Successful cochlear implantation produces a durable, reaction-free surgical site that allows the patient to use his/her implant system comfortably with a cosmetically acceptable appearance.
Developing highly active and durable oxygen reduction reaction (ORR) catalysts is crucial to reduce the cost of polymer electrolyte fuel cells (PEFCs).
The enhanced and durable hydrogen evolution reaction activity stemmed from the synergistic effect broadens noble metal free catalysts for HER and provides an insight into the design and synthesis of low-cost and environment friendly catalysts in electrochemical hydrogen production.
Optimization of electrocatalysts' geometry structure for making them stabilized and more active sites exposed or accessible is one of keys to design the electrocatalysts with highly active and durable oxygen reduction reaction (ORR) performance.
It is of high significance to design efficient, low-cost and durable electrocatalysts for the reaction (OER) in alkaline solution.
The architectures exhibited improved electrocatalytic activity and durable ability toward methanol oxidation reaction (MOR) and oxygen reduction reaction (ORR) in contrast with commercial Pt black and Pd black catalysts.
The one of significant concerns at designs of durable concretes is alkali silica reaction (ASR).
The development of efficient and durable catalyst for oxygen reduction reaction (ORR) is critical for the practical application of proton exchange membrane fuel cell (PEMFC).
The newly designed bimetallic PtCo nanodendrites with a porous dendritic surface offer sufficient molecular accessible active sites and are highly active and durable catalysts for oxygen reduction reaction in comparison with bimetallic PtCo nanoflowers and commercially available Pt/C catalyst.
The super capacitor will be an important contributor to the energy efficient hybrid vehicle, the absence of chemical reaction allowing a durable means of obtaining high-energy charge/discharge cycles.
We show that consideration must be given to the composition of the metal surface of the autoclave, and that by careful choice of reaction conditions, a durable, and impermeable PMMA coating may be deposited within the autoclave.
