3D Claying: 3D Printing and Recycling Clay

open access: yesCrystals, 2023
Clay is of great interest as a 3D printing material thanks to its ease of use, recyclability and reusability. This paper analyses the technical aspects of the whole printing process. The behaviour of 3D printing clay is studied with respect to the environment and its specific application as a temporary or definitive formwork system for cement parts ...

Clay mineralogy in mylonite weathering products from Njimom (west Cameroon): origin and terracotta suitability

open access: yesDiscover Geoscience
This study investigated the mineralogical assemblage of weathering products developed on mylonite rocks in west Cameroon. Smectite and vermiculite occurrence was studied, particularly to emphasize its origin and the potential of the samples in terracotta

Boric Acid Supported on Montmorillonites as Catalysts for Synthesis of 2,3-dihydroquinazolin-4(1H)-ones [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2019
Synthesis of 2,3-dihydroquinazolin-4(1H)-ones using H3BO3/montmorillonite K10 (H3BO3/mont K10) catalyst has been reported. H3BO3/mont K10 and H3BO3/mont K30 have been prepared and used as catalysts in the reaction between anthranilamide and benzaldehyde ...

Weathering microenvironments on feldspar surfaces: implications for understanding fluid-mineral reactions in soils [PDF]

open access: yes, 2008
The mechanisms by which coatings develop on weathered grain surfaces, and their potential impact on rates of fluid-mineral interaction, have been investigated by examining feldspars from a 1.1 ky old soil in the Glen Feshie chronosequence, Scottish ...

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

open access: yesFEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Temperature-dependent elastic shear modulus of a saturated lateritic clay [PDF]

open access: yesE3S Web of Conferences
The thermo-mechanical behaviour of saturated clays and sands has been studied by many researchers, considering that it is useful in many geotechnical problems, such as the analysis of energy foundations and the effects of climate change on earth ...

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

open access: yesAdvanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Bridging molecular and continuous descriptions: the case of dynamics in clays

open access: yesAnais da Academia Brasileira de Ciências, 2010
The theory of transport in porous media such as clays depends on the level of description. On the macroscopic scale,hydrodynamics equations are used.
