The Effects of Dehydration Temperature and Monomer Chirality on Primitive Polyester Synthesis and Microdroplet Assembly

Macromolecular Chemistry and Physics, Volume 223, Issue 23, December 2022., 2022
Polyesters synthesized prebiotically through dehydration synthesis of α‐hydroxy acids can assembly into membraneless microdroplets proposed to be primitive compartment models. Here, in order to more widely probe the conditions amenable to such primitive polyester microdroplet formation, the effects of synthesis temperature and monomer chirality on ...

Cost‐effective in‐mine seismic experiments to image platinum deposits and associated geological structures at Maseve platinum mine, South Africa

Near Surface Geophysics, Volume 20, Issue 6, Page 572-589, December 2022., 2022
ABSTRACT The detection of mineral deposits and their related geological structures is of great importance to the mining industry as structures (such as dykes and faults) can affect the safety, cost and efficiency of mining. With the goal of testing cost‐effective seismic methods for mineral exploration and mining, active and passive seismic experiments

Decoding Variants of Pyrite, Arsenopyrite and Marcasite Using an Electron Counting Rule

Angewandte Chemie International Edition, Accepted Article.
Pyrite, Marcasite and Arsenopyrite are of significant historical and contemporary interest. Compounds adopting these structure types are extensively studied for their crystallographic properties and potential applications in energy storage and conversion.

Processes influencing heat transfer in the near-surface ice of Greenland's ablation zone [PDF]

The Cryosphere, 2018
To assess the influence of various heat transfer processes on the thermal structure of near-surface ice in Greenland's ablation zone, we compare in situ measurements with thermal modeling experiments.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Quasi-2D Resistivity Model from Inversion of Vertical Electrical Sounding (VES) Data using Guided Random Search Algorithm

Journal of Mathematical and Fundamental Sciences, 2015
Vertical electrical sounding (VES) data are usually interpreted in terms of a 1D resistivity model using linearized inversion. The local approach of a non-linear inverse problem has fundamental limitations, i.e. the necessity of a starting model close to

Brittle Deformation in the Neoproterozoic Basement of Southeast Brazil: Traces of Intraplate Cenozoic Tectonics

Geosciences, 2021
The basement of southeast Brazil is traditionally interpreted as the result of Neoproterozoic and early Paleozoic orogenic cycles. Wide regions of the Atlantic Plateau (southeast Brazil) are characterized by rocks and tectonic structures of Precambrian ...
