The large aromatic nanoring that wasn’t

The large aromatic nanoring that wasn’t

DIPC Computational and Theoretical Chemistry

By DIPC

Aromaticity is a property of cyclic (ring-shaped), planar (flat) structures with π bonds in resonance (those containing delocalized electrons) that gives increased stability compared to other geometric or connective arrangements with the same set of atoms. Aromatic rings are very stable and do not break apart easily. An aromatic ring contains a set of covalently […]

Early Homo groups once trekked to a well-watered Arabia The Arabian Peninsula was once a green oasis that attracted ancient Homo groups as early as 400,000 years ago during wet periods. Researchers have found evidence of animals migrating to the area’s lakes, rivers and wetlands as well as stone tools. Science News Amputees feel sensations […]

Since the discovery of graphene, a wide diversity of atomic-layer-thick, two-dimensional (2D) materials with varied properties have emerged. Of particular interest are those that exhibit semiconducting behaviour, such as hexagonal boron nitride (hBN). hBN is isoelectronic to graphene and has also a honeycomb lattice formed by alternating nitrogen and boron atoms, but in contrast to […]

Prepared to kill

By Invited Researcher

They were not killed by delinquents who’d had a life of trauma, nor by sadists sunk in the abysses of sex. Their executioners were not barbarians inhabited by notions of genocides, nor slaves to sects that annul reason. They were not killed by the madness that cities sometimes engender. The horror was the handiwork – […]

By DIPC

Over the past several decades researchers have thought how materials and device architectures can efficiently convert solar radiation into electrical power through the photovoltaic effect. Those efforts have led to different methods and processes to produce green energy. In this context, organic photovoltaic (OPV) technology has received considerable attention because it indeed constitutes a new […]

Galaxy photos from Hubble feature merger, 3-armed spiral NASA has released the latest images captured by the Hubble Space Telescope since mission scientists repaired a major computer glitch that hobbled the spacecraft on June 13. The images, which haven’t been colourized, show the merger of a pair of galaxies and an unusual spiral galaxy with […]
