Can cobalt nanoparticles replace platinum?

Platinum works well as a catalyst in hydrogen fuel cells, but it has at least two drawbacks: It is expensive, and it degrades over time. Brown chemists have engineered a cheaper and more durable catalyst using graphene, cobalt, and cobalt-oxide — the best nonplatinum catalyst yet. Their report appears in the journal Angewandte Chemie International Edition.   Original post on brown.edu    Comments on reddit.com   

Sentences put on hold over Mass. drug lab scandal

BOSTON (AP) — One at a time, the prison inmates sat down at a wooden table, linked by videoconference to a Boston courtroom, where their attorneys and prosecutors explained the role a disgraced chemist played in their criminal cases. The fallout from a scandal at a state drug lab played out in court Monday, as Judge Christine McEvoy began hearing what is expected to be nearly 200 legal challenges in Suffolk Superior Court drug cases. The chemist, Annie Dookhan, 34, of Franklin, has been charged with obstruction of justice and accused of skirting protocols and faking tests results at a former Department of Public Health lab. The Boston lab was closed by state police in August after Dookhan told them she had faked test results, forged paperwork and sometimes mixed samples. During the morning session, McEvoy granted defense motions to place sentences on hold and set bail for about 10 inmates now serving time at the state prison in Norfolk. Anthony Benedetti, chief counsel for the Committee for Public Counsel Services, which represents indigent defendants, said he objects to that description, saying many are low-level nonviolent offenders and others might be innocent.   Original post on sfgate.com    Comments on reddit.com   

Envelope for an artificial cell

(PhysOrg.com) — Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life.   Original post on physorg.com    Comments on reddit.com    Other physorg.com posts    Other posts in Science
