Molecular Weight–Dependent Reinforcement of Biobased Aromatic Thermoplastic Polyurethanes Using Vegetable Oil Crosslinkers

Polymer Engineering &Science, EarlyView.
Strategy for biobased aromatic thermoplastic polyurethanes. ABSTRACT The transition toward sustainable thermoplastic polyurethanes (TPUs) is a key challenge for reducing the carbon footprint for a wide range of applications, from industrial to transportation, including advanced applications such as 3D‐printed sensors and soft actuators.

Photochromic carbazole photoinitiators for precision visible‐light photopolymerization

Polymer International, EarlyView.
New carbazole–naphthopyran derivatives were employed as visible‐light‐activated photoinitiators, enabling rapid and localized radical photopolymerization to produce well‐defined thin solid objects within minutes. Abstract Two carbazole derivatives, each incorporating a naphthopyran unit and an aromatic ketone, were synthesized and evaluated as ...

Assessment of the Interaction between Ammonium Dinitramide and Isocyanurate Bonding Agents for Application on Technologies of Composite Solid Propellants

Propellants, Explosives, Pyrotechnics, EarlyView.
This work investigates the interaction of two isocyanurate‐based bonding agents with ammonium dinitramide: triallyl isocyanurate and 1,3,5‐tris(2‐hydroxyethyl) isocyanurate, which contain alkene and hydroxyl functional groups in their side chains, respectively.

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

Pest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.
