N-doped carbon nanofibers embedded with Fe/Fe3C nanodomains demonstrate superior electrocatalytic nitrate reduction ability and nitrogen selectivity.

Effective deposition of MOFs on "inert" solid surfaces is very challenging. In this work, we found that polydopamine, which can be facilely and tightly formed on any types as well as any forms of solid surfaces, could be used as an effective nucleation center for MOF deposition. Based on this finding, various MOFs were successfully deposited onto nanofibrous polymer membranes, especially the commercially available "inert" ones, affording hierarchically structured porous films.

A novel strategy for highly sensitive detection and discrimination of explosives is developed based on the metal–organic polyhedra (MOP)‐decorated plasmonic substrate. It is found that the careful selection of the geometric and electronic characteristics of the assembly units (organic ligands and unsaturated metals sites) embedded within the MOP cage allows for the integration of multiple weak molecular interactions in a controllable fashion and thus the MOP cage can serve as an excellent receptor for selective uptake and binding of explosives. By further grafting of the MOP cage onto a plasmonic substrate with good surface‐enhanced Raman scattering enhancement factor, the resulting sensor shows a good sensing capability to various groups of ultratrace explosives, especially the challenging aliphatic nitro‐organics.

A series of tetraphenylethylene (TPE)-bile acid conjugates was described. It was found that the synergetic combination of the distinct properties of TPE and bile acid units could directly afford uniform fluorescent vesicles with amphiphilic binding pockets in the membrane. This structural features of such vesicles provides a unique opportunity for facile construction of functional chemical systems through host-guest chemistry.

Transcranial near-infrared (NIR) treatment of neurological diseases has gained recent momentum. However, the low NIR dose available to the brain, which shows severe scattering and absorption of the photons by human tissues, largely limits its effectiveness in clinical use. Hereby, we propose to take advantage of the strong scattering effect of the cranial tissues by applying an evenly distributed multiunit emitter array on the scalp to enhance the cerebral photon density while maintaining each single emitter operating under the safe thermal limit. By employing the Monte Carlo method, we simulated the transcranial propagation of the array emitted light and demonstrated markedly enhanced intracranial photon flux as well as improved uniformity of the photon distribution. These enhancements are correlated with the source location, density, and wavelength of light. To the best of our knowledge, we present the first systematic analysis of the intracranial light field established by the scalp-applied multisource array and reveal a strategy for the optimization of the therapeutic effects of the NIR radiation.

In this paper, an infrared annealing method was proposed for solution-processed indium gallium zinc oxide films. The optimized IGZO thin-film transistors (TFTs) exhibited a field-effect mobility of 2.04 cm 2 (Vs) -1 , on-off current ratio of 1.52 × 10 6 and subthreshold swing of 0.84 V/dec. Spectroscopic analysis confirmed that the infrared irradiation could enhance the removal of organic species and dehydroxylation. The results suggest that infrared annealing method is a potential process for low-temperature preparation of solution-processed oxide semiconductor layers and dielectric layers, and can be applied to the fabrication of TFT devices.
