Yield-height correlation and QTL localization for plant height in two lowland switchgrass populations

ANDERSON, Vijaya G. KAKANI, Michael W. SMITH, Linglong LIU, Hongxu DONG, Dan CHANG

《农业科学与工程前沿（英文）》 2018年第5卷第1期页码 118-128 doi: 10.15302/J-FASE-2018201

摘要： Switchgrass ( L.), as a model herbaceous crop species for bioenergy production, is targeted to improve biomass yield and feedstock quality. Plant height is a major component contributing to biomass yield. Accordingly, the objectives of this research were to analyze phenotypic variation for biomass and plant height and the association between them and to localize associated plant height QTLs. Two lowland switchgrass mapping populations, one selfed and another hybrid population established in the field at Perkins and Stillwater, Oklahoma, were deployed in the experiment for two years post establishment. Large genetic variation existed for plant biomass and height within the two populations. Plant height was positively correlated with biomass yield in the selfed population ( = 0.39, <0.0001) and the hybrid population ( = 0.41, <0.0001). In the selfed population, a joint analysis across all environments revealed 10 QTLs and separate analysis for each environment, collectively revealed 39 QTLs related to plant height. In the hybrid population, the joint analysis across overall environments revealed 35 QTLs and the separate analysis for each environment revealed 38 QTLs. The findings of this research contribute new information about the genetic control for plant height and will be useful for future plant breeding and genetic improvement programs in lowland switchgrass.

Decontamination of mobile phones and electronic devices for health care professionals using a chlorhexidine/carbomer 940® gel

Jancineide Oliveira de Carvalho, Francilio Carvalho Oliveira, Thomas Jay Webster, Fernanda Roberta Marciano, Anderson

《化学科学与工程前沿（英文）》 2019年第13卷第1期页码 192-198 doi: 10.1007/s11705-018-1728-5

摘要： Though they reduce microorganism growth, current hospital disinfectants also damage many of today’s modern electronic devices such as tablets and smartphones. Herein, the efficacy of a new chlorhexidine digluconate gel (CDG) was tested as a disinfectant for mobile and electronic devices in a clinical environment. Specifically, , , and methicillin resistant were used to infect the screen of eight smartphones. The CDG was prepared at concentrations of 2%, 4% and 6%, and tested on paper disks infected with these bacteria before being tested on the smartphones. The devices were disinfected with the CDG gel (4%) at two times: immediately and after 5 min of the bacterial contamination. In all cases, the CDG gel eliminated 100% of gram-positive and gram-negative microorganisms compared to the control (without any agent). In addition, the gel did not damage the smartphones. Therefore, our study suggests that the CDG gel may be applied to disinfect a wide range of electronic devices for health care professionals in the hospital environment.

Recent advances in selective acetylene hydrogenation using palladium containing catalysts

Anderson

《化学科学与工程前沿（英文）》 2015年第9卷第2期页码 142-153 doi: 10.1007/s11705-015-1516-4

摘要： Recent advances with Pd containing catalysts for the selective hydrogenation of acetylene are described. The overview classifies enhancement of catalytic properties for monometallic and bimetallic Pd catalysts. Activity/selectivity of Pd catalysts can be modified by controlling particle shape/morphology or immobilisation on a support which interacts strongly with Pd particles. In both cases enhanced ethylene selectivity is generally associated with modifying ethylene adsorption strength and/or changes to hydride formation. Inorganic and organic selectivity modifiers (i.e., species adsorbed onto Pd particle surface) have also been shown to enhance ethylene selectivity. Inorganic modifiers such as TiO change Pd ensemble size and modify ethylene adsorption strength whereas organic modifiers such as diphenylsulfide are thought to create a surface template effect which favours acetylene adsorption with respect to ethylene. A number of metals and synthetic approaches have been explored to prepare Pd bimetallic catalysts. Examples where enhanced selectivity is observed are generally associated with decreased Pd ensemble size and/or hindering of the ease with which an unselective hydride phase is formed for Pd. A final class of bimetallic catalysts are discussed where Pd is not thought to be the primary reaction site but merely acts as a site where hydrogen dissociation and spillover occurs onto a second metal (Cu or Au) where the reaction takes place more selectively.

摘要：

有机固液废弃物包含大量能量、养分和水分，不应仅视其为废物。数十年来，人们一直对城市固体废物进行回收、堆制和燃烧，并从中提取能量和有价值的物质。污水的首要管理策略是治理和排放。随着技术的进步，通过新方法使利用固体废物和废水成为可能。考虑到废物特殊的化学、物理和生物性质，需要整合多种技术以使废物的能量和价值回收最大化。为此，生物炼制是完全利用废物中的能量和价值的一个合适的方法。研究证明，不可回收废弃物和生物固体可通过不同方法转化为可利用的热能、电能、燃料和化学品，并且液体废物或能帮助农作物和藻类的成长，为能量回收和食物生产提供不同的选择。本文针对有机固液废物提出新型生物炼制方案，这些废物来源于城市废料、食品和生物加工厂以及动物生产设施。四大新型突破性科技——真空辅助高温厌氧消化、扩展鱼菜共生系统、含油废物经甘油裂解制取生物柴油和微波辅助热化学转化，均可运用于生物炼制方案中，从而成功将废物转化，用以生产化学品、化肥、能量（沼气、合成气、生物柴油和生物油）、食物、饲料，得到干净的水并显著减少污染物的排放。

Gold modified cobalt-based Fischer-Tropsch catalysts for conversion of synthesis gas to liquid fuels

Anderson

《化学科学与工程前沿（英文）》 2013年第7卷第3期页码 262-269 doi: 10.1007/s11705-013-1334-5

摘要： The addition of Au as a promoter/modifier for alumina supported Co catalyst has been studied by combined high temperature, high pressure Fourier transform infrared (FTIR) and on-line gas chromatography. The combination of these tools permitted the state of the active catalyst surface to be monitored while following the elution of reaction products during the first 5–7 h on stream of the catalyst. The catalysts under study were a 10%Co/Al O and a 2.5%Au/10%Co/Al O Samples were characterised before use using Raman and temperature programmed reduction (TPR). During the initial stages of reaction, hydrocarbons were built up on the surface of the catalyst as monitored by FTIR and the nature and amount of these species were assessed in terms of CH /CH ratio and the density of these alkyl fragments by employing absorption coefficients for the individual components. The nature and reducibility of the Co particles were modified by the presence of Au while the later also shifted the CO/H balance by acting as an effective water-gas shift catalyst during the early stages of reaction. This characteristic was lost during reaction as a consequence of redistribution of the two metallic phases.

摘要：分析云模型描述不确定性概念的方法和实现定性语意与定量数值相互转换的算法，提出了基于云理论的信任评估模型—信任云。该模型提出云特征参数表达的信任传递和合并算法，在精确描述信任期望值的同时，通过熵和超熵刻画了信任的不确定性。相对于传统的信任评估策略，该模型获取的信任值包含更多的语意信息，更适合作为信任决策的依据。
