Cobalt Single‐Atom Catalysts for Ultrafast Sulfamethoxazole Degradation: Unveiling the Chloride‐Ion‐Enhanced Formation of Co(IV)=O

open access: yesAdvanced Science, EarlyView.
An atomically dispersed Co–N4 single‐atom catalyst rapidly activates peroxymonosulfate to remove the antibiotic sulfamethoxazole from water. Common ions have little impact, but chloride dramatically speeds degradation by promoting a high‐valent Co(IV) = O oxidant via in situ HOCl–catalyst electron transfer.

Speciation patterns in predominately self-pollinated Mediterranean annuals

open access: yes, 1997
Many groups of annual plants in the Mediterranean basin are characterized by self-pollination. It is suggested that the breeding system operating in these plants affected considerably their mode of speciation. It is argued that the reproductive isolation

Rational Design of Weakly‐Solvating Molecules for Salt‐In‐Pre‐Ionic‐Liquid Electrolytes for Li Metal Batteries

open access: yesAdvanced Science, EarlyView.
The weakly‐solvating TFMSPyr electrolyte tailors the Li+ solvation structure by suppressing solvent coordination and promoting anion‐dominated solvation. This unique solvation environment induces preferential anion decomposition at electrode interfaces, forming robust inorganic rich S/CEI.

Resolution among major placental mammal interordinal relationships with genome data imply that speciation influenced their earliest radiations

open access: yes, 2010
Background: A number of the deeper divergences in the placental mammal tree are still inconclusively resolved despite extensive phylogenomic analyses.

A Catalytic Osmium Redox Couple Collapses Cancer Redox Balance

open access: yesAdvanced Science, EarlyView.
A stable Os(III)/Os(IV) redox couple is developed to disrupt the tumor cell redox balance by concurrently catalyzing ROS generation and GSH depletion. Osmium‐treated cells exhibit multiple cell death pathways, including apoptosis, ferroptosis, and immunogenic cell death.

Biodiversity of flukes

open access: yesParasite, 2008
As many others parasites, speciation of flukes depends on the genetic characteristics and on ploidia. Ploidia of flukes can be different in a same species. In Asia, diploid, triploid and hybrid (2n/3n) populations are encountered.

Deciphering the Dynamic Balance Between Solvation Strength and Polysulfides Reaction Heterogeneity in Practical Lithium‐Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
A weakly solvating fluorinated cosolvent (1200ET) enables precise solvation‐power regulation in Li–S batteries, decoupling interfacial stabilization from sulfur redox kinetics. This approach suppresses polysulfide dissolution while preserving reaction kinetics, leading to a stable Li metal interface and high‐energy multilayer pouch cells, revealing a ...

Enhancing Biogenic Formic Acid Production in the Modified OxFA Process by Acetonitrile Addition

open access: yesAdvanced Science, EarlyView.
In this study, the beneficial effect of using acetonitrile as a co‐solvent in the modified OxFA process is shown, outperforming methanol, demonstrating improved reaction kinetics combined with high selectivity for the HPA‐2 (H5PV2Mo10O40) catalyzed oxidation of xylose to FA.

No evidence for sympatric speciation

open access: yes, 2006
Sympatric speciation is difficult to demonstrate in nature and remains a hotly debated issue. Barluenga et al.1 present a case of putative sympatric speciation for two cichlid species in the Nicaraguan crater lake Apoyo, but they overlook or reinterpret ...
