Preparation of Nitrogen Doped Biochar-Based Iron Catalyst for Enhancing Gasoline-Range Hydrocarbons Production.

Developing catalysts to obtain high space time yield (STY) of gasoline-range hydrocarbons via Fischer-Tropsch synthesis (FTS) is a huge challenge due to the restriction of Anderson-Schulz-Flory distribution. Herein, a nitrogen doped biochar-based iron catalyst was synthesized by a one-step method using sugar cane bagasse as carbon precursor, which exhibited an excellent gasoline STY of 8.65 g g h, exceeding most reported catalysts.

Biosugarcane-based carbon support for high-performance iron-based Fischer-Tropsch synthesis.

Exploiting new carbon supports with adjustable metal-support interaction and low price is of prime importance to realize the maximum active iron efficiency and industrial-scale application of Fe-based catalysts for Fischer-Tropsch synthesis (FTS). Herein, a simple, tunable, and scalable biochar support derived from the sugarcane bagasse was successfully prepared and was first used for FTS. The metal-support interaction was precisely controlled by functional groups of biosugarcane-based carbon material and different iron species sizes.

An Na-modified Fe@C core-shell catalyst for the enhanced production of gasoline-range hydrocarbons Fischer-Tropsch synthesis.

Although numerous studies have been conducted in the field of converting syngas to value-added fuels, selectively converting syngas to gasoline-range hydrocarbons (C hydrocarbons) remains a big challenge. Alkali metal (namely, K, Na and Li)-modified Fe@C core-shell catalysts were synthesized by a one-step hydrothermal method for Fischer-Tropsch synthesis. An optimized selectivity of 56% for the C hydrocarbons with a higher CO conversion of about 95% was obtained for the FeNa@C catalyst compared to that for other alkali metal-modified Fe@C catalysts.

FOXC2 often overexpressed in glioblastoma enhances proliferation and invasion in glioblastoma cells.

Glioblastoma (GBM) is the most common primary brain tumor and the leading cause of tumor-related death in the central nervous system. To date, the mechanisms of GBM genesis remain elusive. Forkhead box protein C2 (FOXC2) is a transcription factor that has been reported in many cancers, but its function in GBM tumorigenesis is not clearly elucidated.

Microsurgical treatment for parasagittal meningioma in the central gyrus region.

The aim of the present study was to determine the efficacy of microsurgery treatment for parasagittal meningioma in the central gyrus region. A microsurgical technique was used to treat 26 patients with large parasagittal meningioma in the central gyrus region. The Rolandic and draining veins and the peritumoral normal brain tissue were retained, and the associated sagittal sinus was appropriately protected.
