A nanoscale investigation of the formation of mesostructured zeolites FAU and LTL (2024)
Journal Article
Zholobenko, V., Hollamby, M., Al-Ani, A., Lebedev, O. I., Smith, A. J., & Snow, T. (2024). A nanoscale investigation of the formation of mesostructured zeolites FAU and LTL. Microporous and Mesoporous Materials, Article 113363. https://doi.org/10.1016/j.micromeso.2024.113363

Nanostructured materials can be utilised as potential catalysts for the production of platform chemicals and renewable biofuels from biomass derived molecules. The formation of hierarchical meso-microporous zeolites LTL and FAU via the surfactant ass... Read More about A nanoscale investigation of the formation of mesostructured zeolites FAU and LTL.

Bifunctional Imine Reductase Cascades for the Synthesis of Saturated N-Heterocycles (2024)
Journal Article
Ramsden, J. I., Zucoloto da Costa, B., Heath, R. S., Marshall, J. R., Derrington, S. R., Mangas-Sanchez, J., …Turner, N. J. (2024). Bifunctional Imine Reductase Cascades for the Synthesis of Saturated N-Heterocycles. ACS catalysis, 14(19), 14703-14710. https://doi.org/10.1021/acscatal.4c03832

Saturated N-heterocycles constitute a vital scaffold for pharmaceutical chemistry but are challenging to access synthetically, particularly asymmetrically. Here, we demonstrate how imine reductases can achieve annulation through tandem inter- and int... Read More about Bifunctional Imine Reductase Cascades for the Synthesis of Saturated N-Heterocycles.

Using Neural Network models to estimate stellar ages from lithium equivalent widths: An EAGLES expansion (2024)
Journal Article
Weaver, G., Jeffries, R. D., & Jackson, R. J. (in press). Using Neural Network models to estimate stellar ages from lithium equivalent widths: An EAGLES expansion. Monthly Notices of the Royal Astronomical Society, https://doi.org/10.1093/mnras/stae2133

We present an Artificial Neural Network (ANN) model of photospheric lithium depletion in cool stars (3000 < Teff/K < 6500), producing estimates and probability distributions of age from 7Li 6708Å equivalent width (LiEW) and effective temperatur...

Benzoylation of Tetrols: A Comparison of Regioselectivity Patterns for O- and S-Glycosides of d-Galactose (2024)
Journal Article
Porter, J., Roberts, J., & Miller, G. J. (in press). Benzoylation of Tetrols: A Comparison of Regioselectivity Patterns for O- and S-Glycosides of d-Galactose. Journal of Organic Chemistry, https://doi.org/10.1021/acs.joc.4c01508

Efficient protecting group strategies are important for glycan synthesis and represent a unique synthetic challenge in differentiating sugar ring hydroxyl groups. Direct methods to enable regioselective protecting group installation are thus desirabl...

HD 21520 b: a warm sub-Neptune transiting a bright G dwarf (2024)
Journal Article
Nies, M., Mireles, I., Bouchy, F., Dragomir, D., Nicholson, B. A., Eisner, N. L., …Ricker, G. R. (in press). HD 21520 b: a warm sub-Neptune transiting a bright G dwarf. Monthly Notices of the Royal Astronomical Society, https://doi.org/10.1093/mnras/stae2079

We report the discovery and validation of HD 21520 b, a transiting planet found with TESS and orbiting a bright G dwarf (V=9.2, Teff = 5871 ± 62 K, R⋆ = 1.04 ± 0.02 R⊙). HD 21520 b was originally alerted as a system (TOI-4320) consisting of two plane... Read More about HD 21520 b: a warm sub-Neptune transiting a bright G dwarf.

Pre-solar grains from novae and "Born-again giants" (2024)
Book Chapter
Evans, A., & Gehrz, R. (2024). Pre-solar grains from novae and "Born-again giants". In Presolar grains in extra-terrestrial materials. Elsevier

We review the properties of dust formed during classical nova eruptions and the Very Late Thermal Pulses (VLTPs) that occur during the later stages of post-Asymptotic Giant Branch evolution of low-mass stars. In both cases, carbon and hydrocarbon dus... Read More about Pre-solar grains from novae and "Born-again giants".

Structural and ion exchange study of nanostructured materials (2024)
Thesis
Contini, A. (2024). Structural and ion exchange study of nanostructured materials. (Thesis). Keele University. Retrieved from https://keele-repository.worktribe.com/output/857282

In this thesis, the structural and acidic properties of two zeolites LTL and MAZ are compared and reported. Commercial LTL and MAZ were ion exchanged with metal alkali cations, to obtain the corresponding ion exchanged forms, and characterised by IR...

V454 Aur is an eclipsing binary system containing two solar- type stars on an orbit of relatively long period (P P = 2702 d) and large eccentricity (e e = 0381). Eclipses were detected using data from the Hipparcos satellite, and a high-quality doubl... Read More about Rediscussion of eclipsing binaries. Paper XIX.
