Book ChapterDOI
Stabilization of Soil Organic Carbon as Influenced by Clay Mineralogy
Mandeep Singh,Binoy Sarkar,Binoy Sarkar,Subhas Sarkar,Jock Churchman,Nanthi Bolan,Sanchita Mandal,Manoj Menon,T.J. Purakayastha,David J. Beerling +9 more
TL;DR: In this paper, the authors review the existing knowledge of soil organic matter dynamics with special reference to the role of clay mineralogy in the retention and stabilization of organic carbon in soil.
Journal ArticleDOI
Biocompatible functionalisation of nanoclays for improved environmental remediation
Bhabananda Biswas,Laurence N. Warr,Emily F. Hilder,Nirmal Goswami,Mohammad Mahmudur Rahman,Jock Churchman,Krasimir Vasilev,Gang Pan,Ravi Naidu +8 more
TL;DR: A large number of promising nanoclay-based sorbents are yet to satisfy environmental biocompatibility in situ but opportunities are there to tailor them to produce "biocompatible" or regenerative/reusable materials.
Journal ArticleDOI
Adsorption-desorption behavior of dissolved organic carbon by soil clay fractions of varying mineralogy
Mandeep Singh,Binoy Sarkar,Binoy Sarkar,Bhabananda Biswas,Jock Churchman,Jock Churchman,Nanthi Bolan +6 more
TL;DR: In this article, a set of batch adsorption-desorption experiments were conducted using pedogenic clays extracted from soils dominated by kaolinite-illite (Kaol-Ill), smectite (Smec), and allophane (Allo).
Journal ArticleDOI
Structural, electrokinetic and surface properties of activated palygorskite for environmental application
Ruhaida Rusmin,Ruhaida Rusmin,Binoy Sarkar,Bhabananda Biswas,Jock Churchman,Yanju Liu,Yanju Liu,Ravi Naidu,Ravi Naidu +8 more
TL;DR: In this paper, palygorskite from Western Australia was activated through thermal (300 °C for 4 h), acid (4 M HCl for 2 h at 70 °C) and acid-thermal (acid treatment followed by heating at 300 °Cfor 4 h) treatments, and the structural and physicochemical characteristics were examined against the raw clay mineral.
Journal ArticleDOI
Clay amount and distribution influence organic carbon content in sand with subsoil clay addition
TL;DR: In this article, the authors compared the organic C (OC) stock in a range of clay-amended and unamended sandy soils under cereal cropping and identified factors that influence OC stock.
