Candida rugosa lipase nanoparticles as robust catalyst for biodiesel production in organic solvents [PDF]

Biofuel Research Journal, 2019
Inexpensive but resourceful sources of lipids, for example, used cooking oil (UCO) and brown grease (BG), which often contain large amounts of free fatty acids (FFA), are difficult to convert into biodiesel economically and in good yield.

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

The sustainability of Russia's energy power: implications for the Russian economy [PDF]

, 2007
To what extent and through what mechanisms has Russian economic growth since 1998 been dependent on Russia's oil and gas industries? Is the likely development of these industries up to 2020 capable of maintaining or increasing Russia's role as an energy ...

Climate Action Impacts on Steelmaking Emissions of Persistent Organic Pollutants Highlight a Gap Between the Paris Agreement and the Stockholm Convention

Advanced Science, EarlyView.
Emissions of unintentionally produced persistent organic pollutants (UPOPs) and global warming are two major environmental challenges. But their governance has largely evolved in parallel, leaving the toxicity implications of climate‐driven industrial transitions poorly understood.

Energy Conservation as Security [PDF]

, 2006
"Energy security" is usually defined as the guarantee of a stable and reliable supply of energy at reasonable prices. However, this definition is often misleading because it equates oil supply as the primary focus of a country's energy security ...

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

Advanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

A European carbon border tax: much pain, little gain. Bruegel Policy Contribution Issue n˚5 | March 2020 [PDF]

, 2020
The European Green Deal has set a target of reducing European Union carbon emissions by about 40 percent over the next ten years. Reaching this target is likely to involve a significant increase in carbon prices.
