Plasma-sprayed Al₂O₃-TiB₂-SiC ternary composite coatings and its wear behaviour based on SiC content

This paper aims to study the effect of adding different SiC content on the wear performance of Al₂O₃-TiB₂-SiC ternary composite coatings produced by the air plasma spraying process. The study used SHS powders as primary materials, consisting of H₃BO₃, Al, and TiO₂, and 5, 10,...

Strength development and hydration progress of a cement-based solidifying agent used in cementtreated soil containing volcanic mineral components

This study investigates the relationship between the strength development and hydration progress of cement-based solidifying agents (CBSAs) in cement-treated soil with volcanic mineral components. A CBSA is a cement-based material used as a soil stabilizer. It is known that the strength development of cement-based materials is inhibited by...

Transient phase fraction and dislocation density estimation from in-situ X-ray diffraction data with a low signal-to-noise ratio using a Bayesian approach to the Rietveld analysis

We describe the analysis of in-situ HT-XRD data of a dual phase stainless steel exposed to a complex thermal cycle of heating, holding and cooling. For the conditions used only low quality diffraction data could be collected. Peak positions, peak areas and peak broadening are modeled by the Rietveld method. The low signal-to noise ratio and...

材料、颜色与空间: 博图斯·穆德的施罗德住宅修复理念

Rietveld Schröder House is one of the most representative work of the Dutch De Stijl movement. The house represents Mrs Schröder’s pursuit of a modern, open lifestyle. Moreover, it is also the first batch of restored modern architectural heritage, which is a milestone for Dutch and even worldwide architectural protection. Bertus Mulder is the...

An extraordinary photograph: Gerrit Rietveld, Mart Stam and El Lissitzky at the Schröder House, 1926

The Schröder House, designed in 1924 by Gerrit Th. Rietveld (1888-1964) in close<br/>collaboration with the client Truus Schröder-Schräder (1889-1985), has been<br/>photographed countless times.1 Most of the photographs of this well-known<br/>monument are architectural photographs, of its exterior or interior. Only a few<br/>of them include one...

Identification of Iron Carbides in Fe(−Na−S)/α-Al₂O₃ Fischer-Tropsch Synthesis Catalysts with X-ray Powder Diffractometry and Mössbauer Absorption Spectroscopy

In Fe-based Fischer-Tropsch Synthesis (FTS), the Fe carbides form under the carburizing H₂ : CO reaction atmosphere providing the active phases for hydrocarbon synthesis. H₂ reduced Fe(−Na−S)/α-Al₂O₃ catalyst materials, with and without Na−S promotion, were carburized under CO at 240–440 °C to form...

Authenticiteit, een geloofwaardig begrip?

Ruim veertig jaar geleden, in 1978, werd een nummer van het Bulletin knob gewijd aan de problematiek van de architectuurrestauratie. De bijdragen weerspiegelen de standpunten van de auteurs over restauratiefilosofie en -theorie en het is opvallend dat het begrip authenticiteit toen al centraal stond in het debat. Gekoppeld aan een ander begrip,...

Colour, Form and Space: Rietveld Schröder House Challenging the Future

The Rietveld Schröder House in Utrecht was designed in 1924 by Gerrit Thomas Rietveld (1888-1964) for Mrs Truus Schröder- Schräder (1889-1985), as a home for her and her three young children. Mrs Schröder had very decided ideas about the modern family, the upbringing of her children, and a corresponding way of living. She wanted a flexible house...

The Restorations of the Rietveld Schröder House: a reflection

The Rietveld Schröder House (1924) in Utrecht is the only private home among the ten UNE SCO World Heritage sites in the Netherlands. In 1987 it was opened to the public as a museum house and since 2013 it has been part of the collection of Utrecht's Centraal Museum. The world-famous house was designed by the architect Gerrit T. Rietveld ...

Revealing Lattice Expansion of Small-Pore Zeolite Catalysts during the Methanol-to-Olefins Process Using Combined Operando X-ray Diffraction and UV-vis Spectroscopy

In small-pore zeolite catalysts, where the size of the pores is limited by eight-ring windows, aromatic hydrocarbon pool molecules that are formed inside the zeolite during the Methanol-to-Olefins (MTO) process cannot exit the pores and are retained inside the catalyst. Hydrocarbon species whose size is comparable to the size of the zeolite...

Rietveld originals: Handle with care!

The work of architect Gerrit Th. Rietveld (1888 – 1964) is appreciated throughout the world. Many of the well-known buildings he designed have survived to the present. Some have been restored or refurbished, depending on the condition of the building, current needs of the building users, etc. Rietveld himself had a very clear vision about...
