Vibrational characterization of different benzene phases on flat and vicinal Si(100) surfaces
(2007-10-17)Based on high-resolution electron energy loss spectroscopy and temperature-programmable desorption, benzene chemisorption on vicinal and nominally flat Si 100 surfaces has been studied for various adsorption, annealing, ... -
Synthesis of cyclic guanidines: 2-arylamino-1,4,5,6-tetrahydropyrimidines
(2014)Considering the biological and chemical relevance of guanidine containing derivatives, we have devised a novel and efficient two-step synthesis of 2-arylamino-1,4,5,6-tetrahydropyrimidines. We have found that the coupling ... -
"Poisson's ratio of individual metal nanowires"
(2014)The measurement of Poisson's ratio of nanomaterials is extremely challenging. Here we report a lateral atomic force microscope experimental method to electromechanically measure the Poisson's ratio and gauge factor of ... -
Heterojunction hybrid devices from vapor phase grown MoS 2
(2014)We investigate a vertically-stacked hybrid photodiode consisting of a thin n-type molybdenum disulfide (MoS2) layer transferred onto p-type silicon. The fabrication is scalable as the MoS2 is grown by a controlled and ... -
Crystal structure of [5-n-butyl-10-(2,5-dimethoxyphenyl)-2,3,7,8,12,13,17,18-octaethylporphyrinato]nickel(II)
(2015)The asymmetric unit of the title nickel(II) porphyrin, [Ni(C48H60N4O2)], contains one independent molecule. The average Ni—N bond length is 1.917 (13) A˚ . The molecules are arranged in a closely spaced lattice structure in ... -
Getting it right: 3D cell cultures for the assessment of photosensitizers for photodynamic therapy
(2015)Core quote “Cancer drug screening is rapidly moving towards the use of 3D cell models. The added complexity of PDT action makes this a conditio sine qua non for the screening of new photosensitizers.” -
Conformational control of cofactors in nature The influence of protein-induced macrocycle distortion on the biological function of tetrapyrroles
(2015)Tetrapyrrole‐containing proteins are one of the most fundamental classes of enzymes in nature and it remains an open question to give a chemical rationale for the multitude of biological reactions that can be catalyzed ... -
Crystal structure of 4-(methoxycarbonyl)phenylboronic acid
(2015)In the title compound, C8H9BO4, the methoxycarbonyl group is rotated out of the plane of the benzene ring by 7.70 (6)°. In the crystal, molecules are linked via pairs of O—H⋯O hydrogen bonds, involving the boronic acid ... -
Specific Drug Formulation Additives: Revealing the Impact of Architecture and Block Length Ratio
(2015)Combining poly(ethylene glycol) (PEG) with sequence-defined peptides in PEG-peptide conjugates offers opportunities to realize next-generation drug formulation additives for overcoming undesired pharmacological profiles ... -
Recent advances in the development of synthetic chemical probes for glycosidase enzymes
(2015)The emergence of synthetic glycoconjugates as chemical probes for the detection of glycosidase enzymes has resulted in the development of a range of useful chemical tools with applications in glycobiology, biotechnology, ... -
Intramolecular thiol-yne cyclisation as a novel strategy for thioglycal synthesis
(2015)A novel intramolecular thiol–yne cyclisation strategy has been developed for the synthesis of thioglycals. Both ionic and radical mediated cyclisation pathways have been investigated for D- and L-sugars. The ionic cyclisation ... -
Comments on reactions of oxide derivatives of uranium with hexachloropropene to give UCl4
(2015)We report that U3O8, UO2(NO3)2·6H2O, and UO2Cl2 react with hexachloropropene (HCP) to give UCl4 in 60, 100, and 92% yields, respectively, and report a protocol to recycle the HCP. This renders the preparation of UCl4 more ... -
Towards multifunctional lanthanide-based metal-organic frameworks
(2015)We report the synthesis, structure and physicochemical attributes of a new holmium(III)-based metal–organic framework whose 3D network structure gives rise to porosity; the reported structure-type can be varied using a ... -
Influence of fluoro and cyano substituents in the aromatic and antiaromatic characteristics of cyclooctatetraene
(2015)An exhaustive and systematic study of the structural and electronic properties of cyclooctatetraene (COT) upon substitution of hydrogen atoms by fluoro and cyano groups has been carried out in order to analyse the influence ...
