The particle size-dependent processes of structural relaxation and crystal growth in amorphous nifedipine were studied by means of non-isothermal differential scanning calorimetry (DSC) and Raman microscopy. The enthalpy relaxation was described in terms of the Tool-Narayanaswamy-Moynihan model, with the relaxation motions exhibiting the activation energy of 279 kJ·mol for the temperature shift, but with a significantly higher value of ~500 kJ·mol being obtained for the rapid transition from the glassy to the undercooled liquid state (the latter is in agreement with the activation energy of the viscous flow). This may suggest different types of relaxation kinetics manifesting during slow and rapid heating, with only a certain portion of the relaxation motions occurring that are dependent on the parameters of a given temperature range and time frame.

School of Science, Xi'an University of Technology, Xi'an 710048, China.
The rapid complexation of photogenerated electrons-holes with copper (Cu) greatly limits the large-scale application of cuprous oxide (CuO) as a photocatalyst. Therefore, using a hydrothermal method, a type Ⅱ heterojunction structure was constructed by modifying CuO with cerium (IV) oxide (CeO). The CeO/CuO heterojunction photocatalyst effectively increased the photogenerated electron density and reduced the surface transfer impedance.

College & Hospital of Stomatology, Anhui Medical University, Key Lab. of Oral Diseases Research of Anhui Province, No.81, Meishan Road, Shushan District, Hefei City, 230032 China. Electronic address:
Dental fluorosis, as a common chronic fluoride toxicity oral disease, is mainly caused by long-term excessive intake of fluoride, which seriously affects the aesthetics and function of patients' teeth. In recent years, with the rapid development of metabolomics technology, lipidomics, as an important means to study the changes in lipid metabolism in organisms, has shown great potential in revealing the mechanisms of disease development. As a major component of cell membranes and a signaling molecule, metabolic disorders of lipids are closely related to a variety of diseases, but the specific mechanism of action in dental fluorosis is still unclear.
