Transformative Masked Ortho‐Quinone Chemistry: From Direct Guaiacol Activation to Lignin‐Based Adhesives

open access: yesAngewandte Chemie International Edition, EarlyView.
Renewable guaiacols are rapidly oxidized by phenyliodine(III)diacetate to masked ortho‐quinones, giving a new class of monomers that undergo selective Michael‐type polyaddition with multithiols to from thiol‐guaiacol connectivity‐bearing polymers. The activation applies to discrete monomers and directly to lignin, enabling two‐component adhesives that ...

Mulch Type and Depth, Herbicide Formulation, and Postapplication Irrigation Volume Influence on Control of Common Landscape Weed Species

open access: yesHortTechnology, 2019
Mulch is often applied in landscape planting beds for weed control, but little research has focused specifically on mulch and preemergence (PRE) herbicide combinations.

Mechanical properties of the most common European woods: a literature review

open access: yesFracture and Structural Integrity, 2020
Wood is an orthotropic material used since ancient time. A literature research about the mechanical properties of density, fracture toughness, modulus of elasticity, and Poisson s ratio has been done to have a broader view on the subject.

Second‐Generation Polyhydroxybutyrate Production From Pretreated Corn Lignocellulosic Fraction as a Strategy to Repurpose by Products From the Corn‐Processing Chain

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Lignocellulosic residues are non‐cost, non‐edible, renewable feedstocks that can be used in polyhydroxybutyrate (PHB) production. PHB is a bioplastic synthetized by microorganisms, formed intracellularly under stressful growth conditions; however, its production costs are high, representing the major drawback for fossil‐based plastics ...

Combustion Properties of Timber in Historic Structures: Case Study of the São Pedro de Alcântara Chapel Fire

open access: yesFire and Materials, EarlyView.
ABSTRACT Timber plays a fundamental role in the fire performance of historic building components, where ageing and environmental exposure can markedly influence its physical and chemical properties. This study presents an experimental investigation of the fire behaviour of Ocotea sp.

Comprehensive Review on Advancements in Food Preservation Technologies for Quality and Sustainability

open access: yesFood Chemistry International, EarlyView.
Preservatives limit microbial development, oxidation, and enzymatic degradation, resulting in better food quality and extended shelf life. Classified as natural, synthetic, or biological, each preservative has distinctive attributes and modes of action. Growing preference for natural preservatives aligns with clean label trends.

Survey of Subterranean Termite (Isoptera: Rhinotermitidae) Utilization of Temperate Forests

open access: yesSociobiology, 2014
Both native and invasive subterranean termites (Isoptera: Rhinotermitidae), including the Formosan subterranean termite, are well known pests of urban areas, but little is known about their distribution or impact in forest ecosystems of the southeastern ...

Blackberry Propagation Limitations When Using Floricane Cuttings

open access: yesHortTechnology, 2019
Outdoor production of floricane-fruiting (FF) blackberry (Rubus subgenus Rubus) is problematic in the Northern Great Plains region of the United States because cane injury and plant death will occur from exposure to temperatures −15 °C and colder.

Ringtail (Bassariscus astutus) survival in southwestern Oregon

open access: yesThe Journal of Wildlife Management, EarlyView.
We captured and monitored radio‐collared ringtails over 2 years to estimate monthly and annual survival rates. We found that annual survival rates were much higher within forested landscapes in Oregon than for populations in the southwestern United States.
