Dusty wind of W Hya. Multi-wavelength modelling of the present-day and recent mass-loss [PDF]
, 2015 Low- and intermediate-mass stars go through a period of intense mass-loss at the end of their lives in a phase known as the asymptotic giant branch (AGB). During the AGB a significant fraction of their initial mass is expelled in a stellar wind.

Cement and Concrete Research, 1972 Abstract Tricalcium silicate, bottle-hydrated tricalcium silicate and calcium hydroxide were each treated with 0.015–1.0% calcium lignosulfonate (CLS) using water or dimethyl sulfoxide. At low CLS concentrations C 3 S hydrates and irreversibly adsorbs CLS. At concentrations beyond about 0.25–0.35% the hydration of C 3 S is inhibited.

Advanced Materials Interfaces, EarlyView.This study explores the synthesis and properties of hafnium‐titanium oxide (HTO) alloys developed by low‐temperature atomic layer deposition (ALD) as selective contacts for crystalline silicon solar cells. X‐ray photoelectron spectroscopy (XPS), surface photovoltage (SPV), and ellipsometry are employed to estimate the band alignment at the c‐Si/HTO ...

Advanced Materials Interfaces, EarlyView.This study presents a novel silica‐based sol‐gel coating enhance with silica nanoparticles to protect glass surfaces. By reducing formulation acidity and improving resistance to environmental alteration—especially with 50 nm particles and double‐dip application—the method creates a gentle yet effective protective barrier.

Incorporation of aluminium in calcium-silicate-hydrates
Cement and Concrete Research, 2015 Calcium silicate hydrate (C-S-H) was synthetized at 20 °C to investigate the effect of aluminium uptake (Al/Si = 0–0.33) in the presence and absence of alkalis on the composition and the solubility of a C-S-H with a Ca/Si equal to 1.0.C-S-H incorporates aluminium readily resulting in the formation of C-A-S-H at Al/Si ≤ 0.1.

Advanced Materials Interfaces, EarlyView.This review explores how various surface pretreatment methods—such as heat treatment, severe plastic deformation, laser modification, immersion, and cold spray—enhance the performance of PEO coatings on magnesium alloys. The study highlights how these pretreatments influence coating microstructure, adhesion, and corrosion resistance, offering new ...

Predicting Young's Modulus of Glasses with Sparse Datasets using Machine Learning
, 2019 Machine learning (ML) methods are becoming popular tools for the prediction and design of novel materials. In particular, neural network (NN) is a promising ML method, which can be used to identify hidden trends in the data.

Synchrotron Radiation Pair Distribution Function Analysis of Gels in Cements [PDF]
, 2017 The analysis of atomic ordering in a nanocrystalline phase with small particle sizes, below 5 nm, is intrinsically complicated because of the lack of long-range order.

Calcium Silicate Board as Wall-facade
Procedia Engineering, 2017 Abstract Wall as spatial partition and facade of a building gives impact not only for building aesthetic, but especially for the occupant's convenience. In the preference of wall material, especially for high rise apartments, hotels or offices, its mass/m2 and its noise reduction become an important criteria that must be considered by the building ...

The Impact of DNA as a Chemical Admixture for Cementitious Materials
Advanced Materials Technologies, EarlyView.DNA molecules are added to cement pastes and their effects on rheology and hydration time are studied. DNA's chemical structure is composed of polysaccharide and phosphate groups, which are active functional groups in different commercial chemical admixtures: Viscosity modifiers and superplasticizers.
