On December 16th, 2015, the superconducting gravimeter SG038 started to measure again after it was moved from the previous station in Concepcion, Chile to the Argentine-Germany Geodetic Observatory (AGGO) near the city o...

The configuration of the Northern Hemisphere ice sheets during the Last and Penultimate Glacial Maxima (LGM; PGM) influenced millennial-scale climate changes, as well as solid Earth and sea level changes that occurred du...

Charge-trapping defects in crystalline solids play important roles in applications ranging from microelectronics, optical storage, sensing and quantum technologies. On one hand, depleting trapped charges in the host matr...

ObjectiveDeveloped a method based on solid phase extraction（SPE） combined with gas chromatography-mass spectrometry （GC-MS） to determine 1，2-propanediol in milk.MethodsThe precipitation technology of protein an...

Rare-earth dopants are arguably one of the most studied optical centers in solids, with applications spanning from laser optoelectronics, biosensing, lighting to displays. Nevertheless, harnessing rare-earth dopants’ e...

Sr3Al32O51:Eu3+ phosphor prepared successfully by simple combustion method. Prepared matrix synthesized for different percentage of composition for rare earth Eu3+ = (0.5, 1.0, 1.5, 2.0 and 2.5). Photoluminescence proper...

Los suelos de la planicie Pampeana Austral, desarrollados a partir de sedimentos loéssicos tienen horizontes cálcicos evolucionados en el presente ciclo (Ck) y/o heredados (2Ck) y petrocálcicos (2Ckm) asociados a pale...

Abstract Rare earth (RE) elements have positive effects on Al alloy, while most research is focused on microstructure and mechanical properties. As important application indices, toughness and plasticity are properties t...

Converting phonons to photons with optomechanical interaction provides a pathway to realize single phonon counting, which is instrumental in the quantum applications of mechanical systems such as entanglement generation,...

De acordo com os princípios da Agenda 21, o principal documento resultante da unced-92, a sociedade sustentável do futuro deverá mostrar um desenvolvimento econômico equilibrado, no mundo todo, em harmonia com os sis...

Polycrystalline Sr1−xTi0.9Nb0.1O3−δ (x = 0, 0.1, 0.2) ceramics have been prepared by the solid state method and their structural and thermoelectric properties have been studied by neutron powder diffraction (NPD), t...

Abstract Accurate measurements of Earth gravity and its variations with time are crucial not only for fundamental research on gravitation in physics, but also for other scientific areas including Earth sciences, geophysi...

Formic acid, a major product of biomass processing, is regarded as a potential liquid carrier for hydrogen storage and delivery. The catalytic dehydrogenation of FA to generate hydrogen using heterogeneous catalysts is o...

Through the lens of bulk-rock and matrix glass geochemistry, we investigated the magmatic evolution and pre-eruptive architecture of the siliceous magma complex beneath the Cerro Blanco volcanic complex, a Crater Laketyp...

Context. The search for extrasolar planets around the nearest M dwarfs is a crucial step toward identifying the nearest Earth-like planets. One of the main challenges in this search is that M dwarfs can be magnetically a...

The Greenland Ice Sheet is a key component of the Earth’s climate system and assessing its mass balance is crucial for predicting sea-level rise. Solid ice discharge is a critical parameter that can be determined by ca...

Epitaxial semiconductor quantum dots (QDs) have been demonstrated as on-demand entangled photon sources through biexciton–exciton (XX-X) cascaded radiative processes. However, perfect entangled photon emitters at the s...

Outstanding questions about the RNA world hypothesis for the emergence of life on Earth concern the stability and self-replication of prebiotic aqueous RNA. Recent experimental work has suggested that solid substrates an...

Continental denudation has been the center of attention of a reduced and select group of outstanding specialists for several decades. The foci have been placed in queries such as how much solid and dissolved material is ...
