A Reproducible SEM Surface Imaging Protocol for Monitoring Microstructural Changes During Gas–Rock Interactions

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Reliable characterization of mineralogical and textural changes in rock samples is essential for understanding fluid–rock interactions, particularly in experimental studies simulating subsurface conditions. This study presents a reproducible protocol for scanning electron microscopy (SEM) analysis of rock surfaces before and after exposure to ...

Effect of explosive detonation velocity on the degree of rock pre-fracturing during blasting

Горные науки и технологии
At many quarries for the extraction of building stone there is a problem of increased output of fines after all stages of crushing and grinding, which leads to a decrease in the economic performance of mining enterprises.

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

Journal of Raman Spectroscopy, EarlyView.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

Surgical caseload and annual volume influence cartilage treatment strategies in primary anterior cruciate ligament reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate how surgeon and clinic volume, along with patient‐, injury‐ and surgery‐related factors, influence cartilage injury management in primary anterior cruciate ligament reconstruction (ACLR). Methods This retrospective cohort study analysed cartilage treatment (debridement, microfracture, other methods or left in situ) in ...

Microfracture for full‐thickness chondral lesions of the knee in elite athletes leads to high return‐to‐play rates

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Injuries to the knee are common in elite athletes and often involve damage to the articular cartilage. Given the high demands of elite sport, full‐thickness articular cartilage defects in the knee can be career‐limiting or threatening.

MOCART 2.0 score of 60 or greater measured at 1 year post‐operatively predicts favourable clinical outcomes after surgical repair of tibiofemoral cartilage lesions

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose (1) To evaluate the relationship between the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) 2.0 score and post‐operative clinical outcomes following surgical repair of cartilage lesions in the tibiofemoral joint, and (2) to determine threshold values of the 1‐year MOCART 2.0 score associated with favourable patient ...
