Removal of Cd and Pb with biochar made from dairy manure at low temperature
Journal of Integrative Agriculture, 2019 Biochar (BC) derived from waste products is a cost-effective sorbent for remediation of metal-contaminated soils. We studied the kinetics and adsorption mechanisms for removal of metal ions, such as lead (Pb2+) and cadmium (Cd2+) with biochar.

Discrete isothermic surfaces. [PDF]
Journal für die reine und angewandte Mathematik (Crelles Journal), 1996 Discrete isothermic surfaces are defined as the maps \(F: \mathbb{Z}^2\to \mathbb{R}^3\) such that all elementary quadrilaterals of the surface have cross ratio \(-1\). It is shown that these discrete surfaces possess properties which are characteristic for smooth isothermic surfaces (Möbius invariance, dual surface).

Destabilization of free convection by weak rotation [PDF]
, 2011 This study offers an explanation of a recently observed effect of destabilization of free convective flows by weak rotation. After studying several models where flows are driven by a simultaneous action of convection and rotation, it is concluded that ...
