Synthesis of uniform core‐shell calcium hydroxide‐calcium carbonate biocidal particles via encapsulation into dry ice

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Synthesis of core‐shell calcium hydroxide‐calcium carbonate biocidal particles via encapsulation into dry ice. Abstract This study introduces a novel synthesis method for core‐shell calcium hydroxide‐calcium carbonate (CSCC) biocidal particles by inducing a phase change in liquid CO2$$ {\mathrm{CO}}_2 $$, thereby coating CaOH2$$ \mathrm{Ca}{\left ...

White matter microstructure and longitudinal relaxation time anisotropy in human brain at 3 and 7 T

open access: yesNMR in Biomedicine, Volume 36, Issue 1, January 2023., 2023
White matter (WM) with high structural anisotropy T1 shows angular dependency on B0. At 3T, a T1 peak at 54° and flat baseline across 0° and 90° are observed in WM [Panel A, T1 as a function of fibre‐to‐filed angle (q)]. At 7T, the T1 peak is centred at 40°.

Weighing risks against GHG reduction benefits in emerging green technologies

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Green technologies represent promising strategies for mitigating carbon emissions and combating global warming. However, their implementation in civil and industrial applications is not without risks, as intrinsic uncertainties and latent safety concerns can threaten their effective deployment.

Fast, interleaved, Look‐Locker–based T1 mapping with a variable averaging approach: Towards temperature mapping at low magnetic field

open access: yesNMR in Biomedicine, Volume 36, Issue 1, January 2023., 2023
Through the proposed Look‐Locker–based T1 mapping sequence, temperature maps of homogeneous doped‐water solutions at 0.1 T could be obtained in 10 min. The use of a variable averaging scheme enhanced T1 estimation accuracy, leading to a temperature precision of 3.0 ± 1.1°C and an accuracy of 1.5 ± 1.0°C.

Structural Insights Into Galectin‐3 Recognition of a Selenoglycomimetic

open access: yesChemMedChem, EarlyView.
Galectin‐3, a β‐galactoside‐binding protein, plays a pivotal role in fibrosis and carcinogenesis. We explore the molecular recognition of a seleno‐digalactoside, modified with a benzyl group (SeDG‐Bn), as a potent Gal‐3 inhibitor. Using nuclear magnetic resonance and molecular dynamics simulations, we present a 3D model of the SeDG‐Bn/Gal‐3 complex ...

High‐field ex vivo and in vivo two‐dimensional nuclear magnetic resonance spectroscopy in murine brain: Resolving and exploring the molecular environment

open access: yesNMR in Biomedicine, Volume 36, Issue 2, February 2023., 2023
The molecular environment in the murine brain was explored both in and ex vivo at high (14.1‐ and 15.2‐T) fields, using homonuclear and heteronuclear 2D NMR techniques. These revealed approximately 10 and 29 metabolites, respectively, and led to the assignment of 137 cross‐peaks in total.

New methods for robust continuous wave T1ρ relaxation preparation

open access: yesNMR in Biomedicine, Volume 36, Issue 2, February 2023., 2023
New and existing state‐of‐the‐art CW‐T1ρ schemes were compared theoretically, numerically, and experimentally at 9.4 T. Of the CW‐T1ρ methods using hard pulses, the proposed triple‐focus and earlier single‐refocus methods were highly robust, while the scheme using adiabatic excitation and double refocusing with BIR‐4 was the most robust. Measurement of

N‐Heterocyclic Carbenes: A Benchmark Study on their Singlet–Triplet Energy Gap as a Critical Molecular Descriptor

open access: yesChemPhysChem, EarlyView.
The adiabatic singlet–triplet gap is proposed as a critical and sensitive descriptor for understanding the nature and diversity of N‐heterocyclic carbenes. This approach facilitates the rationalization of experimental and computational trends. High‐level electronic structure calculations (multiconfigurational and coupled cluster) strongly support this ...

The impact of optical excitation on the binding in complexes of the cationic gold dimer: Au2+N2${\rm{Au}_{2}^{+}} {\rm{N}_{2}} $ and Au2+N2O${\rm{Au}_{2}^{+}} {\rm{N}_{2}{\rm{O}}} $

open access: yesNatural Sciences, Volume 3, Issue 1, January 2023., 2023
Vibrationally‐resolved optical spectra of Au2+N2${\rm{Au}_{2}^{+}} {\rm{N}_{2}} $ and Au2+N2O${\rm{Au}_{2}^{+}} {\rm{N}_{2}{\rm{O}}} $ allow for a detailed look at the binding motifs in the ground and excited states of these important metal complexes, opening the door for a systematic approach in the study of their reactivity.
