Xanthopinacol Boronate: A Robust, Photochemically Assembled and Cleavable Boronic Ester for Orthogonal Chemistry

open access: yesAngewandte Chemie, EarlyView.
Xanthopinacol (xpin) boronates are a conceptually new class of masked boronic acids designed to alleviate many of the disadvantages of pinacol esters and other popular adducts. They can be formed directly from xanthone and UV light, undergo orthogonal transformations, and are cleavable under photoredox catalysis or oxidative conditions that recycle ...

Biological Control of Agricultural Pests

open access: yesThe American Biology Teacher, 1955
The use of natural enemies to suppress agoricultural pests is called biological control. Its practical value was first demonstrated in California in 1889 in a very spectacular fashion. The citrus industry was then threatened with ruin from the ravages of the destructive cottony cushion scale. This insect was killing the trees and forcing the growers to

Biological pest control and yields depend on spatial and temporal crop cover dynamics

open access: yes, 2015
Summary Modern agricultural landscapes are dynamic systems with interannually changing proportions of different crop types. However, the effects of spatiotemporal changes in crop area on crop yields and crop–herbivore–antagonist interactions have been ...

Fast‐Charging Lithium–Sulfur Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This review explores strategies to overcome fast‐charging challenges in lithium‐sulfur batteries (LSBs). It covers key techniques to address LiPS shuttling, sluggish kinetics, and dendrite formation. The crucial role of battery components, catalysts, and electrode/separator modifications is analyzed.

Reversing Blocking Order of Trithiocarbonate‐Mediated RAFT Polymerizations Using Photocatalysis

open access: yesAngewandte Chemie, EarlyView.
Acrylic‐methacrylic block copolymers have limited accessibility due to monomer order requirements in reversible‐deactivation radical polymerization techniques leading to a vast landscape of block copolymers being understudied. Using unique PET‐RAFT polymerization conditions, a controlled chain extension of poly(methyl acrylate) with methyl methacrylate

Modeling the Integration of Parasitoid, Insecticide, and Transgenic Insecticidal Crop for the Long-Term Control of an Insect Pest [PDF]

open access: yes, 2017
The tools of insect pest management include host plant resistance, biological control, and insecticides and how they are integrated will influence the durability of each.

Utilizing the assassin bug, Pristhesancus plagipennis (Hemiptera: Reduviidae), as a biological control agent within an integrated pest management programme for Helicoverpa spp. (Lepidoptera: Noctuidae) and Creontiades spp. (Hemiptera: Miridae) in cotton [PDF]

open access: yes, 2007
Helicoverpa spp. and mirids, Creontiades spp., have been difficult to control biologically in cotton due to their unpredictable temporal abundance combined with a cropping environment often made hostile by frequent usage of broad spectrum insecticides ...

Enabling High‐Voltage Polymer‐Based Solid‐State Batteries Through Reinforcements with LiAlO2 Fillers

open access: yesAdvanced Energy Materials, EarlyView.
Polymer‐ceramic solid composite electrolytes with passive LiAlO2 fillers show remarkable improvements in Li‐ion conductivity in polycarbonates as compared to both non‐conductive Al2O3 and conductive Li7La3Zr2O12 counterparts. The exceptionally high transference numbers contribute to reversible and stable electrochemistry with Li‐metal electrodes and to

Are agrochemical‐free and biodiversity‐friendly attributes substitutes or complements? Evidence from a coffee choice experiment

open access: yesAgribusiness, EarlyView.
Abstract Eco‐labels inform consumers about the sustainable attributes of a product, but consumer face challenges to differentiate and select for specific attributes. Certification programs are similarly challenged to incentivize adoption of sustainable practices in product supply chains when consumer ability to differentiate sustainable attributes is ...
