Lime-diatomic mortar for finishing the walls of buildings [PDF]

open access: yesНанотехнологии в строительстве, 2022
Introduction. At present, when performing finishing and restoration work, more and more preference is given to dry lime mixes (DBM). Wide opportunities for the production of dry lime-cement mixes are opened up by the use of diatomite, which is both a dry

Polygalacturonase activity promotes aberrant cell separation in the quasimodo2 mutant of Arabidopsis thaliana

open access: yesThe Cell Surface, 2022
In plants, cell adhesion relies on balancing the integrity of the pectin-rich middle lamella with wall loosening during tissue expansion. Mutation of QUASIMODO2 (QUA2), a pectin methyltransferase, causes defective hypocotyl elongation and cell adhesion ...

Saccharide analysis of onion outer epidermal walls

open access: yesBiotechnology for Biofuels, 2021
Background Epidermal cell walls have special structural and biological roles in the life of the plant. Typically they are multi-ply structures encrusted with waxes and cutin which protect the plant from dehydration and pathogen attack.

Temperature-Dependent Crystallization Mechanisms of Methylammonium Lead Iodide Perovskite From Different Solvents

open access: yesFrontiers in Energy Research, 2021
Hybrid perovskites are a novel type of semiconductors that show great potential for solution-processed optoelectronic devices. For all applications, the device performance is determined by the quality of the solution-processed perovskite thin films ...

Warm Dark Matter in Simulations

open access: yesUniverse, 2022
In recent years, warm dark matter models have been studied as a viable alternative to the cold dark matter models. The warm dark matter particle properties are expected to imprint distinct signatures on the structure formation at both large and small ...

Preparation of Onion Epidermal Cell Walls for Imaging by Atomic Force Microscopy (AFM)

open access: yesBio-Protocol, 2017
The growing plant cell wall is comprised of long, thin cellulose microfibrils embedded in a hydrated matrix of polysaccharides and glycoproteins. These components are typically constructed in layers (lamellae) on the inner surface of the cell wall, i.e.,
