Valorization of Yacon (Smallanthus sonchifolius) peel for peroxidase production and its immobilization on alginate beads for 2,4‐dichlorophenol bioconversion

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Sodium alginate was modified with EDC/NHS for the immobilization of Yacon peel peroxidase, resulting in a novel biocatalyst for the oxidation of 2,4‐dichlorophenol. Abstract Yacon (Smallanthus sonchifolius) roots are emerging as an alternative source of peroxidase. This study aimed to extract, immobilize, and characterize the peroxidase from Yacon peel,

Sichere Schülerexperimente mit Iod

open access: yesCHEMKON, EarlyView.
Iod spielt im experimentellen Chemieunterricht eine besondere Rolle, da es im Vergleich zu anderen Halogenen eine geringere akute Toxizität aufweist und als Feststoff gut handhabbar ist. Viele grundlegende Schülerexperimente erfordern daher den Einsatz von Iod. So werden Kupfer(I)‐iodid und Zink (II)‐iodid in der Regel aus festem Iod hergestellt [1, 2].

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

open access: yesEcography, EarlyView.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

open access: yesEcography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Anthropologist, heal thyself: Toward an anthropology of healing through relational interbeing

Drawing on fieldwork with Runa (Quechua) women affected by forced sterilization in Peru and guided by my collaborator and ...
