Formation of flower-like MgO crystal and its effect on the photoluminescence of Mg-cBN ceramics

Microscale flower-like magnesium oxide for highly efficient photocatalytic degradation of organic dyes in aqueous solution

“…6b and S8 (see the ESI †), aer ve cycles, a degradation efficiency as high as 92.2% could still be obtained. In the previous studies, 14,[64][65][66][67][68][69][70][71] although different shapes of micrometer-sized ower-like MgO have also been reported, few 66,68,69 are analogous to the shape of obtained MgO in the current study. Also, their performance had much difference.…”

Hierarchical Structure of Glucosamine Hydrochloride Crystals in Antisolvent Crystallization

“…The micro/nano-spherulitic hierarchical 2,2 ,4,4 ,6,6 -hexanitrostilbene has been fabricated, which is promising to solve the problems of nanoscale energetic materials in agglomeration and microscale bulk crystals in low activity [6]. Materials with hierarchical structures could find broad applications in batteries [8], ceramics [9,10], catalysis [11,12], sensors [13,14], the food industry [15], pharmaceutics [16], etc. For example, when the flower-like SnO 2 nanocrystal was used as the photoanode in dye-sensitized solar cells, the photoelectric conversion efficiency could be largely enhanced [8].…”

“…For example, when the flower-like SnO 2 nanocrystal was used as the photoanode in dye-sensitized solar cells, the photoelectric conversion efficiency could be largely enhanced [8]. Flower-like MgO crystals growing in the face of the ceramics create photoluminescence of Mg-cBN ceramics [9]. Photonic crystals with biological hierarchical structures show tunable optical properties by external stimuli [17].…”
