Photochemical Deracemization of N‐Carboxyanhydrides En Route to Chiral α‐Amino Acid Derivatives

Angewandte Chemie, Volume 137, Issue 6, February 3, 2025.
N‐Carboxyanhydrides 1 (NCAs) are activated α‐amino acid derivatives that can be modified in a minimum‐waste process to give a variety of products. Photochemical deracemization using chiral catalyst 2 for stereochemical editing of the α‐stereogenic center provided access to intermediates (R)‐1 that can be immediately subjected to further transformations.

Enhancing the Potency of Growth Factor‐Mimicking Peptides via Cross‐Presentation With Integrin Ligands

Journal of Biomedical Materials Research Part A, Volume 113, Issue 7, July 2025.
ABSTRACT Growth factors enhance survival and integration of transplanted Mesenchymal Stromal Cells (MSC), but successful supplementation often requires supraphysiological growth factor doses, risking off‐target effects. Short peptide mimics like the knuckle epitope (KE) of Bone Morphogenetic Protein 2 (BMP‐2) can be covalently immobilized to ...

On Quantum Statistical Inference, I

, 2003
Recent developments in the mathematical foundations of quantum mechanics have brought the theory closer to that of classical probability and statistics. On the other hand, the unique character of quantum physics sets many of the questions addressed apart

Design, Synthesis and Characterization of BODIPY based 1H‐Tetrazole Ligands

European Journal of Organic Chemistry, Volume 28, Issue 7, February 17, 2025.
A novel fluorescence active ligand system consisting of a BODIPY derivative, linked to a 1H‐tetrazol‐1‐yl coordinating moiety via alkyl or benzyl spacers, is presented. The designed ligands exhibit remarkable emission properties even in solid state, which is complemented by crystal structure analysis.

Topological Wilson-loop area law manifested using a superposition of loops

, 2013
We introduce a new topological effect involving interference of two meson loops, manifesting a path-independent topological area dependence. The effect also draws a connection between quark confinement, Wilson-loops and topological interference effects ...

Experimental estimation of the dimension of classical and quantum systems

, 2011
An overwhelming majority of experiments in classical and quantum physics make a priori assumptions about the dimension of the system under consideration.

Properties of thermal quantum states: locality of temperature, decay of correlations, and more

, 2019
We review several properties of thermal states of spin Hamiltonians with short range interactions. In particular, we focus on those aspects in which the application of tools coming from quantum information theory has been specially successful in the ...

Cs2AgBiBr6 Double Perovskite Single Crystal/ CsPbBr3 Perovskite Nanocrystals Heterojunction for High‐Performance X‐Ray Detection

Advanced Optical Materials, Volume 13, Issue 5, February 13, 2025.
Cs2AgBiBr6 single crystal/ CsPbBr3 nanocrystal film heterojunction demonstrates superior performance in direct X‐ray detection, operating with zero bias. This performance is driven by the efficient carrier separation and transport within the heterojunction.

Loading of Extracellular Vesicles with Nucleic Acids via Hybridization with Non‐Lamellar Liquid Crystalline Lipid Nanoparticles

Advanced Science, Volume 12, Issue 8, February 24, 2025.
This study explores how lipid nanoparticles interact with extracellular vesicles, emphasizing the importance of lipid nanoparticle topology in facilitating a controlled hybridization process between the two nanocarriers. The resulting hybrid nanoparticles display extracellular vesicle membrane proteins on their surface, are loaded with the nucleic acid

Long-range coupling and scalable architecture for superconducting flux qubits

, 2007
Constructing a fault-tolerant quantum computer is a daunting task. Given any design, it is possible to determine the maximum error rate of each type of component that can be tolerated while still permitting arbitrarily large-scale quantum computation. It
