Abstract: Methods of forming a tape-like carbon nanotube (CNT) prepreg that may enhance the shear, transverse and axial mechanical properties of composite articles fabricated using the prepreg. Particularly, tape-like prepregs in which a CNT reinforcement material may be impregnated with a thermosetting resin and thermally latent ionic liquid cure agent. Prepregs may be formed of carbon nanotube reinforcement with specific alignment in one direction and continuous high degree of stretch to yield high tenacity and modulus. The CNT prepreg may have a specific cross-sectional aspect ratio between the prepreg width and the thickness that may result in enhanced shear and transverse strength combined with enhanced axial strength where applied to composite materials.

Abstract: The present invention relates to a method for prevention, alleviation, or treatment of cancer patients, especially epithelial mesenchymal transition (EMP)-subtype cancer patients. If PHGDH, SHMT and MTHFD2 inhibitors are co-administered to patients with cancer in which the expression level of a glutaminase (GLS) gene or a protein encoded thereby has increased, 1C metabolism is more effectively inhibited such that there is a synergistic effect on the inhibition of cancer cell proliferation in patients with refractory cancer that is difficult to treat because of recurrence, metastasis, and anticancer drug resistance, thereby enabling cancer to be very effectively treated. In addition, the expression level of the GLS gene or protein encoded thereby is measured so that information related to customized treatment methods from initial stages is provided to each patient and the success of treatment can be increased.
