Abstract. The use of low-cost sensors for air quality measurements has become very popular in the last few decades. Due to detrimental effects particulate matter (PM) on human health, PM like photometers and optical particle counters (OPCs) are widespread have been widely investigated. negative high relative humidity (RH) fog events mass concentration readings these types well documented. In li...

The electrical power grid faces a growing need for large-scale energy storage over a wide range of time scales due to costly short-term transients, frequency regulation, and load balancing. The durability, high power, energy efficiency, and low cost needed for grid-scale storage pose substantial challenges for conventional battery technology. (1, 2) Here, we demonstrate insertion/extraction of...

Unlike silver and gold, aluminum has material properties that enable strong plasmon resonances spanning much of the visible region of the spectrum and into the ultraviolet. This extended response, combined with its natural abundance, low cost, and amenability to manufacturing processes, makes aluminum a highly promising material for commercial applications. Fabricating Al-based nanostructures w...

Fujitsu’s MB86H06 set-top box (STB) chip is a high-density chip featuring high-performance, superior error concealment, robust audio-video (AV) synchronization, and low cost. It comprises a QFP256 package with DDR2 memory and supports a two-layer printed circuit board (PCB) layout for a low bill of material (BOM) cost. It is widely used in the China terrestrial television broadcasting (CTTB) ma...

There is a paucity of low-fidelity and cost-efficient simulators for training cardiac surgeons in the aspects of aortic root/valve replacement. In this study we addressed this training challenge by creating a low-fidelity, low-cost but, at the same time, anatomically realistic aortic root replacement simulator for training purposes. We used readily available, low cost materials such as lint rol...
