New Late Cretaceous zhelestid mammal from the Bayanshiree Formation, Mongolia [PDF]

Acta Palaeontologica Polonica
Numerous exquisitely preserved mammal fossils unearthed from Upper Cretaceous strata in the Gobi Desert of Mongolia have played a key role in understanding Mesozoic mammalian evolution.

Gobi Altai, Khangai and Khentii Mountains mapped by a mixed-method cartographic approach for comparative geophysical analysis

Mongolian Geoscientist, 2021
Geologic and geophysical mapping has been so far limited to the traditional single-method GIS-based mapping. A new approach combining integrated analysis of data on geology, gravity, topography and geomorphology is presented for regional characterization

Microstructural Evolution and Mechanical Property Degradation of Sn0.5Ag0.7Cu5Bi Solder Joints with High Indium Alloying

Advanced Engineering Materials, EarlyView.
This study identifies 12 wt% indium (In) as the optimal composition for Sn0.5Ag0.7Cu5Bi solder joints, achieving 87% ductile fracture and 81% suppression of intermetallic compound (IMC) growth versus 4 wt% In. High‐In alloys (15–17 wt%) show abnormal IMC thickening due to thermal activation.

Beads and decoration elements made of amber in items of jewelry from the burials of the nomads of Asian Sarmatia in the context of trade in exotic materials in Eurasia

Материалы по археологии и истории античного и средневекового Причерноморья, 2021
If the distribution of amber in Europe has been studied quite fully, then the study of the distribution of amber in Eurasia is replete with white spots. This also applies to amber jewelry among the nomads.

Engineering Active CeO2/Fe3C Interfacial Sites to Generate High‐Charge‐Density Fe for Enhanced Oxygen Reduction Reaction Efficiency

Advanced Functional Materials, EarlyView.
A well‐modulated CeO2/Fe3C heterostructure is successfully constructed. The electron redistribution induced by CeO2 not only enhances the formation energy of Fe vacancies and hinders the dissolution of Fe but also reduces the energy barrier of the ORR.

Microfluidic Synthesis of Channel‐Rich Pd‐Cu Alloy Nanodendrites for Efficient Electrocatalytic CO2 Reduction to Formate

Advanced Functional Materials, EarlyView.
A microfluidic system enables the rapid, room‐temperature fabrication of channel‐rich Pd‐Cu alloy nanodendrites with tunable composition, uniform morphology, and finely branched internal structures. The resulting catalysts exhibit over 90% formate selectivity across a broad potential window, along with excellent CO tolerance and enhanced long‐term ...

Guided Bone Regeneration Membrane Materials Loaded with Chimeric Nanovesicles Promote Early Bone Defect Regeneration

Advanced Healthcare Materials, EarlyView.
Early bone regeneration is challenged by poor osteogenic microenvironments. We developed a novel guided bone regeneration (GBR) membrane: a plasma‐treated polycaprolactone (PT‐PCL) electrospun nanofiber functionalized with ultrasound sequentially extruded stromal vascular fraction chimeric vesicles (USE‐SCNVs). USE‐SCNVs require less equipment, enhance
