Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane

Journal of Polymer Science, EarlyView.
Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...

Soil‐dependent variation in strigolactone signaling distance revealed by a parasitic seed germination bioassay

Pest Management Science, EarlyView.
A parasitic seed germination bioassay reveals strong soil‐dependent variation in strigolactone signaling distance, controlled by physical and biological soil properties, which shapes signaling range and parasitic weed infection risk. Abstract BACKGROUND Strigolactones are root‐exuded plant metabolites acting as germination stimulants for several ...

Dual‐Component Spidroin‐Based Hydrogels: A Mechanically Tunable Platform for 2D and 3D Cell Culture

Small, EarlyView.
A dual‐component recombinant spider silk hydrogel platform was developed by combining NT2RepCT with a bioactive vitronectin‐functionalized spidroin domain. The hydrogels self‐assemble under physiological conditions, exhibit tunable mechanical properties, and support 2D and 3D cell culture, providing a versatile platform for mechanobiological studies ...

The Chemical Effects of Nitrogenous Substances in Two Different Grades of PVDF Used in Offshore Applications

Journal of Vinyl and Additive Technology, EarlyView.
Proposed reaction schematic. ABSTRACT In this work, two different grades of poly(vinylidene fluoride) (PVDF) commonly used in offshore applications, one with 3% of dibutyl sebacate (DBS) plasticizer and the other a copolymer containing chlorotrifluoroethylene (CTFE), were subjected to an aging process in contact with a fluid containing hydrocarbons ...

The Early Upper Palaeolithic in British caves: problems and potential Le Paléolithique supérieur ancien dans les grottes de Grande‐Bretagne : problèmes et potentiels

Journal of the Royal Anthropological Institute, EarlyView.
Recent years have seen landmark progress in our understanding of early Homo sapiens occupation of Europe, owing to new excavations and the application of new analytical methods. Research on British sites, however, continues to lag. This is because of limitations inherent in existing cave collections, and limited options for new fieldwork at known sites.

Pinnipeds in New York (1996–2021) are stranding less frequently but human interaction cases are increasing

NAMMCO Scientific Publications
Every year pinnipeds from five different species—gray (Halichoerus grypus), harbour (Phoca vitulina), harp (Pagophilus groenlandicus), hooded (Cystophora cristata), and ringed (Pusa hispida) seals—haul out on New York’s beaches.

125 years of exploration and research at Gough's Cave (Somerset, UK) 125 ans d'exploration et de recherches à Gough's Cave (Somerset, Royaume‐Uni)

Journal of the Royal Anthropological Institute, EarlyView.
Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

Is Cone‐Beam CT Reliable for Apical Foramen Assessment? A Micro‐CT–Referenced Study

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the diagnostic accuracy of two cone‐beam CT (CBCT) dose protocols for identifying the number and trajectory deviation of apical foramina. Forty lower molars were scanned in Micro‐CT. Thereafter, all teeth were inserted into the mandible sockets and a titanium implant and an endodontically treated tooth with a cobalt ...
