Researchers at Portland State University have developed methods for measuring levels of free-base nicotine in electronic cigarette (e-cigarette) liquids and vapor, the levels of which are associated with harshness upon inhalation of e-cigarette vapors and tobacco smoke.
Purdue researchers have discovered a new two-dimensional material, derived from the rare element tellurium, to make transistors that carry a current better throughout a computer chip.
Without careful management, distributed energy resources have the potential to cause unreliable power delivery, or even outages, and lead utility companies to overcharge customers. A new index will help ISOs and utilities account for uncertainties introduced by both the electricity market and DERs so utility companies can balance the distribution grid and find the fairest customer rates.
A team of researchers in Japan developed a synthetic molecular code to script gene activation. The process, described in the Journal of the American Chemical Society, could help lead to future gene-based therapies for a wide array of diseases.
A study published by Brazilian researchers describes one of Xanthomonas citri's secretion systems and a signaling pathway that enhances its resistance against amoebae. Investigations might contribute for future forms of intervening and putting a stop on the development of X. citri, known for its persistency.
Chemist Vincent Rotello at UMass Amherst, with others at University College London, have developed a 'quick and robust' blood test that can detect liver damage before symptoms appear, offering what they hope is a significant advance in early detection of liver disease. Details appear in Advanced Materials. Their new method can detect liver fibrosis, the first stage of liver scarring that can lead to fatal disease if left unchecked, from a blood sample in 30-45 minutes.
Data hurtle down fiber-optic cables at frequencies of several terahertz. As soon as the data arrive on a PC or television, this speed must be throttled to match the data processing speed of the device components, which currently is in the range of a few hundred gigahertz only. Researchers have now developed a technology that can process the data up to hundred times faster and thus close the gap between the transport and processing speeds.
Victor Lakhno, head of the Laboratory of Quantum-Mechanical Systems of the Institute of Mathematical Problems of Biology, RAS has calculated a critical temperature of the transition, energy, heat capacity and heat of transition of an ideal three-dimensional Bose-condensate of translation-invariant bipolarons (TI-bipolarons). The results obtained offer an explanation of the experiments with high-temperature superconductors.
Molecular switch will facilitate the development of pioneering electro-optical devices
When cells become stressed, they activate specific response patterns. Würzburg researchers have identified new details of these responses, which can help to get a better understanding of neurodegenerative diseases.
