A kinetic Monte Carlo study of the C3S dissolution mechanism
(Elsevier, 2024-06-09)
Understanding the mechanism that controls cement hydration and its stages is a long-standing challenge. Over a decade ago, the mineral dissolution theory was adopted from geochemistry to explain the hydration rate evolution ...
Elucidating the synergistic effects of temperature rise inhibitor at the water tricalcium silicate interface
(ACS, 2024-04)
Organic–inorganic composites play a crucial role in modulating concrete properties, encompassing interfacial interactions and their synergistic mechanisms. Unraveling these interactions presents a formidable challenge. In ...
CO and O2 interaction with kinked Pt surfaces
(ACS, 2024-04)
We investigate the chemical interaction of carbon monoxide (CO) and oxygen (O2) with kink atoms on steps of platinum crystal surfaces using a specially designed Pt curved sample. We aim at describing the fundamental stages ...
Fluorometric measurement of calmodulin-dependent peptide–protein interactions using dansylated calmodulin
(Bio-protocol LLC, 2024-04)
The assessment of peptide–protein interactions is a pivotal aspect of studying the functionality and mechanisms of various bioactive peptides. In this context, it is essential to employ methods that meet specific criteria, ...
Optical fiber interferometer for temperature-independent refractive index measuring over a broad range
(Elsevier, 2021-07)
The present work relates to manufacturing of a simple interferometric optical fiber refractometer that features broad refractive index measuring range without ambiguity. The device consists of a cylindrical polymer cavity ...
Jupiter's third largest and longest-lived oval: Color changes and dynamics
(Elsevier, 2021-06)
The transition region between the North Equatorial Band (NEBn) and North Tropical Zone (NTrZ) in Jupiter is home to convective storms, systems of cyclones and anticyclones and atmospheric waves. Zonal winds are weak but ...
Venus cloud discontinuity in 2022: The first long-term study with uninterrupted observations
(EDP Sciences, 2023-04)
Context. First identified in 2016 by the Japan Aerospace eXploration Agency (JAXA) Akatsuki mission, the discontinuity or disruption is a recurrent wave observed to propagate over decades at the deeper clouds of Venus ...
Multilayer hazes over Saturn’s hexagon from Cassini ISS limb images
(Nature, 2020-05-08)
In June 2015, Cassini high-resolution images of Saturn's limb southwards of the planet's hexagonal wave revealed a system of at least six stacked haze layers above the upper cloud deck. Here, we characterize those haze ...
Cellular patterns and dry convection in textured dust storms at the edge of Mars North Polar Cap
(Elsevier, 2022-11)
We present a study of textured local dust storms that develop at the northern polar cap boundary on Mars springtime. We have used images obtained with VMC and HRSC cameras onboard Mars Express and MARCI on MRO to analyze ...
Characterisation of deposited dust particles on Mars insight lander Instrument Context Camera (ICC) lens
(Elsevier, 2023-03)
The ubiquitous dust in the Martian environment plays a key role in its weather and climate: it must be taken into account in the interpretation of remote sensing data and observations, and could pose a potential risk to ...
