Recently, a Chinese research team from Hefei Institutes of Physical Science reported the synthesis of graphene quantum dots (GQDs) under an external high magnetic field (HMF) and their applications in photothermal therapy (PTT). By introducing HMF during the preparation of GQDs, the joint team used phenol molecules as single precursors and hydrogen peroxide as oxidant, and the resulting 9T-GQDs were expected to possess strong absorbance in NIR-II region for improvement of their applications in PTT.
Researchers from the Institute of Modern Physics (IMP) have made progress in the study of enzymatic hydrolysis process of alkali pretreated straw lately. The research provides insight into the structural changes and visualization of the hydrolysis process.
Since the discovery of quasars more than half a century ago, measuring their distances has always been a fundamental problem for cosmology. Recently, a team led by Prof. WANG Jianmin from the Institute of High Energy Physics used a new geometric method developed by the team to successfully measure the cosmological distance to the first identified quasar 3C 273.
A research team led by Prof. HUANG Xingjiu in Institute of Intelligent Machines (IIM), Hefei Institutes of Physical Science, explored phase-dependent electrochemical stripping performance of FeOOH nanorod.
PtSe2, one of typical group-10 transition metal dichalcogenides (TMDCs), undergoes a dramatical bandgap shrinking from an indirect bandgap semiconductor for monolayer to a semimetal for bulk. Recently, a study led by Prof. WANG Jun from Shanghai Institute of Optics and Fine Mechanics reported the real-time observation of the interlayer lattice vibrations in bilayer and few-layer PtSe2 in time domain by means of the coherent phonon method.
A research group led by Prof. TANG Jie from Xi'an Institute of Optics and Precision Mechanics (XIOPM) demonstrated a new V–I characteristic modulation enhanced plasma approach in a non-self-sustained discharge, based on which a high-performance laminar plasma jet array (LPJA) with its width up to 90 mm is developed.
