Balancing Chain Transfer Agent Transport and Reaction in Emulsion Polymerization

Macromolecular Reaction Engineering, EarlyView.
The interrelationship between chain transfer agent mass transfer and reaction in emulsion polymerization is examined. Three parameters describing these phenomena are proposed. The probability of mass transfer‐ rather than reaction‐limitation for each CTA‐monomer pair is assessed.

Optimizing Ex Vivo MRI and Controlling the Roll of the Specimen Using Container‐ and Brain‐Specific 3D‐Printed Holders

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Positioning and stabilizing a specimen in a container in preparation for ex vivo MRI are challenging. In addition, ex vivo MRI is often performed using preclinical scanners with gradient nonlinearity and nonhomogeneous sensitivity, requiring optimal placement.

Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

The Effect of the Aging Process of Polyamide 11 Used in Flexible Pipelines and Its Influence on the Permeability of Carbon Dioxide

Polymer Engineering &Science, EarlyView.
Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...

Reducing copper inputs through integration of essential oil‐based formulations: laboratory and 2‐year vineyard evaluation against Plasmopara viticola

Pest Management Science, EarlyView.
Combining an essential oil (EO)‐based formulation with copper effectively controls Plasmopara viticola. Field trials showed a 92–99% protection with lower copper inputs, achieving a 45% copper reduction without compromising efficacy. This approach supports EO‐based products as sustainable alternatives for grapevine downy mildew management.

University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.

Dumpsite Seabed Characterization of the San Pedro Basin, CA, From Autonomous Vehicle Observations

Journal of Field Robotics, EarlyView.
ABSTRACT A wide‐area seabed survey was conducted using autonomous underwater vehicles (AUVs) in a known dumpsite off the coast of Southern California that has been found to have widespread sediment contamination from the chemical dichlorodiphenyltrichloroethane (DDT).
