Temporary glues may not steal headlines, but they can make everyday life easier.


Sticky office notes, bandage strips and painter’s tape are all examples of products that adhere to surfaces but can be removed with relative ease.

There’s only one drawback. To remove any of those adhesives, the glued surfaces need to be pulled apart from each other.

Dartmouth research has discovered a class of molecular materials that can be used to make temporary adhesives that don’t require force for removal. These non-permanent glues won’t be available as home or office supplies, but they can lead to new manufacturing techniques and pharmaceutical design.

“This temporary adhesive works in an entirely different way than other adhesives,” said Katherine

Obama criticizes Americans for liking ‘cheap gas and big cars’ more than ‘the environment’

Former President Barack Obama, in his latest memoir, criticized Americans for liking “cheap gas and big cars” more than they care about “the environment” – even during a catastrophic event like the 2010 Deepwater Horizon oil spill.

The comments came during a section in Obama’s 700-page book, “A Promised Land,” released earlier this month.

On page 570, the former commander in chief recounts a press conference he gave more than a month into the oil spill – now considered one of the largest in history – saying his comments did not adequately express the frustration he truly felt.

“Reading the transcript now, a decade later, I’m struck by how calm and cogent I sound,” Obama writes in his book. “Maybe

Astronomers discover carbon monoxide gas flowing from distant star system

Nov. 30 (UPI) — Scientists have discovered rapid outflow of carbon dioxide emanating from a star system located 400 light-years away.

Astronomers suggest this unique stage of a planetary system could offer scientists fresh insights into the birth and development of our own solar system.

The discovery is scheduled to be presented next week at the Five Years After HL Tau virtual conference. The research has also been accepted for publication in the journal Monthly Notices of the Royal Astronomical Society.

The outflow of carbon dioxide was first spotted during the survey of young “class III” stars by the Atacama Large Millimetre/submillimetre Array in Chile. Some of these young, low-mass stars host debris rings created by the collision of comets, asteroids and planetesimals.

Because the debris from these collisions absorb and reradiate the energy of their host star, these rings can be detected by ALMA.

Around one star, named “NO

Fast-moving gas flowing away from young star caused by icy comet vaporization — ScienceDaily

A unique stage of planetary system evolution has been imaged by astronomers, showing fast-moving carbon monoxide gas flowing away from a star system over 400 light years away, a discovery that provides an opportunity to study how our own solar system developed.

Astronomers have detected fast-moving carbon monoxide gas flowing away from a young, low-mass star: a unique stage of planetary system evolution which may provide insight into how our own solar system evolved and suggests that the way systems develop may be more complicated than previously thought.

Although it remains unclear how the gas is being ejected so fast, the team of researchers, led by the University of Cambridge, believe it may be produced from icy comets being vaporised in the star’s asteroid belt. The results will be presented at the Five Years After HL Tau virtual conference in December.

The detection was made with the Atacama Large Millimetre/submillimetre

DNV GL RP on Quality Assurance of Oil & Gas Digital Twins

DNV GL has published the oil and gas industry’s first recommended practice on how to build and quality-assure digital twins. Developed in collaboration with TechnipFMC, DNVGL-RP-A204 Qualification and assurance of digital twins sets a benchmark for the sector’s varying approaches to building and operating the technology.

It guides industry professionals through

Assessing whether a digital twin will deliver to stakeholders’ expectations from the inception of a project

Establishing confidence in the data and computational models that a digital twin runs on

Evaluating an organization’s readiness to work with and evolve alongside a digital twin.

Seventy-five percent of organizations implementing Internet of Things (IoT) already use digital twins or plan to within a year, according to Gartner. However, there has previously been no commonly agreed methodology for developing and operating the technology among global oil and gas operators and their supply chains.

DNV GL’s RP provides valuable guidance for digital twin

Middle East & Africa Gas Turbine Market Forecast to 2027 – COVID-19 Impact and Regional Analysis By Technology, Capacity, and Application

New York, Nov. 26, 2020 (GLOBE NEWSWIRE) — Reportlinker.com announces the release of the report “Middle East & Africa Gas Turbine Market Forecast to 2027 – COVID-19 Impact and Regional Analysis By Technology, Capacity, and Application” – https://www.reportlinker.com/p05989553/?utm_source=GNW

Gas-fired turbines are faster, more efficient, and less polluting than coal-fired and nuclear power plants.High power-to-weight ratio and low operations pressure are among the various advantages associated with these turbines.

Besides, the gas turbines are durable and efficient, and cheaper to install.They exhibit less downtime and functional failure compared to nuclear and coal-driven turbines.

Increasing demand for natural gas-fired power plants, rising concerns regarding greenhouse gas emissions, and stringent government norms have stimulated the demand for gas turbines.Moreover, governments of the countries in this region offer incentives to companies using natural gas-based turbines for power generation.

In several countries, nuclear power stations have been closed due to political pressure which has led

South Korean scientists find way to extract carbon emissions from exhaust gas

Nov. 23 (UPI) — South Korean researchers say they have developed technology that can draw out carbon dioxide from industrial emissions and convert the climate-warming gas into calcium carbonate, which then can be adapted for different uses.

Koh Dong-yeun and his team at the Korea Advanced Institute of Science and Technology, KAIST, said they have developed a device to convert carbon dioxide into solid materials, which can be used to make cement and other materials, Aju Daily and Yonhap reported Monday.

The statement from KAIST comes two months after Koh and his team published their findings to the online site of ACS Sustainable Chemistry and Engineering, a peer-reviewed journal.

“The technology helps power plants, steel mills and cement makers, which emit a lot of greenhouse gas, to increase their competitiveness by reducing emission and recycling resources,” Koh said, according to Aju Daily.

The scientists said an ultrapermeable membrane is the
