Rechargeable lithium-metal batteries with a cell-level specific energy of >400 Wh kg-1 are highly desired for next-generation storage applications, yet the research has been retarded by poor electrolyte-electrode compatibility and rigorous safety concerns. We demonstrate that by simply formulating the composition of conventional electrolytes, a hybrid electrolyte was constructed to ensure high (electro)chemical and thermal stability with both the Li-metal anode and the nickel-rich layered oxide cathodes. By employing the new electrolyte, Li∥LiNi0.6 Co0.2 Mn0.2 O2 cells show favorable cycling and rate performance, and a 10 Ah Li∥LiNi0.8 Co0.1 Mn0.1 O2 pouch cell demonstrates a practical specific energy of >450 Wh kg-1 . Our findings shed light on reasonable design principles for electrolyte and electrode/electrolyte interfaces toward practical realization of high-energy rechargeable batteries. To develop a simulation model for GammaMed Plus high dose rate Ir brachytherapy source in TOPAS Monte Carlo software and validate it by calculating the TG-43 dosimetry parameters and comparing them with published data. We built a model for GammaMed Plus high dose rate brachytherapy source in TOPAS. The TG-43 dosimetry parameters including air-kerma strength S , dose-rate constant Λ, radial dose function g (r), and 2D anisotropy function F(r,θ) were calculated using Monte Carlo simulation with Geant4 physics models and NNDC Ir spectrum. Calculations using an old Ir spectrum were also carried out to evaluate the impact of incident spectrum and cross sections. The results were compared with published data. For calculations using the NNDC spectrum, the air-kerma strength per unit source activity S /A and Λ were 1.0139×10 U/Bq and 1.1101cGy.h .U , which were 3.56% higher and 0.62% lower than the reference values, respectively. The g (r) agreed with reference values within 1% for radialbe used for future studies. The impact of updated incident spectrum and cross sections on the dosimetry parameters was quantified.This study aims to investigate if the radiosensitivity of non-small cell lung cancer (NSCLC) cells can be regulated by long noncoding RNA (lncRNA) colon cancer associated transcript1 (CCAT1). CCAT1 was detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) in NSCLC cells (A549, H1299, SK-MES1, H460, and H647) and human bronchial epithelial cells (16HBE). H460 and A549 cells were then selected for the determination of CCAT1 expression after exposure to radiation (0, 2, 4, 6 Gy) at different time points (0, 6, 12, 24 h). Colony forming assay was performed to evaluate the effects of CCAT1 siRNA or pcDNA3.1-CCAT1 vector on the radiosensitivity of H460 and A549 cells. Then, flow cytometry, western blotting and qRT-PCR were also conducted. CCAT1 was increased in NSCLC cells when compared with 16HBE cells, which was declined in a time- and dosage-dependent manner after exposure to radiation. The H460 and A549 cell colonies were decreased and the γ-H2AX expression was elevated with the increase of radiation dosage, which was more obvious in those transfected with CCAT1 siRNA. selleck CCAT1 downregulation arrested NSCLC cells at G2/M phase. Moreover, the enhanced apoptosis of radiotherapy-treated NSCLC cells with reductions of p-p38/p38, p-ERK/ERK, and p-JNK/JNK was promoted by siCCAT1, but it was reversed by pcDNA3.1-CCAT1 vector. Inhibiting CCAT1 regulated cell cycle, DNA damage and apoptosis of NSCLC cells, and affected MAPK pathway, eventually improving the radiosensitivity of NSCLC.
