ABSTRACT
Conventional polyalkylene glycols (PAGs) that are derived from the polymerization of ethylene oxide and/or propylene oxide provide many performance benefits such as excellent friction control, good low temperature properties, high viscosity indices and excellent deposit control. One limitation is their poor miscibility in hydrocarbon oils. A new range of oil‐soluble PAG base oils has been developed using butylene oxide as one of the precursors, and these provide superior miscibility in hydrocarbon base stocks. The new base oils offer many of the traditional advantages of PAGs such as high viscosity indices, good low temperature properties and good traction behaviour. In addition, they can be used as a co‐base oil or additive in hydrocarbon base stocks to improve deposit control and provide good film‐forming behaviour. Examples of their structure property relationships will be discussed and also aspects of how this technology may enable application expansion of PAGs in the future.

Vesicle‐Mediated Growth of Tubular Branches and Centimeter‐Long Microtubes from a Single Molecule
Abstract The mechanism by which small molecules assemble into microscale tubular structures in aqueous solution remains poorly understood, particularly when the initial building blocks are non‐amphiphilic molecules and no surfactant is used. It is here shown how a subnanometric molecule ... more
The image illustrates a natural phenomenon of droplet formation caused by the condensation of vapor on a nonwettable surface at temperature below the dew point. Real‐time observing the light scattered from the droplets may lead to a new mechanism for vapor sensing. However, the dew point ... more
NO is a key vasodilator in mammalian cardiovascular systems and has been shown to sensitize tissue to γ‐radiation. However, photochemical NO precursors that can be activated by these NIR wavelengths are extremely limited. G. D. Stucky, D. Zhao, P. C. Ford, F. Zhang and co‐workers have ad ... more
Bioengineers Succeed in Producing Plastic Without the use of Fossil Fuels
A team of pioneering South Korean scientists have succeeded in producing the polymers used for everyday plastics through bioengineering, rather than through the use of fossil fuel based chemicals. This groundbreaking research, which may now allow for the production of environmentally consci ... more
In the past, restoration of paintings and other old artwork often involved application of acrylic resins to consolidate and protect them. One of the most important tasks for modern restorers is thus to remove these layers, because it turns out that acrylic resins not only drastically change ... more
Is trash the solution to tackling climate change?
Converting the trash that fills the world's landfills into biofuel may be the answer to both the growing energy crisis and to tackling carbon emissions, claim scientists in Singapore and Switzerland. New research published in Global Change Biology: Bioenergy, reveals how replacing gasoline ... more
