Pillared Clays: Preparation, Characterization and Applications
, 2007 Pillared Clays (PILCs) are an interesting class of 2-dimensional microporous materials. Due to their high surface area and permanent porosity they are very attractive solids for adsorption and catalysis purposes. Since their porosity can be localized in the larger micropore region, these substrates form a bridge between the microporous zeolites on one ...

Animal Segregation: The Biopolitics of Concentrated Pig Farming
Tijdschrift voor Economische en Sociale Geografie, EarlyView.Abstract This paper explores the possibility to think through the concept of animal segregation to understand the more‐than‐human geographies of livestock animals. By redirecting the analytical tools for studying the spatial separation of humans to the segregation of animals, this paper contributes to understanding the geographical processes of ...

Journal of Field Robotics, Volume 43, Issue 7, Page 4603-4623, October 2026.ABSTRACT Grass mowing is one of the most resource‐consuming activities in green maintenance, whether in private areas such as home gardens or in public spaces like urban parks. In recent years, concerns related to climate change, human health, and sustainability have become increasingly prominent in green maintenance, leading manufacturers and industry

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad
Journal of Anatomy, Volume 249, Issue 4, Page 924-949, October 2026.We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

Synthesis and characterization of delaminated iron-pillared clay with meso-microporous structure [PDF]
, 2006 In the present work, iron pillared clays were synthesized by the reaction of montmorillonite with base-hydrolyzed solutions of Fe(III) nitrate. In contrast with the classical microporous pillared structure, a novel meso-microporous delaminated structure ...

Journal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.Abstract Kenya's aquaculture sector is at a pivotal stage, transitioning from a historical reliance on Nile tilapia and African catfish toward a more diversified production portfolio that integrates indigenous and emerging freshwater and marine species. This shift is increasingly recognized as essential to enhance climate resilience, food security, and

Acidity in pillared clays: Origin and catalytic manifestations
, 1997 Acidity in pillared clays is a broad topic, and one which has been reviewed before [1-3]. Since it is difficult to be exhaustive, the present contribution is divided in two parts.
