Model predictive control with inline parameter adaptation for direct crystal growth rate regulation
AIChE Journal, EarlyView.Abstract In batch cooling crystallization, many interactive factors, including supersaturation, reactor dimensions, and operating conditions, govern crystal growth and significantly influence product properties. Variables such as temperature or refractive index are used as surrogate control variables but have limitations in capturing growth rate ...

Stability of excavations and design of mining layouts in a deep level potash mine [PDF]
, 1980 PhD ThesisThe shafts at Boulby Potash Mine were sunk between 1969 and 1974 and the first potash was put through the processing plant in 1973. The decision to mine the deposit was based on the results obtained from fifteen exploration boreholes put ...

Corporate ESG Greenwashing: Does Regulatory Proximity Matter?
Business Strategy and the Environment, EarlyView.ABSTRACT Environmental, social, and governance (ESG) greenwashing undermines sustainable development, yet the influence of regulatory proximity on oversight is understudied. By introducing the “distance decay effect” from geoeconomics into ESG misconduct research and using a sample of Chinese listed firms from 2009 to 2022, this study reveals a ...

ChemSusChem, Volume 18, Issue 6, March 15, 2025.The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Geological Journal, EarlyView.Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Resolving the Conflict between Mining and Sustainability
Applied Environmental Research, 2019 Mining is essential for human health and prosperity, and is increasing as the global population grows. The need for minerals appears to conflict with what is commonly understood as ‘sustainability’, as geological resources are non-renewable on a human ...
