The role of the local environment on the structural heterogeneity of carotenoid β-ionone rings KU Leuven
Our analysis of the X-ray crystal structure of canthaxanthin (CAN) showed that its ketolated β-ionone rings can adopt two energetically equal, but structurally distinct puckers. Quantum chemistry calculations revealed that the potential energy surface of the β-ionone ring rotation over the plane of the conjugated π-system in carotenoids depends on the pucker state of the β-ring. Considering different pucker states and β-ionone ring rotation, we ...
Probing Noncovalent Interactions in [3,3]Metaparacyclophanes KU Leuven
Arene-arene interactions are fundamentally important in molecular recognition. To precisely probe arene-arene interactions in cyclophanes, we designed and synthesized (2,6-phenol)paracyclophanes and (2,6-aniline)paracyclophanes that possess two aromatic rings in close proximity. Fine-tuning the aromatic character of one aromatic ring by fluorine substituents enables investigations on the intramolecular interactions between the electron-rich ...
Quick EXAFS measurements at SAMBA-SOLEIL:Cu K and Ce LIII edge Ghent University
Red noise in steady-state multiphase flow in porous media Ghent University
Biogenic nanoparticles and microbial cultures: a promising combination for the treatment of micropollutants Ghent University
Rising standards of living and continuous population growth has been leading to an increasing pressure on the environment. The accumulating water pollution and imminent water scarcity has become a global issue and has resulted in water becoming a limited resource (Verstraete et al. 2009). To cope with these challenges, people are forced to close the watercycle and reuse wastewater as potable water. Besides an increase in our quality of life, ...
Kinematics of mouthbrooding in Oreochromis niloticus (Cichlidae) Ghent University University of Antwerp
Many species from several different families of fishes perform mouthbrooding, where one of the sexes protects and ventilates the eggs inside the mouth cavity. This ventilation behaviour differs from gill ventilation outside the brooding period, as the normal, small-amplitude suction-pump respiration cycles are alternated with actions including near-simultaneous closed-mouth protrusions and high-amplitude depressions of the hyoid. The latter is ...
Acromioclavicular joint acceleration-deceleration injury as a cause of persistent shoulder pain : outcome after arthroscopic resection Ghent University
Background: Shoulder pain in general and acromioclavicular joint (ACJ) pain specifically is common after acceleration-deceleration injury following road traffic accident (RTA). The outcome of surgical treatment in this condition is not described in the literature. The aim of the present study was to report the outcome of arthroscopic resection of the ACJ in these cases. Materials and Methods: Nine patients with localized ACJ pain, resistant to ...
High quality NH2SAM (Self Assembled Monolayer) diffusion barrier for advanced copper interconnects KU Leuven
In this work, the quality of an amino-terminated SAM barrier (NH2SAM) is tested. A high density and the absence of pinholes in the barrier layer are essential for a good barrier performance in the copper interconnects. The quality of the NH2SAM layer has been assessed by water contact angle (C.A) and High resolution AFM (HR-AFM). The density and the closure of the film have been monitored by X-Ray Reflectivity (XRR), Ellipsometry and Cylic ...
Stability of mixed PEO-thiol SAMs for biosensing applications KU Leuven
The secret of a successful affinity biosensor partially hides in the chemical interface layer between the transducer system and the biological receptor Molecules. Over the past decade, several methodologies for the construction of such interface layers have been developed on the basis of the deposition of self-assembled monolayers (SAMs) of alkanethiols on gold. Moreover, mixed SAMs of polyethylene oxide (PEO) containing thiols have been applied ...
