Particulate-bound alkyl nitrate pollution and formation mechanisms in Beijing, China [PDF]
Atmospheric Chemistry and PhysicsFine particulate matter (PM2.5) samples were collected between November 2020 and October 2021 at the Minzu University of China in Beijing, and the n-alkyl nitrate concentrations in the PM2.5 samples were determined to investigate n-alkyl nitrate ...

Modelling structure and ionic diffusion in a class of ionic liquid crystal-based solid electrolytes [PDF]
, 2023 Next-generation high-efficiency Li-ion batteries require an electrolyte that is both safe and thermally stable. A possible choice for high performance all-solid-state Li-ion batteries is a liquid crystal, which possesses properties in-between crystalline solids and isotropic liquids.

Controlling the Morphology of Aggregates of an Amphiphilic Synthetic Receptor through Host-Guest Interactions [PDF]
, 2006 A new amphiphilic receptor containing a macrocyclic anionic headgroup and a single alkyl chain was prepared through an efficient templated synthesis. The interdependence of the aggregation behavior and the host-guest chemistry was studied. In the absence

Ni/Co-Catalyzed Homo-Coupling of Alkyl Tosylates
Molecules, 2019 A direct reductive homo-coupling of alkyl tosylates has been developed by employing a combination of nickel and nucleophilic cobalt catalysts. A single-electron-transfer-type oxidative addition is a pivotal process in the well-established nickel ...

Surface Dipoles and Work Functions of Alkylthiolates and Fluorinated Alkylthiolates on Au(111) [PDF]
J. Phys. Chem. B 2006, 110, 22628-22634, 2006 We study the dipole formation at the surface formed by -CH3 and -CF3 terminated shortchain alkyl-thiolate monolayers on Au(111). In particular, we monitor the change in work function upon chemisorption using density functional theory calculations. We separate the surface dipole into two contributions, resulting from the gold-adsorbate interaction and ...

How do electronic carriers cross Si-bound alkyl monolayers? [PDF]
, 2005 Electron transport through Si-C bound alkyl chains, sandwiched between n-Si and Hg, is characterized by two distinct types of barriers, each dominating in a different voltage range. At low voltage, current depends strongly on temperature but not on molecular length, suggesting transport by thermionic emission over a barrier in the Si. At higher voltage,

Tunneling transport in devices with semiconducting leads [PDF]
Phys. Rev. B 81, 085307 (2010), 2009 This paper extends the modern theory of tunneling transport to finite temperatures. The extension enables applications to molecular electronic devices connected to semiconducting leads. The paper presents an application of the theory to molecular devices made of alkyl chains connected to silicon nano-wires, mapping their transport characteristics as ...
