Effects of macromolecular crowding and small ions on the folding, structure, and stability of Desulfovibrio desufuricans flavodoxin
… cells are ionic in nature, and although the Hofmeister series of ions has its origin in a work from 1888, much is still unclear concerning how small, charged ions affect protein properties. This thesis summarizes in vitro work assessing the effects of macromolecular crowding and small ions on …

Site-selective modification of cysteine residues
… and ion-specific following the Hofmeister series. Salts composed of early member ions in the Hofmeister series accelerate the reaction, while late members decrease the rate. To understand the unique self-labelling reactivity of the n-clamp tetrapeptide (Phe-Cys-Pro-Phe), …

Die Sturm-und-Drang-Bewegung und ihre Spezifika in den Dramen von Jakob Michael Reinhold Lenz und Heinrich Leopold Wagner
… of investigation were two particular works: Der Hofmeister by Jakob Michael Reinhold Lenz and Die Kindermörderin by Heinrich Leopold Wagner. The aim of the thesis is the find out how the specific characteristic of the movement Sturm und Drang is manifested in these works. The analysis of these …

The Aggregation Behavior of Mixture of Alkylmethylaminoxides with Their Protonated Analogues in Aqueous Solution
… curvature thus followed mostly the sequence of Hofmeister series, while the sulfuric ion was completely excluded from the series because of its divalency. The viscosity change was interpreted quantitatively by the hydration free energy (Delta-Ghyd) of counter-ion. However the divalent …

Ion specific effects on charged interfaces
… of the ‘ion specific effects’ dates back to Hofmeister (1888), who observed the specific effect of salts in promoting egg white proteins precipitation. Nowadays we are aware that ion specific effects are ubiquitous in all fields of science and technology where electrolytes play a role. Until …

Dinâmica molecular de micelas zwitteriônicas: estrutura, adsorção de íons e catálise
… adsorvem em ambas as micelas seguindo a série de Hofmeister direta: F⁻ < Cl⁻ < Br⁻ < I⁻ < ClO₄⁻. A proporção do número médio de ânions relativa ao ânion fluoreto é de 1 : 1,2 : 1,3 : 1,7 : 4,7 para a micela SB3-14 e 1 : 1,2 : 1,3 : 2,0 : 4,0 para a micela HPC mostrando que os íons perclorato …

Mathematical Modeling of Microscale Biology in Polyelectrolyte Brushes
… models that incorporate important ion-specific (Hofmeister) effects. The transient model enables observation of the relative physical effects as an initial non-equilibrium state relaxes to the steady state. The results quantify how electroneutrality is attained through diffusion, ion …

Ion binding to polymers and lipid membranes in aqueous solutions : Ionenbindung an Polymeren und Lipidmembranen in wässrigen Lösungen
… verwendet. Die Verdünnungswärmen konnten auf Hofmeister Effekte zurückgeführt werden. Im Anschluss daran wurde die Bindung von Ca2+ an Natrium- Poly(acrylsäure) (NaPAA) untersucht. Mit Hilfe von ITC und einer Ca2+- selektiven Elektrode wurde die Reaktionsenthalpie und Bindungsisotherme …

Specific ion effects on transient polymers: a new strategy for programmable microcapusles
… effect. Chapter 7 reviewed current topics on the Hofmeister effect and constructed a crude model on auto-catalytic microcapsules. The thesis research offers an encapsulation strategy and ion library for triggered release microcapsules and will be of significance for designing logic gate responsive …

The Effect of Peer Presence on Risk Taking Behavior Among Late Adolescents
The present study used an experimental method to examine risk-taking in a simulated environment involving risky driving behaviors. The study examined the effects of peer presence on risk-taking behavior among late adolescents and explored a potential mechanism of said effect, emotional arousal. …

Expression und immunmodulatorische Funktion von HLA-G und seinen verkürzten Isoformen in Tumorzellinien
Das nicht polymorphe HLA-Klasse-I-Antigen HLA-G wird hauptsächlich in der Plazenta exprimiert, wo es vermutlich den semiallogenen Fötus vor Angriff des mütterlichen Immunsystems schützt. Eine Besonderheit von HLA-G ist das Auftreten von mehreren verkürzten Isoformen, die von alternativ gespleißten …

Die Rückgewinnung von Feuchtgebieten als eine Lösung für aktuelle Umweltprobleme : Hemmnisse und Möglichkeiten
Feuchtgebiete sind Ökosysteme, die durch die Anwesenheit von Wasser, spezielle Bodenverhältnisse und eine besondere Vegetationszusammensetzung geprägt sind. Sie zählen zu den am stärksten bedrohten Ökosystemen der Erde. Im Verlauf des 20. Jahrhunderts nahm weltweit sowohl ihre Fläche als auch ihre …

A dynamic knowledge graph approach to creating interoperability in smart cities: Selected case studies towards holistic flood impact assessments and district heating operations
Modern cities leverage information and communication technology to enhance residents' quality of life, thereby evolving into increasingly ‘smart’ entities. Advancing digitalisation generates extensive data with the potential to address pressing environmental and social challenges, boost innovation, …

Transport phenomena in hydrogel membranes
… behaviour of the salts are made with the Hofmeister series. The effect of the chemical composition of the polymer backbone on the water structuring in the hydrogel and, consequently, transport through the membrane, was investigated by preparing a series of poly (2-hydroxyethyl …
