The structure of [1b · 2tp] (tp=4-thiopyridone) consists of a three-dimensional, negatively charged host framework comprising (via Sn S bonds) one "aromatic" thione linkage and a [Me3Sn · tp]+guest ion involving a more zwitterionic form of tp.
It's not that we're invisible, but we are so often portrayed as single note, one-dimensional, or negatively.
BC with ultrafine three dimensional network was negatively charged by the adsorption of polyvinylpyrrolidone (PVP) to initiate the nucleation of HAp.
Despite the lack of a high-resolution structure for this domain, its approximate shape and dimensions can be obtained from either three-dimensional helical reconstructions of negatively stained Myo1A decorating F-actin [31] or two-dimensional crystals of Myo1A on negatively charged phospholipids [37].
We've come a long way since 1982's Atari 2600 rape-horror Custer's Revenge, but last year's Grand Theft Auto V attracted valid criticism for its negatively one-dimensional depictions of women as nagging bores, cheating harlots and cheap strippers.
In order to generate an initial three dimensional model of the negatively-stained PRC2 complex, 190 tilt-pair images (60° and 0°) were collected using the same imaging conditions as described in the previous section.
However, a further increment in the content of the boron compounds (12 wt.%) negatively affected the dimensional stability and mechanical properties of the coupled samples (6 wt.% MAPE), except for the modulus of elasticity.
On the basis of these studies, a mechanism of electropolymerization was proposed which suggests for the modifier film a one-dimensional, polymeric structure formed from a negatively charged platinum compound, stabilized by Cu2+ and Cu+ as the counter ions.
The best fitting model was one-dimensional with response bias on the negatively phrased items, suggesting that previous GHQ-12 factor structures were artifacts of the analysis method.
Schematic representation of the three-dimensional structure and surface charges (red: negatively charged; blue: positively charged) of two different views of AChE (a) and PrP (b).
Moreover, dimensional instability and porosity changes of scaffold can negatively affect cell attachment and infiltration into the scaffold (Ru et al. 2015).
