Synthesising nanocomposite Co2SnO4@rGO for peroximonosulphate activation in a hybrid ozonation system to effectively degrade cefalexin from wastewater

open access: yesVietnam Journal of Science, Technology and Engineering, 2023
This study successfully developed 2-Co2SnO4@rGO nanocomposites at various composite ratios of 2-Co2SnO4 and rGO using the sol-gel method. These nanocomposites were then used as heterogeneous catalysts to activate PMS in the heterogeneous catalytic ...

CFX: Contention-Free Channel Access for IEEE 802.11ax

open access: yesSensors, 2022
Orthogonal frequency-division multiple access (OFDMA) has attracted great attention as a key technology for uplink enhancement for Wi-Fi, since it can effectively reduce network congestion and channel access delay. Unfortunately, the traditional random access protocol of Wi-Fi seldom allows these benefits to be achieved, especially in dense network ...

CFX Simulations of ROCOM Slug Mixing Experiments

open access: yesJournal of Power and Energy Systems, 2008
The present paper documents the CFD code validation activity carried out at the University of Pisa. In particular, the ANSYS CFX-10.0 code was used to simulate one of the experiments conducted at the ROCOM mixing test facility (FZD, Germany), that reproduced the injection of a de-borated slug in one cold leg of a pressurized water reactor (simulated by

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

open access: yesMolecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...
