McGill team develops hybrid membrane that could enable osmotic (blue) energy systems
Osmotic energy also known as blue energy capitalizes on the energy naturally released when two solutions of different salinities mix conditions that occur in countless locations around the world where fresh and salt water meet. The key to capturing blue energy lies in selectively permeable membranes, which allow only one constituent of a saltwater solution to pass through either the water molecules or the dissolved salt ions but not the other.
To date, large-scale blue energy projects such as Norway’s Statkraft’s osmotic power plant at Tofte, Norway, have been impeded by the poor efficiency of existing membrane technology. Statkraft shelved its osmotic effort in 2014, saying that the technology could not be developed within the then current market outlook to become competitive within the foreseeable future.

A recent study published in the journal Astrophysical Journal Letters revealed that the radio signals are now coming at lower frequencies than they had been previously realised. A team of researchers from McGill University researchers and Canada s CHIME Fast Radio Burst has established that FRBs include radio waves at frequencies lower than ever. This latest discovery redraws the boundaries for theoretical astrophysicists who are trying to put their finger on the source of FRBs.
Mystery radio signals coming to us from space deeper than scientists thought
Researchers at McGill University have found that the fast radio bursts located just 500 million light-years away from Earth may be deeper in space, according to a new study

Since fast radio bursts (FRBs) were first discovered over a decade ago, scientists have puzzled over what could be generating these intense flashes of radio waves from outside of our galaxy. In a gradual process of elimination, the field of possible explanations has narrowed as new pieces of information are gathered about FRBs – how long they last, the frequencies of the radio waves detected, and so on.
Now, a team led by McGill University researchers and members of Canada’s CHIME Fast Radio Burst collaboration has established that FRBs include radio waves at frequencies lower than ever detected before, a discovery that redraws the boundaries for theoretical astrophysicists trying to put their finger on the source of FRBs.
