Method for preparing an at least partially acetal-protected sugar

Jeremy Luterbacher, Songlan Sun, Lorenz Perry Manker, Anastasiia Komarova

The present invention relates to a method for preparing an at least partially acetal-protected sugar involving the step of reacting a sugar or a sugar derivative selected from the group consisting of an aldopentose, an aldohexose, an aldopentoside and an a ...

Anionic character of the conduction band of sodium chloride

Klaus Kern, Abhishek Grewal

The alkali halides are ionic compounds. Each alkali atom donates an electron to a halogen atom, leading to ions with full shells. The valence band is mainly located on halogen atoms, while, in a traditional picture, the conduction band is mainly located on ...

High Aspect Ratio Au Microflakes via Gap-Assisted Synthesis

Giulia Tagliabue, Fateme Kiani Shahvandi

Ultrathin and extra-large single-crystalline Au microflakes (Au MFs) have a huge potential in applications ranging from nanophotonics to catalysis. Yet, wet chemical synthesis approaches cannot access this size range due to the proportionality between grow ...

AMER CHEMICAL SOC2022

Although important for atmospheric processes and gas-phase catalysis, very little is known about the hydration state of ions in the vapor phase. Here we study the evaporation energetics and kinetics of a chloride ion from liquid water by molecular dynamics ...

Layered Hybrid Formamidinium Lead Iodide Perovskites: Challenges and Opportunities

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jovana Milic

Hybrid halide perovskite materials have become one of the leading candidates for various optoelectronic applications. They are based on organic-inorganic structures defined by the AMX(3) composition, were A is the central cation that can be either organic ...

AMER CHEMICAL SOC2021

A series of Cu(diimine)(X-sal)(NO3) complexes, where the diimine is either 2,2'-bipyridine (bpy) or 1,10-phenanthroline (phen) and X-sal is a monoanionic halogenated salicylaldehyde (X = Cl, Br, I, or H), have been synthesized and characterized by elementa ...

Postpassivation of Multication Perovskite with Rubidium Butyrate

Ulf Anders Hagfeldt, Rodrigo Szostak

Many multication perovskites for highly stable and efficient solar cells benefit from rubidium iodide introduced in the precursor solution. It is well-known that Rb+ influences positively the optoelectronic and mobility properties and has a direct effect u ...

AMER CHEMICAL SOC2020

We present here first principles hybrid functional calculations of the atomic and electronic structure of several iodine-related point defects in CsPbI3, a material relevant for photovoltaic applications. We show that the presence of neutral interstitial I ...
