The dynamic atmospheric and aeolian environment of Jezero crater, Mars
(American Association for the Advancement of Science, 2022-05)
Despite the importance of sand and dust to Mars geomorphology, weather, and exploration, the processes that move sand and that raise dust to maintain Mars' ubiquitous dust haze and to produce dust storms have not been well ...
Mars 2020 Perseverance Rover Studies of the Martian Atmosphere Over Jezero From Pressure Measurements
(American Geophysical Union, 2023-01)
The pressure sensors on Mars rover Perseverance measure the pressure field in the Jezero crater on regular hourly basis starting in sol 15 after landing. The present study extends up to sol 460 encompassing the range of ...
Near Surface Atmospheric Temperatures at Jezero From Mars 2020 MEDA Measurements
(American Geophysical Union, 2023-03)
The Mars Environmental Dynamics Analyzer instrument on Mars 2020 has five Atmospheric Temperature Sensors at two altitudes (0.84 and 1.45 m) plus a Thermal InfraRed Sensor that measures temperatures on the surface and at ...
Dust Lifting Through Surface Albedo Changes at Jezero Crater, Mars
(American Geophysical Union, 2023-04)
We identify temporal variations in surface albedo at Jezero crater using first-of-their-kind high-cadence in-situ measurements of reflected shortwave radiation during the first 350 sols of the Mars 2020 mission. Simultaneous ...
Crystallization Process and Site-Selective Excitation of Nd3+ in LaF3/NaLaF4 Sol–Gel-Synthesized Transparent Glass-Ceramics
(MDPI, 2021-04-22)
In this study, transparent oxyfluoride glass-ceramics (GCs) with NaLaF4 nanocrystals (NCs) were prepared by the sol–gel method for the first time. Three different molar ratios of La(CH3COO)3/Na(CH3COO) were used to obtain ...
KLaF4:Nd3+ doped transparent glass-ceramics processed by spark plasma sintering
(Elsevier, 2022-02-15)
[EN] Transparent oxyfluoride glass-ceramics (GCs) containing KLaF4 nanocrystals (NCs) doped with Nd3+ were prepared by Spark Plasma Sintering (SPS). Glass powder pellets were sintered under a vacuum atmosphere, optimizing ...
Spark plasma sintering and optical properties of Tm3+ and Tm3+ /Yb3+ doped NaLaF4 transparent glass-ceramics
(Elsevier, 2023-07)
Tm3+ doped oxyfluoride glass-ceramics (GCs) containing NaLaF4 nanocrystals (NCs) have been obtained by spark plasma sintering (SPS). First, the precursor glasses were melted and then milled and sieved to a suitable particle ...
Determination of Magnetic Structures in Magnetic Microwires with Longitudinally Distributed Magnetic Anisotropy
(MDPI, 2023-03-13)
We studied the magnetic properties of a glass-covered amorphous microwire that was stress-annealed at temperatures distributed along the microwire length. The Sixtus-Tonks, Kerr effect microscopy and magnetic impedance ...
Magnetic Characterization in the Rayleigh Region of Nanocrystalline Magnetic Cores
(MDPI, 2018-11-14)
We report on the structural and magnetic characterization of two nanocrystalline Finemet-type magnetic cores. The nanocrystalline structure developed after annealing the amorphous precursor alloy at 550 degrees C for 30 ...
Electronic Surveillance and Security Applications of Magnetic Microwires
(MDPI, 2021-04-30)
Applications in security and electronic surveillance require a combination of excellent magnetic softness with good mechanical and anticorrosive properties and low dimensionality. We overviewed the feasibility of using ...
