TL;DR: In this paper, the authors mainly focus on the design and applications of MOF-based antitumor agents, and four aspects covering the whole field are introduced: MOF as carriers, MOFs as anti-malignancy agents, MOF drug synergistic systems, and MOF derived antitumour agents.
Abstract: Metal-organic frameworks (MOFs) hold great promise for biomedical applications owing to their unique properties. The porous structures make MOFs excellent candidates for the delivery of different drugs; the flexibility in choosing metal ions and organic ligands makes it feasible to prepare MOFs with intrinsic antitumor activities and further devise MOF-drug synergistic systems; many other types of antitumor agents could also be developed using MOFs as the precursors/templates. Thus, the past two decades have witnessed the great development of MOF-based drugs, especially in the antitumor field. This Minireview mainly focuses on the design and applications of MOF-based antitumor agents. Four aspects covering the whole field are introduced: MOFs as carriers, MOFs as antitumor agents, MOF-drug synergistic systems, and MOF-derived antitumor agents. The challenges and opportunities of MOFs for clinical antitumor applications are also discussed.

TL;DR: Two metal nanoparticle-loaded and porphyrin-containing homochiral covalent organic framework-based composite catalysts are reported that exhibit high stereoselectivity and yield in the thermally-driven asymmetric reactions.
Abstract: For seeking high enantiopurity, the previously reported thermal asymmetric catalysis is usually carried out at low temperature sometimes with limited yield, that is, the high enantiomeric excess (ee) usually at the cost of high yield. Thus, the achieving both high stereoselectivity and yield is an enormous challenge. We report herein two metal nanoparticle (M NP)-loaded and porphyrin-containing homochiral covalent organic framework (CCOF)-based composite catalysts, and their application in the thermally-driven asymmetric one-pot Henry and A3-coupling reactions. All the reactions are conducted at elevated temperatures with both excellent stereoselectivity and yield which resulted from the synergy of CCOF confinement effect and M NP catalytic activation. Notably, the needed thermal energy for the asymmetric reactions herein is derived from the photothermal conversion via porphyrin-based CCOF upon irradiation with visible light. Remarkably, the CCOF confinement effect can be effectively maintained up to 100 °C for the asymmetric one-pot Henry and A3-coupling reactions herein. Achieving both high stereoselectivity and yield is a challenge for conventional asymmetric catalysis. Here, the authors report two metal nanoparticle-loaded and porphyrin-containing homochiral covalent organic framework-based composite catalysts that exhibit high stereoselectivity and yield in the thermally-driven asymmetric reactions.

TL;DR: In this article, a hierarchical TiO2 nanotube with uniform carbon coatings is synthesized as the full solar spectrum photocatalytic materials for O2 evolution by a facile solvothermal method.
Abstract: Smart architectures of TiO2 are attracting increasing attention due to their outstanding properties in a broad range of fields. Herein, hierarchical TiO2 nanotube with uniform carbon coatings is synthesized as the full solar spectrum photocatalytic materials for O2 evolution by a facile solvothermal method. This unique structure consists of an interstitial hollow spaces and a functional nanotube shell assembled from two-dimensional (2D) nanosheets. By adjusting the types of solvents and reaction time, the morphologies of TiO2/C composites can be tuned to nanoparticles, nanorods, or hierarchical nanotubes. Among these morphologies, the TiO2/C hierarchical nanotube exhibits the best photocatalytic activity and favorable stability toward oxygen evolution from water oxidation under full solar spectrum light irradiation. The reason is attributed to the desirable incorporation of visible/near-infrared (NIR) light active carbon coating with UV light responsive TiO2 for promoted solar energy utilization. Besides, the solvothermal step leads to hierarchical nanotube structures which can generate multiple reflections of incident light so as to promote an efficient light harvesting due to an enhanced specific surface area (244.4 m2 g−1) and light scattering ability. Moreover, the generated carbon coatings on the surface of TiO2 facilitate electron-hole separation.

Abstract: We report the first demonstration, to our knowledge, of passive Q-switched mode-locking in a Tm3+:YAP laser, operating in the 2 μm broadly spectral region formed with a compact Z-flod cavity. A transmission-type single-walled carbon nanotube saturable absorber (SWCNT–SA) is used for the initiation of the pulse generation. The repetition rate of the Q-switched envelope was 60 kHz at the pump power of 8.6 W. The mode-locked pulses inside the Q-switched pulse envelope had a repetition rate of ∼92 MHz. A maximum average output power of 761 mW was obtained. The dependence of the operational parameters on the pump power was also investigated experimentally.

TL;DR: The regression results suggest that PM2.5 in a city was positively related to its population size, amount of atmospheric pollutants, and emissions from nearby cities, but inversely related to precipitation and wind speed, which can shed new light on the complex spatiotemporal patterns of PM1.5 throughout China.
