Fate of Hydrous Fe‐Rich Silicate Melt in Earth's Deep Mantle
Geophysical Research Letters, 2019 Density of silicate melt dictates melt migration and establishes the gross structure of Earth's interior. However, due to technical challenges, the melt density of relevant compositions is poorly known at deep mantle conditions.

A General Workflow for Tangential Flow Filtration Perfusion Scale‐Up
Biotechnology and Bioengineering, EarlyView.ABSTRACT Tangential flow filtration (TFF) perfusion using hollow‐fiber modules offers substantial advantages over other mammalian cell retention technologies. Recently, increased awareness of Starling flow has helped to enhance filtration performance to similar, or even higher levels compared to alternative technologies.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Seismology of the lower mantle and core‐mantle boundary [PDF]
Reviews of Geophysics, 1995 The thermal and chemical processes operating near the core‐mantle boundary (CMB) play a major role in the planet's evolution, influencing the magnetic field behavior, chemical cycling in the mantle, irregularities in the rotation and gravitation of the planet, and the configuration of mantle convection.

Chemistry – A European Journal, EarlyView.The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Does Heterogeneous Strain Act as a Control on Seismic Anisotropy in Earth’s Lower Mantle?
Frontiers in Earth Science, 2020 Plastic deformation and texture development in minerals of the lower mantle can result in seismic anisotropy, and studying deformation of lower mantle materials is therefore important for interpreting lower mantle flow.

Influencing Parameters at Drum Screens for Packaging Screening
Chemie Ingenieur Technik, EarlyView.Drum (trommel) screens are extensively utilized in the classification of packaging waste according to its particle size. The present study aims to quantify the size‐classification behaviour of elongated, hollow packaging‐like items (representing bottles, tubes and cups) using cylindrical and tubular test pieces.

Fe2+ Partitioning in Al‐Free Pyrolite: Consequences for Seismic Velocities and Heterogeneities
Geophysical Research LettersIron partitioning among the main lower mantle phases, bridgmanite (Bm) and ferropericlase (Fp), has non‐monotonic behavior owing to the high‐spin to low‐spin crossover in ferrous iron (Fe2+) in Fp.
