Bimetallic (NiFe) and Trimetallic (NiFeCr) Nanoalloys from Metal Oxides Using a Microwave Hydrogen Plasma

Advanced Engineering Materials, EarlyView.
Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.

Periprocedural complications after laser balloon ablation procedures for atrial fibrillation: An analysis using a nationwide claims database

Heart Rhythm O2
Background: Evidence regarding the periprocedural safety of laser balloon (LB) catheter ablation for atrial fibrillation (AF) is scarce. Objective: We aimed to investigate the periprocedural safety of LB ablation for AF compared with that of either ...

Radiofrequency Ablation in the Treatment of Liver Metastases of Colorectal Cancer

Acta Medica Martiniana, 2012
Many methods of minimally invasive therapy have been developed in recent years to eliminate tumours in organs like the liver. One of the most promising methods is called radiofrequency ablation, occasionally referred to as RFA. In radiofrequency ablation,

Universal Neuromorphic Element: NbOx Memristor with Co‐Existing Volatile, Non‐Volatile, and Threshold Switching

Advanced Functional Materials, EarlyView.
A W/NbOx/Pt memristor demonstrates the coexistence of volatile, non‐volatile, and threshold switching characteristics. Volatile switching serves as a reservoir computing layer, providing dynamic short‐term processing. Non‐volatile switching, stabilized through ISPVA, improves reliable long‐term readout. Threshold switching operates as a leaky integrate

Randomized clinical trial of endovenous laser ablation versus direct and indirect radiofrequency ablation for the treatment of great saphenous varicose veins

British Journal of Surgery, 2019
The current treatment strategy for many patients with varicose veins is endovenous thermal ablation. The most common forms of this are endovenous laser ablation (EVLA) and radiofrequency ablation (RFA).

A Single‐Metal‐Doped Nanoplatform for Ferroptosis‐Driven cGAS‐STING Pathway Activation in Hepatocellular Carcinoma Immunotherapy

Advanced Functional Materials, EarlyView.
The cGAS‐STING pathway boosts HCC antitumor immunity but lacks specific activation. Nanoplatform ZMRPF induces HCC ferroptosis via lipid ROS, releasing mtDNA. It synergizes with ZMRPF‐released Mn2⁺ to activate cGAS‐STING, amplifies antigen‐presenting cell activity, reverses HCC immunosuppression, and enables robust systemic antitumor immunity ...
