Fabrication of a Zircon Microfiltration Membrane for Culture Medium Sterilization

open access: yesMembranes, 2023
Multilayer ceramic membranes to be used for bacteria removal by filtration were prepared from ceramic materials. They consist of a macro-porous carrier, an intermediate layer and a thin separation layer at the top.

Application of Ti-in-zircon thermometry to granite studies: problems and possible solutions

open access: yesContributions to Mineralogy and Petrology, 2019
The application of the Ti-in-zircon thermometer to granitic rock requires consideration of $$a_{{{\text{TiO}}_{2} }}$$aTiO2 and $$a_{{{\text{SiO}}_{2} }}$$aSiO2 during zircon crystallization.

Neutrophil‐Driven Cascade‐Targeted Nanocarriers Restore Mitochondrial Homeostasis to Ameliorate Renal Ischemia–Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
A neutrophil‐mediated dual‐targeting liposome (NKN‐LNP) is developed to treat renal ischemia–reperfusion injury. The system enables spatiotemporally controlled delivery of NMN to injured tubules via MMP‐2/9 activation and KIM1 recognition, restoring mitochondrial function through NAD+‐SIRT3 signaling and preventing the transition from acute kidney ...

Late Cenozoic metamorphic evolution and exhumation of Taiwan [PDF]

open access: yes, 2007
The Taiwan mountain belt is composed of a Cenozoic slate belt (Hsuehshan Range units, HR, and Backbone Slates, BS) and of accreted polymetamorphic basement rocks (Tananao Complex, TC).

Metabolic Imbalance Triggers Adaptive Remodeling to Accelerate Diploidization in Murine Haploid Embryonic Stem Cells

open access: yesAdvanced Science, EarlyView.
In this article, Shuai and colleagues demonstrate that metabolic remodeling drives self‐diploidization in murine haploid ESCs (haESCs). Mitochondrial dysfunction and imbalanced pyruvate metabolism underlie this process. Genome‐wide screening using haESCs identifies key mitochondrial quality‐control related genes, enabling a metabolism‐based medium that

Sr-Nd isotopic characteristic, U-Pb zircon geochronology, and petrogenesis of Najmabad Granodiorite batholith, Eastern Iran

open access: yesJournal of Economic Geology, 2012
The study area is located south of Ghonabad in Eastern Iran. This area is situated between two major faults, Darouneh to the north and Dashtbyaz to the south. The movements of these faults cased major dislocation of this block.

Geochronology of the Suomenniemi rapakivi granite complex revisited: Implications of point-specific errors on zircon U-Pb and refined λ87 on whole-rock Rb-Sr [PDF]

open access: yesBulletin of the Geological Society of Finland, 2015
Multi-grain isotope dilution and secondary ion microprobe zircon U-Pb as well as wholerock Rb-Sr isotope dilution data on the late Paleoproterozoic Suomenniemi rapakivi granite complex (exposed on the northern flank of the Wiborg batholith in ...

Congo River sand and the equatorial quartz factory [PDF]

open access: yes, 2019
A never solved problem in sedimentary petrology is the origin of sandstone consisting exclusively of quartz and most durable heavy minerals. The Congo River offers an excellent test case to investigate under which tectonic, geomorphological, climatic ...

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known
