Cambridge structural database (CSD) [PDF]

open access: yes, 2011
Department of Chemistry, University of Belgrade, Serbia Cambridge Structural Database (CSD) contains more than five hundred thousand crystal structures of small molecules. Around 150 new crystal structures are archived every day. The data archived in the CSD can help in various fields of research. Some of them are crystallography, structural chemistry,

Cognitive Status in People With Epilepsy in the Republic of Guinea: A Prospective, Case–Control Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with epilepsy (PWE) may experience cognitive deficits but fail to undergo formal evaluation. This study compares cognitive status between PWE and healthy controls in the West African Republic of Guinea. Methods A cross‐sectional, case–control study was conducted in sequential recruitment phases (July 2024–July 2025) at Ignace ...

How Do the Surroundings of the C-NO2 Fragment Affect the Mechanical Sensitivity of Trinitroaromatic Molecules? Evidence from Crystal Structures and Ab Initio Calculations

open access: yesCrystals
The dissociation of the C-NO2 bond is the initial step in the process of the detonation of nitroaromatic explosives. The strength of the C-NO2 bond is significantly influenced by the relative position of the nitro group with respect to the aromatic ring ...

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

Close-packing transitions in clusters of Lennard-Jones spheres [PDF]

open access: yes, 2005
The structures of clusters of spherical and homogeneous particles are investigated using a combination of global optimization methods. The pairwise potential between particles is integrated exactly from elementary Lennard-Jones interactions, and the use ...

Automated oxidation-state assignment for metal sites in coordination complexes in the Cambridge Structural Database.

open access: yesActa Crystallographica. Section B: Structural Science, Crystal Engineering and Materials, 2019
The Cambridge Structural Database (CSD) currently contains over 400 000 transition-metal-containing entries, however many entries still lack curated oxidation-state assignments.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

The prediction of single-molecule magnet properties via deep learning

open access: yesIUCrJ
This paper uses deep learning to present a proof-of-concept for data-driven chemistry in single-molecule magnets (SMMs). Previous discussions within SMM research have proposed links between molecular structures (crystal structures) and single-molecule ...

Structural Classification of Metal Complexes with Three-Coordinate Centres [PDF]

open access: yes, 2015
Attempts to describe the geometry about three-coordinate silver(I) complexes have proven difficult because interatomic angles generally vary wildly and there is no adequate or readily available classification system found in the literature.
