(2,3,7,8,12,13,17,18-Octa-ethyl-5-phenyl-porphyrinato)platinum(II).
(2011)The title compound, [Pt(C42H48N4)], was obtained through metallation of the corresponding free base with PtCl2, followed by crystallization from methylene chloride/methanol. The molecule exhibits an almost planar macrocycle ... -
2D foams above the jamming transition: Deformation matters
(2017)Jammed soft matter systems are often modelled as dense packings of overlapping soft spheres, thus ignoring particle deformation. For 2D (and 3D) soft disks packings, close to the critical packing fraction ϕc, this results ... -
3-Urea-1,8-naphthalimides are good chemosensors: a highly selective dual colorimetric and fluorescent ICT based anion sensor for fluoride
(2011)he 1,8-naphthalimide sensor 1 was developed as a colorimetric and fluorescent sensor for anions. Being the first example of such anion sensors, where the 3-position of the naphthalimide ring is used to incorporate the anion ... -
3D Printed Sugar-Sensing Hydrogels
(2020)The ability of boronic acids to reversibly bind diols, such as sugars, has been widely studied in recent years. In solution, through the incorporation of additional fluorophores, this boronic acid-sugar interaction can be ... -
{4,6-Bis[(E)-1-methyl-2-(pyridin-2-yl-methyl-idene-κN)hydrazinyl-κN]pyrimidine-κN}dichloridocopper(II) methanol disolvate monohydrate
(2011)The title compound, [CuCl2(C18H18N8)]?2CH3OH?H2O, contains a pentacoordinated Cu(II) atom bonded to the tridentate 4,6-bis[(E)-1-methyl-2-(pyridin-2-ylmethylidene)hydrazinyl]pyrimidine ligand and two Cl atoms. The geometry ... -
(5,15-Dianthracen-9-yl-10,20-dihexyl-porphyrinato)nickel(II): A planar nickel(II) porphyrin
(2010)The title compound, [Ni(C60H52N4)], is an example of a meso tetrasubstituted nickel(II) porphyrin with both meso aryl and alkyl residues. The molecule exhibits a planar macrocycle with an average deviation of the 24 ... -
Ab initio calculation of the biasdependent transport properties of Mn12 molecules
(2009)The bias-dependent transport properties of a device constructed by sandwiching a Mn 12 single molecule magnet between gold electrodes are investigated within an ab initio framework combining the nonequilibrium Green?s ... -
Ab initio transport across bismuth selenide surface barriers.
(2014)We investigate the effect of potential barriers in the form of step edges on the scattering properties of Bi2Se3(111) topological surface states by means of large-scale ab initio transport simulations. Our results demonstrate ... -
ACC and vaterite as metastable intermediates in the solution based crystallization of CaCO3
(Springer International Publishing, 2017)Amorphous calcium carbonate (ACC) and vaterite are not very common in abiotic systems, but they play a very significant role in biomineralization processes and are key in the global carbon cycle. Despite their importance, ... -
Acceptance angle influence on optimum incident spot size for high-finesse microcavity two-photon absorption photodetectors
(2009)The influence of the limited acceptance angle of a high-finesse microcavity two-photon absorption photodetector on its response has been investigated. It is shown that the limited acceptance angle of the microcavity ... -
Accounting for the Local Field When Determining the Dielectric Loss Spectra of Metals in the Region of the Frequencies of Volume, Surface, and Localized Plasmon Oscillations
(2020)The optical constant of bulk metal is used to determine the dispersion of the local field under one-dimensional (1D), two-dimensional (2D) and three-dimensional (3D) confinement. 3D confinement, expressed as ε 2 m i c ( ω ... -
Activation behaviour and dielectric relaxation in polyvinyl alcohol and multiwall carbon nanotube composite films
(2011)The dc and ac electrical transport property of Polyvinyl Alcohol-Multiwall Carbon Nanotubes (PVA-MWNT) composites has been investigated within a temperature range 77?T?300K and in the frequency range 20Hz to 1MHz. The ... -
Adsorption of common solvent molecules on graphene and MoS2 from first-principles
(2018)Solvents are an essential element in the production and processing of two-dimensional (2D) materials. For example, the liquid-phase exfoliation of layered materials requires a solvent to prevent the resulting monolayers ... -
Advanced Separation Processes for Recovery of Critical Raw Materials From Renewable and Waste Resources
(Elsevier, 2019)Driven by the fact that global mineral reserves are constantly depleting, systematic mandates and policies have been initiated to augment the recovery of essential resources, which have been categorised as critical raw ...
