Mechanisms of Ketone/Imine Hydrogenation Catalyzed by Transition-Metal Complexes

引用

Energy & Environmental Materials 2019年第4期2卷 292-312页

Alcohols and amines are important in pharmaceutical, perfume, and agrochemical industries. Catalytic asymmetric synthesis is one of the major ways to produce chiral alcohols/amines from prochiral ketones/imines via hydrogenation. Meanwhile, the alcohol/amine dehydrogenation with high hydrogen energy density is paid more and more attention as promising hydrogen-storage media. In this review, we summarize classifications of mechanisms of ketone/imine hydrogenation and alcohol/amine dehydrogenation catalyzed by transition-metal (TM) complexes, the H2activation modes, and the nature of asymmetric ketone/imine hydrogenation (AKH/AIH). This will elaborate our understanding on the nature of the TM-catalyzed ketone/imine hydrogenation and alcohol/amine dehydrogenation reactions.

AIM:To evaluate the association of the autophagy- related 16-like 1 (ATG16L1 ) T300A polymorphism (rs2241880) with predisposition to inflammatory bowel diseases (IBD) by means of ***: Publications addressing the relationship between rs2241880/T300A polymorphism of ATG16L1 and Crohn's disease (CD) and ulcerative colitis (UC) were selected from the MEDlinE and EMBASE data-bases. To make direct comparisons between the data collected in these studies, the individual authors were contacted when necessary to generate a standardized set of data from these studies. From these data, odds ratio (OR) with 95% confidence interval (CI) were ***: Twenty-five studies of CD were analyzed, 14 of which involved cases of UC. The variant G allele of ATG16L1 was positively associated with CD (OR=1.32, 95% CI: 1.26-1.39, P<0.00001) and UC (OR =1.06, 95% CI:1.01-1.10, P=0.02). For child-onset IBD, a higher G allele frequency was found for cases of CD (OR=1.35, 95% CI: 1.16-1.57, P=0.0001) than for cases of UC (OR = 0.98, 95% CI: 0.81-1.19, P = 0.84) relative to ***: The ATG16L1 T300A polymorphism contributes to susceptibility to CD and UC in adults, but different in children, which implicates a role for autophagy in the pathogenesis of IBD.

Development of N-doped carbons from zeolite-templating route as potential electrode materials for symmetric supercapacitors

引用

International Journal of Minerals,Metallurgy and Materials 2018年第12期25卷 1482-1492页

作者： Meng Ren Cheng-yun Zhang yue-lin Wang Jin-jun Cai Hunan Key Laboratory of Environment Friendly Chemical Process Technology School of Chemical Engineering Xiangtan University State Key Laboratory of Powder Metallurgy Central South University School of Engineering Materials & Science Queen Mary University of London

N-doped carbons were fabricated from zeolite-templated carbon via modification with melamine and mild KOH activation. The N-doping treatment and KOH activation slightly lowered the surface areas of pristine zeolite-templated carbon; nonetheless, N-doped carbons with a lower surface area exhibited much higher capacitance and cycling stability as fabricated into symmetric supercapacitor. Significantly, N-doped carbon obtained at 700°C showed a capacitance of 45.7 F/g at 0.1 A/g and 42.0 F/g at 10 A/g for the fabricated supercapacitor with 6 M KOH electrolyte, with 92% retention of initial capacitance as current density increased up to 100-fold. This performance was attributed to the dual contribution of electric double-layer capacitance and pseudo-capacitance. The assembled supercapacitor also exhibited excellent cycling stability, with 91% capacitance retention at 10 A/g after 10000 cycles.

Design and simulation of a tuning fork micromachined gyroscope with slide film damping

引用

光学精密工程 2005年第5期13卷 519-524页

作者： CHE Lu-feng XIONG Bin JIAO Ji-wei WANG yue-lin State Key Laboratory of Transducer Technology Shanghai Institute of Microsystem and Information Technology Chinese Academy of Sciences Shanghai 200050 China

A novel tuning fork micromachined gyroscope, based on slide-film damping, is presented. The electrostatic driving gyroscope consists of two driving masses each of which supports one sensitive mass. The angular rate is sensed by the differential capacitances consisted of movable bar electrodes and fixed bar electrodes located on the glass wafer. The gyroscope can operate at atmospheric pressure with slide film damping in the driving and sensing directions, eliminate vacuum packaging and restrain cross-axis acceleration signal. The results of design and simulation show that the driving and sensing mode frequencies are 3 106 Hz and 3 175 Hz,respectively, and the Q-values in driving and sensitive modes are 1 721 and 1 450 respectively. The design resolution is 0.025°/s.

Behavioral interventions to eliminate fear responses

引用

Science China(Life Sciences) 2018年第6期61卷 625-632页

Fear memory underlies anxiety-related disorders, including posttraumatic stress disorder(PTSD). PTSD is a fear-based disorder,characterized by difficulties in extinguishing the learned fear response and maintaining extinction. Currently, the first-line treatment for PTSD is exposure therapy, which forms an extinction memory to compete with the original fear memory. However,the extinguished fear often returns under numerous circumstances, suggesting that novel methods are needed to eliminate fear memory or facilitate extinction memory. This review discusses research that targeted extinction and reconsolidation to manipulate fear memory. Recent studies indicate that sleep is an active state that can regulate memory processes. We also discuss the influence of sleep on fear memory. For each manipulation, we briefly summarize the neural mechanisms that have been identified in human studies. Finally, we highlight potential limitations and future directions in the field to better translate existing interventions to clinical settings.

BACKGROUND Colonic lipomas are rare, slow-growing benign tumors. Colonic lipomas are generally asymptomatic and are found incidentally. Although cases of cecal lipoma have been sporadically reported in the literature, the disease has not been systematically *** SUMMARY We present a 44-year-old man who underwent a routine physical check-up during which colonoscopic examination revealed an asymptomatic 1.5-cm cecal mass at the appendiceal orifice. Laparoscopic exploration was performed that also demonstrated a congested and erythematous appendix. En bloc resection of both the cecum and vermiform appendix was performed because of the suspicion of malignancy. Histopathological examination revealed a cecal lipoma composed of mature adipose tissue, and the appendix showed subclinical *** procedures and findings were discussed, along with relevant English literature that was retrieved from the PubMed database from 2000 to ***-six cases, including ours, were reported. Consistent with the findings of the literature, it is difficult to obtain a definitive diagnosis by colonoscopic *** Surgery remains the treatment of choice for this condition. Intraoperative frozen pathological sectioning helped the surgeon decide the extent of surgery, and radical surgery was avoided. Excision of benign lesions occupying the appendiceal orifice may be indicated for the prevention of later development of acute appendicitis. The prognosis is generally good, with only one of the 26 reported patients complicated with acute appendicitis, who subsequently succumbed due to severe comorbidities and sepsis.

Chinese Physics B 2022年第3期31卷 140-145页

作者： Jian-Wen Wu yue-Jin Cai Ji lin Department of Physics Zhejiang Noimal UniversityJinhua 321004China

With the aid of the Painlevé analysis, we obtain residual symmetries for a new(3+1)-dimensional generalized Kadomtsev–Petviashvili(gKP) equation. The residual symmetry is localized and the finite transformation is proposed by introducing suitable auxiliary variables. In addition, the interaction solutions of the(3+1)-dimensional gKP equation are constructed via the consistent Riccati expansion method. Particularly, some analytical soliton-cnoidal interaction solutions are discussed in graphical way.
