Spatial Regulation of Silicon Accumulation in Peduncle Confers Sheathed Spike in Barley

Plant Biotechnology Journal, EarlyView.
ABSTRACT Peduncle, the uppermost internode in cereals, connects the stem to the inflorescence and is critical for the transport of water, nutrients and photosynthetic assimilates. While peduncle length associates with plant height and its elongation is primarily regulated by phytohormones, we report a previously unrecognized mechanism involving the ...

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers

Sedimentology, EarlyView.
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.

Mid‐infrared spectroscopy applied to a multi‐level cave system (Montmaurin, SW France): An innovative method for assessing sediment provenance

Sedimentology, EarlyView.
ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

Emergence of Continents Stabilized the Bioavailability of Boron

Terra Nova, EarlyView.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

How much water is there within calcium silicate hydrates? Probing water dynamics by Inelastic Neutron Scattering and Molecular Dynamics Simulations

Calcium silicate hydrate (C-S-H) is a disordered, nanocrystalline material acting as the primary binding phase in Portland cement. Thin films of water are present on the surfaces and inside the nanopores of C-S-H and related phases such as calcium ...

Decalcification kinetics of calcium silicate hydrates: role of Al content, crystallinity, and initial pH

npj Materials Degradation
Calcium silicate hydrate (C-S-H) and calcium aluminum silicate hydrate (C-A-S-H) are the primary binding phases in Portland and blended cementitious systems, commonly retaining an amorphous to semi-crystalline structure.
