Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

Preparation and characterization of thermal neutron sensitive lithium doped polystyrene plastic scintillators

He jishu
BackgroundLithium-doped plastic scintillators possess the dual-mode detection capability for both fast and thermal neutrons, and combine the advantages of conventional plastic scintillators such as cost-effectiveness and the ability to fabricate in large

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

Insect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

New Fluorescent Compounds for Plastic Scintillator Applications Submitted to Nuclear Instruments and Methods New Fluorescent Compounds for Plastic Scintillator Applications [PDF]

, 2020
The fluorescent compound 3-hydroxyflavone (3HF) has been modified in order to study the resulting structure-fluorescence relationship. A series of twelve derivatives, bearing different substituents at various positions on the phenyl ring, has been ...

The plastic scintillator activated with fluorinated 3-hydroxyflavone [PDF]

, 2017
A new radiation-hard plastic scintillator (PS), based on polystyrene and activated with fluorinated 3-hydroxyflavone, is presented. The new scintillator has the light output half-attenuation dose equal to 11 Mrad, which is much more than a similar PS ...

Characteristics of Plastic Scintillators Fabricated by a Polymerization Reaction

Nuclear Engineering and Technology, 2017
Three plastic scintillators of 4.5 cm diameter and 2.5-cm length were fabricated for comparison with commercial plastic scintillators using polymerization of the styrene monomer 2.5-diphenyloxazole (PPO) and 1,4-bis benzene (POPOP).
