AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The limit of applicability of the monomer-enhanced mechanism as dominant mechanism ruling the initiation process of the polymerization of acrylamide (AM) initiated with potassium persulfate (K2S2O8) has been determined The kinetics and mechanisms for radic ...

π−π interactions in heteroaromatic systems are ubiquitous in biological systems. In the present study, stabilization energies of stacked and hydrogen-bonded dimers of N-heteroaromatic systems (pyridine, pyrazine, sym-triazine, and sym-tetrazine) have been ...
Previously we reported emulsion polymerization of propylene sulfide with Pluronic F127 as an emulsifier, yielding nanoparticles (NPs) in the 25 nm size range. Immunologically functional NPs were prepared by adding an antigen Pluronic conjugate to the polym ...
Aliphatic polyesters receive increasing attention over the last years driven by their application as biodegradable substitutes for conventional commodity thermoplastics and applications in the biomedical field, where amongst the family of biodegradable pol ...
Hydrogels are cross-linked, water-swollen polymer networks. Hydrogels with high mechanical and viscous dissipation properties are of great interest for mechanically control drug release systems. Since hydrogels are 3D polymer network with high amount of wa ...
This contribution explores different strategies for the synthesis of side chain functional polydepsipeptides. First, the ring-opening polymerization of side chain functional morpholine-2,5-diones is revisited and the optimized reaction conditions used for ...
Background - Nucleus pulposus degeneration is a very common musculo-skeletal pathology, which is in part responsible for low back pain, a pandemic medical problem. Artificial hydrogels are being investigated by research group around the world for the purpo ...
Aggregation and fibril formation of amyloid-β (Aβ) peptides play a pivotal role in the pathogenesis of Alzheimer's disease (AD). Aβ peptides, principally comprising of 40 or 42 amino acid residues (Aβ40 and Aβ42), are produced by proteolytic processing of ...
Proteins have been modified with polymers in diverse manners over the past 30 years. However, while proteins have been used to prepare many functional constructs, they are sensitive biomolecules and their bioactivity can be either positively or negatively ...
The development of innovative bioanalytical technologies that enable the discovery of new therapeutics or the creation of systems for rapid, accurate and parallel analyses has gained an extraordinary interest in the biomedical sector in the last 10-15 year ...
