Hefei Institutes of Physical Science had compiled and published a book titled Environmental Optics and Technology that summarizes the achievements of environmental optical monitoring technology, the self-developed three-dimensional monitoring system, and its application.
Some doped semiconductor, such as nonstoichiometric copper chalcogenides and oxygen-deficient metal oxides, showed surface plasmon resonance (SPR) effect, which usually existed in noble metal nanostructures. These materials are welcomed for their low cost. However, the optical response range of plasmonic semiconductor materials was mostly in the infrared region, which is not efficient for utilization of solar energy.
Two-dimensional (2D) ferroelectric materials (FEMs) and their application in ferroelectric tunnel junctions (FTJs) have attracted much attention. But the way to better integrate with the present semiconductor technology remains secret.
A research group led by Prof. ZANG Haimin from the Institute of Solid State Physics, Hefei Institutes of Physical Science reported inactivation and regeneration of highly ordered Nb2O5 nanochannel film catalyst for electrocatalytic N2 reduction.
H2S is one of the most common toxic contaminants frequently utilized in various fields, including the oil, gas, waste treatment, and paper industries. Even trace amounts of H2S gas are extremely toxic to many organisms, such as human respiratory and nerve systems. Generally, it is recommended that the acceptable ambient levels of H2S for a healthy condition are in the range of 20 -100 ppb.
