Carbon nanodots do an ultrafine job with in vitro lung tissue

Epidemiological studies have established a strong correlation between inhaling ultrafine particles from incomplete combustion and respiratory and cardiovascular diseases. Still, relatively little is known about the mechanisms ...

Evaluating the contribution of black carbon to climate change

Japanese and US researchers developed an advanced model to assess the ability of black carbon particles to absorb sunlight and contribute to global warming. The model achieved higher sensitivity than obtained by previous ...

Catching ultrafine emissions could help develop cleaner cars

Modern engines—in particular those which inject fuel at high pressure—maximise efficiency and cut carbon dioxide emissions, but may also release harder-to-catch pollution associated with cancers and lung, heart and Alzheimer's ...

How the building blocks of life may form in space

In a laboratory experiment that mimics astrophysical conditions, with cryogenic temperatures in an ultrahigh vacuum, scientists used an electron gun to irradiate thin sheets of ice covered in basic molecules of methane, ammonia ...

New satellite method enables undersea estimates from space

Bigelow Laboratory for Ocean Sciences researchers have developed a statistical method to quantify important ocean measurements from satellite data, publishing their findings in the journal Global Biogeochemical Cycles. The ...

Magnetic liquids improve energy efficiency of buildings

Climate protection and the reduction of carbon dioxide emissions have been on top of global development agendas. Accordingly, research and development projects have been conducted on national and international levels, which ...
