Mineral chemistry and petrogenesis of the Gurgur Mount volcanic rocks (Northeast Takab) [PDF]

open access: yesپترولوژی, 2016
Andesitic and andesitic-basaltic lavas are widespread over most of the ground surface of the Gurgur area altered mostly by the hydrothermal solutions.

Mechanisms of Degradation in Li‐Ion Batteries Under Low Temperature Exposures

open access: yesAdvanced Functional Materials, Volume 36, Issue 71, 3 September 2026.
Low‐temperature exposures, or freeze‐thaw cycles, are observed to significantly accelerate the degradation of Li‐ion batteries. A combination of electrolyte phase separation and mechanochemical stress leads to reversible and irreversible performance losses.

Toward a Suitable Anode Surface for High Voltage Li Ion Batteries: Suppressing Transition Metal‐Induced Degradation via a Coordinating Solid Electrolyte Interphase

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 9, September 2026.
High voltage Li ion batteries with oxide‐based cathodes, here LiNi0.6Co0.2Mn0.2O2 (NCM622), suffer from transition metal (TM) dissolution, which damages the anode (electrode crosstalk). Here, the design of the anode “high voltage solid electrolyte interphase (SEI)” is shown to be effective in suppressing this failure cascades via scavenging the TMs ...

Poikilitic hornblende pyroxenite in the southern end of the Abukuma Mountains, Northeast Japan, as result of adakitic magmatism

open access: yesFrontiers in Geochemistry
Amphibole plays a pivotal role in mediating the flux of volatiles and partial melting that ultimately contribute to arc magmatism. The influence of amphibole from the lower crust to the upper mantle remains unclear due to limited opportunities for ...

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

Phosphorus zoning as a recorder of crystal growth kinetics : application to second-generation olivine in mantle xenoliths from the Cima Volcanic Field [PDF]

open access: yes, 2017
Composite mantle xenoliths from the Cima Volcanic Field (CA, USA) contain glassy veins that cross-cut lithologic layering and preserve evidence of lithospheric melt infiltration events.

ZONING DESIGN FOR HAND­WRITTEN NUMERAL RECOGNITION [PDF]

open access: yes, 1997
Microsoft, Motorola, Siemens, Hitachi, IAPR, NICI, IUF In the field of Optical Character Recognition (OCR), zoning is used to extract topological information from patterns. In this paper zoning is considered as the result of an optimisation problem and a

Metamorphism on Chromite Ores from the Dobromirtsi Ultramafic Massif, Rhodope Mountains (SE Bulgaria)

open access: yesGeologica Acta, 2009
Podiform chromitite bodies occur in highly serpentinized peridotites at Dobromirtsi Ultramafic Massif (Rhodope Mountains, southeastern Bulgaria). The ultramafic body is believed to represent a fragment of Palaeozoic ophiolite mantle.
