Advances in Parahydrogen‐Induced Polarization for Nuclear Magnetic Resonance of Peptides, Proteins, and Biopolymers

ChemistryEurope, EarlyView.
Hyperpolarization by parahydrogen‐induced polarization enhances the sensitivity of nuclear magnetic resonance spectroscopy of amino acids, peptides, mini‐proteins, and biopolymers using nonnatural amino acids with unsaturated side chains up to three orders of magnitude.

Razão prática pura como uma faculdade natural

Ethic@: an International Journal for Moral Philosophy, 2006
Kant considered pure reason to be transcendentally free in its legislative ability.  I argue that this transcendental freedom is consistent with an naturalist ontologythat recognizes the existence only of objects in space and time.  I

Construction of Phospholipid‐Like Vesicles by Aqueous Aminolysis of Acyl Thioesters With Diamino Acids

Chemistry – A European Journal, EarlyView.
Membrane‐forming phospholipids are produced in cells via enzymatic diacylation. Here, we show that direct aminolysis of acyl thioesters with diamino acids in aqueous environments enables the synthesis of diacylated amino acids (DAAAs), which spontaneously self‐assemble into robust phospholipid‐like vesicles across a broad range of pH and temperature ...

Inelastically scattering particles and wealth distribution in an open economy

, 2003
Using the analogy with inelastic granular gasses we introduce a model for wealth exchange in society. The dynamics is governed by a kinetic equation, which allows for self-similar solutions.

Synthetic Studies towards Darobactin A

Chemistry – A European Journal, EarlyView.
The urgent need for new antibiotics led us to develop a new methodology for the synthesis of the natural product darobactin A selectively targeting gram‐negative bacteria. This study provides new insights into the synthesis of strained indole‐containing macrocycles.

Rational Design Strategies for Stimuli‐Responsive DNAzymes Using Modified and Artificial Nucleotides

Chemistry – A European Journal, EarlyView.
Activity control of RNA‐cleaving DNAzymes in response to external stimuli has attracted growing interest for applications in DNA‐based diagnostics, therapeutics, and dynamic DNA nanotechnology. This review summarizes rational design strategies for stimuli‐responsive DNAzymes using modified or artificial nucleotides, including split and caged DNAzymes ...

More on the universal equation for Efimov states

, 2019
Efimov states are a sequence of shallow three-body bound states that arise when the two-body scattering length is much larger than the range of the interaction. The binding energies of these states are described as a function of the scattering length and
