Removal of Heavy Metals from Aqueous Solution using Clinoptilolite and Stilbite [PDF]

open access: yes, 2014
Heavy metals are highly toxic and they must be removed from the polluted streams. Аdsorption by zeolites is currently considered to be very suitable for wastewater treatment because of its simplicity and cost effectiveness.

Interfacial Electric Field Engineering of High‐Entropy Heterostructures Triggering Self‐Limiting Reconstruction for Industrial‐Scale Electrocatalysis

open access: yesAdvanced Science, EarlyView.
An interfacial electric field engineering strategy is proposed to trigger the self‐limiting surface reconstruction of high‐entropy heterostructures. Driven by this built‐in field, the controlled sacrificial leaching of W evolves a robust active layer, enabling exceptional oxygen evolution performance and ultrastability at ampere‐level current densities

Switching Spike Plasticity Shapes ACE2 Engagement Across SARS‐CoV‐2 Variants

open access: yesAdvanced Science, EarlyView.
Conformational plasticity governs SARS‐CoV‐2 spike function and ACE2 recognition. Using high‐speed AFM and single‐molecule force spectroscopy, we analyzed the ancestral spike and nine variants, revealing progressive rigidification from Delta, variable plasticity in Omicron sublineages, and JN.1 compaction.

Rapid Exonuclease‐Based De Novo Sequencing Strategy for Long Oligonucleotides via Liquid‐Phase Ion Trap Coupled With Mass Spectrometry

open access: yesAdvanced Science, EarlyView.
A liquid‐phase ion trap (LPIT) coupled with ESI‐MS enables rapid, high‐fidelity de novo sequencing of long oligonucleotides in ∼30 min. By applying an electric field to dissociate metal adducts in solution, LPIT delivers clean spectra, superior mass accuracy, and full sequence coverage, surpassing MALDI‐TOF and LC‐MS.
