Expanding Cyanide‐Bridged Weakly Coordinating Anions Through the Brominated Silver Salt Ag[BCNBBr]

open access: yesChemistry – A European Journal, EarlyView.
The brominated weakly coordinating anion [μ‐(CN)(B(C6F4Br)3)2] ([BCNBBr]−), based on two B(C6F4Br)3 units bridged by cyanide, is obtained as its silver salt Ag[BCNBBr] from CH2Cl2. Ag[BCNBBr] enables oxidation and halide abstraction reactions, affording diverse [BCNBBr]− salts with oxidizing and electrophilic cations.

Influence of Head‐to‐Tail Cyclization of Lanmodulin‐Inspired Peptides on Lanthanide Affinity and Structure

open access: yesChemistry – A European Journal, EarlyView.
The influence of head‐to‐tail cyclization, as well as the effect of ring expansion with an additional glycine on lanmodulin‐inspired peptides on the structure and lanthanide (Ln)‐binding behavior was investigated. While the decrease of structural flexibility can indeed increase the Ln affinity and peptide pre‐organization, it does not lead to an ...

Heterovalent, Homometallic Rings: Synthesis, Optical, and EPR Studies of {TiIV7TiIII} Complexes

open access: yesChemistry – A European Journal, EarlyView.
A new class of heterovalent, homometallic complexes is reported, based on cyclic {TiIV7TiIII} cores with oxide and carboxylate bridges between nearest neighbors. The clusters show Class II mixed‐valent behavior at room temperature, but are valence localized at low temperature.

Carbon monoxide adsorption on NaY zeolite and impregnated with 5% niobium: Characteristics and fixed‐bed study

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Schematic of the CO adsorption process in a fixed‐bed column containing pure NaY zeolite and Nb‐modified NaY (NaY–5%Nb). On the left, breakthrough curves and temperature profiles highlight the dynamic performance and thermal effects during CO adsorption.

Partial identification with categorical data and nonignorable missing outcomes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Nonignorable missing outcomes are common in real‐world datasets and often require strong parametric assumptions to achieve identification. These assumptions can be implausible or untestable, and so we may wish to forgo them in favour of partially identified models that narrow the set of a priori possible values to an identification region.
