If we are asked what a metal is, most likely we would think almost automatically in those elements that we see as lustrous solids, good conductors of heat and electricity, that tend to form positive ions, and with a particular chemical bond that keep metal atoms in place, the metallic bond. And all of this […]
We live on a planet that is commonly known as the blue planet. This is because more than 70% of its surface is covered by water. However, it is ironic that one of the biggest problems humanity will face in the coming decades is the scarcity of drinking water. Despite the large amount of water […]
Witchcraft involves the use of magic or supernatural powers to harm others. In medieval and early modern Europe, where the term originated, those accused of witchcraft were usually women who were believed to have attacked their own community and often to be in communion with evil beings. Witchcraft powers were acquired by inheritance or initiation […]
Some metals, alloys and transition-element salts exhibit a form of magnetism called antiferromagnetism. This occurs below a certain temperature, named after Louis Néel, when an ordered array of atomic magnetic moments spontaneously forms in which alternate moments have opposite directions. There is therefore no net resultant magnetic moment in the absence of an applied field […]
Human activities impact significantly on the environment we live. The human society has been experiencing extreme weather conditions frequently that indicate a systematic climate shift. Almost every place in the world has set records of extreme temperatures. This trend of extreme weather has been warned by scientists to be possibly a result of excessive human […]

Nanothreads are one-dimensional nanomaterials composed of a primarily sp 3 hydrocarbon backbone, typically formed through the compression of small molecules to high pressures. In 2015, it was found that the slow room-temperature compression of benzene produced crystalline , one-dimensional polymers composed of diamond-like bonds. These diamondoid materials that border nanotubes and polymers are predicted to […]
Twistology could be the study of unexpected changes or developments in stories or situations, from coups d’état to the fatherhood of Darth Vader. In condensed matter physics there is something similar, although the preferred name is twistronics (from twist and electronics). It is understood as the study of how the angle (the twist) between layers […]
Two years of battling COVID-19 has been bad news for tuberculosis (TB) programmes. Respiratory clinicians and researchers have had their time and focus directed elsewhere. And TB has taken advantage. In 2021, the number of TB deaths rose for the first time in over a decade. The barriers caused by lockdowns and overstretched healthcare systems […]
C ardiovascular diseases currently form the most important class of non-contagious diseases and a leading cause of mortality in industrialized nations . Specifically, coronary heart disease is the first cause of death among the cardiovascular diseases . The myocardial infarction (MI), commonly known as a “heart attack”, occurs when blood flow decreases or stops in […]
Inorganic and organic light-emitting diodes (ILEDs and OLEDs, respectively) are quickly replacing incandescent light bulbs and compact fluorescent lamps. The reasons for the success are easy to understand. For instance, ILEDs’ performance has met the market requirements for in-/out-door applications with single-point sources. However, ILEDs cannot be considered a sustainable solution as of today. One […]
