No additional supporting electrolyte needed! By utilizing the approved 1,1,1,3,3,3‐hexafluoropropan‐2‐ol (HFIP)/boron‐doped diamond (BDD) system, an electrochemical sulfonylation of arenes and aniline derivatives has been established. The dual function of the sulfinates as supporting electrolyte and coupling substrate, ensures a sustainable and waste ...

Highly Transparent LiAl5O8 Ceramics Prepared by Spark Plasma Sintering and Its Luminescence
ABSTRACT Transparent ceramics of LiAl5O8 were prepared by spark plasma sintering (SPS) using precursor powders synthesized via solid‐state reaction. The effects of sintering dwell time and cooling regime on the microstructure, transparency, and cracking of the sintered ceramics were investigated.

An Overview of Methods for Blast Load Testing and Devices for Pressure Measurement
A brief review of experimental methods for testing blast effects on structures is presented. Methods are classified in four groups: field tests, shock tubes, pendulum systems, and new techniques (blast simulator). Description of each method is given together with overall specification of possible instruments used in each test.

Garnet‐like luminescence upon Ce3+‐activation is found in the first six representatives Li9RESi4N4O8 (RE = Y, La, Gd, Dy, Yb, Lu) of the substance class of lithium rare‐earth oxonitridolithosilicates, which also show a novel structure type. High‐temperature solid‐state synthesis yielded crystalline samples for single‐crystal X‐ray diffraction‐based ...

Geographically multifarious phenotypic divergence during speciation
A male Lycaeides investigates one of the female wing pattern models at Bull Creek in Wyoming. Abstract Speciation is an important evolutionary process that occurs when barriers to gene flow evolve between previously panmictic populations. Although individual barriers to gene flow have been studied extensively, we know relatively little regarding the ...

Interactions of rare earth elements with living organisms and emerging biotechnical applications
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

The ABCs of Experimental Evolution
Microbial evolution is complex and is influenced by many sources of variation. Experimental evolution is no exception, although it is more controlled, easily replicated, and typically devoid of interactions between species. Mathematical modeling of the evolutionary process can help in understanding the underlying mechanisms that drive outcome of such ...

A Simplified Approach for Electrochemical Allylic Oxidation of Olefins
A simple method for electrochemical allylic oxidation of olefins is established. t‐Butyl hydroperoxide serves in a dual‐role as mediator and oxygen source. Metal‐free and robust electrode materials such as glassy carbon, graphite, or boron‐doped diamond can be employed.
