Steam oxidation of advanced high temperature resistant alloys for ultra-supercritical applications [PDF]

, 2012
Steam oxidation of heat exchanger tubing is of growing interest as increasing the efficiencies of conventional pulverised fuel fired power plants requires higher steam temperatures and pressures.

Selective C–H oxidation catalyzed by metalloporphyrins [PDF]

, 2011
Selective oxidation of saturated C–H bonds remains a challenge in modern chemistry. The inert nature of such bonds requires the use of highly reactive reagents, and this poses major challenges in terms of chemo, regio and stereoselectivity ...

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Reduction of Parasitic Capacitance in Vertical MOSFETs by Spacer Local Oxidation [PDF]

, 2003
Application of double gate or surround-gate vertical metal oxide semiconductor field effect transistors (MOSFETs) is hindered by the parasitic overlap capacitance associated with their oayout, which is considerably larger than for a lateral MOSFET on the

CO selective oxidation in a microchannel reactor for PEM fuel cell [PDF]

, 2004
It is indispensable to remove CO at the level of less than 50ppm in H-2-rich feed gas for the proton exchange membrane (PEM) fuel cells. In this paper, catalyst with high activity and selectivity, and a microchannel reactor for CO preferential oxidation (

Selective Oxidation of Zirconium in Zr2Cu

Croatica Chemica Acta, 1999
The high-temperature oxidation of Zr2Cu in dry oxygen is characterized by selective oxidation of zirconium. The excess of copper is accumulated in the matrix alloy at the alloy-oxide interface forming the Zr8Cu5 phase. The oxide layer consists of monoclinic ZrO2 and a small amount of CuO. Additionally, tetragonal ZrO2 appears up to 873 K at the surface,

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Polyvinylpolypyrrolidoniume tribromide (PVP-Br3) as efficient and metal-free agent for the selective oxidation of alcohols, trimethylsilyl ethers and oximes under mild conditions

Journal of Saudi Chemical Society, 2017
Polyvinylpolypyrrolidoniume tribromide (PVP-Br3) was found to be a metal-free and highly efficient oxidizing polymer for the selective oxidation of a variety of benzylic alcohols, deprotection and selective oxidation of trimethylsilyl ethers and oximes ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
