TLDR
In this article, the surface states of a solid material that terminate at a surface are considered, and the fundamental limitation has prohibited systematic analysis of surface states is overcome. But the problem is not solved.Abstract:
Surface states—the electronic states found in a solid material that terminate at a surface—are usually vulnerable to contamination and defects. This fundamental limitation has prohibited systematic...read more

Surface Molecule Manipulated Pt/TiO2 Catalysts for Selective Hydrogenation of Cinnamaldehyde
Ran Tao,Bing-Qian Shan,Hao-Di Sun,Meng Ding,Qingsong Xue,Jingang Jiang,Peng Wu,Kun Zhang,Kun Zhang +8 more
TL;DR: In this paper, the authors used selective hydrogenation of cinnamaldehyde(CAL) on platinum-covered titanium oxide (Pt@P25) as a prototype reaction, and showed that the competitive exchange of extra-introduced species (sodium hydroxide and sodium formate) with spontaneously formed weak-bound carbonate and bicarbonate anions at Pt NPs can reconstruct the surface states, which directs the preferred adsorption of the conjugated C=O and C=Cdouble bonds of CAL, and consequently, results in highly efficient synthesis

TL;DR: Efficient reduction of 4-nitrophenol (4-NP) to 4-aminophenol ( 4-AP) in the presence of AuNPs (or AgNPs) and NaBH(4) was observed and was found to depend upon the nanoparticle size or the stem extract concentration used for synthesis.

Ions in water: characterizing the forces that control chemical processes and biological structure.
TL;DR: Two different techniques indicate that the interaction of water with anions is by an approximately linear hydrogen bond, suggesting that the dominant forces on ions in water are short range forces of a chemical nature.
