Valence and Site Engineering Enable Efficient Broadband Near‐Infrared Emission at 960 nm in Cr3+‐Activated Forsterite

open access: yesAdvanced Materials, EarlyView.
This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...

Acetylene terminated matrix resins [PDF]

open access: yes, 1985
The synthesis of resins with terminal acetylene groups has provided a promising technology to yield high performance structural materials. Because these resins cure through an addition reaction, no volatile by-products are produced during the processing.

A Study on Tensile Behavior and Water Uptake of Wood Powder-Composites Based on Epoxy and Unsaturated Polyester Resins [PDF]

open access: yesIranian Journal of Wood and Paper Industries, 2013
In this study, two kinds of epoxy resins (i.e. high-viscosity and low-viscosity) as well as one polyester resin (orthophthalic grade) were selected and examined as pure resins and also as a polymeric matrix for producing wood-composites.

Epoxy resins produce improved plastic scintillators [PDF]

open access: yes, 1967
Plastic scintillator produced by the substitution of epoxy resins for the commonly used polystyrene is easy to cast, stable at room temperature, and has the desirable properties of a thermoset or cross-linked system.

Durable Low‐Interfacial Toughness PDMS/SiO2 Coatings with Superior Anti‐Icing and Large‐Scale Deicing Performance in the Natural Field

open access: yesAdvanced Materials Interfaces, EarlyView.
Low‐interfacial toughness PDMS/SiO2 coatings are applied to aluminum substrates and tested under natural high‐altitude conditions. The coatings demonstrate strong anti‐icing, icephobic, and large‐scale deicing performance. Field results highlight delayed freezing, reduced ice adhesion, and stable durability, offering practical insights into the use of ...

Rapid microwave processing of epoxy nanocomposites using carbon nanotubes [PDF]

open access: yes, 2013
Microwave processing is one of the rapid processing techniques for manufacturing nanocomposites. There is very little work focussing on the addition of CNTs for shortening the curing time of epoxy nanocomposites. Using microwave energy, the effect of CNT
