C&EN Senior Editor Alexander Tullo explains that rolling resistance — the friction that tires encounter when rolling — are a major factor in a vehicle’s fuel economy. It can determine up to 20 percent...
Ecology, The Environment and Conservation |Both the new Sitrans P280 transmitter for pressure measurement and the Sitrans TF280 transmitter for temperature feature a WirelessHart interface and a graphical display with backlight function. ...
Machine Engineering |These cells, known as circulating tumor cells, or CTCs, can provide critical information for examining and diagnosing cancer metastasis, determining patient prognosis, and monitoring the effectiveness...
Life Sciences |In industrial environments, especially in power stations and the oil and gas area, leaks in pipe systems, valves and at critical transfer points have to be identified as quickly as possible. This is e...
Information Technology |More than half of the energy consumed worldwide is wasted, most of it in the form of excess heat. This new technology would allow conversion of waste heat into electricity with an efficiency several t...
Physics and Astronomy |The new tires could help add an extra mile or two per gallon to a car's fuel economy. That's the topic of the cover story of the current issue of Chemical & Engineering News, (C&EN) ACS'...
Materials Sciences |An international team of researchers under the umbrella of the Global Carbon Project reports that over the last 50 years the average fraction of global CO2 emissions that remained in the atmosphere ea...
Ecology, The Environment and Conservation |Purdue University and NASA examined more than a dozen chemicals, most of which are generated by humans, and have developed a blueprint for the underlying molecular machinery of global warming. The res...
Life Sciences |For the Panel PCs Simatic HMI IPC477C and HMI IPC577C there are now 12" and 15" devices with keys in addition to the 12", 15" and 19" devices with touch screen. For the Simati...
