Earth’s inner core may have started slowing spin in 2010 Seismograms confirm Earth’s inner core has slowed its rotation for the first time in decades, possibly beginning in 2010 because of gravitational pull or the liquid iron outer core’s constant motion, which generates the planet’s magnetic field. The slowdown could change the length of a […]
Carbon monoxide (CO) oxidation (2CO + O2 → CO2) on platinum (Pt) group metal surfaces is the model heterogeneous gas/surface catalytic reaction. Pt itself is of the upmost importance as a catalyst for car exhaust cleaning or for the water gas shift reaction, whereas Pt crystal surfaces are model systems for investigating the catalytic CO […]
Scientists have used computational algebraic geometry to study predictions for particle physics experiments, such as those at the Large Hadron Collider (LHC). These experiments, in combination with new mathematical tools, help to solve unanswered questions in physics in a much faster way and have a profound impact on our understanding of nature. When studying particle […]
Any particle accelerator needs a reliable electron or ion source as a first, humble but essential and critical component. The world’s most powerful particle accelerator today -the Large Hadron Collider- extracts its protons from a single bottle of Hydrogen gas. Ion sources produce beams for a large variety of different scientific experiments, industrial processes and […]
Seahenge may have been built to combat climate change Seahenge, an ancient timber monument discovered on an English beach, may have been built to counteract climate deterioration, according to a study in GeoJournal. The research suggests that Seahenge and the nearby Holme II were ritual structures aimed at bringing warmth during periods of severe cold […]
“Helicene” is the name introduced by Newman in 1955, to describe the benzologues of phenanthrene in which the extra ortho -condensed rings give rise to a (regular) cylindrical helix. The pioneer work of Newman in this field cannot be overemphasized; his brillant synthesis and resolution of [6]helicene will remain as a landmark, for it opened […]
The perception of food occurs when food enters the oral cavity and depends on the action of three complementary sensory systems: somesthesia (a group that includes mechanoreception, thermal sensation and nociception), retronasal olfaction and taste. Taste is one of the five classical senses, along with smell, touch, hearing and sight. One of the most common […]
Convenient fast charging and energy density of lithium-ion batteries have long been considered a trade-off, which has hindered the widespread adoption of electric vehicles. A new process will help develop stable, high-energy-density lithium-ion batteries capable of fast charging. A crucial prerequisite for the widespread adoption of electric vehicles (EVs) is the enhancement of lithium-ion battery […]
It is clear that the world began before human beings learned to speak and even long before they made their appearance. However, as far as we are concerned and from our subjective point of view, “everything” began when we were able to articulate our thoughts as a sequence of meaningful words, for it was then […]
