Correction for 'Electrochromic sensing platform based on steric hindrance effects for CEA detection' by Qingfeng Zhai et al., Analyst, 2016, DOI: 10.1039/c6an00675b.
Catalytic osmylation of cis and trans 2-cyclohexene-cyclohexanol (1a) and (1b) are carried out in the presence of N-methyl morpholine-N-oxide. Under the same conditions, only the cis isomer reacted, leading to triol (3). The steric hindrance of the equatorial OH group probably prevents the trans isomer from entering into such reaction. Triol (3) was also obtained from the reduction of the d...
This paper uses the challenge-hindrance stressor framework to examine impact of challenge and hindrance stressors on police officer staff well-being. Results two studies conducted in English forces demonstrate that relate positively effort enthusiasm individuals invest into their work. Findings also indicate while are associated with exhaustion cross-sectionally (Study 1, N = 469), they do not ...
