Modeling a model nanoparticle

Metal nanoparticles have a wide range of applications, from medicine to catalysis, from energy to the environment. But the fundamentals of adsorption—the process allowing molecules to bind as a layer to a solid surface—in ...

No assumptions needed to simulate petroleum reservoirs

Hidden deep below our feet, petroleum reservoirs are made up of hydrocarbons like oil and natural gas, stored within porous rock. These systems are particularly interesting to physicists, as they clearly show how temperature ...

Engineered microbe may be key to producing plastic from plants

With a few genetic tweaks, a type of soil bacteria with an appetite for hydrocarbons shows promise as a biological factory for converting a renewable—but frustratingly untapped—bounty into a replacement for ubiquitous ...

North Korea exploring sanctions-proof energy technologies

Power-strapped North Korea is exploring two ambitious alternative energy sources—tidal power and coal-based synthetic fuels—that could greatly improve living standards and reduce its reliance on oil imports and vulnerability ...

Qatar, Exxon Mobil to build $10 bn LNG plant in Texas

Qatar Petroleum and Exxon Mobil announced Tuesday a final decision to build a natural gas export facility in Texas, giving the official green light to a long-discussed project.

Sustainable 'plastics' are on the horizon

A new Tel Aviv University study describes a process to make bioplastic polymers that don't require land or fresh water—resources that are scarce in much of the world. The polymer is derived from microorganisms that feed ...

Petroleum

Petroleum (L. petroleum, from Greek: petra (rock) + Latin: oleum (oil)) or crude oil is a naturally occurring, flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. Petroleum is recovered mostly through oil drilling. This latter stage comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of porosity and permeable structures). It is refined and separated, most easily by boiling point, into a large number of consumer products, from petrol and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals. Petroleum is used in manufacturing a wide variety of materials.
