Boron-Catalyzed α‑Amination of Carboxylic Acids

, 2019
A boron-catalyzed α-amination of simple carboxylic acids was developed. Catalytically generated boron enolates of carboxylic acids reacted with an electrophilic aminating reagent, diisopropylazodicarboxylate, to provide amino acid derivatives.

Wybór obiektywnej niepewności jako postawa filozofii egzystencji. Soren Kierkegaard i Odo Marquard (Choosing Objective Uncertainty as an Attitude of Existential Philosophy. Soren Kierkegaard and Odo Marquard) [PDF]

Analiza i Egzystencja, 2011
The idea of the article is to search for the roots of the so-called existential thinking, using the peculiar comparison: of the religiously oriented ideas of Kierkegaard ( especially his notions of subjective and objective thinker and the idea of ...

Unveiling Exsolution‐Induced Giant Electronic and Magnetic Property Changes in Non‐Stoichiometric Titanate Perovskite Thin Films

Advanced Materials, EarlyView.
A giant insulator to metal transition and emergent superparamagnetism are revealed by nanoparticle exsolution in non‐stoichiometric titanate perovskite thin films. By combining transport, synchrotron spectroscopy, and first‐principles calculations, this work reveals how defect reconfiguration and lattice reconstruction fundamentally reshape electronic ...

CVD Grown Hybrid MoSe2–WSe2 Lateral/Vertical Heterostructures With Strong Interlayer Exciton Emission

Advanced Materials, EarlyView.
A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

Boron Buckminsterfullerene

Chemical Science
Fullerenes, spherical molecules made entirely of carbon atoms, have played a foundational role in the birth of nanoscience. Despite extensive research, however, comparable structures composed of other elements has remained elusive, highlighting the unique bonding properties of carbon that enable the formation of such remarkable ...

Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries

Advanced Materials, EarlyView.
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...
