1. 1. Stimuli-Responsive Materials Derived from Cellulose Nanofibrils : Synthesis, characterization, and performance evaluation

   Författare :Frédéric Héraly; Jiayin Yuan; Lennart Bergström; Leonid Ionov; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bio-based materials; cellulose nanofibrils; CO2 sorption; soft actuators; stimuli-responsive materials; materialkemi; Materials Chemistry;

   Sammanfattning : This thesis presents a comprehensive study on stimuli-responsive materials derived from cellulose nanofibrils (CNFs), focusing on their synthesis, characterization, and performance evaluation in various applications. Renowned for their biodegradability, renewability, and robust mechanical properties, CNFs are explored in three primary contexts: moisture-responsive actuators, voltage-responsive actuators, and CO2-responsive sensors.

   Nyckelord :Rainbow trout Oncorhynchus mykiss ; Shorthorn sculpin Myoxocephalus scorpius ; Diet composition; Oxygen consumption; Mechanical stimuli; Chemical stimuli;

   Sammanfattning : Henrik Seth (2010) On the Regulation of Postprandial Gastrointestinal Blood Flow in Teleost Fish Department of Zoology/Zoophysiology, University of Gothenburg, Box 463, 405 30 Göteborg. The regulation of the cardiovascular changes, in particular the increase in gastrointestinal blood flow that follows after feeding has received little attention in teleost fish. LÄS MER

4. 3. Apoptosis Regulation via the Mitochondrial Pathway : Membrane Response upon Apoptotic Stimuli

   Författare :Marc-Antoine Sani; Gerhard Grobner; Antoinette Killian; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Apoptosis; BH4 peptide; Bax-α1 peptide; model membrane; cardiolipin; solid phase peptide synthesis; circular dichroism; solid-state nuclear magnetic resonance spectroscopy.; Biophysics; Biofysik;

   Sammanfattning : The aim of this thesis was the investigation of the mitochondrial response mechanisms upon apoptotic stimuli. The specific objectives were the biophysical characterization of membrane dynamics and the specific roles of lipids in the context of apoptotic regulation occurring at the mitochondrion and its complex membrane systems.

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stimuli-responsiveness; dynamic covalent reactions; systems chemistry; constitutional dynamics; non-equilibrium systems; nitroaldol reaction; dynamers; reversible polymerization; boronate ester; imine ligand; metal coordination; self–assembly; emergent properties; network topology.; stimuli-responsivitet; dynamiska kovalenta reaktioner; systemkemi; konstitutionell dynamik; icke-jämviktssystem; nitroaldolreaktion; dynamerer; reversibel polymerisation; boronester; iminligand; metallkoordination; själv-organisation; emergenta egenskaper; nätverkstopologi.; Kemi; Chemistry;

   Sammanfattning : Nature tends to inspire research in chemistry. Systems that emerge from molecules interacting via reaction networks is something that life has mastered over the course of evolution in order to produce complexity. Dynamic reactions are key in systems chemistry, where reaction networks give rise to complex, emergent behavior. LÄS MER
