Chen, Nian-Ke,Li, Xian-Bin,Bang, Junhyeok,Wang, Xue-Peng,Han, Dong,West, Damien,Zhang, Shangbai,Sun, Hong-Bo American Physical Society 2018 Physical review letters Vol.120 No.18

<P>Time-dependent density-functional theory molecular dynamics reveals an unexpected effect of optical excitation in the experimentally observed rhombohedral-to-cubic transition of GeTe. The excitation induces coherent forces along [001], which may be attributed to the unique energy landscape of Peierls-distorted solids. The forces drive the A(lg) optical phonon mode in which Ge and Te move out of phase. Upon damping of the A(1)g mode, phase transition takes place, which involves no atomic diffusion, defect formation, or the nucleation and growth of the cubic phase.</P>

Xiaohu Luo,Bo Chen,Ji Li,Bang Lan,Chenliang Zhou,Zhengxing Ren,Chenggang Ci,Yali Liu 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.124 No.-

Herein, we report a rational design and synthesis of a highly-efficient and eco-friendly glucomannanderivative (GA-2) by the introduction of the thiazole and Schiff base groups into glucomannan (GA). After confirmation of GA-2 by the spectroscopic methods, it was introduced as corrosion inhibitor withexcellent anti-corrosion action for mild steel (MS) in the simulated seawater. As-obtained results revealthat GA-2 has a significantly enhanced anticorrosion performance, and its inhibitive efficiency reaches98.8% at the 0.5 mmol L1 inhibitor concentration, much higher than that of GA (69.8%) and the intermediatederivative GA-1 (81.2%). The significantly enhanced protection performance could be attributed tothe rich S heteroatoms, aromatic rings, and Schiff base groups in the GA-2, which strongly promotes thechemisorption as well as physisorption between GAD and MS. X-ray photoelectron spectroscopy (XPS)results, show that the appearance of N-Fe and S-Fe bonds confirms the strongly anchoring interactionbetween GA and MS. Furthermore, according to the quantum chemical calculations, the results fromthe lowe energy gap and radical distribution function (RDF) analyses further confirm the strongchemisorption of GA-2 at the surface of steel, which illustrates the excellent inhibition performance atthe molecule and atom level.

Golden-leaf privet ( Ligustrum × vicaryi ) is widely used as a horticultural shrub because of its upper golden leaves, butits lower leaves are green. However, the putative mechanisms of its upper golden leaves and the leaf color changes inresponse to light shifts have not been well studied so far. Here, chlorophylls (Chl), carotenoids, and Chl precursors from bothgolden and green leaves grown in full sunlight (approximately 1200 μmol photons m −2 s −1 at noon) or low-light conditions(180 μmol m −2 s −1 ) were determined spectrophotometrically. In addition, their gas exchange parameters and Chl fl uorescencewere measured in situ. Metabolic fl ux analysis of chlorophyll intermediates indicated that the conversion of prochlorophyllideto chlorophyllide was signifi cantly blocked in golden leaves when compared with green leaves. Green leaves showed higherphotosynthetic capacity in low light than golden leaves, but golden leaves presented unexpectedly stronger photosyntheticcapacity and lower reactive oxygen species accumulation under the high-light condition. Furthermore, golden leaves showeda higher level of nonphotochemical quenching (NPQ) after the light-to-dark shift and presented a stronger adaptive abilityto a broad range of light environments. Higher NPQ values and less oxidative damage in golden leaves may be correlatedwith their higher carotenoid levels. The results imply that lower chlorophyll levels and higher carotenoid levels in canopyleaves may help privet plants acclimate better to illumination changes. This study demonstrates the key role of irradiance ingenerating the two types of Ligustrum × vicaryi leaves and sheds a light on cultivation of other ornamental foliage plants.

A high spectral resolution lidar (HSRL) system based on injection-seeded Nd:YAG laser and iodineabsorption filter has been developed for the quantitative measurement of aerosol and cloud. The laserfrequency is stabilized at 80 MHz by a frequency locking system and the absorption line of iodine cellis selected at the 1111 line with 2 GHz width. The observations show that the HSRL can provide verticalprofiles of particle extinction coefficient, backscattering coefficient and lidar ratio for cloud and aerosolup to 12 km altitude, simultaneously. For the measured cases, the lidar ratios are 10~20 sr for cloud,28~37 sr for dust, and 58~70 sr for urban pollution aerosol. It reveals the potential of HSRL to distinguishthe type of aerosol and cloud. Time series measurements are given and demonstrate that the HSRL hasability to continuously observe the aerosol and cloud for day and night

Chronic inflammation is thought to be the leading cause of colorectal cancer, and interleukin-10 (IL10) has been identified as a potent immunomodulatory cytokine that regulates inflammatory responses in the gastrointestinal tract. Although several single nucleotide polymorphisms (SNPs) in IL10 have been associated with the risk of colorectal cancer, their prognostic significance has not been determined. Two hundred and eightytwo colorectal cancer patients were genotyped for two candidate cancer-associated SNPs in IL10. The associations of these SNPs with distant metastasis-free survival and overall survival were evaluated by Kaplan-Meier analysis and Cox regression model. The minor homozygote GG genotype of IL10 rs3021094 was significantly associated with a 3.30-fold higher risk of death compared with the TT+TG genotypes (P = 0.011). The patients with IL10rs3021094 GG genotype also had a poorer overall survival in Kaplan-Meier analysis (log-rank P = 0.007) and in multivariate Cox regression model (P = 0.044) adjusting for age, gender,carcinoembryonic antigen levels, tumor differentiation, stage, lymphovascular invasion,and perineural invasion. In conclusion, our results suggest that IL10 rs3021094 might be a valuable prognostic biomarker for colorectal cancer patients.
