Nanotechnology in South America Market Report

The importance of nanotechnology as a strategic route in developing scientific research and economic growth has been recognized by most South American countries for the last fifteen years. Brazil has very much taken the lead and was investing in the development of nanotechnology as long ago as 2001, followed closely by the other large economies in the region, Mexico and Argentina. These three countries are not just the largest economies in the region but are also those that have a history of adv

Redox Reactions Found to Control Physical Properties of Two-dimensional Materials

Scientists in South Korea have discovered the fundamental principle that gives two-dimensional materials, like graphene, the properties that allow them to work as a next-generation semiconductor, is due to redox reactions. Published this October in the journal Nature Communications, the team from Pohang University of Science and Technology (POSTECH) present their research, outlining their investigations into the oxidation-reduction principle of two-dimensional materials by interfacial diffusion.

Quantum Dot for Nano Fluorescent Semiconductors

Quantum dots have become a principal topic in nanotechnology, finding applications in varying fields, from renewable energy to medical imaging. First created back in the 1980s, the dots are made of tiny, man-made fluorescent semiconductor nanocrystals possessing unique properties. They transport electrons and have interesting optical properties, emitting fluorescent light of various colors stably, determined by the size of the quantum dot. For this reason, these impressive semiconductors have

Nano-Thin Films for Gas Sensors

In the modern world, industrial processes present many pressing environmental issues.
