Controlling the Decoration of the Reduced Graphene Oxide Surface with Pyrene-Functionalized Gold Nanoparticles [PDF]

open access: yes, 2017
We exploited a non‐covalent approach based on π‐stacking interactions to address the formation of hybrids between pyrene‐functionalized gold nanoparticles (PyAuNPs) and reduced graphene oxide (RGO), in which the former are distributed homogeneously on

Fluoride‐Free Adhesives for Low Surface Energy Fluorinated Substrates

open access: yesAdvanced Functional Materials, EarlyView.
A universal, fluoride‐free adhesive achieves a record 4.91 MPa bond strength on PTFE by leveraging amine/amide dipole–dipole interactions, without fluorinated components. This sustainable strategy overcomes the environmental and performance limits of PFAS‐based adhesives, enabling robust, eco‐conscious bonding across diverse materials.

Investigation of the effects of NaOH dopant level on the physical and mechanical properties of carbon/phenolic composite material [PDF]

open access: yes, 1985
The near-catastrophic erosion of the STS-8A solid rocket booster nozzle was the instigating factor in the recent, and on-going, intensive investigation of carbon/phenolic composite materials.

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 ...

Photothermal Macroporous Lignin Cryogels for Off‐Grid, Continuous Atmospheric Water Collection via Interlayer Heat Recovery

open access: yesAdvanced Functional Materials, EarlyView.
Photothermal, macroporous lignin‐based cryogels are engineered to convert sunlight into low‐grade heat. Integrated as stacked beds in a drum‐type device, a thin copper interlayer transfers waste heat between beds, enabling interlayer heat recovery and continuous solar cycling.

Molecular Weight and Monosaccharide Composition of Astragalus Polysaccharides

open access: yesMolecules, 2008
Two polysaccharides (APS-I and APS-II) were isolated from the water extract of Radix Astragali and purified through ethanol precipitation, deproteination and by ion-exchange and gel-filtration chromatography.

Folding of a donor–acceptor polyrotaxane by using noncovalent bonding interactions [PDF]

open access: yes, 2008
Mechanically interlocked compounds, such as bistable catenanes and bistable rotaxanes, have been used to bring about actuation in nanoelectromechanical systems (NEMS) and molecular electronic devices (MEDs).

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation
