Imaging study: air pollution impairs function of blood vessels in lungs

10 December 2016

Air pollution impairs the function of blood vessels in the lungs, according to a study of more than 16,000 patients presented at EuroEcho-Imaging 2016. EuroEcho-Imaging is the annual meeting of the European Association of Cardiovascular Imaging (EACVI), representing members around the world with an interest in all modalities of cardiovascular imaging.

The study examined the effect of air pollution on pulmonary haemodynamics (blood flow) in a population and in individuals. The population study assessed whether common levels of outdoor air pollution influence the echocardiography (ultrasound used to investigate the action of the hear) parameters conventionally used to evaluate the pulmonary circulation and right ventricular function.

Hydrogen from sunlight, but as a dark reaction; time-delayed photocatalytic H2 production

9 December 2016

A team at the Max Planck Institute for Solid State Research, Germany, and collaborators at ETH Zurich and the University of Cambridge, have developed a system that enables time-delayed photocatalytic hydrogen generation—essentially, an artificial photosynthesis system that can operate in the dark. A paper on their work is published in the journal Angewandte Chemie International Edition.

The system uses a carbon nitride-based material that can harvest and store sunlight as long-lived trapped electrons for redox chemistry in the dark. More specifically, the system comprises a partially anionic, cyanamide-functionalized heptazine polymer, which, in the presence of an appropriate electron donor, forms a radical species under irradiation that has a lifetime of more than 10 hours. This ultra-long-lived radical can reductively produce hydrogen in the presence of a hydrogen evolution catalyst in the dark on demand.

Honeywell Transportation Systems Forecast: turbocharged vehicles to account for 48% of annual global sales by 2021; electric boosting emerges

9 December 2016

Honeywell’s Transportation Systems Forecast projects that turbocharged vehicles will acount for 48% of annual global sales by 2021, up 9 percentage points from 2016. This annual sales estimate, combining both passenger and commercial vehicles, would add more than 232 million turbocharged vehicles globally between 2017 and 2021—an increase of 35% from today.

This year’s forecast recognizes an industry trend for slightly bigger engine sizes in Europe and China as automakers adapt powertrain strategies to tackle updated emissions regulations developed for real-world driving conditions. In these regions, a typical powertrain is a three- or four-cylinder engine with a displacement size between 1.2 liters and 1.7 liters. By rightsizing engines with available technologies, automakers are able to continue applying the benefits of smaller turbocharged engines while fine-tuning powertrain systems to further optimize fuel economy, emissions and performance.

JISEA: nuclear-renewable hybrid energy systems can reduce GHG from industry, produce fuels and support the power system

9 December 2016

Nuclear-renewable hybrid energy systems (N-R HESs) can enable low-carbon, on-demand electricity while providing reduced-emission thermal energy for industrial processes. N-R HES systems are managed by a single entity that link a nuclear reactor that generates heat, a thermal power cycle for heat-to-electricity conversion, at least one renewable energy source, and an industrial process that uses thermal and/or electrical energy.

However, the economic feasibility of these systems may depend on future natural gas prices, electricity market structures, and clean energy incentives. A series of new reports from the Joint Institute for Strategic Energy Analysis (JISEA) and Idaho National Laboratory (INL) examines various hybrid system configurations to provide a basis to identify opportunities for clean energy use and examine the most economically viable configurations.

Audi TT 2.0 TDI diesel now also available with quattro all-wheel-drive

8 December 2016

Audi is introducing a quattro all-wheel-drive version of its diesel Audi TT 2.0. (Earlier post.) The new model is now on sale in Europe, and will be available for delivery from the beginning of 2007. Coupled to the S tronic six-speed dual-clutch transmission, the sporty TT diesel quattro Coupé delivers fuel consumption of 5.2 l/100 km (45.2 US mpg) according to the NEDC measuring method, which equates to 137 grams of CO2 per kilometer (220.5 g/mi). The TT Roadster figures are 5.4 l/100 km (43.6 US mpg) and 142 g CO2 per kilometer (228.5 g/mi).

Audi said that one in two Audi TTs sold worldwide is a quattro. The quattro drive uses an electro-hydraulic multi-plate clutch to distribute the torque to both axles. In many everyday driving situations, it will direct the engine’s power predominantly to the front wheels. Should traction decrease there, the clutch continuously redirects the torque to the rear within a few milliseconds.

Global Automakers calls on EPA to withdraw proposed determination on MY 2022-2025 GHG standards, get back in alignment with NHTSA, provide more time

8 December 2016

Global Automakers, the trade association representing the US divisions of 12 international automakers (Aston Martin, Ferrari, Honda, Hyundai, Isuzu, Kia, Maserati, McLaren, Nissan, Subaru, Suzuki and Toyota), has called on the EPA either to withdraw its proposed determination on MY 2022-2025 light duty vehicle greenhouse gas standards or to extend the comment period. On 30 November, EPA proposed leaving the greenhouse gas (GHG) emissions standards for those model years in place, based on its technical analysis that shows automakers are well positioned to meet the targets, and proposed a 30-day comment period. (Earlier post.)

The final standards are projected to result in an average industry fleet-wide level of 163 grams/mile of CO2 in model year 2025, which is equivalent to 54.5 mpg (4.31 l/100 km), if achieved exclusively through fuel economy improvements.
