Transparent Surfactant‐Based Isotropic Systems for Topical Co‐Delivery of Hydrophilic and Lipophilic Actives for Striae Distensae

open access: yesJournal of Surfactants and Detergents, EarlyView.
ABSTRACT Striae distensae are common dermal lesions that negatively affect skin appearance, and topical management remains limited by challenges related to skin deposition and residence time. Here, we developed transparent surfactant‐based isotropic systems for the topical co‐delivery of ascorbic acid (AA), retinoic acid (RA), and lavender essential ...

Melting and defect transitions in FeO up to pressures of Earth’s core-mantle boundary

open access: yesNature Communications, 2023
The high-pressure melting curve of FeO controls key aspects of Earth’s deep interior and the evolution of rocky planets more broadly. However, existing melting studies on wüstite were conducted across a limited pressure range and exhibit substantial ...

The role of rheology in lithospheric thinning by mantle plumes [PDF]

open access: yesGeophysical Research Letters, 1999
Lithospheric thinning by mantle plumes is an important planetary heat transfer process resulting in the broad topographic uplift that characterizes the volcanic rises on Venus, the Tharsis rise on Mars, and several hotspot swells on Earth. We present a suite of time‐dependent, three‐dimensional numerical calculations of a plume impinging upon the ...

Melting temperatures of MgO under high pressure by micro-texture analysis

open access: yesNature Communications, 2017
Melting behaviour of MgO under pressure remains unclear despite the importance of constraining the rheology and composition of the Earth’s mantle. Here, the authors show that melting temperatures in earlier static experiments were underestimated based on

Deformation of Polycrystalline MgO Up to 8.3 GPa and 1270 K: Microstructures, Dominant Slip-Systems, and Transition to Grain Boundary Sliding

open access: yesFrontiers in Earth Science, 2022
Ferropericlase is the second most abundant mineral in the Earth’s lower mantle and its mechanical properties have a strong influence on the rheology of this region.

Robust β‐myrcene block copolymer elastomeric vitrimers

open access: yesPolymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Dislocation creep may control bridgmanite deformation in the Earth’s lower mantle

open access: yesCommunications Earth & Environment
Seismic anisotropy in the Earth’s lower mantle, particularly around subduction zones, is commonly attributed to deformation by dislocation creep, yet much of the lower mantle appears nearly isotropic.

Gas check prevention during calendering of poly(vinyl chloride) films using poly(caprolactone)‐based additives

open access: yesJournal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 441-452, March 2025.
Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and

Viscoelastic relaxation of the upper mantle and afterslip following the 2014 MW8.1 Iquique earthquake

open access: yesEarthquake Research Advances, 2021
An improved understanding of postseismic crustal deformation following large subduction earthquakes may help to better understand the rheological properties of upper mantle and the slip behavior of subduction interface.
