A solid-state NMR method to determine domain sizes in multi-component polymer formulations

David Lyndon Emsley, Judith Schlagnitweit

Polymer domain sizes are related to many of the physical properties of polymers. Here we present a solid-state NMR experiment that is capable of measuring domain sizes in multi-component mixtures. The method combines selective excitation of carbon magnetiz ...

A Compressible Scaffold for Minimally Invasive Delivery of Large Intact Neuronal Networks

Philippe Renaud, Georg Fantner, Thomas Michael Braschler, Patrick Fraering, Oliver Peric, Amélie Barbara Hildegarde Béduer, Sébastien Mosser, Sidi Ahmed Bencherif

Millimeter to centimeter-sized injectable neural scaffolds based on macroporous cryogels are presented. The polymer-scaffolds are made from alginate and carboxymethyl-cellulose by a novel simple one-pot cryosynthesis. They allow surgical sterility by means ...

Application of Ionic Liquids in the Downstream Processing of Lignocellulosic Biomass

Paul Joseph Dyson, Zhaofu Fei, Ning Yan, Sviatlana Siankevich

Chemical transformations of lignocellulosic substrates to valuable platform chemicals are challenging as lignin and cellulose have high thermal and chemical stabilities. However, certain ionic liquids are able to dissolve and deconstruct biomass and, in th ...

UV-Cured Cellulose Nanofiber Composites with Moisture Durable Oxygen Barrier Properties

Yves Leterrier, John Christopher Plummer, Tommaso Nardi, Sylvain Cyril Claude Galland, Lars Berglund

Nanocomposites based on 10 to 60 vol % cellulose nanofibers (NFC) in a photopolymerizable hyperbranched acrylate matrix were prepared. Unmodified NFC and NFC chemically modified with a silane coupling agent and with ceric ammonium nitrate for direct polyme ...

Enhanced Conversion of Carbohydrates to the Platform Chemical 5-Hydroxymethylfurfural Using Designer Ionic Liquids

Paul Joseph Dyson, Rosario Scopelliti, Gabor Laurenczy, Zhaofu Fei, Ning Yan, Sviatlana Siankevich

5-Hydroxymethylfurfural (HMF) is a key platform chemical that may be obtained from various cellulosic (biomass) derivatives. Previously, it has been shown that ionic liquids (ILs) facilitate the catalytic conversion of glucose into HMF. Herein, we demonstr ...

Ethanol and lignin production from Brazilian empty fruit bunch biomass

Edgard Gnansounou, Jegannathan Kenthorai Raman

Brazil Government is promoting palm plantations to use degraded land for biofuels. Palm production is expected to increase 35 per cent in future and there would be profuse biomass available that needs to be handled efficiently. Therefore, in this study the ...

The microfluidic post-array device: high throughput production of single emulsion drops

Esther Amstad

We present a microfluidic device that enables high throughput production of relatively monodisperse emulsion drops while controlling the average size. The device consists of a two-dimensional array of regularly-spaced posts. Large drops of a highly polydis ...

Rational development of an electron-rich platinum nanocatalyst for the oxidation of 5-hydroxymethylfurfural into 2,5-furandicarboxilic acid under mild conditions

Paul Joseph Dyson, Zhaofu Fei, Ning Yan, Georgios Savoglidis, Sviatlana Siankevich

Valorization of lignocellulosic biomass for the production of commodity chemicals using various chemical methods continues to attract considerable attention. A wide and diverse range of different chemicals can be obtained from biomass and many different do ...

A pore-hindered diffusion and reaction model can help explain the importance of pore size distribution in enzymatic hydrolysis of biomass

Jeremy Luterbacher

Until now, most efforts to improve monosaccharide production from biomass through pretreatment and enzymatic hydrolysis have used empirical optimization rather than employing a rational design process guided by a theory-based modeling framework. For such a ...

Movement of Artificial Bacterial Flagella in Heterogeneous Viscous Environments at the Microscale

Lei Zhang

Swimming microrobots have the potential to be used in medical applications such as targeted drug delivery. The challenges for navigating microrobots in the human body lie not only in the viscosity of body fluids but also in the existence of different types ...
