Flow parameters measurement facilitates the understanding of two-phase flow. Due to the changeable structures of the flow, the prediction of superficial velocity of oil-water two-phase flow in large diameter pipes is still a challenging problem. Therefore, we first conducted a vertical upward oil-water two-phase flow experiment in a 125 mm ID pipe, and obtained the response signals under different flow conditions by a vertical multi-electrode array (VMEA) conductance sensor.

Nasopharyngeal carcinoma (NPC) is a highly invasive malignancy with cervical lymphopathy as the initial presentation. Epithelial‑mesenchymal transition (EMT), a process by which epithelial cells lose cell‑cell adhesion and gain migratory and invasive properties, has a pivotal role in metastasis. Forkhead box C1 (FoxC1), a member of the forkhead family of transcription factors, induces EMT and has a critical role in metastasis of multiple human cancers.

Through in-situ reduction of silver nitrate without using any coupling-agent, a substrate for surface-enhanced Raman scattering (SERS) was prepared by coating silver on hollow buoyant silica microspheres as a lab on a bubble (LoB). The silver coated LoBs (LoBs@Ag) floated on surface of a solution could provide a very convenient platform for the detection of target molecules in the solution. The LoBs@Ag substrate not only immobilized well-distributed Ag nanoparticles on the surface LoBs, but excluded the interference of coupling agents.
