Differences in available phosphorus evaluated by soil tests in relation to detection by colorimetric and ICP-AES techniques

Plant, Soil and Environment, 2010
Differences in the evaluation of soil phosphorus status by three soil tests (Mehlich 3, extraction with NH4-acetate and water extraction) were tested on 63 agricultural soils with different agrochemical characteristics from the territory of the Czech ...

A method for determining elements for elemental signature analysis of groundwater and treated Lake Mead water

, 1999
Elemental signature analysis (ESA) is a term that describes the use of the presence/absence or relative abundance of elements in samples. Several studies have been performed on the identification of these elemental signatures or fingerprints of water ...

Selective Separation of the Rare Earth Elements Dysprosium and Neodymium via Tailoring Nanocellulose Chemical Structure

Advanced Functional Materials, EarlyView.
Dicarboxylate‐modified anionic hairy cellulose nanocrystals exhibit a high selectivity for dysprosium(III) over neodymium(III). This selectivity arises from disordered dicarboxylate cellulose “hairs” that enable cooperative ionic coordination, hydrogen bonding, and strain‐induced conformational shrinkage.

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

Advanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

A Cu2+ (S = 1/2) Kagom\'e Antiferromagnet: MgxCu4-x(OH)6Cl2 [PDF]

, 2010
Spin-frustrated systems are one avenue for inducing macroscopic quantum states in materials. However, experimental realization of this goal has been difficult because of the lack of simple materials and, if available, the separation of the unusual ...
