Evolutionary adaptation is facilitated by the presence of lethal genotypes
(American Physical Society, 2024-03)The rate of adaptation in theoretical models of biological evolution generally increases with the mutation rate. However, there is a threshold beyond which mutations into lethal states lead to extinction. It would be logical ... -
Sonocatalytic Activity of Porous Carbonaceous Materials for the Selective Oxidation of 4-Hydroxy-3,5-dimethoxybenzyl Alcohol
(MDPI, 2024-03-23)Selective oxidation, which is crucial in diverse chemical industries, transforms harmful chemicals into valuable compounds. Heterogeneous sonocatalysis, an emerging sustainable approach, urges in-depth exploration. In this ... -
Synthetic strategies for oxidation products from biogenic volatile organic compounds in the atmosphere: A review
(Elseviere, 2023-09-12)Volatile organic compounds (VOCs) emitted by biogenic and anthropogenic sources undergo complex reactions with atmospheric oxidants to generate low-volatility organic species that can form secondary organic aerosols (SOA). ... -
Highly sensitive amperometric sensors based on laccase-mimetic nanozymes for the detection of dopamine
(Royal Society of Chemistry, 2024)The current research presents novel sensors based on laccase-like mimetics for the detection of dopamine (DA). The synthesized laccase-like nanozymes (nAuCu, nPtCu, nCuMnCo, and nCoCuCe) were prepared by a simple hydrothermal ... -
Chromophore hydrolysis and release from photoactivated rhodopsin in native membranes
(National Academy of Sciences USA, 2022-11-02)For sustained vision, photoactivated rhodopsin (Rho*) must undergo hydrolysis and release of all-trans-retinal, producing substrate for the visual cycle and apo-opsin available for regeneration with 11-cis-retinal. The ... -
Surface-enhanced Raman spectroscopy analysis of menstrual cycle: From biochemical changes to diagnostics of vaginal infections
(Science Direct, 2024-06-15)The variability of different processes occurring in a vagina during menstrual cycle can affect the biochemical composition of vaginal fluid. In this study, SERS was adopted to directly track the biochemical changes recorded ... -
Sensitive, Efficient and Portable Analysis of Molecular Exchange Processes by Hyperpolarized Ultrafast NMR
(Wiley-VCH GmbH, 2022-05-02)Molecular exchange processes are ubiquitous in nature. Here, we introduce a method to analyze exchange processes by using low-cost, portable, single-sided NMR instruments. The inherent magnetic field inhomogeneity of the ... -
Redox behaviour of Cu-Aβ(4-16) complexes related to Alzheimer's Disease
(2024)The development of Alzheimer’s Disease (AD) has been linked to abnormal quantities of β-amyloid peptides in the brain. The majority of studies have focussed on Aβ(1-40/42) amyloids and their Cu(II)-Aβ(1-40/42) complexes ... -
Selective (sono)photocatalytic cleavage of lignin-inspired β–O–4 linkages to phenolics by ultrasound derived 1-D titanate nanomaterials
(Elsevier B.V., 2024-03-02)Lignin to value-added aromatic compounds is still an open challenge, since the selective cleavage of the linkages interconnecting the aromatic molecules, especially the β-O-4 ones, is not efficiently achieved yet. Herein, ... -
