The influence of pH, ionic strength, presence of humic or alginic acids, extracellular polymeric substances (EPS), or freshwater microalga Chlorella kesslerii on the stability and transformation of carboxyl-PEG-CdSe/ZnS core/shell quantum dots (QDs) in ter ...
Ionic liquids pose challenges and provide solutions for electrospray ionisation mass spectrometry (ESI-MS). Being inherently charged, they are themselves easy to characterise in both positive- and negative-ion mode by ESI-MS, but the challenge arises when ...

Hybrid integration and especially the packaging of microelectromechanical systems (i.e. MEMS) cannot rely on standardised packaging solutions due to the diversity of microsystems. As an example, the packaging requirements of a pressure sensor are different ...

The connection of three tridentate 2,6-bis(1-ethyl-benzimidazol-2-yl)pyridine binding units to an extended sulfurcontaining tripodal anchor in the ligand L9 yields nine-coordinate podates [Ln(L9)]3+ upon reaction with trivalent lanthanides, Ln(III). Struct ...
We have characterized the polymer physics of single-stranded DNA (ssDNA) using atomic force microscopy. The persistence length l(p) of circular ssDNA adsorbed on a modified graphite surface was determined independently of secondary structure. At a very low ...
In light of the already proven applications of transition-metal (TM) oxide clusters, including catalysis, selective sorption, sepns., mol. recognition, environmental decontamination, and nanotechnol., one can imagine that the development of framework mater ...
Humic substances (HS) play an important role in the reactivity and transport of colloids in natural environments. In particular, the presence of fulvic acids (FA) in natural waters modifies the interactions between inorg. particles and biopolymers and make ...
The structure of ultrathin NaCl films on Au(1 1 1) and on Au(11 12 12), as well as the one of bimolecular 3,4,9,10-perylenetetracarboxylic diimide (PTCDI) and 1,4-bis-(2,4-diamino-1,3,5,-triazine)-benzene (BDATB) islands on NaCl films on both surfaces have ...
A series of lanthanide complexes [LnClx(bpy)y(H2O)z]Cl3-x(H2O)n(EtOH)m (Ln ) Eu, Gd, Tb; x ) 1, 2; y ) 1, 2; z ) 2-4) with different numbers of 2,2′-bipyridine (bpy), chloride ions, and water molecules in the inner coordination sphere were synthesized and ...
