Structure and Reactivity of N-Heterocyclic Alkynyl Hypervalent Iodine Reagents

Rosario Scopelliti, Jérôme Waser, Farzaneh Fadaei Tirani, Matthew Wodrich, Eliott Hugo Joran Le Du

Ethynylbenziodoxol(on)e (EBX) cyclic hypervalent iodine reagents have become popular reagents for the alkynylation of radicals and nucleophiles, but only offer limited possibilities for further structure and reactivity fine-tuning. Herein, the synthesis of ...

Light-induced assembly and disassembly of polymers with PdnL2n-type network junctions

Kay Severin, Cristian Pezzato, Cesare Berton, Rujin Li

Polymers containing PdnL2n complexes as network junctions were obtained by reaction of poly(ethylene glycol)-linked N-donor ligands with Pd2+. The addition of a metastable state photoacid renders the networks light sensitive, and gel–sol transitions can be ...

Modular soft robotic microdevices for dexterous biomanipulation

Francesco Stellacci, Mahmut Selman Sakar, Ahmet Bekdemir, Murat Kaynak, Ece Özelçi, Berna Ayse Özkale Edelmann, Lucio Feo Pancaldi-Giubbini, Raquel Filipa Penacho Parreira

We present a methodology for building biologically inspired, soft microelectromechanical systems (MEMS) devices. Our strategy combines several advanced techniques including programmable colloidal self-assembly, light-harvesting with plasmonic nanotransduce ...

Current trends and possibilities for exploitation of Grape pomace as a potential source for value addition

Edgard Gnansounou

Grape pomace (GP) is a low-value by-product that contains a significant amount of high value-added products. The huge amount of non-edible residues of GP wastes (seeds, skins, leaves and, stems) pro-duced by wine industries causes & rsquo; environmental po ...

A General and Facile Approach for the Electrochemical Reduction of Carbon Dioxide Inspired by Deep Eutectic Solvents

Paul Joseph Dyson, Dmitry Vasilyev

Deep eutectic solvents (DESs) were applied to the electrochemical CO2 reduction reaction (CO2RR). Choline-based DESs represent a non-toxic and inexpensive alternative to room-temperature ionic liquids (RTILs) as additives to the system or as electrolyte. F ...

Polymeric Micelles Loading Proteins through Concurrent Ion Complexation and pH-Cleavable Covalent Bonding for In Vivo Delivery

Francesco Stellacci, Suiyang Liao

Protein drugs have great potential as targeted therapies, yet their application suffers from several drawbacks, such as instability, short half-life, and adverse immune responses. Thus, protein delivery approaches based on stimuli-responsive nanocarriers c ...

An in-situ 3D micro-XRD investigation of water uptake by alkali-silica-reaction (ASR) product

Solène Anne-Lise Albinski

The ASR products in concrete have various chemical compositions. It is yet unclear whether and how these products develop micro-expansion upon moisture ingress. This paper presents a 3D in-situ observation of the crystallography and volume change of an ASR ...

Fluorinated surfactants in droplet-based microfluidics: Influence of their composition on the properties of emulsion drops

Gianluca Nicolas Etienne

Miniaturization has been a driving force in many areas of science and technology, most notably in the electronics industry. Droplet-based microfluidics, a methode to produce emulsion drops in a controlled way and at high-throughputs, enables the miniaturiz ...

Crossover between distinct symmetries in solid solutions of rare earth nickelates

Duncan Thomas Lindsay Alexander, Bernat Mundet

A strong coupling of the lattice to functional properties is observed in many transition metal oxide systems, such as the ABO(3) perovskites. In the quest for tailor-made materials, it is essential to be able to control the structural properties of the com ...

Development of functionalized alginate-based hydrogels to reduce fibrosis in the transplantation of microencapsulated cells

François Rémi Pierre Noverraz

Nowadays, the development of cell therapy relies mainly on the advances made toward cell microencapsulation which allows to evade the need for immunosuppression during cell transplantation. Among the materials considered for cell encapsulation, hydrogels d ...

Pulsatile Flow-Induced Fatigue-Resistant Photopolymerizable Hydrogels for the Treatment of Intracranial Aneurysms

Dominique Pioletti, Christophe Moser, Mahmut Selman Sakar, Andreas Schmocker, Lucio Feo Pancaldi-Giubbini, Oriane Poupart

An alternative intracranial aneurysm embolic agent is emerging in the form of hydrogels due to their ability to be injected in liquid phase and solidify in situ. Hydrogels have the ability to fill an aneurysm sac more completely compared to solid implants ...

Composite Double-Network Hydrogels To Improve Adhesion on Biological Surfaces

Dominique Pioletti, Pierre-Etienne Bourban, Christophe Moser, Andreas Schmocker, Azadeh Khoushabi, Peyman Karami, Céline Samira Wyss, Martin Broome

Despite the development of hydrogels with high mechanical properties, insufficient adhesion between these materials and biological surfaces significantly limits their use in the biomedical field. By controlling toughening processes, we designed a composite ...

Structure of Lipid Nanoparticles Containing siRNA or mRNA by Dynamic Nuclear Polarization-Enhanced NMR Spectroscopy

David Lyndon Emsley, Aaron James Rossini, Arthur César Pinon, Jasmine Viger-Gravel

Here, we show how dynamic nuclear polarization (DNP) NMR spectroscopy experiments permit the atomic level structural characterization of loaded and empty lipid nanoparticles (LNPs). The LNPs used here were synthesized by the microfluidic mixing technique a ...

Tailoring swelling to control softening mechanisms during cyclic loading of PEG/cellulose hydrogel composites

Dominique Pioletti, Pierre-Etienne Bourban, Baris Çaglar, Azadeh Khoushabi, Céline Samira Wyss

One of the novel approaches for discogenic lower back pain treatment is to permanently replace the core of the intervertebral disc, so-called Nucleus Pulposus, through minimally invasive surgery. Recently, we have proposed Poly(Ethylene Glycol) Dimethacryl ...
