Insecticides outweigh rye cover crop in triggering secondary pest outbreaks

Pest Management Science, EarlyView.
Insecticides outweigh rye cover crop in triggering secondary pest outbreaks. Zeus Mateos‐Fierro*, Ashley Leach, Ian Kaplan. Spider mite and melon aphid outbreaks are enhanced with broad‐spectrum insecticides, while natural enemies are reduced. However, rye cover crop has little effect on either pest or natural enemy populations.

On‐Tip Polymerization Method for Multimodal Characterization of Nanoparticles with Electron/Ion Imaging and Atom Probe Tomography

Small Methods, EarlyView.
This study presents an on‐tip polymerization method that employs a needle substrate with a designed through‐microchannel (“needle‐eye”) to retain a picoliter‐scale solution of nanoparticles. Using a resin precursor as the solution, polymerization is carried out in situ at the needle tip.

Biocarbon Suitability Evaluation for Direct Injection in Blast Furnace Ironmaking

steel research international, EarlyView.
This study examines densified biocarbon for direct injection in blast furnace ironmaking to reduce greenhouse gas (GHG). Enhanced burnout performance, along with favorable reactivity and carbon structure of the combustion residue, supports its suitability for blast furnace injection. Modeling results indicate that up to a 27% reduction in GHG emissions

Long‐term mechanical properties of hybrid fiber‐reinforced engineered cementitious composite

Structural Concrete, EarlyView.
Abstract Hybrid fiber‐reinforced engineered cementitious composites (hybrid ECC) employing short straight polyethylene (PE) and steel fibers have attracted growing interest in engineering applications due to their superior strength and ductility. In most studies, the mechanical properties of hybrid ECC were determined based on samples cured for 28 days,
