Anti‐Counterfeiting Tags with Camouflaged QR Codes on Nanocavities, Using Polymer‐Dispersed Liquid Crystals

open access: yesAdvanced Materials Technologies, EarlyView.
A QR code, printed through a commercial printer on a thin plastic foil, pre‐coated with a nanocavity is proposed as an anti‐counterfeiting label. Nanocavity imparts distinctive optical properties in terms of light reflection and transmission. A thin layer of polymer‐dispersed liquid crystals (PDLC) is used to camouflage the QR code, that become ...

Interactive soybean variable‐rate seeding simulator for farmers

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3554-3565, November/December 2022., 2022
Abstract Seed expense is a critical component affecting soybean (Glycine max L.) production cost. Achieving potential benefits of adjusting seeding rates by yield environment requires translation from theory to practice through decision support tools.

Constant enzymatic in situ production of H2O2 for an Unspecific Peroxygenase by an L‐amino acid oxidase

open access: yesAdvanced Synthesis &Catalysis, Accepted Article.
Unspecific Peroxygenases have been the subject of a lot of research in the recent past as they offer opportunities for green hydroxylation reactions using hydrogen peroxide (H2O2) as donor. A striking problem of UPOs is their low stability against their own co‐substrate H2O2.

Illuminating the Path of Rearrangement: Visible Light‐Driven Pd‐Catalyzed Substituted Olefins Synthesis

open access: yesAdvanced Synthesis &Catalysis, Accepted Article.
Pd‐catalyzed reactions are among the most straightforward and efficient methods to proficiently build Csp2‐Csp2 bonds. Nevertheless, thermal activation remains mandatory in most cases, which may decrease the compatibility with sensitive functional groups.

Asymmetric synthesis of highly substituted spiro[2H‐pyrrole‐2,3‐succinimide] derivatives by copper‐catalyzed post‐Ugi reactions

open access: yesAdvanced Synthesis &Catalysis, Accepted Article.
Herein we present a novel one‐por methodology for the synthesis of enantioenriched 2H‐pyrrolespirosuccinimides by copper‐catalyzed reactions on Ugi adducts derived from enantiopure α‐alkylbenzyl amines through a chirality transfer process. We have proposed a mechanism supported by density functional theory (DFT) calculations, where a hydrogen radical ...
