Photooxidation of 18‐Carbon Polyunsaturated Fatty Acids to Prepare Mono‐Hydroxylated Octadecanoids

open access: yesLipids, EarlyView.
We developed a fast and simple one‐step synthetic strategy to produce mono‐hydroxylated metabolites based on the photosensitized oxidation of 18‐carbon polyunsaturated fatty acids (PUFAs). This approach could likely be extended to other PUFAs, suggesting that photosensitized oxidation could be employed to rapidly prepare hydroperoxides from multiple ...

Numerical simulation of a centrifuge test related to the interaction between an ice feature and an offshore pipeline

open access: yes, 2007
Ice features present one of the major obstacles to offshore development in the Arctic and Atlantic regions of Canada. Ice features have been observed to interact with the see floor creating scour features (Clark et al., 1986).

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

open access: yesLaser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Arsonic Acid Functional Polymers Enable Stabilization of Iron Oxide Nanoparticles in Aqueous Solution

open access: yesMacromolecular Rapid Communications, EarlyView.
Arsonic acid containing diblock copolymers are developed to incorporate arsonic acid moieties for surface anchoring to IONPs, along with water soluble PEG blocks to impart colloidal stability in aqueous environments. The resulting polymer‐coated IONPs are evaluated for stability in physiological media and cytocompatibility.

The flexural behaviour of ice from in situ cantilever beam tests

open access: yes, 1978
The cantilever beam test has been used very extensively in both the field and laboratory to investigate the flexural strength and strain modulus of sea ice.

Ice-Structure Interaction Analysis: Inverse Ice Force Prediction for Stiffened Plate and Dynamic Simulation [PDF]

open access: yes, 2018
Offshore regions of the Arctic and the Great Lakes hold valuable resources in many respects for harvesting energy and serving as important shipping lanes.

Masterbatch‐Assisted Fabrication of Polylactic Acid/Reduced Graphene Oxide Nanocomposites Exhibiting Mechanical Enhancement and UV‐C Aging Resistance

open access: yesPolymer Composites, EarlyView.
Masterbatch‐Assisted Fabrication of Polylactic Acid/Reduced Graphene Oxide Nanocomposites. ABSTRACT Polylactic acid (PLA) is a promising bio‐based polymer; nonetheless, its extensive application is still limited by poor fracture toughness, low thermal stability, and strong susceptibility to degradation induced by ultraviolet (UV) radiation.

Partially prestressed concrete internal square panel [PDF]

open access: yes, 1986
This work is concerned with the general behaviour of an internal panel in a column supported multi-bay floor structure, under the influence of various prestressing tendon arrangements.

A Review of Mechanical Reinforcement and Piezoresistive Self‐Sensing in Carbon Nanotube Fiber Composites

open access: yesPolymer Composites, EarlyView.
PSPP‐TRL mapping of CNT‐modified CFRP literature, with four recurring confusions resolved and five scale‐up problems quantified. ABSTRACT Carbon nanotube‐modified fiber composites are often presented as a route to stronger, tougher, and self‐sensing structural materials.
