Summary: Metal-organic frameworks (MOFs)-derived nanoporous carbons are promising adsorbents for removing endocrine-disrupting chemicals (EDCs) from water. In this study, two nanoporous carbons derived from different Zn-MOFs were prepared and evaluated for their adsorption performance. The MOF-5-derived nanoporous carbon showed higher adsorption capacity and faster adsorption rate, and the adsorption mechanism was mainly attributed to hydrophobic interaction.

Summary: In this study, three-dimensional activated graphitic carbon spheres (AGCS) were synthesized by activating and graphitizing Fe-tannic acid coordination spheres with the help of KOH. The AGCS with nanosheets-assembled complex intersecting channel system can expose more active sites, which is beneficial for charge storage. Simultaneous activation-graphitization can also solve the trade-off relationship between porosity and conductivity of carbon materials. The optimized AGCS-2, with a large specific surface area, abundant ion-accessible micropores, good electronic conductivity, and moderate oxygen doping, shows excellent performance in zinc-ion hybrid capacitor (ZIHC) with high specific capacity, remarkable energy density, and superior cycling life.

Summary: In this study, copper-loaded activated carbon (Cu/AC) was successfully prepared as an effective adsorbent for CF4. The Cu/AC showed faster adsorption rate and larger adsorption capacity compared to commercial activated carbon and MOFs. Various characterization techniques were used to study the physical and chemical properties of Cu/AC before and after adsorption, revealing excellent recycling performance after 5 adsorption and desorption cycles. The adsorption process on Cu/AC surface was found to be exothermic and conform to pseudo-first-order, pseudo-second-order, and Freundlish adsorption models.

Summary: We propose utilizing laser-assisted carbonization of surface-grown UiO-66 to diversify the upcycling of waste PET into materials with enhanced photothermal properties. A solvo-thermal procedure was used to form a homogeneous UiO-66 layer on recycled PET sheets. Treatment with a 405 nm laser system enabled the formation of a carbonaceous layer with improved electrical conductivity and photothermal properties due to the presence of zirconium carbide and graphene. This approach presents new possibilities for the application of upcycled PET-based materials.

Summary: In this study, two novel phenazine-based CMPs, TPT-QP CMPs and Py-QP CMPs, were successfully synthesized through the Suzuki coupling condensation reaction. These CMPs have high surface areas and good thermal stabilities. TPT-QP CMPs, in particular, have abundant hydrogen-bonding sites and demonstrate high sensitivity and selectivity in detecting sub-ppm levels of volatile acidic hydrocarbons. Additionally, a quartz crystal microbalance (QCM) sensor based on TPT-QP CMPs was fabricated for the first time, showing excellent performance in detecting trace amounts of formaldehyde.

Summary: Hierarchically porous bimetallic zeolitic imidazolate framework (ZIF) particles (etched Zn33Co67-ZIF) were designed and prepared through an ethylene glycol-assisted aqueous etching method, which effectively increased their pore size and surface area. After thermal treatment, the etched Zn33Co67-ZIF particles transformed into cobalt and nitrogen co-doped hierarchically porous carbon (etched Zn33Co67-C), which exhibited increased mesoporosity and specific capacitance compared to the unetched one. The presented ethylene glycol-assisted aqueous etching process provides a facile template-free strategy for improving the energy storage performance of MOFs and their corresponding porous carbons.

Summary: The study investigates the therapeutic and optical properties of bismuth oxide particles (Bi2O3) for selective melanoma therapy and prevention. Bi2O3 particles induce apoptosis in A375 melanoma cells but not in HaCaT keratinocytes or CCD-1090SK fibroblast cells. The selective apoptosis is attributed to increased particle internalization and enhanced production of reactive oxygen species in A375 cells compared to HaCaT and CCD-1090SK cells.

Summary: High-quality emission centers in two-dimensional materials, such as carbon-enriched hexagonal boron nitride (hBN:C) layers, are promising for future photonic and optoelectronic applications. By placing hBN:C layers on Ag triangle nanoparticles (NPs), the decay time of atom-like color-center (CC) defects is accelerated to 46 ps from their bulk value of 350 ps, due to efficient excitation of plasmon modes. Simulations suggest higher Purcell values, and analysis reveals the influence of NP thickness on the Purcell factor of CCs. The ultrafast operation of CCs in hBN:C layers enables their use in demanding applications like single-photon emitters and quantum devices.

Summary: This study develops a novel approach to introduce halogen bonding elements into UiO-66 to fine-tune the adsorption properties towards chlorobenzenes. The highest adsorption capacity was achieved in UiO-66 loaded with 50% I-TA (UiO-66-Iopt) due to the balance between the number of halogen bonding elements and the surface area of UiO-66 structure. The formation of halogen bonding was experimentally verified and PET@UiO-66-Iopt showed excellent selectivity for the separation of chlorobenzenes.
