Inorganic materials which emit light when excited by ultrasound have garnered growing attention. While the phenomenon holds considerable potential for advanced sensing, damage detection, and remote illumination, it has so far been known only for crystalline and often opaque materials. Herein, persistent…
Non-graphitizing (so-called “hard”) carbons, derived from natural and abundant precursors such as biomass, sugars ( e.g. , glucose and sucrose) and polysaccharides ( e.g. , starch and cellulose), are widely investigated as negative electrode materials for alkali metal-ion storage in secondary batteries…

Abstract In contrast to organic and semiconductor ceramic materials, conventional oxide glasses do not typically exhibit pronounced stimulus‐response, stemming from their state of chemical bonding and structural isotropy. However, targeted selection of the glass matrix and additional ion species acting…
Glass optical fibers with well‐defined light‐diffusing properties are an emerging class of light sources for functional and ambient illumination, from photodynamic therapy, agriculture, and photochemistry to architecture and interior design, whenever light with specific spectral characteristics needs…
Zeolites are widely used materials with tunable structures applied in catalysis, ceramics, and glasses. Their unique ability to function in both crystalline and amorphous phases offers broad potential for tailored applications. Controlled amorphization of zeolites enables fine-tuning of performance characteristics.…
Abstract Apatite is present as an accessory phase in many meteorites and is often formed as a secondary product of aqueous alteration. Its propensity to incorporate rare earth elements (REE) results in apatite usually being the main REE‐bearing phase in hydrously altered meteorites. Asteroid Ryugu is…
Abstract Regolith samples returned from asteroid 162173 Ryugu by the Hayabusa2 mission provide direct means to study how space weathering operates on the surfaces of hydrous asteroids. The mechanisms of space weathering, its effects on mineral surfaces, and the characteristic time scales on which alteration…
Zeolitic carrier materials offer ion release and uptake functionality for a wide range of applications. The release kinetics are controlled by the mobility of the target species within the zeolite framework and at its surface. Here, we achieve control over the release dynamics and the quantity of released…
Shock‐induced transformations of quartz to high‐pressure polymorphs and diaplectic glass are decisive in identifying impact cratering events. Under shock compression, quartz can melt in local hot spots and crystallization of these silica melts under pressure can yield the high‐pressure mineral stishovite.…
Pyroxenes, common in Earth’s mantle, mafic crustal rocks, and meteorites, provide insights into processes that took place, for example, in the interior of other planets or during an impact event. To reconstruct correctly the history of a meteorite, it is required to understand the microstructures in…
Abstract Shock‐related calcite twins are characterized in calcite‐bearing metagranite cataclasites within crystalline megablocks of the Ries impact structure, Germany, as well as in cores from the FBN1973 research drilling. The calcite likely originates from pre‐impact veins within the Variscan metagranites…
Abstract Light emission from CaZnOS:Nd 3+ by high‐intensity ultrasound excitation is demonstrated. Acoustic power and duty ratio enable simultaneous control of the degree of (local) thermo‐acoustic heating in isothermal or nonisothermal conditions. The Nd‐related photoemission provides direct thermometric…
An intense ultrasound‐induced luminescence (USL) from Cr 3+ ‐activated glass – ceramic composites, obtained by direct precipitation of nanoscale ZnGa 2 O 4 from silicate melts upon cooling, is reported. The USL band overlaps with the first near‐infrared transmission window of biological tissue and spans…
Knowledge of the shock behavior of planetary materials is essential to interpret shock metamorphism documented in rocks at hypervelocity impact structures on Earth, in meteorites, and in samples retrieved in space missions. Although our understanding of shock metamorphism has improved considerably within…
When affected by impact, quartz (SiO 2 ) undergoes an abrupt transformation to glass lamellae, the planar deformation features (PDFs). This shock effect is the most reliable indicator of impacts and is decisive in identifying catastrophic collisions in the Earth´s record such as the Chicxulub impact.…
Micro- to nanometer-sized metal-volatile related inclusions have been investigated by a combined SEM-FIB-TEM approach within primitive meteorites Acfer 094 and QUE 97990. Acfer 094 contains polycrystalline sulfide-oxide assemblages with concentric character that, in some cases contain relict metal within…
Metal halide perovskites (MHP) represent a class of low-cost and versatile ionic semiconductor materials that have the potential to enter and make a significant impact in the photovoltaic (PV) and sensor markets. Perovskite solar cells (PSC), made from MHP are a rapidly evolving class of next-generation…
Impacts of meteorites and asteroids played an important role in the evolution of the Earth. The most diagnostic indications of past impacts are provided by amorphous lamellae, i.e. planar deformation features (PDFs), in the mineral quartz. Despite the importance of PDFs, the mechanisms leading to their…
Mechanoluminescent (ML) materials, which generate light emission under mechanical stimulus, have attracted more and more attention in recent years due to their mechano-to-optical energy conversion capability. ML materials have been found to have huge potential in various field including force sensing,…
The high‐precision X‐ray diffraction setup for work with diamond anvil cells (DACs) in interaction chamber 2 (IC2) of the High Energy Density instrument of the European X‐ray Free‐Electron Laser is described. This includes beamline optics, sample positioning and detector systems located in the multipurpose…
