Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth

open access: yesAdvanced Functional Materials, EarlyView.
Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

1H NMR Analysis of Deuterated Fatty Acid Methyl Esters

open access: yesJournal of Japan Oil Chemists' Society, 1981
Stearic-9, 10-d2, stearic-9, 9, 10, 10-d4, oleic-9, 10-d2, decanoic-3, 3-d2, lauric-3, 3-d2, myristic-3, 3-d2, palmitic-3, 3-d2, and stearic-3, 3-d2 acids were synthesized, and 1H NMR spectra of the methyl esters of these deuterated acids were measured. The signals due to the protons which were substituted by deuterons disappeared on the 1H NMR spectra

NMR Experiments for the Analysis of Mixtures: Beyond 1D 1H Spectra

open access: yesCombinatorial Chemistry & High Throughput Screening, 2012
State-of-the-art technologies and methodologies in NMR spectroscopy make it possible to obtain very informative and high-quality spectra in much less experimental time than classical methods by making better choices of NMR pulse sequences and acquisition parameters.

Enhanced Nitric Oxide Electroreduction to Ammonia via Modulating Spin‐Polarization of Fe Single‐Atom Catalysts

open access: yesAdvanced Functional Materials, EarlyView.
A strategic spin‐polarization suppression in Fe single‐atom catalysts is proposed to enhance electrocatalytic reduction of NO to NH3. Employing a top‐down electrospinning strategy, self‐supported FeSAC with Fe‐N3S1 coordination structure and spin‐state transition is engineered from high‐spin to low‐spin.

Chiral Nanohoops as an Efficient Spin Polarization System

open access: yesAdvanced Functional Materials, EarlyView.
Chiral conjugated nanohoops with a central dibenzopentalene unit exhibit 90% spin polarization at low voltage and high conductivity. These properties make them ideal components in molecular spintronics applications. Abstract A central challenge in molecular spintronics is to achieve a high spin polarization at low operating voltages and ambient ...
