Metal‐Catalyzed Benzannulation: Recent Advances in Catalyst Design, Mechanistic Insights, and Aromatic Framework Construction

The Chemical Record, EarlyView.
This review offers a contemporary overview of metal‐catalyzed benzannulation (2018–present) encompassing transition, main‐group, post‐transition, and rare‐earth‐metal catalysts. It systematically highlights catalyst design, mechanistic insights, stereo‐ and regioselectivity, and synthetic applications toward aromatic and heteroaromatic scaffolds, while

Synthesis and crystal structure of a complex between lanthanum nitrate and a bicyclic polyether

Inorganica Chimica Acta, 1985
Abstract Reaction between lanthanum nitrate hexahydrate and a macrobicyclic polyether in ethanol has yielded a product of overall stoichiometry 3:2. The ligand, 21R, 26S, 29R, 34S-21, 22, 23, 24, 25, 26, 29, 30, 31,32,33, 34-dodecahydro-1,4,7,14,17,20,28,35-octaoxa (23,29syn218,34syn) (7.7) orthocyclophane, L, provides 8 oxygen donor atoms.

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

High Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

CryoFluorSEM – A new approach for fluorescence and EM imaging of cryofractured plant samples

Journal of Microscopy, EarlyView.
Abstract Cryo‐scanning electron microscopy (CryoSEM) permits the preparation and detailed imaging of bulky samples while keeping them in a hydrated state. For plant biology, cryofractures give information on cell ultrastructure and tissue organisation within a much larger context that is the whole organ or organism.

BvCaM7 Participates in Sugar Beet (Beta vulgaris L.) Resistance to CLS (Cercospora Leaf Spot) by Activating BvPAL via BvMYB108 and Is Accompanied by Calcium Dynamics

Plant, Cell &Environment, EarlyView.
ABSTRACT CLS (Cercospora leaf spot) is a major constraint in sugar beet (Beta vulgaris L.) cultivation, yet the functions of CaM/CML family members in CLS resistance are unclear. This study identified the CaM/CML family in sugar beet and focused on BvCaM7, which was significantly upregulated under CLS. Calcium measurements revealed differential calcium
