AI Article Synopsis
- Thermoelectric generators are being looked at as a convenient energy source for volcano monitoring stations because they are compact and generate power continuously.
- To ensure their effectiveness, it's crucial that the materials used can resist the harsh acidic conditions found in volcanic environments.
- After a year of testing various metal materials buried in the Teide volcano, copper, brass, and galvanized steel showed significant corrosion, leading to the recommendation of AISI 304 and AISI 316 stainless steels as better options for heat exchangers in these thermoelectric devices.
Article Abstract
Thermoelectric generators have emerged as an excellent solution for the energy supply of volcanic monitoring stations due to their compactness and continuous power generation. Nevertheless, in order to become a completely viable solution, it is necessary to ensure that their materials are able to resist in the acidic environment characteristic of volcanoes. Hence, the main objective of this work is to study the resistance to corrosion of six different metallic materials that are candidates for use in the heat exchangers. For this purpose, the metal probes have been buried for one year in the soil of the Teide volcano (Spain) and their corrosion behavior has been evaluated by using different techniques (OM, SEM, and XRD). The results have shown excessive corrosion damage to the copper, brass, and galvanized steel tubes. After evaluating the corrosion behavior and thermoelectric performance, AISI 304 and AISI 316 stainless steels are proposed for use as heat exchangers in thermoelectric devices in volcanic environments.

In this research work, four distinct WO electrodes were synthesized and coated with three different polymers, known as polypyrrole (PPy), poly(3,4-ethylenedioxythiophene) in poly(4-styrenesulfonate) (PEDOT:PSS) and polyaniline (PANi), using electropolymerization techniques. The morphological features of the samples were thoroughly characterized through Field Emission Scanning Electron Microscopy (FE-SEM) and Atomic Force Microscopy (AFM) analyses. Additionally, contact angle measurements and electrochemical characterizations were used to verify the performance of each electrode, aiding in the prediction of their suitability for energy storage applications in lithium-ion batteries.

Magnesium (Mg) and its alloys are revolutionizing the field of interventional surgeries in the medical industry. Their high biocompatibility, biodegradability, and a similar elastic modulus to natural bone make porous Mg-based structures potential candidates for orthopedic implants and tissue engineering scaffolding. However, fabricating and machining porous Mg-based structures is challenging due to their complexity and difficulties in achieving uniform or gradient porosity.

Hydroxyapatite (HA) is an engineered biomaterial that closely resembles the hard tissue composition of humans. Biological HA is commonly non-stoichiometric and features lower crystallinity and higher solubility than stoichiometric HA. The chemical compositions of these biomaterials include calcium (Ca), phosphorus (P), and trace amounts of various ions such as magnesium (Mg), zinc (Zn), and strontium (Sr).

Great attentions have been paid to anticorrosion coatings with self-healing performances to enhance its reliability and protection period, but massive challenges still remain for developing a coating with selectively triggered and accurately controllable self-healing behaviors. Herein, by integrating lamellar graphene oxide (GO) into a polycaprolactone (PCL) nanofiber loaded with 8-hydroxyquinoline (8HQ) corrosion inhibitors, a composite coating with precisely controllable self-healing capabilities is developed. The coating defects can be remotely and accurately repaired under near-infrared (NIR) light irradiation within a very short time.

The practical applications of aqueous Zn metal batteries are promising, yet still impeded by the corrosion reactions and dendrite growth on the Zn metal anode. Here, a self-adsorbed monolayer (SAM) is designed to stabilize the Zn metal anode. Theory and experiment results show that the interfacial confinement effect of the SAM, for one thing, greatly suppresses the corrosion reactions through the HO-poor inner Helmholtz plane because of the steric-hindrance effect, and for another, alleviates the Zn concentration gradient on the anode surface through the Zn enrichment behavior and eventually inhibits the dendrite growth.
