گرانیت‌های جنوب مشهد به مساحت تقریبی 40 کیلومترمربع در استان خراسان رضوی قرار دارند. این گرانیت‌ها از نوع  S، پرآلومین و از نظر خاستگاه زمین‌ساخت ماگمایی از نوع برخوردی و کوهزایی هستند که میزبان پگماتیت‌هایی هستند که آنها را قطع کرده‌اند. در این نوشتار به نتایج بررسی‌ها، روی پگماتیت‌های موجود در این گرانیت‌ها از نظر کانی‌سازی لیتیم پرداخته شده است. پگماتیت‌های جنوب مشهد که از نوع ساده (غیر پیچی...

Background: Medulloblastoma is the most common malignant brain tumor in children. The important factors in predicting survival are the extent of disease, proliferation index of the tumor cells, histopathologic class and the age at diagnosis. The percentage of Ki-67 positive cells reflects the proliferation  of the cells and is one of the critical factors which determine the growth of the tumor....

Li metal negative electrode is expected for the next-generation Li battery electrode material, and the control of morphological variation of the Li metal electrode surface is very important issue. In-situ observation of the Li dendrite growth in an ionic liquid by an optical microscope was done in order to discuss the relationship between the Li dendrite growth and the Li ionic mass transfer ra...

Natural lithium (Li) salts, including those used routinely in manic depressive illness, consist of two stable nonradioactive isotopes: lithium-7 (Li-7) (92.6%) and lithium-6 (Li-6) (7.4%). Female rats (3 months old) were treated with either Li-7 chloride or Li-6 chloride or were untreated prior to and during gestation and lactation. Birth weights were lower for Li-treated animals than for norma...

In order to fabrication of transparent glass-ceramics with Li-mica nano crystals, the glasses with chemical composition of 94.9 mass% Li(1+x)Mg3AlSi3(1+x)F2 (x=0.5) with 5.1 mass% MgF2 were crystallized. The glasses were fabricated via the conventional melt-quenching technique. Mica crystals were precipitated in the glass phase by later heat treatment. Glass samples had glass transition tempera...

PbO nanoparticles were synthesized using hydrothermal process. Scanning electron microscopy (SEM) was used in order to investigate of PbO powders. X-ray diffraction (XRD) pattern confirmed β-PbO formation during this process. The crystallite size of the powders was calculated using Scherrer formula about 74.6 nm. Electrochemical evaluation of the PbO nanoparticles as anode for Li-ion batteries ...

The molecular basis for Na/Li exchange is unknown. Li can be transported by the Na pump, anion exchanger (AE1), a background leak, and the Na/Li exchanger. In vivo the intraerythrocyte concentration of Li results from the balance of passive entry, mostly on AE1, and the active extrusion on the Na/Li exchanger. Here we show that erythrocytes have Li-activated PO4 transport that behaves as if it ...
