Vibrational assignments of cyclic dimers and inter-monomers of adenine relating FT-IR, FT-Raman and UV spectra with SQMFF and DFT calculations [PDF]

In this work, three different cyclic dimers and a tetramer of adenine taken from the experimental structure determined by X-ray diffraction have been studied by combination of experimental FT-IR, FT-Raman and UV–Visible spectra with hybrid B3LYP/6–311++G*

Season and human footprint weaken the negative effect of temperature on the intraspecific metabolic scaling exponent of wild brown trout populations

Journal of Animal Ecology, EarlyView.
We apply a new parameterized model through linking metabolic scaling and the maximum entropy theory of ecology to quantify the intraspecific metabolic scaling exponent of brown trout populations and assess the main drivers shaping the exponent. Abstract Metabolic scaling fundamentally sets the pace of life in almost all organisms.

Whole genome sequencing of historical specimens from the world's largest fungal collection yields high‐quality assemblies

New Phytologist, EarlyView.
Summary High‐throughput molecular studies of museum specimens (museomics) have great potential in biodiversity research, but fungal historical collections have scarcely been examined, leading to no comprehensive methodological assessments. Here we present a whole genome sequencing (WGS) project conducted at the Fungarium of the Royal Botanic Gardens ...

Deepening on the Intercalation Pseudocapacitive Behavior of Ti0.33Nb0.66O2 Rutile as the Anode Material for Lithium‐Ion Batteries

ChemElectroChem, Volume 13, Issue 9, 5 May 2026.
This study shows that the beneficial effect of Nb by Ti partial substitution on TiO2 consists of a significant increase in the lithium diffusion coefficient, resulting from the opening of structural tunnels. This explains the intercalation pseudocapacitive behavior of Nb‐derivatives of TiO2. The electrochemical performance of a rutile with high niobium

Computational Design of Azole Derivatives as Multifunctional Agents for Alzheimer's Disease

Applied Organometallic Chemistry, Volume 40, Issue 5, May 2026.
A series of 19 azole derivatives were evaluated using bioinformatic tools and density functional theory in the context of multifunctional agents for Alzheimer's disease and were classified as potential antioxidant, distributor, and suppressor agents. ABSTRACT Alzheimer's disease (AD) is the most common form of dementia, characterized by multifactorial ...
