Well-controlled 2D squares from conjugated block copolymers
《Science China Chemistry》2018年第11期1345-1346,共2页Pan Zhang Guosong Chen 
Nanoscale two-dimensional （2D） polymer-based platelet structures are of considerable interest for a range of applications [1]. In principle, solution self-assembly of block copolymers （BCPs） provides a convenient ...

Carbon polyhedrons formed by squares and hexagons obeying isolated square rule
《Science China Chemistry》2009年第8期1085-1089,共5页GAN LiHua LIU Jian ZOU Jian LIU ZuoHua LI Li LI BaiZhan TAO ChangYuan 
Supported from Southwest University, China (Grant No. SWNUB2005002);Key Laboratory of the Three Gorges Reservoir Region’s Eco-Environment within Ministry of Education, Chongqing University (Grant No. KLVF-2007-5)
To gain insight into the structures and stability of F4F6 polyhedrons formed by squares and hexagons,a density functional theory study was performed on all isomers of F4F6 polyhedrons with sizes from 8 to 60.The calcu...

A practical approach for near infrared spectral quantitative analysis of complex samples using partial least squares modeling被引量：1
《Science China Chemistry》2009年第7期1021-1027,共7页ZhiChao Liu  Xiang Ma  YaDong Wen  Yi Wang  WenSheng Cai XueGuang Shao 
Supported by the National Natural Science Foundation of China (Grant Nos. 20775036 & 20835002)
The number of latent variables (LVs) or the factor number is a key parameter in PLS modeling to obtain a correct prediction. Although lots of work have been done on this issue, it is still a difficult task to determin...

Outlier detection in near-infrared spectroscopic analysis by using Monte Carlo cross-validation被引量：13
《Science China Chemistry》2008年第8期751-759,共9页LIU ZhiChao CAI WenSheng SHAO XueGuang 
Supported by the National Natural Science Foundation of China (Grant Nos. 20575031 and 20775036);the Ph.D. Programs Foundation of Ministry of Education (MOE) of China (Grant No. 20050055001)
An outlier detection method is proposed for near-infrared spectral analysis. The underlying philosophy of the method is that,in random test(Monte Carlo) cross-validation,the probability of outliers presenting in good ...
