Magnetosomes could be protective shields against metal stress in magnetotactic bacteria
(Nature, 2020-07)
Magnetotactic bacteria are aquatic microorganisms with the ability to biomineralise membrane-enclosed magnetic nanoparticles, called magnetosomes. These magnetosomes are arranged into a chain that behaves as a magnetic ...
Modifying the magnetic response of magnetotactic bacteria: incorporation of Gd and Tb ions into the magnetosome structure
(Royal Society of Chemistry, 2022-06)
Magnetotactic bacteria Magnetospirillum gryphiswaldense MSR-1 biosynthesise chains of cube-octahedral magnetosomes, which are 40 nm magnetite high quality (Fe3O4) nanoparticles. The magnetic properties of these crystalline ...
Magnetotactic bacteria for cancer therapy
(American Institute of Physics, 2020-08-21)
Magnetotactic bacteria (MTB) are aquatic microorganisms that are able to biomineralize membrane-enclosed magnetic nanoparticles called magnetosomes. Inside the MTB, magnetosomes are arranged in a chain that allows MTB to ...
Investigating the Size and Microstrain Influence in the Magnetic Order/Disorder State of GdCu2 Nanoparticles
(MDPI, 2020-06-05)
A series of GdCu [Math Processing Error] nanoparticles with controlled sizes ranging from 7 nm to 40 nm has been produced via high-energy inert-gas ball milling. Rietveld refinements on the X-ray diffraction measurements ...
Scalable IoT Architecture for Monitoring IEQ Conditions in Public and Private Buildings
(MDPI, 2022-03-21)
This paper presents a scalable IoT architecture based on the edge–fog–cloud paradigm for monitoring the Indoor Environmental Quality (IEQ) parameters in public buildings. Nowadays, IEQ monitoring systems are becoming ...
Calibration of the X-ray Diffraction Technique in Measuring In-service Stresses in Corrugated Steel Bars
(Springer, 2021-10-25)
[EN]The X-ray diffraction technique for determining residual stresses in construction steels has been commonly used in the international scientific community for decades. Taking advantage of the concepts on which the ...
Switchable chiral transport in charge-ordered kagome metal CsV3Sb5
(Nature, 2022-10)
When electric conductors differ from their mirror image, unusual chiral transport
coefficients appear that are forbidden in achiral metals, such as a non-linear electric
response known as electronic magnetochiral anisotropy ...
Multi-model Meteorological and Aeolian Predictions for Mars 2020 and the Jezero Crater Region
(2021)
Nine simulations are used to predict the meteorology and aeolian activity of the Mars 2020 landing site region. Predicted seasonal variations of pressure and surface and atmospheric temperature generally agree. Minimum and ...
Radiation and Dust Sensor for Mars Environmental Dynamic Analyzer Onboard M2020 Rover
(MDPI, 2022-04-10)
The Radiation and Dust Sensor is one of six sensors of the Mars Environmental Dynamics Analyzer onboard the Perseverance rover from the Mars 2020 NASA mission. Its primary goal is to characterize the airbone dust in the ...
Impact of ionic quantum fluctuations on the thermodynamic stability and superconductivity of LaBH8
(APS, 2022-10-19)
The recent prediction of a metastable high-symmetry Fm-3m phase of LaBH8 gives hopes to reach high superconducting critical temperatures at affordable pressures among ternary hydrogen-rich compounds. Making use of ...
