Diversity-oriented synthesis of blue emissive nitrogen heterocycles and their conjugation with carbon

Viviana Maffeis, Lisa Moni, Daniele Di Stefano, Silvia Giordani, Renata Riva

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 1,   Pages 76-89 doi: 10.1007/s11705-019-1833-0

Abstract: The search for new fluorescent molecules for possible applications as functional -electron systems and their conjugation with different nanomaterials is nowadays of paramount importance to broaden the availability of materials with different properties. Herein we present a diversity-oriented approach to heterocyclic luminophores based on a multicomponent Ugi reaction followed by a Pd-mediated cascade sequence. The new molecules are coupled to carbon nano-onions, and hybrid systems represent the first example of blue emitters conjugated with these carbon nanoparticles.

Fluoroalcohol-mediated reductive iodonio-Claisen rearrangement: Synthesis of complex

Hem Raj Khatri,Hai Nguyen,James K. Dunaway,Jianglong Zhu

Frontiers of Chemical Science and Engineering 2015, Volume 9, Issue 3,   Pages 359-368 doi: 10.1007/s11705-015-1530-6

Abstract: Reductive iodonio-Claisen rearrangement (RICR) involving -iodanes and allyl or substituted-allyl silanes in fluoroalcohols, such as 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) and 2,2,2-trifluoroethanol (TFE), was studied for the synthesis of complex -allyl or substituted-allyl iodoarenes. In comparison to the previously reported condition involving boron trifluoride diethyl etherate, the RICR mediated by fluoroalcohols was found to proceed more effectively. The resulting complex -allyl iodoarenes are useful synthetic intermediates and can be readily converted to various heterocyclic compounds.

Automatic risk identification and safety early-warning of underground construction under complex conditions

Ding Lieyun,Zhou Cheng

Strategic Study of CAE 2012, Volume 14, Issue 12,   Pages 85-93

Abstract:

One of the most important problems in safety management of metro construction is the insufficient collection and usage of construction safety information, so that the safety control of metro construction is still “in the black box”. Therefore, the presented research applies information technology to safety control of metro construction, which includes: a. For safety risk identification before construction, we proposed a novel approach to automatically identify construction safety risk out of engineering drawings with information technology. Then the safety knowledge of metro construction could be accumulating, sharing and reusing more accurate and effective. b. For risk early-warning during construction, we brought up an approach based on safety risk information fusion and temporal-spatial coupling for metro construction, which is able to effectively identify and track dangerous construction process and locations dynamically. c. For special sections of high risk, we developed the integrated control techniques of automatic monitoring and real-time early-warning for metro construction. The system send any early-warning information to construction workers on site, so that controlling methods and emergency moves can be applied in real time to ensure construction safety. The research achievements are successfully applied in the metro construction in Wuhan, Shenyang, Kunming, Zhengzhou, etc. in China.

Research of the Preparation Technology for Zr66Al9Cu16Ni9 Bulk Amorphous Alloy

Ruan Xuping,Ruan Hongwei

Strategic Study of CAE 2004, Volume 6, Issue 5,   Pages 76-78

Abstract:

The paper introduced the preparation technology for bulk amorphous alloys. The samples were prepared by using the vacuum arc furnace, and the melt was processed by three different methods. The crystalloids of the samples were analyzed by using X - ray diffraction technology. The results showed that the compound oxide glass composed of B2O3 and Na2SiO3 reacted with some elements in the melt, therefore, it wasn´t favourable for coating the Zr66Al9Ni9Cu16 alloy, hence hindering the formation of the amorphous state. The fluorides composed of CaF2(45%), A1F3(50% ) and CaO (5%) and frace Ti02 reacted with some elements in the melt, so they were not suitable for purifying the Zr66Al9Ni9Cu16 alloy. High vacuum degree of equipment and high purity of the raw and processed materials were the important factors for to promoting the melt to form the amorphous alloy.
