- THF is widely used in various applications, including depositing molecules and electrochemical reactions, making it important to understand its effects on surface morphology.
- This unique influence of THF compared to other solvents could unlock new possibilities for catalysis and the nanostructuring of surfaces.
Article Abstract
Exposure of a clean gold surface to tetrahydrofuran (THF) under ambient conditions was observed to cause roughening of atomic step edges. This change was followed in situ using a scanning tunneling microscope during the exposure of a gold surface to a controlled stream of THF vapor. THF is a common solvent used in depositing molecules, self-assembled monolayers, and polymer films on surfaces, in electrochemistry, and in chemical reactions. Unlike other solvents, such as methanol, ethanol and diethyl ether, however, we found that THF itself has a profound effect on the surface morphology that needs to be taken into account when reporting on the interactions of solutes with a gold surface. At the same time, this finding may present new opportunities in catalysis or nanostructuring of surfaces.

A symmetrical dual-D and dual-core single-mode fiber surface plasmon resonance (SPR) liquid sensor is designed for biological detection. The dual-core design optimizes the transmission path, improves the momentum matching between free electrons and photons, and facilitates bidirectional coupling, consequently amplifying the SPR effect and enabling sensitive monitoring of the refractive index changes of biological solutions. In this structure, a gold wire is placed in the middle of the polished surface of the double-D-shaped single-mode fiber (SMF) to produce high-quality free electrons and promote the mode-coupling excitation of the SPR effect.

The cystic artery is a critical anatomical landmark in both laparoscopic and open cholecystectomy. This report presents a unique case involving two rare anatomical variations: double cystic arteries, along with a superficial branch originating from the superior mesenteric artery (SMA) - a previously unreported combination with significant clinical and surgical implications. Unlike earlier studies, this research provides detailed anatomical and embryological insights supported by high-quality imaging and illustrations to guide surgeons in recognizing and managing this novel variation.

Antibiotic residue detection plays an important role in protecting human health, but real-time, rapid, and highly sensitive detection is still challenging. Herein, gold and silver nanoparticles (Au-Ag NPs) were grown on the surface of optical fibers and a 50 nm thick gold film was deposited on the sensor's surface to fabricate the Au-Ag@Au fiber SPR sensor. The sensitivity of the sensor reached 3512 nm per RIU in the refractive index range of 1.
