Magnetic field sensing characteristics of rGO/BiMnO3 nanocomposites loaded clad-modified optical fiber sensor

Journal of Science: Advanced Materials and Devices, 2022
The clad-modified multimode plastic optical fiber (POF) was developed using pristine BiMnO3 (BMO) and BMO/rGO as a sensor material. The BMO and BMO/rGO were synthesized using the hydrothermal method. The structural, morphological, optical, and dielectric

A lens-coupled scintillation counter in cryogenic environment

, 2011
In this work we present an elegant solution for a scintillation counter to be integrated into a cryogenic system. Its distinguishing feature is the absence of a continuous light guide coupling the scintillation and the photodetector parts, operating at ...

KLK7 overexpression promotes an aggressive phenotype and facilitates peritoneal dissemination in colorectal cancer cells

FEBS Open Bio, EarlyView.
KLK7, a tissue kallikrein‐related peptidase, is elevated in advanced colorectal cancer and associated with shorter survival. High KLK7 levels in ascites correlate with peritoneal metastasis. In mice, KLK7 overexpression increases metastasis. In vitro, KLK7 enhances cancer cell proliferation, migration, adhesion, and spheroid formation, driving ...
