• Graphene foam detects explosives, emissions better than today's gas sensors
  

  A new study from Rensselaer Polytechnic Institute demonstrates how graphene foam can outperform leading commercial gas sensors in detecting potentially dangerous and explosive chemicals. The discovery opens the door for a new generation of gas sensors to be used by bomb squads, law enforcement offic more

• Graphene: Singles and the few

  A timely review analyzing the correlation of synthesis methods and physical properties of single-layer and few-layered graphene flakes. A review of methods used for synthesizing both single and few-layer graphene and the resulting properties is presented by C.N.R. Rao and colleagues at the Jawaharla more

• Burn injuries under freezing (labor protection) conditions?
  

  "A little splash of liquid nitrogen hasn't hurt anybody" - this happens to be a widespread opinion in many laboratories. The real dangers connected to cryogenic gases many people had to learn firsthand, unexpected and painful. Skin irritation, cell and tissue damage or severe burn injuries may occur, depending on the type of contact and exposure time. There are less possibilities of medical treatment than for injuries caused by influence of heat more

• LOOXSTER® concentrates bacterial DNA
  

  Detection of the bacterial content of a specific sample, irrelevant from its source, is not as straightforward as it seems. In clinical microbiology laboratories, the gold standard method for the detection of pathogens in patients suspected of systemic infections is the blood culture. However, this technique is known to have many drawbacks especially with regard to patient's antibiotics treatment, low abundance and non-cultivable organisms. Moreover, it takes usually 3 to 5 days to obtain a result from blood culture which is too late to initiate proper antibiotic therapy. Amplification-based methods such as PCR allow results in a more rapid fashion. However, their sensitivity, to date, are no better, and sometimes worse, than culture-based methods. more

• Reaching the Next Level of Microwave-assisted Organic Synthesis

  Microwave-assisted organic synthesis (MAOS) has become an increasingly popular discipline in modern chemical method development. At first, reaction optimization and method development on a small scale were the main areas of interest in MAOS. However, the growing acceptance and success of this innovative microwave technology revealed the necessity for large-scale synthesis of valuable compounds using microwave heating, especially in industrial laboratories more
