Dual-gated tunable absorption in graphene-based hyperbolic metamaterial

AIP Advances, 2015
The use of a dual-gated tunable absorber in graphene-based hyperbolic metamaterial (GHMM) in the near-infrared frequency range was investigated. The horizontal and vertical parts for relative permittivity of GHMM, which consists of monolayer graphene and

Effective removal of cation dyes from aqueous solution using robust cellulose sponge

Journal of Saudi Chemical Society, 2020
Cellulose sponge was proposed to an attractive bio-absorbent owing to its highly efficient, low-cost, biodegradable, and renewable sourcing. In this work, the wasted cotton linter as raw materials, the highly porous and lightweight cellulose sponges were

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

Molecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

Gas Absorption with Chemical Reaction in Turbulent Flow [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 1993
In order to increase the rate of gas absorption, chemical reaction in the liquid phase is considered. The purpose of this paper was to simulate gas absorption process by a liquid film over a spherical packing incorporating eddy viscosity and diffusivity.

Chemical Absorption and Mass Transfer of Greenhouse Gas Carbon Dioxide

Chemical Engineering Transactions, 2018
The findings regarding CO2 emissions and efficient absorption of CO2 have important implications for controlling the greenhouse effect. This paper describes the preparation of a mixture with mono ethanol amine (MEA) and N-methyldiethanolamine (MDEA) for ...

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

Molecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.
