Observation of Active Sites for Oxygen Reduction Reaction on Nitrogen-doped Multilayer Graphene [PDF]
ACS Nano 8(7), 6856-6862, 2014, 2014 Active sites and catalytic mechanism of nitrogen-doped graphene in oxygen reduction reaction (ORR) have been extensively studied but are still inconclusive, partly due to the lack of an experimental method that can detect the active sites. It is proposed in this report that the active sites on nitrogen-doped graphene can be determined via the ...

Nanostructured Electrodes as Random Arrays of Active Sites: Modeling and Theoretical Characterization [PDF]
Journal of The Electrochemical Society, Electrochemical Society,
2020, 167 (1), pp.013530, 2020 This review presents the main principles underlying the theoretical description of the behavior of regular and random arrays of nanometric active sites. It is further shown how they can be applied for establishing a useful semi-analytical approximation of the arrays responses under diffusion limited conditions when they involve the common situation of ...

Active Sites in Heterogeneous Catalysis [PDF]
, 1977 Publisher Summary This chapter focuses on the active sites in heterogeneous catalysis. The chapter reviews a surface structure and chemisorption characteristics of crystals cut along different crystallographic orientations. A chemical reaction is studied at low pressure to establish correlations between reactivity and surface structure and ...

Reversible adsorption on a random site surface [PDF]
, 2006 We examine the reversible adsorption of hard spheres on a random site surface in which the adsorption sites are uniformly and randomly distributed on a plane. Each site can be occupied by one solute provided that the nearest occupied site is at least one diameter away. We use a numerical method to obtain the adsorption isotherm, i.e.

The electronic structure and geometric structure of nanoclusters as catalytic active sites
Nanotechnology Reviews, 2013 In the past few decades, metal nanoparticles applied in heterogeneous catalysis have attracted extensive attention. The term nanocatalysis is broadly referred to as the unique catalytic effect of this series of materials.

Microscopic origin of light emission in Al_yGa_{1-y}N/GaN superlattice: Band profile and active site [PDF]
PHYSICAL REVIEW B 80, 045311 (2009), 2009 We present first-principles calculations of AlGaN/GaN superlattice, clarifying the microscopic origin of the light emission and revealing the effect of local polarization within the quantum well. Profile of energy band and distributions of electrons and holes demonstrate the existence of a main active site in the well responsible for the main band-edge

Synthesis of the Myoglobin Active Site [PDF]
Proceedings of the National Academy of Sciences, 1973 A simple heme-imidazole compound, having the same geometry as the heme-imidazole complex in myoglobin, has been synthesized. This compound, ferropyrroporphyrin- N -[3-(1-imidazolyl)propyl]amide, reversibly binds oxygen in the solid state or when dissolved in a polystyrene film.

FoxO1 signaling in B cell malignancies and its therapeutic targeting
FEBS Letters, EarlyView.FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.
