Boron nitride microsphere/epoxy composites with enhanced thermal conductivity

open access: yesHigh Voltage, 2017
As modern electronics are developed towards miniaturisation, high-degree integration and intelligentisation, a large amount of heat will be generated during the operation of devices.

Filled polymers for bearings and seals used in liquid hydrogen [PDF]

open access: yes, 1970
Filled polytrifluorochloroethylene /PTFCE/ shows better thermal stability, less creep, and higher compressive moduli than filled polytetrafluoroethylene /PTFE/.

Phase behavior and structure of model colloid-polymer mixtures confined between two parallel planar walls

open access: yes, 2006
Using Gibbs ensemble Monte Carlo simulations and density functional theory we investigate the fluid-fluid demixing transition in inhomogeneous colloid-polymer mixtures confined between two parallel plates with separation distances between one and ten ...

How to combine a hydrophobic matrix and a hydrophilic filler without adding a compatibilizer – Co-grinding enhances use properties of renewable PLA-starch composites [PDF]

open access: yes, 2012
In order to avoid the use of compatibilizers or plasticizers, co-grinding was performed to produce PLA – starch composite materials. Fragmentation and agglomeration phenomena were analysed to propose a production mechanism.

Microfluidic electro‐viscoelastic manipulation of extracellular vesicles

open access: yesFEBS Open Bio, EarlyView.
The electro‐viscoelastic manipulation as a potential method for separation of particles based on size. The particles introduced as a sheath flow migrate to the channel center under the influence of simultaneously applied electric field and pressure driven flow.

Surface-modified barium titanate by MEEAA for high-energy storage application of polymer composites

open access: yesHigh Voltage, 2016
In this study, 2-[2-(2-methoxyethoxy)ethoxy]acetic acid (MEEAA) was used to modify the surface of barium titanate nanoparticles (BT NPs) to enhance the compatibility and dispersion of the BT ceramic fillers in polymer matrix. A uniform coating layer with

Nonlinear optical response from excitons in soliton lattice systems of doped conjugated polymers

open access: yes, 1995
Exciton effects on conjugated polymers are investigated in soliton lattice states. We use the Su-Schrieffer-Heeger model with long-range Coulomb interactions.

Diffusion‐based size determination of solute particles: a method adapted for postsynaptic proteins

open access: yesFEBS Open Bio, EarlyView.
We present a diffusion‐based approach for measuring the size of macromolecules and their complexes, and demonstrate its use on postsynaptic proteins. The method requires fluorescein‐labelled protein samples, a microfluidic device that maintains laminar flow for said samples, a microscope recording the emitted fluorescent signals, and an analytic ...

Biodegradable hollow fibres for the controlled release of hormones [PDF]

open access: yes, 1987
Poly(l-lactide), (PLLA), hollow fibres were prepared using a dry-wet phase inversion spinning process. The effect of several spinning parameters (i.e. bore medium flow rate, spinning dope extrusion rate, fibre take-up rate, and spinning height) on the ...

Using a Supramolecular Approach to Engineer Modular Hydrogel Platforms for Culturing Protoplasts – from General Tissue Engineering to Cellular Agriculture

open access: yesAdvanced Biology, EarlyView.
Using supramolecular monomers, various hydrogel culture systems were formulated to culture protoplasts; including 2D, 2.5D, and 3D hydrogels. Depending on the culture platform, bioactive functionalization led to protoplast enlargement (2D and 2.5D) or plasmolysis (3D). This work shows the potential to modularly engineer synthetic platforms for cellular
