Lead-free relaxor ferroelectric ceramics are potential for energy storage applications due to their comprehensive energy storage properties. However, the energy efficiency of many relaxor ceramics is not high enough, leading to high Joule heat during the charge-discharge cycles, thus lowering their energy storage performance. In this work, tantalum (Ta) dopants were introduced into sodium niobate-based relaxor ceramics to improve the resistivity and energy efficiency. The leakage current was reduced by Ta doping, especially at the high electric field. The enhanced resistivity is attributed to the increased bandgap induced by Ta doping. The impedance spectroscopy shows that both the grain and grain boundary resistivities are improved in the high temperature region. As a result, the optimal recoverable energy density and energy efficiency are 6.5 J/cm3 and 94% at 450 kV/cm, respectively. In addition, the energy storage properties exhibit satisfactory temperature stability and cycling rel ....
Siandhara Bonnet Rapid City Journal RAPID CITY, S.D. â Residents of Hideaway Hills, a neighborhood northwest of Rapid City, may have more answers in the next few weeks about the extent and stability of the abandoned gypsum mine residing underneath their homes. Dr. Mohammad Sadeghi told residents Sunday that his team could have their findings in two to three weeks after using three methods to study the extent of the mine. âI really hope to get some answers for the residents here,â he said. âI think we might have enough to at least give some information.â Grace Pritchett, Journal staff ....
Gaia Metals Corp.: Gaia Metals to Complete IP-Resistivity Survey at the Freeman Creek Gold Property, Idaho, USA Gaia Metals Corp. (the Company ) (TSXV: GMC)(OTCQB: RGDCF)(FSE: R9G) is pleased to announce its plans to complete a 16-line km induced polarization and resistivity (IP-Resistivity) geophysical survey this spring at the Company s wholly owned Freeman Creek Gold Property (the Property ). The Property is located 15 km northeast of Salmon, Idaho, and is road accessible year-round. The objective of the survey at the Carmen Creek Prospect is to locate any additional and yet to be discovered parallel trending mineralised structures, as well as further trace them along strike. In addition, the survey will probe to depths of approximately 120 m and allow for further discrimination of targets along the strike of the structure(s). The data obtained will be integrated with the Company s existing datasets, and used to confirm and prioritize the initial drill hol ....
Emgold Mining Corporation: Emgold Commences IP and Resistivity Study at Its Golden Arrow Property, NV (OTC PINK:EGMCF)(FRA:EMLM) ( Emgold or the Company ) announces that it has contracted with Zonge International Inc. to perform an induced polarization ( IP ) and resistivity ground geophysics survey (the Survey ) at its Golden Arrow Property, NV (the Property ). The Survey will cover an area south of known resource areas of Gold Coin and Hidden Hill and include the area of the 137 new unpatented lode mining claims recently staked by Emgold (see January 12, 2021 press release). The goal of the Survey is to identify additional exploration targets on the Property. ....
