Metal (2) 4,4',4",4'" phthalocyanine tetraamines as curing agents for epoxy resins [PDF]
Metal, preferably divalent copper, cobalt or nickel, phthalocyanine tetraamines are used as curing agents for epoxides. The resulting copolymers have high thermal and chemical resistance and are homogeneous. They are useful as binders for laminates, e.g.,

Experimental and Theoretical Confirmation of Covalent Bonding in α‐Pu
From a combination of Reverse Monte Carlo dynamic rigid body fitting to the pair distribution functional and novel density functional approaches, the existence of covalent bonding is confirmed in α‐plutonium alongside other bonding types (i.e. mixed bonding schemes).

The influence of process gas type on the enamel surface condition of a high power diode laser generated single-stage ceramic tile grout seal [PDF]
Almost all laser materials processing operations require the simultaneous use of an process or assist gas. This paper examines the use of O2, Ar, N2 and He as process gasses during the firing of a vitreous enamel to form a single-stage ceramic tile grout

Fully Bio‐Based Epoxy Resins from Liquefied Wood for Chemically Recyclable Wood Coatings
A bio‐based and chemically recyclable epoxy resin derived from liquefied wood and its use in wood coatings is presented. The resin exhibits mechanical, thermal, and water‐resistant properties comparable to commercial coatings and can be chemically recycled and reused. This approach provides fast access to glossy and fully biobased durable wood coatings

Fire Retardancy of Vinyl Ester Nanocomposites: Synergy with Phosphorus-Based Fire Retardants [PDF]
Vinyl ester (PVE) nanocomposites were prepared using both clay and polyhedral oligosilsesquioxanes (POSS) as the nano-dimensional material. From cone calorimetric data, it was shown that both POSS and clay affect the flammability of the nanocomposites to

Efficient Hole Injection From Indium Tin Oxide in Quantum‐Dot Light‐Emitting Diodes
The realization of QLEDs‐based displays remains challenging due to the acidic surface from PEDOT:PSS. Here, an analysis is conducted by examining the degradation mechanism of PEDOT:PSS. By replacing PEDOT:PSS with 2BrCzPA, the formation of strong dipoles at the ITO/2BrCzPA SAM interfaces exhibits excellent hole injection abilities.

A quasi‐2D, light‐absorbing platelet embedded in a thermotropic nematic liquid crystal is activated with light irradiation. Depending on the light intensity, the platelet induces a localized nematic‐isotropic phase transition that triggers the motion. Using different confinements, the platelet can glide in a 2D regime or tilt and glide in a 3D regime ...
