Greening Under Pressure: Climate Change Exposure and Eco‐Innovation

Business Strategy and the Environment, EarlyView.
ABSTRACT This study explores the impact of climate change exposure on corporate eco‐innovation. Recognizing the urgent need to address climate change, we examine how firms directly respond to climate risks through eco‐innovation. Our findings indicate that climate change exposure is positively associated with corporate eco‐innovation.

Reactivity of Carbohydrate Phosphodiesters, Potential Targets of Antibacterial Agents

Chemistry &Biodiversity, EarlyView.
A simple carbohydrate phosphodiester model was synthesized to compare the reactivity of phosphodiester bonds within carbohydrates and RNA. ABSTRACT While monosaccharide units in bacterial carbohydrates may be linked with phosphodiester bonds, human carbohydrates exclusively contain glycosidic linkages.

Enzymatic Oxidation of Carbohydrate Byproducts for Use in Formation of Chitosan Hydrogels

ChemBioChem, EarlyView.
Carbohydrates, i.e., xylooligosaccharides derived from corn cobs and lactose derived from dairy byproducts, were selectively oxidized using fungal oxidoreductases AbPDH1 (pyranose dehydrogenase from Agaricus bisporus) and FgrGalOx (galactose oxidase from Fusarium graminearum).

通用引物鉴定野鸟源禽流感病毒HA亚型

野生动物学报, 2011
准确、方便快捷的禽流感病毒亚型鉴定方法对于野鸟流感病毒感染与流行状况的调查监测是十分必要的。本研究参照Phipps L P等人建立的通用引物RT-PCR HA亚型鉴定方法,分别对已知为H1、H2、H3、H4、H6和H11亚型的22株野鸟流感病毒毒株以及6株未知亚型的野鸟流感病毒毒株进行了HA亚型分型的验证性试验。即利用1对通用引物对所有病毒样品进行RT-PCR扩增,将各PCR产物进行核苷酸序列测定并与GenBank上参考毒株序列进行同源性比较,以确定其HA亚型。BLAST分析显示 ...

Tuning Potassium Concentration in Empowered Supports for Fischer‐Tropsch Synthesis

ChemCatChem, EarlyView.
Incorporation of potassium into LaAl0.8Mn0.2O3‐δ perovskites (empowered supports) is shown to tune Fischer‐Tropsch (FT) performance. Increasing the potassium content (0–8 at.%) progressively enhances CO conversion up to 2 at.%; above which the catalytic activity enhancement is modest.

Introducing the Cis‐2,3‐Bis(trifluoromethyl)cyclopropyl Chemotype: Late‐Stage Installation and Stereoelectronic Properties

ChemistryEurope, EarlyView.
The cis‐2,3‐bis(trifluoromethyl)cyclopropyl chemotype is introduced. The steric demand of this motif is intermediate between that of the heptafluoroisopropyl and prefluorotertbutyl groups; yet, it induces significantly less lipophilicity than these due to its facial polarity.

Dipolar Molecular Motor Candidates with Planar Chirality

Chemistry – A European Journal, EarlyView.
Two prototypes of molecular motors with simultaneous implementation of planar chirality and a permanent dipole have been designed and synthesized in 7 steps with overall yields of 2.8 to 5.5%. Abstract Two molecular motor candidates built around ruthenium(II) centers featuring both planar chirality and a permanent dipole have been synthesized in seven ...

DNA Noncovalent Interactions of Dinuclear η6‐Arene Ru(II) Complexes: Influence of Complex Charge and Bridging Ligand Length on DNA Binding Mode and Cytotoxic Activity

Chemistry – A European Journal, EarlyView.
A library of cationic dinuclear Ru(II)‐η⁶‐arene analogues was developed to assess how overall charge and Ru–Ru distance influence DNA binding noncovalent interactions and cytotoxicity. NMR studies showed multiple binding modes with the B‐form DNA oligonucleotide d(5΄‐CGCGAATTCGCG‐3΄)2, while the complexes displayed micromolar IC50 values against MCF‐7,

Development of Synthetic Routes to 2′‐O,4′‐C‐Spirocyclopentylene‐Bridged Nucleic Acids: Thymidine, Guanosine, and Adenosine

Chemistry – A European Journal, EarlyView.
A novel synthetic route to 2′‐O,4′‐C‐spirocyclopentylene‐bridged nucleic acid (scpBNA2) monomers bearing thymine, guanine, and adenine nucleobases. The strategy integrates 2′,4′‐lactonization, transglycosylation, and intramolecular iodocyclization, thereby bypassing the 2′‐OH inversion step and providing scpBNA2 nucleoside building blocks for antisense

Electrochemical Characterization of Site‐Specifically Metal‐Modified DNA Films on Gold Electrode Surfaces

ChemPlusChem, EarlyView.
DNA films containing different CuII‐ or AgI‐mediated base pairs are investigated with respect to their electrochemical properties and how these depend on the size and charge of the artificial metal‐binding nucleobase as well as the location of the metal‐mediated base pair within the duplex.
