Surface modification of powder materials has always been a key issue that must be faced to improve their applicationproperties and application value. Herein, an efficient and eco-friendly CH4/CF4 plasma method is used for surface modificationof materials. The surface modification mechanism of fluorocarbon plasma under different gas flow ratios was detailedinvestigated by combining the kinetic analysis. The findings demonstrate that fluorocarbon plasma exhibits differentmodification mechanisms under different modification conditions. The physicochemical properties of the material surface canbe easily controlled by adjusting the ratio of fluorocarbon plasma. Functional CaTiO3 particles with core-shell structure weresuccessfully prepared when the gas flow rate ratio R=3. The modified surface exhibited extreme hydrophobicity and the lowestsurface energy. This strong application of fluorocarbon plasma technology in material surface modification offers a newavenue to prepare environmentally friendly and functional powders.

T-complex protein 10A homolog 2 (TCP10L) was previously demonstrated to be a potential tumor suppressor in human hepatocellular carcinoma (HCC). However, little is known about the molecular mechanism. MAX dimerization protein 1 (MAD1) is a key transcription suppressor that is involved in regulating cell cycle progression and Myc-mediated cell transformation. In this study, we identified MAD1 as a novel TCP10L-interacting protein. The interaction depends on the leucine zipper domain of both TCP10L and MAD1. TCP10L, but not the interaction-deficient TCP10L mutant, synergizes with MAD1 in transcriptional repression, cell cycle G1 arrest and cell growth suppression. Mechanistic exploration further revealed that TCP10L is able to stabilize intracellular MAD1 protein level. Consistently, the MAD1-interaction-deficient TCP10L mutant exerts no effect on stabilizing the MAD1 protein. Taken together, our results strongly indicate that TCP10L stabilizes MAD1 protein level through direct interaction, and they cooperatively regulate cell cycle progression.
