Optimising ice flow law parameters using borehole deformation measurements and numerical modelling

open access: yesGeophysical Research Letters, 2008
Internal ice strain rates have been measured along two boreholes drilled through Glacier de Tsanfleuron, Switzerland. Differences between these measurements and the output from a 3D numerical model of glacier motion have been minimized by a scheme that ...

On the rheology of dense pastes of soft particles [PDF]

open access: yes, 2008
textMany concentrated paste-like materials are composed of deformable particles randomly packed into a dense suspension. Examples of the constituent soft particles include polyelectrolyte microgels, emulsion droplets, polymer coated colloids, and star ...

Concentration effects in the rheology of cement pastes: Krieger-Dougherty revisited [PDF]

open access: yes, 2011
Cement pastes are concentrated suspensions of granular particles in water and their rheology strongly affects the behaviour of all concretes and other cementitious materials.

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Sol-gel transition of aqueous chitosan-ßglycerophosphate solutions

open access: yes, 2019
Hydrogels represent reliable systems for the delivery of drugs, including those based on nucleic acids. Indeed, hydrogel nature, structure, and response to physiological or external stimuli strongly influence the delivery mechanisms of entrapped active ...

Fundamentals, Advances, and Applications of Electrospun Nanofibrous 3D Materials

open access: yesJournal of Applied Polymer Science, EarlyView.
Three‐dimensional electrospun nanofibrous systems offer unique properties and microenvironments. These properties are determined by the fabrication strategies employed and can be adjusted by the incorporation of functional additives to achieve multifunctionality for specific applications. The applications range from the biomedical to the environmental,

Impact of Agitation Power Input on Aspergillus oryzae Metabolism: Application of Multi‐Omics on an Industrial Enzyme Fermentation

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT The agitation power input substantially impacts the oxygen transfer rate in aerobic fermentation processes. Furthermore, in a carbon‐limited process where the substrate feed rate is controlled by the concentration of dissolved oxygen, the power input will consequently govern the feed rate.

Scalable Separation and Purification of M13‐Bacteriophage‐Derived Particles Containing Artificial Single‐Stranded DNA Produced by Escherichia coli

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Single‐stranded DNA (ssDNA) solutions are promising innovations shaping the future of genetic research and medical therapies. In principle, biotechnological mass production of ssDNA can be achieved using Escherichia coli in a high‐cell density fed‐batch process by secreting phagemid particles derived from the filamentous M13 bacteriophages ...
