Vesicular Membrane with Structured Interstitial Water Self-assembled vesicles with structured (tetrahedral order with strong hydrogen bonds) interstitial water are reported. The vesicles, known as MCsome, are assembled from metal carbonyl compounds, FpR ...

Water isn’t just a solvent. It builds structure. Our study reveals vesicle membranes stabilized by highly ordered, hydrogen-bonded interstitial water. A new route to designing functional soft materials where water actively controls stability.

A question is whether we can replace basil with other leaves and get the same <Leaf>-Fe_{3}O_{4} NP ?? 🤔

Arctic sea ice hits lowest winter level as unprecedented heat hits smashes records all over Earth Arctic sea ice has shrunk to a tie for its lowest winter peak on record

Arctic sea ice hits record-low winter peak (~5.52M sq mi), as global heat extremes shatter records.

Loss of reflective (high-albedo) sea ice accelerates warming via ocean heat uptake, signalling cryosphere instability, not normal seasonal variability.

very interesting. Would be glad to measure their Raman !

very interesting !

Thank you !

very cool !

Great post and comments ! The core principle of science is constant correction and acceptance that something is not fully explored or correlated with the available data.

Hypothesis is built to be discarded/changed/refined/retested with new experiments.

Includes a large dataset on dipole polarizabilities for 12 diatomics, with their anharmonic and harmonic rovibrational wavefunctions.

Testing the limitations of harmonic approximation in the determination of Raman intensities Raman intensities in molecular spectra are usually computed within double harmonic approximation. This procedure relies on treating a vibrating molecule as a collection of harmonic oscillators and ...

🧪How accurate is the harmonic approximation in Raman intensity calculations? Tested on 12 diatomics using exact anharmonic wavefunctions and distance-dependent polarizabilities. Errors go as high as 10% with F₂ showing the largest deviation.

Posthandling Spectral Information Enhancement for Single Cell Raman Molecular Mapping Analysis Biochemical analysis of living systems such as single cells benefits greatly from the label-free and low-invasive molecular mapping with Raman microspectroscopy. Sets of Raman spectra at different spatial points are analyzed to generate Raman molecular maps corresponding to specific chemical species. However, human error and subjective data analysis can be technical issues that limit interpretation and its validity. Here, we present an objective data analysis scheme for postprocessing large data sets of Raman spectra for molecular mapping of living cells. The process comprises three steps: (i) Denoising the spectral data set using low-rank approximation; (ii) obtaining an objective background from data points outside the target cell; (iii) subtracting the thus obtained background using Hypothetical Addition Multivariate Analysis with Numerical Differentiation (HAMAND) via an automatically determined coefficient. Through the present analysis, minor Raman peaks, as indiscernible as they are, can be identified and precisely mapped. We demonstrate a quantitative discussion of cellular components after extracting contributions only from a single target cell from a Raman mapping image where multiple cells or parts of other cells are present. This work opens an improved analysis workflow for accurate spectroscopic analysis of living cells with the advantage of identifying minor Raman peaks unambiguously.

By refining how we process Raman information, the study transforms every cell from a blur of chemistry into a clearly textured molecular landscape.
