Published Why natural gas is not a bridge technology
(via sciencedaily.com) The expansion of natural gas infrastructure jeopardizes energy transition, as natural gas is not a bridge technology towards a 100 per cent renewable energy system as defined by the Paris Climate Agreement. The researchers have examined the natural gas issue from five perspectives and given gas a fairly poor climate balance, comparable to that of coal or oil. They recommend that politicians and scientists revise the current assumptions about natural gas.
Published Bacteria for blastoff: Using microbes to make supercharged new rocket fuel
(via sciencedaily.com) Biofuel scientists used an oddball molecule made by bacteria to develop a new class of sustainable biofuels powerful enough to launch rockets. The candidate molecules have greater projected energy density than any petroleum product, including the leading aviation and rocket fuels, JetA and RP-1.
Published Reaction insights help make sustainable liquid fuels
(via sciencedaily.com) Methanol made from CO2 in the air can be transformed into carbon neutral fuels. A new mechanistic understanding aids development of this sustainable alternative.
Published Radio waves for the detection of hardware tampering
(via sciencedaily.com) Up to now, protecting hardware against manipulation has been a laborious business: expensive, and only possible on a small scale. And yet, two simple antennas might do the trick.
Published Earth-abundant solar pixels found to produce hydrogen for weeks
(via sciencedaily.com) Devices made of readily available oxide and carbon-based materials can produce clean hydrogen from water over weeks -- according to new research. The findings could help overcome one of the key issues in solar fuel production, where current earth-abundant light-absorbing materials are limited through either their performance or stability.
Published Secure communication with light particles
(via sciencedaily.com) While quantum computers offer many novel possibilities, they also pose a threat to internet security since these supercomputers make common encryption methods vulnerable. Based on the so-called quantum key distribution, researchers have developed a new, tap-proof communication network.
Published Emulating impossible 'unipolar' laser pulses paves the way for processing quantum information
(via sciencedaily.com) A laser pulse that sidesteps the inherent symmetry of light waves could manipulate quantum information, potentially bringing us closer to room temperature quantum computing.
Published Hydrogen production method opens up clean energy possibilities
(via sciencedaily.com) A new energy-efficient way to produce hydrogen gas from ethanol and water has the potential to make clean hydrogen fuel a more viable alternative for gasoline to power cars.
Published Scientists show how to store liquid fuels in polymeric gels to prevent explosions and fires
(via sciencedaily.com) Liquid fuels with high energy density, though used worldwide, are dangerous to transport and store owing to their volatility, which produces explosive gas mixtures. To address this problem, researchers recently investigated the possibility of storing liquid fuel within polymeric gel networks, preventing their fast evaporation, and demonstrating good combustion performance. Their work paves the way for safer transport and storage of liquid fuels.
Published Confirmed: Atmospheric helium levels are rising
(via sciencedaily.com) Scientists used an unprecedented technique to detect that levels of helium are rising in the atmosphere, resolving an issue that has lingered among atmospheric chemists for decades.
Published Self-propelled, endlessly programmable artificial cilia
(via sciencedaily.com) Researchers have developed a single-material, single-stimuli microstructure that can outmaneuver even living cilia. These programmable, micron-scale structures could be used for a range of applications, including soft robotics, biocompatible medical devices, and even dynamic information encryption.
Published Scientific advance leads to a new tool in the fight against hackers
(via sciencedaily.com) A new form of security identification could soon see the light of day and help us protect our data from hackers and cybercriminals. Quantum mathematicians have solved a mathematical riddle that allows for a person's geographical location to be used as a personal ID that is secure against even the most advanced cyber attacks.
Published Lignin-based jet fuel packs more power for less pollution
(via sciencedaily.com) An experimental plant-based jet fuel could increase engine performance and efficiency, while dispensing with aromatics, the pollution-causing compounds added to conventional fuels, according to new research.
Published Cheaper hydrogen fuel cell could mean better green energy options
(via sciencedaily.com) Researchers have developed a hydrogen fuel cell that uses iron instead of rare and costly platinum, enabling greater use of the technology.
Published Extract from a common kitchen spice could be key to greener, more efficient fuel cells
(via sciencedaily.com) Researchers have discovered a novel way to combine curcumin -- the substance in turmeric -- and gold nanoparticles to create an electrode that requires 100 times less energy to efficiently convert ethanol into electricity.
Published What is causing the rise in black lung disease?
(via sciencedaily.com) Silica exposure is a driving force behind rising rates of coal workers' pneumoconiosis, according to a new study that compared the pathology and mineralogy of the disease across generations. The study offers scientific evidence explaining why progressive massive fibrosis, the most severe form of black lung disease, is occurring more frequently and among younger coal workers in West Virginia, Virginia and Kentucky.
Published New technique offers faster security for non-volatile memory tech
(via sciencedaily.com) Researchers have developed a technique that leverages hardware and software to improve file system security for next-generation memory technologies called non-volatile memories (NVMs). The new encryption technique also permits faster performance than existing software security technologies.
Published Technology has the potential to change the patient-provider relationship
(via sciencedaily.com) As personal health records (AKA patient portals) allowing patients to see test results, medications and other health information gain in popularity, scientists studied cancer patients' and doctors' differing perceptions of this tool. Patients cited potential for personal health records to deepen their relationship with their healthcare provider and to allow them to be more understood. Physicians were interested in having more clinical information sharing to facilitate better patient care.
Published Scavenger nanoparticles could make fuel cell-powered vehicles a reality
(via sciencedaily.com) Engineers have developed a material that could give fuel cell systems a competitive edge over the battery systems that currently power most electric vehicles.
Published New method purifies hydrogen from heavy carbon monoxide mixtures
(via sciencedaily.com) Refining metals, manufacturing fertilizers and powering fuel cells for heavy vehicles are all processes that require purified hydrogen. But purifying, or separating, that hydrogen from a mix of other gases can be difficult, with several steps. Chemical engineers have now demonstrated that the process can be simplified using a pump outfitted with newly developed membrane materials.
