How Effective Are Cleaners With “Effective Microorganisms”?

Journal of Surfactants and Detergents, Volume 28, Issue 6, Page 1283-1295, November 2025.
ABSTRACT Microbial‐based cleaning products containing active microorganisms, such as Bacillus spores and “Effective Microorganisms” (EM)—a blend of lactic acid bacteria, photosynthetic bacteria, and yeast—are marketed for their potential to clean and displace pathogens. This study evaluated the efficacy of EM‐based cleaners by analyzing their microbial

Breeze of Continuity: New Evidence for the Occupation of Jumeirah Throughout the Islamic Period

Arabian Archaeology and Epigraphy, Volume 36, Issue 1, Page 306-327, November 2025.
ABSTRACT The Jumeirah Archaeological Research Project seeks to reassess the long‐term occupation of Jumeirah through an integrated study of three key archaeological sites—Jumeirah 1, 2 and 3. This study builds upon previous excavations and archival data to refine the chronology of the settlement and examine whether these sites functioned as a single ...

The Use of Ornamental Stone Waste (OSW) as Raw Material for Porcelain Ceramic Tiles Production

International Journal of Ceramic Engineering &Science, Volume 7, Issue 5, September 2025.
ABSTRACT Despite the relevant contribution of the ornamental stone industry to the international economy, the large volume of waste generated during the production process is one of the main problems faced by the sector. Currently, the ceramic industry has shown to be a powerful alternative for the use of these wastes.

Energy saving in sintering of porcelain stoneware tile manufacturing by using recycled glass and pottery stone as substitute materials

Case Studies in Thermal Engineering, 2018
Commercial porcelain stoneware tiles are vitrified tiles (noted as C) that are composed of clay, feldspar, and quartz. They require high temperature sintering at 1230 °C that result in high energy costs. This study aimed to compare the energy consumption

Effect of nanosilica and nanoboehmite in the pyroplastic deformation of a porcelain tile paste

International Journal of Applied Ceramic Technology, Volume 22, Issue 5, September/October 2025.
Abstract Porcelain tiles are low‐porosity ceramic coatings, formed by a mixture of clay minerals, quartz, and feldspars, and fired at temperatures close to 1200°C with formation of a liquid phase that can result in unwanted pyroplastic deformations. In addition, the rectangular formats, large dimensions, reduced thicknesses, and fast thermal cycles ...

Bricks and Concrete Wastes as Coarse and Fine Aggregates in Sustainable Mortars

Advances in Materials Science and Engineering, Volume 2018, Issue 1, 2018., 2018
The total substitution by volume of natural coarse calcareous aggregate by coarse recycled brick aggregate (RBA) and coarse recycled concrete aggregate (RCA) has been investigated to produce more sustainable and environment‐friendly mortars. Aggregates were also partially substituted by their fines at 12.5% by volume.
