Using In Situ TEM to Understand the Surfaces of Electrocatalysts at Reaction Conditions: Single‐Atoms to Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
This review summarizes recent advances in closed‐cell in situ TEM strategies for accurate determination of the activity and stability of single‐atom catalyst systems during operation. Operando conditions causing dynamic changes of SAC systems are highlighted and we explain why ensemble average‐based optical techniques may benefit from the technological

Implementing the one-dimensional quantum (Hadamard) walk using a Bose-Einstein Condensate

open access: yes, 2006
We propose a scheme to implement the simplest and best-studied version of quantum random walk, the discrete Hadamard walk, in one dimension using coherent macroscopic sample of ultracold atoms, Bose-Einstein condensate (BEC).

On some classes of almost periodic functions in abstract spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We deal with C(n)-almost periodic functions taking values in a Banach space. We give several properties of such functions, in particular, we investigate their behavior in view of differentiation as well as integration.

Noncommutative superpositions for nonlinear operators

open access: yesJournal of Mathematical Analysis and Applications, 1970
AbstractLet T be an operator, T: D → E, T has a superposition with respect to an element e ϵ E iff ∃ a binary operation ∗ on D such that T(x ∗ y) = e when T(x) = T(y) = e.All operators having a superposition found until now have commutative superposition operations.

Generalized spectroscopy; coherence, superposition, and loss [PDF]

open access: yes, 2007
We analyze single particle coherence and interference in the presence of particle loss and derive an inequality that relates the preservation of coherence, the creation of superposition with the vacuum, and the degree of particle loss.
