“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 […]
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 […]
A team of researchers has invented a more efficient way to extract lithium from waste liquids leached from mining sites, oil fields and used batteries. They demonstrated that a common mineral can adsorb at least five times more lithium than can be collected using previously developed adsorbent materials. The new low-cost high-lithium-uptake process presents the […]
Complementary metal–oxide–semiconductor (CMOS) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions. CMOS technology is used for constructing integrated circuit chips, including microprocessors, microcontrollers, memory chips, and other digital logic circuits. After 50 years of continuous transistor size downscaling and […]
Twisted bilayer and multilayer systems represent two-dimensional materials, where atom-thick layers of the same or different materials are superimposed and rotated by an arbitrary twist angle. Twisted bilayer graphene (TBG) represents arguably the most prominent physical system of this kind, the bilayers of transition metal dichalcogenides (TMD) the other. The effect of twisting two periodic […]
Atomic force microscopy, or AFM, is a widely used technique that can quantitatively map material surfaces in three dimensions, but its accuracy is limited by the size of the microscope’s probe. A new AI technique overcomes this limitation and allows microscopes to resolve material features smaller than the probe’s tip. A new deep learning algorithm […]
Global energy demand is expected to rise around 30% by 2040 according to the International Energy Agency (IEA). Hydrogen (H2) produced by the electrolysis of water, using renewable electricity, the so-called green hydrogen, has emerged as a promising energy vector to respond to this increasing energy demand with the potential to decarbonize transportation, heating, and […]
Digital technologies have gained an essential role in societies’ development, by generating a global transformation in economic, social, and environmental dimensions. Digitalization does not just bring comfort and effectiveness in daily life but also contributes to equity and opportunities generation. However, this digital transformation is raising a fierce debate on how to ensure a positive […]
The climate crisis arising from greenhouse gas emissions has led to a greater emphasis on energy security, and affordability, to ensure a smooth energy transition. The decarbonization of the energy sector will promote a reduction in carbon emissions and will minimize catastrophic natural disasters. The deployment of low-carbon technology towards a sustainable and clean energy […]

Sensors are essential tools for detecting and analysing trace molecules in a variety of fields, including environmental monitoring, food safety, and public health. However, developing sensors with high enough sensitivity to detect these tiny amounts of molecules remains a challenge. One promising approach is surface-enhanced infrared absorption (SEIRA), which uses plasmonic nanostructures to amplify the […]
