TL;DR: The effective synthesis method and excellent charge transport properties of AA'n-1MnX3n+1 type 2D perovskite single crystals make them promising candidates for the next generation of optoelectronic devices.
Abstract: Two-dimensional (2D) AA'n-1 Mn X3n+1 type halide perovskites incorporating straight-chain symmetric diammonium cations define a new type of structure, but their optoelectronic properties are largely unexplored. Reported here is the synthesis of a centimeter-sized AA'n-1 Mn X3n+1 type perovskite, BDAPbI4 (BDA=NH3 C4 H8 NH3 ), single crystal and its charge-transport properties under X-ray excitation. The crystal shows a staggered configuration of the [PbI6 ]4- layers, a band gap of 2.37 eV, and a low trap density of 3.1×109 cm-3 . The single-crystal X-ray detector exhibits an excellent sensitivity of 242 μC Gyair-1 cm-2 under the 10 V bias (0.31 V μm-1 ), a detection limit as low as 430 nGyair s-1 , ultrastable response current, a stable baseline with the lowest dark current drift of 6.06×10-9 nA cm-1 s-1 V-1 , and rapid response time of τrise =7.3 ms and τfall =22.5 ms. These crystals are promising candidates for the next generation of optoelectronic devices.

TL;DR: This treatment system decreased the discharge of iARGs to receiving environments, however, increased eARG concentrations were present in the effluent, which may contribute to the environmental resistome.

TL;DR: In this article, a surface-functionalized magnetic nanoparticle supported dual Bronsted acidic ionic liquid was synthesized by immobilizing 1-(propyl-3-sulfonate) imidazolium hydrogen sulfate [SO3H-(CH2)3-HIM][HSO4] onto the surface of Fe3O4@SiO2 using 3-chloropropyltrimethoxysilane as the linker.
Abstract: Surface-functionalized magnetic nanoparticle supported dual Bronsted acidic ionic liquid was synthesized by immobilizing 1-(propyl-3-sulfonate) imidazolium hydrogen sulfate [SO3H-(CH2)3-HIM][HSO4] onto the surface of Fe3O4@SiO2 using 3-chloropropyltrimethoxysilane as the “linker”. The structure of the catalyst was characterized by XRD, FT-IR, SEM, TEM, and VSM. The results demonstrated that the Fe3O4 particle was well retained in the silica matrix, presenting a core–shell structure with strong magnetic responsiveness. Meanwhile, the ionic liquid was successfully immobilized on the support. The as-prepared catalyst could disperse well in the reactants and showed good performance in esterification of oleic acid with short-chain alcohols and transesterification of soybean oil. Moreover, the catalyst could be easily separated from products by additional magnetic force without obvious mass loss and maintain satisfactory catalytic activity after being recycled eight times.

TL;DR: In this article, Ni decorated graphene nanoplate (Ni/Gn) catalysts with highly dispersed metal nano-particles (NPs) were introduced by using the hydriding combustion synthesis and mechanical milling (HCS + MM) method to obtain Mg-based composites.
Abstract: Magnesium hydride is considered as an ideal candidate for effective hydrogen storage due to its high gravimetric hydrogen capacity and accessibility. But its use as a commercial material is hindered by its relatively high operating temperatures and slow release/uptake kinetics. To solve this, we first synthesized Ni decorated graphene nanoplate (Ni/Gn) catalysts with highly dispersed metal nano-particles (NPs) via a facile method, then the as-prepared Ni/Gn catalysts were introduced by using the hydriding combustion synthesis and mechanical milling (HCS + MM) method to obtain Mg-based composites. Remarkable enhancement of hydrogen sorption rates has been found for these composites in the presence of Ni/Gn additives, especially for the Mg@Ni8Gn2 sample: a hydrogen absorption amount of 6.28 wt% within 100 s at 373 K and a hydrogen desorption amount of 5.73 wt% within 1800 s at 523 K. A rather low activation energy (71.8 kJ mol−1) for the dehydrogenation of MgH2 was determined in the same sample, indicating that relatively moderate temperatures are required to absorb/desorb hydrogen. The excellent hydrogen sorption rates of the composites are thought to be associated with the high dispersity of in situ formed nanometric Mg2NiH4 particles during the HCS + MM process. In addition, a microstrain-induced synergetic hydrogen sorption mechanism is proposed, being correlated by the local introduction of a Mg2Ni nano-catalyst into the Mg matrix.
