Bioinspired Ether Cyclizations within a π-Basic Capsule Compared to Autocatalysis on π-Acidic Surfaces and Pnictogen-Bonding Catalysts. [PDF]

Chemistry, 2021
Breaking the rules: Thanks to their broad responsiveness, epoxide‐opening ether cyclizations are identified as ideal for the direct comparison of supramolecular catalysts. The results suggest that π‐basic supramolecular capsule catalysts are as outstanding as pnictogen‐bonding catalysts in breaking the Baldwin rules with high diastereoselectivity ...

Electric-Field Catalysis on Carbon Nanotubes in Electromicrofluidic Reactors: Monoterpene Cyclizations. [PDF]

Angew Chem Int Ed Engl
Studies on the cyclization of monoterpenes on carbon nanotubes in electromicrofluidic devices support that electric‐field catalysis under scalable bulk conditions can stabilize both anionic and cationic transition states, can provide access to reactions general Brønsted acid, Lewis acid, anion‐π and cation‐π catalysts do not to really catalyze, and ...

Pbx loss in cranial neural crest, unlike in epithelium, results in cleft palate only and a broader midface. [PDF]

J Anat, 2018
Abstract Orofacial clefting represents the most common craniofacial birth defect. Cleft lip with or without cleft palate (CL/P) is genetically distinct from cleft palate only (CPO). Numerous transcription factors (TFs) regulate normal development of the midface, comprising the premaxilla, maxilla and palatine bones, through control of basic cellular ...

Evolution of the neuronal substrate for kin recognition in social Hymenoptera

Biological Reviews, Volume 98, Issue 6, Page 2226-2242, December 2023., 2023
ABSTRACT In evolutionary terms, life is about reproduction. Yet, in some species, individuals forgo their own reproduction to support the reproductive efforts of others. Social insect colonies for example, can contain up to a million workers that actively cooperate in tasks such as foraging, brood care and nest defence, but do not produce offspring. In

Value chain research and development: The quest for impact

Development Policy Review, Volume 41, Issue 5, September 2023., 2023
Summary Motivation For decades, governments, donors, and practitioners have promoted market‐based development approaches (MBDA), most recently in the form of value chain development (VCD), to spur economic growth and reduce poverty. Changes in approaches have been shaped by funders, practitioners and researchers in ways that are incompletely ...

“Genes for a role,” “genes as essences”: Secondary students' explicit and implicit intuitions about genetic essentialism and teleology

Journal of Research in Science Teaching, Volume 60, Issue 2, Page 237-267, February 2023., 2023
Abstract Biology education research has shown that deeply rooted intuitions can influence students' understanding of biological phenomena. One example is design teleology, the intuition that organisms' traits were designed to fulfill a goal. Another example is psychological essentialism, the intuition that organisms have fixed essences.

Teflon Magnetic Stirring Capsules (TMSC) as a Practical and Reusable Delivery System for Sensitive Reagents and Catalysts

Helvetica Chimica Acta, Volume 104, Issue 9, September 2021., 2021
Abstract The development of a user‐friendly reusable laboratory equipment for the delivery of sensitive reagents and catalysts is described. The tightness of these Teflon Magnetic Stirring Capsules (TMSC) is ensured by the magnetic force and release of the reagent inside the solution is triggered by adjusting the stirring rate so that the centrifuge ...

PENSÉE DU RÉEL ET DOUBLES IMPENSABLES DANS LA PHILOSOPHIE DE CLÉMENT ROSSET

Revista Trágica, 2019
La pensée du réel de Clément Rosset, et ses rapports compliqués avec le double fantasmatique dont la critique est le corrélat essentiel, a souvent prêté à confusion.
