Fractionation of lead in soil by isotopic dilution and sequential extraction [PDF]
, 2011 ‘Reactivity’ or ‘lability’ of lead is difficult to measure using traditional methods. We investigated the use of isotopic dilution with 204Pb to determine metal reactivity in four soils historically contaminated with contrasting sources of Pb, including (

Giant Magnetostriction in Ferrimagnetic SmFe5As3
Angewandte Chemie International Edition, EarlyView.SmFe5As3 is a newly discovered ferrimagnetic material that displays peculiar volumetric effects as a function of temperature. As a result of two magnetic sublattices—one with d$d$‐electrons of Fe and another with f$f$‐electrons of Sm—single crystals of SmFe5As3 show negative (blue), positive (pink), and zero (beige) thermal expansion along the [010 ...

Journal of Central European Agriculture, 2005 The effect of system mineral and organic-mineral fertilization on the humus content and humus fractions in mollic fluvisols in condition of long-term fi eld experiment was studied. Forty years period of organic-mineral fertilization (N420P260K380 + 27 t/dka manure) have had stabilizing effect on humus content in the soil.

Бюллетень Почвенного института им. В.В. Докучаева, 2012 The group composition of humus in microaggregates (colloidal, pre-colloidal, fine, medium and coarse silt) of the soddy-podzolic medium-loamy soil has been first studied in three five-course grain-tilled crop rotations in the long-term experiment of V.V.

Effects of digestate on the environment and on plant production - results of a research project [PDF]
, 2008 Composts and digestates can influence soil fertility and plant health. These influences can be positive or negative, depending of the quality of the composts. A currently important question is to know, if digestates differ from composts in these aspects.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT A new type of thin‐film nanocomposite (TFN) membrane was synthesized by incorporating cellulose nanocrystals (CNCs) into a polyvinyl alcohol (PVA) top layer on a polycarbonate (PC) substrate via dip‐coating. The synthesized TFC and TFN membranes (PC/PVA TFC and PC/PVA‐CNC TFN membranes) were evaluated using contact angle measurement, field ...
