Investigation of the effect of a multicomponent additive on the structure formation and hardening of cement composites

Конденсированные среды и межфазные границы, 2022
The development and application of multicomponent multifunctional additives for cement composites is an important research area since the use of such additives allows controlling both the rheological properties of the freshly prepared mixture and the ...

Sub-structure formation in starless cores [PDF]

, 2017
Motivated by recent observational searches of sub-structure in starless molecular cloud cores, we investigate the evolution of density perturbations on scales smaller than the Jeans length embedded in contracting isothermal clouds, adopting the same ...

Domain swaps of Arabidopsis secondary wall cellulose synthases to elucidate their class specificity

Plant Direct, 2018
Cellulose microfibrils are synthesized by membrane‐embedded cellulose synthesis complexes (CSCs), currently modeled as hexamers of cellulose synthase (CESA) trimers.

Structure formation and characteristics of chromium carbide–iron–titanium cermets; pp. 138–143 [PDF]

Proceedings of the Estonian Academy of Sciences, 2016
Structure formation and properties of chromium carbide-based cermets with iron–titanium binder were investigated. Chromium carbide (50–70 wt%), Fe, and Ti (Fe : Ti ratio 4 : 1 as the binder phase) powders were milled in an attritor and a ball ...

On the phase transition in a magnetic colloid under the action of electric field

Наука. Инновации. Технологии, 2022
The phase stratification and structural organization in a thin layer of magnetic fluid under the action of a constant electric field are studied. The analysis of the causes of the observed phase stratification was made on the basis of the model of the ...

Disk formation and structure [PDF]

EPJ Web of Conferences, 2015
In this chapter, we cover the formation of protoplanetary disk as a natural byproduct of the gravitational collapse of a slowly rotating, hydrostatic cloud. We also summarise the structure of such a disk as it results from hydrostatic equilibrium and viscous accretion.

Constraining structure formation using EDGES [PDF]

Journal of Cosmology and Astroparticle Physics, 2020
The experiment to detect the global epoch of reionization signature (EDGES) collaboration reported the detection of a line at 78MHz in the sky-averaged spectrum due to neutral hydrogen (HI) 21-cm hyperfine absorption of cosmic microwave background photons at $z\sim 17$. This requires that the spin temperature of HI be coupled to the kinetic temperature

Structure formation in the «clay soil – carbide sludge» dispersed system [PDF]

Нанотехнологии в строительстве
Introduction. Clay soil is a multiphase, multicomponent aluminosilicate dispersed system with specific properties determined not only by its composition but also by the formation of coagulative and transition contacts (binds) between the soil particles ...

Scenarios of structure formation in ternar nanoparticles based on Pd-Pt in the presence of dopant Ni

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2023
In this work, scenarios of structure formation in ternary nanoparticles based on platinum and palladium of four stoichiometric compositions of different sizes were studied, with nickel acting as a dopant.
