α-Quaternary Chiral Aldehydes from Styrenes, Allylic Alcohols, and Syngas via Multi-catalyst Relay Catalysis 10.1016/j.chempr.2018.03.010 2018-04-05 Mimicking the way nature synthesizes organic molecules, multi-catalyst relay catalysis (MCRC), based on the seamless combination of a series of catalytic reactions, has emerged as a promising strategy for achieving ideal synthesis. In such systems, each step ...
Quasi-MOF: Exposing Inorganic Nodes to Guest Metal Nanoparticles for Drastically Enhanced Catalytic Activity 10.1016/j.chempr.2018.03.009 2018-04-05 Metal-organic frameworks (MOFs) are excellent supports for metal nanoparticles (NPs), but the interactions between metal NPs and inorganic nodes of MOFs are weak because of the presence of organic ligands. Here, we present a strategy for strengthening the met...
A Fully Sodiated NaVOPO4 with Layered Structure for High-Voltage and Long-Lifespan Sodium-Ion Batteries 10.1016/j.chempr.2018.03.006 2018-04-05 Sodium-ion batteries are the primary candidate for a low-cost and resource-abundant alternative to lithium-ion batteries for large-scale electric storage applications. However, the development of sodium-ion batteries is hindered by the lack of suitable cathod...
Hierarchically Engineered Mesoporous Metal-Organic Frameworks toward Cell-free Immobilized Enzyme Systems 10.1016/j.chempr.2018.03.001 2018-03-29 Highly efficient cell-free enzymatic systems are typically difficult to achieve in traditional immobilized enzyme systems because of the lack of optimal spatial control of enzyme localization, substrate and product diffusion, and enzyme and coenzyme accessibi...
Plasmon-Mediated Electron Injection from Au Nanorods into MoS2: Traditional versus Photoexcitation Mechanism 10.1016/j.chempr.2018.02.025 2018-03-29 Using nonadiabatic molecular dynamics simulations combined with time-domain density functional theory, we show that electron injection from gold nanorods into MoS2by the traditional mechanism is still faster than energy relaxation causing charge recombination...
In Situ Generation of Bifunctional, Efficient Fe-Based Catalysts from Mackinawite Iron Sulfide for Water Splitting 10.1016/j.chempr.2018.02.023 2018-03-29 Water splitting requires nonprecious materials that can catalyze efficiently both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER). Here, we report the synthesis of mackinawite FeS nanosheets grown on iron foam, which can serve as...
Seeing Elastin: A Near-Infrared Zwitterionic Fluorescent Probe for In Vivo Elastin Imaging 10.1016/j.chempr.2018.02.016 2018-03-29 Elastic fibers are present in a variety of tissues and are responsible for their resilience. Until now, no optical contrast agent in the near-infrared (NIR) wavelength range of 700–900 nm has been reported for the imaging of elastic fibers. Here, we report th...
G-Quadruplex: A Regulator of Gene Expression and Its Chemical Targeting 10.1016/j.chempr.2018.02.014 2018-03-22 G-quadruplex (G4) is an important type of nucleic acid secondary structure. An abundance of potential G4-forming sites have been shown to exist in genomes, leading to increasing interest in this research field. G4 motifs are thought to be involved in the regu...
