Harnessing Solar Energy for Ammonia Synthesis from Nitrogen and Seawater Using Oxynitride Semiconductors

open access: yesAdvanced Energy Materials, EarlyView.
In this work, the challenging green ammonia evolution is addressed by developing a photothermal system that utilizes nitrogen and natural seawater under simulated solar irradiation, employing ruthenium‐doped barium tantalum oxynitride semiconductors.

Robin boundary conditions are generic in quantum mechanics

open access: yes, 2016
Robin (or mixed) boundary conditions in quantum mechanics have received considerable attention in the last two decades, in particular, for applications to nanoscale systems. However, their utility has remained obscure to the larger physics community; in fact, one may find extant claims in the literature about the supposed naturalness of the specific ...

Scandium Induced Structural Disorder and Vacancy Engineering in Li3Sb – Superior Ionic Conductivity in Li3−3xScxSb

open access: yesAdvanced Energy Materials, EarlyView.
A superionic conductivity of 42 mS cm−1 at 298 K is reported for Li2.55Sc0.15Sb, which exceeds the highest ionic conductivity reported for a solid Li‐ion conductor to date by 10 mS cm−1. In the series Li3−3xScxSb (0 < x ≤ 0.15), the gradual incorporation of Sc facilitates vacancy formation, converting pristine Li3Sb from an electrical to an ionic ...

Dynamical Casimir effect with Robin boundary conditions

open access: yes, 2005
We consider a massless scalar field in 1+1 dimensions that satisfies a Robin boundary condition at a non-relativistic moving boundary. Using the perturbative approach introduced by Ford and Vilenkin, we compute the total force on the moving boundary.

Degradation of NiMo Catalyst Under Intermittent Operation of Anion Exchange Membrane Water Electrolyzer and its Mitigation by Carbon Encapsulation

open access: yesAdvanced Energy Materials, EarlyView.
Herein, by employing a reference electrode, the durability of anion exchange membrane water electrolyzer (AEMWE) under intermittent condition is demonstrated to be governed by the stability of the cathode catalyst. By encapsulating NiMo catalyst with carbon shells, the oxidation‐induced irreversible transformation to inactive hydroxide is prevented ...

Catch, Cut, or Block? Versatile 4‐N‐Derivatized Sialyl Glycosides for Influenza Virus Neuraminidase Detection and Purification

open access: yesAngewandte Chemie, EarlyView.
Sialyl glycosides containing 4‐N‐derivatized sialic acids synthesized by a highly efficient one‐pot two‐enzyme (OP2E) chemoenzymatic sialylation strategy have been shown to be versatile probes. They can resist sialidase cleavage, be selective substrates by influenza sialidases, or be nanomolar substrate analog‐based inhibitors and affinity ligands ...

The effect of geographical denomination on the uptake of fungus‐resistant grapes

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Grape production for wine making is of great economic and cultural importance in Europe, but is heavily dependent on pesticides. Reducing pesticide use and associated risks is a policy goal in several countries, particularly in Europe. The most effective strategy to substantially reduce pesticide use in grape production is the planting of ...

Self‐Photosensitizing Cobalt Complexes for Photocatalytic CO2 Reduction Coupled with CH3OH Oxidation

open access: yesAngewandte Chemie, EarlyView.
Self‐photosensitizing non‐noble metal complexes achieve CO2 photoreduction coupled with CH3OH photooxidation, simultaneously synthesizing formic acid in the absence of any additional photosensitizers and electron sacrificial reductants. Abstract The use of metal complexes as homogeneous molecular catalysts has attracted considerable attention regarding

Enhanced and Durable Light‐Driven Hydrogen Evolution by Cobalt‐Based Prussian Blue Analogs in Phospholipid Bilayers

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Light‐driven H2 evolution catalysis is reported for oleylamine‐capped MCo Prussian blue analogs (PBAs, M = Ni, Co, Zn, Cu) within phospholipid bilayers and using a ruthenium‐based amphiphilic photosensitizer. The hydrophobic interactions between the active units bring them in close proximity facilitating catalysis.

Taxonomy of Chemical Bondings: Opportunities and Challenges

open access: yesAngewandte Chemie, EarlyView.
The recent focus on supramolecular and nanosized systems produced a major increase in the types of observed noncovalent interactions and in the diversity of terms used to designate them. A hierarchical categorization (taxonomy) of terms used to designate electrophile···nucleophile interactions is proposed here.
