Tunnel junctions based on interfacial two dimensional ferroelectrics.

Van der Waals heterostructures have opened new opportunities to develop atomically thin (opto)electronic devices with a wide range of functionalities. The recent focus on manipulating the interlayer twist angle has led to the observation of out-of-plane room temperature ferroelectricity in twisted rhombohedral bilayers of transition metal dichalcogenides. Here we explore the switching behaviour of sliding ferroelectricity using scanning probe microscopy domain mapping and tunnelling transport measurements.

Axillary reverse lymphatic mapping reduces patient perceived incidence of lymphedema after axillary dissection in breast cancer.

Background: Lymphedema is a feared complication of many patients following axillary lymph node dissection for breast cancer. Axillary reverse lymphatic mapping (ARM) was adopted to decrease the incidence of lymphedema.

Methods: A retrospective review was conducted on 139 patients with breast cancer who had greater than 10 lymph nodes removed.
