel magnetoresistance in CoFe2O4/MgO bilayers via swift heavy ion irradiation [PDF]

AIP Advances
Magnetic tunnel junctions (MTJs) formed by CoFe2O4 and MgO are key components to form memory elements in magnetic random access memory (MRAM) for high-density data storage applications.

Single-ion induced surface modifications on hydrogen-covered Si(001) surfaces—significant difference between slow highly charged and swift heavy ions

New Journal of Physics, 2021
Hydrogen-covered Si(001) surfaces were exposed to swift heavy ions (SHI) and slow highly charged ions (HCI). Using scanning tunneling microscopy as analysis tool, the ion-induced modifications on the surface were resolved on the atomic scale.

Excitation and Relaxation of Swift Heavy Ion Irradiated Dielectrics

e-Journal of Surface Science and Nanotechnology, 2010
The structural modifications of insulators after swift heavy ion irradiation are studied by applying a combination of the Monte-Carlo method (MC), used to describe the excitation and relaxation induced by the penetrating ion in the electronic subsystem, with the two temperature model (TTM) describing the temporal evolution of the lattice temperature ...

Investigations on particle dynamics in a high intensity heavy ion linac for inertial fusion [PDF]

, 2005
Die Physik intensiver Ionenstrahlen wird zur Zeit für verschiedene neue Hochstrom- und Hochenergie-Beschleunigeranlagen untersucht. Ein kritischer Punkt ist dabei die Minimierung der Strahlverluste, um die Aktivierung der Beschleunigerstruktur zu ...
