Virus-Mediated Self-Assembly of Functional Cyclodextrins for Antiviral Inhibition. [PDF]

open access: yesAngew Chem Int Ed Engl
A sialic acid (SA)‐functionalized cyclodextrin (CD) self‐assembles on SARS‐CoV‐2 through ligand–receptor recognition, nucleating cooperative supramolecular polymer growth that blocks infection. The adaptive assembly requires both ligand binding and host–guest polymerization, remains active across variants, and can be tuned by coassembly, establishing ...

Tuning the Length of Filomicelles Prepared Via Templated Polymerization-Induced Self-Assembly. [PDF]

open access: yesSmall
High‐aspect‐ratio polymeric micelles are attractive yet notoriously difficult to control in length. We reveal a counterintuitive and powerful solution: in supramolecularly templated PISA, adding non‐sticker polymer unexpectedly elongates the micelles, while post‐assembly sonication enables precise shortening with reduced dispersity.

Exploring Volatile Precursors: Synthesis, Characterization and Thermal Properties of Thulium Fluoroacetylacetonate Complexes

open access: yesCrystals, 2023
Five trifluoroacetylacetonate (tfaa−) complexes [Tm(tfaa)3(H2O)]2, [Tm(tfaa)3(H2O)2], [Tm(tfaa)3(H2O)2] · diglyme, [Tm(tfaa)3(DME)] (DME = 1,2-dimethoxyethane) and [TmCl2(tfaa)(diglyme)] (diglyme = bis(2-methoxyethyl) ether) of thulium have been ...

Investigating crystal orientation patterns of foraminiferal tests by electron backscatter diffraction analysis [PDF]

open access: yesEuropean Journal of Mineralogy, 2020
We studied the crystallographic orientation of calcite crystals in benthic foraminifers by electron backscatter diffraction (EBSD). Individuals of two species, Gyroidinoides soldanii and Cibicidoides grimsdalei, featuring different test structures, were ...

Adaptation of Microbialite-Associated Prokaryotic Communities to Natural and Experimental Anoxic Conditions. [PDF]

open access: yesGeobiology
ABSTRACT Microbialites are rocks formed by microbial communities that influence, promote, and/or control the precipitation of mineral phases. The oldest microbialites date back to the Archean and formed under globally anoxic conditions. Accordingly, modern microbialites developing under oxic conditions are limited analogs of their earliest predecessors.

Mineralogical Controls on the Ti Isotope Composition of Subduction Zone Magmas

open access: yesGeochemistry, Geophysics, Geosystems, 2023
The positive Ti isotope versus SiO2‐content correlation in igneous rocks reflects the fractional crystallization of Ti‐bearing oxide minerals. However, Ti isotope variations of subduction‐related igneous rocks indicate that the Ti isotope compositions of

Trace element partitioning between pyrochlore, microlite, fersmite and silicate melts

open access: yesGeochemical Transactions, 2020
We present experimentally determined trace element partition coefficients (D) between pyrochlore-group minerals (Ca2(Nb,Ta)2O6(O,F)), Ca fersmite (CaNb2O6), and silicate melts.

U mobilization and associated U isotope fractionation by sulfur-oxidizing bacteria

open access: yesFrontiers in Microbiology, 2023
Uranium (U) contamination of the environment causes high risk to health, demanding for effective and sustainable remediation. Bioremediation via microbial reduction of soluble U(VI) is generating high fractions (>50%) of insoluble non-crystalline U(IV)
