Unusual High Oxygen Reduction Performance in All-Carbon Electrocatalysts
Carbon-based electrocatalysts are more durable and cost-effective than noble materials for the oxygen reduction reaction (ORR), which is an important process in energy conversion technologies. Heteroatoms are considered responsible for the excellent ORR performance in many carbon-based electrocatalysts. But whether an all-carbon electrocatalyst can effectively reduce oxygen is unknown. We subtl...
متن کاملA Class of High Performance Metal-Free Oxygen Reduction Electrocatalysts based on Cheap Carbon Blacks
For the goal of practical industrial development of fuel cells, cheap, sustainable and high performance electrocatalysts for oxygen reduction reactions (ORR) which rival those based on platinum (Pt) and other rare materials are highly desirable. In this work, we report a class of cheap and high-performance metal-free oxygen reduction electrocatalysts obtained by co-doping carbon blacks with nit...
متن کاملHigh Performance Parallel Prefix Adders with Fast Carry Chain Logic
Binary adders are the basic and vital element in the circuit designs. Prefix adders are the most efficient binary adders for ASIC implementation. But these advantages are not suitable for FPGA implementation because of CLBs and routing constraints on FPGA. This paper presents different types of parallel prefix adders and compares them with the Simple Adder. The adders are designed using Verilog...
متن کاملDesign and fabrication of high density borated polyethylene nanocomposites as a neutron shield
Background: Polyethylene composites including boron can be used as an effective neutron shield. Our investigation focuses on manufacturing borated polyethylene nano-composite. The purpose of this study is to design a radiation shield for use in both neutron and gamma fields. Materials and Methods: Borated polyethylene shields containing 2%, and 5% weight percentage of Boron nano-particles w...
متن کاملThe "FDA approval defense": penetrating the protective shield.
Pharmaceutical manufacturers decry the purported burdens imposed by Federal regulation when it suits their proprietary interests, yet they sing a wholly different tune when defending product liability suits. As product liability defendants, they unabashedly seek the protective womb of Food and Drug Administration (FDA) regulation, arguing that agency approval of their drug and its labeling prec...
