Rational Regulation of Reducibility and Acid Site on Mn-Fe-BTC to Achieve High Low-Temperature Catalytic Denitration Performance.

Selective catalytic reduction with ammonia is the mainstream technology of flue gas denitration (de-NO). The reducibility and acid site are two important factors affecting the de-NO performance, and effective regulation between them is the key to obtain a highly efficient de-NO catalyst. Herein, a series of Mn-Fe-BTC with different ratios of Mn and Fe are synthesized, among which 2Mn-1Fe-BTC with 2:1 molar ratio of Mn and Fe has excellent low-temperature (LT) de-NO performance (above 90% NO conversion between 60 and 270 °C) and good tolerance to HO and SO poisoning (88% NO conversion at 150 °C with 100 ppm of SO and/or 6% HO).

PdS Quantum Dots as a Hole Attractor Encapsulated into the MOF@CdZnS Heterostructure for Boosting Photocatalytic Hydrogen Evolution under Visible Light.

Herein, a new photocatalyst PdS@UiOS@CZS is successfully synthesized, where thiol-functionalized UiO-66 (UiOS), a metal-organic framework (MOF) material, is used as a host to encapsulate PdS quantum dots (QDs) in its cages, and CdZnS (CZS) solid solution nanoparticles (NPs) are anchored on its outer surface. The resultant PdS@UiOS@CZS with an optimal ratio between components displays an excellent photocatalytic H evolution rate of 46.1 mmol h g under visible light irradiation (420∼780 nm), which is 512.

Flexible and robust silicon/carbon nanotube anodes exhibiting high areal capacities.

The fast development of flexible devices has greatly boosted the demands for flexible lithium-ion batteries (LIBs). Accordingly, a broad exploration of flexible electrodes in LIBs is crucial. At present, the major challenge in the flexible electrode for lithium-ion batteries (LIBs) is how to achieve an excellent electrochemical performance (particularly high-energy density) while maintaining superior mechanical flexibility.

The synergy between electronic anchoring effect and internal electric field in CdS quantum dots decorated dandelion-like Fe-CeO nanoflowers for improved photocatalytic hydrogen evolution.

A series of dandelion-like Fe-CeO/CdS (FeCe/Cd) nanoflowers with different molar ratios of Fe-CeO to CdS are synthesized by solvothermal method for the first time. The FeCe/Cd nanoflowers are assembled by a large number of nanoparticles with the diameter of about 3 nm, and the introduction of Fe ions and the couple of CdS quantum dots (QDs) efficiently enhanced the relative percentage of Ce in CeO. The as-obtained FeCe/Cd heterostructure exhibits the highest photocatalytic H evolution ability of 108.

Cysteine transporter SLC3A1 promotes breast cancer tumorigenesis.

Cysteine is an essential amino acid for infants, aged people as well as patients with metabolic disorders. Although the thiol group of cysteine side chain is active in oxidative reactions, the role of cysteine in cancer remains largely unknown. Here, we report that the expression level of the solute carrier family 3, member 1 (SLC3A1), the cysteine carrier, tightly correlated with clinical stages and patients' survival.

Sustained attention is associated with error processing impairment: evidence from mental fatigue study in four-choice reaction time task.

Attention is important in error processing. Few studies have examined the link between sustained attention and error processing. In this study, we examined how error-related negativity (ERN) of a four-choice reaction time task was reduced in the mental fatigue condition and investigated the role of sustained attention in error processing.
