Summary: This study investigated the role of silicon in the bioavailability of aluminum and found that silicon can decrease aluminum accumulation in the liver, kidneys, and bones. However, this effect is less pronounced in the presence of parenteral nutrition compounds. Additionally, silicon can accumulate in tissues, especially when administered together with phosphate.

Summary: This study investigates the ability of aqueous phosphate solutions to enhance the surface properties of cement pastes through the formation of low-solubility calcium phosphate (CaP) phases. Diammonium hydrogen phosphate (DAP), dipotassium hydrogen phosphate (DPP), and disodium hydrogen phosphate (DSP) were studied using thermodynamic modeling and experiments. The best results were obtained with a 1 M DPP + 1 mM CaCl2 solution applied to cement hydrated for 7 days, resulting in a CaP coating that significantly improved the resistance to abrasion, surface indentation, and staining of the cement pastes. Preliminary durability tests confirmed that no efflorescence occurred, indicating the environmental sustainability of the treatment.

Summary: Biocompatible ceramics are vital in bioengineering and have great potential in biomedical and orthopedic fields. Calcium phosphates, particularly hydroxyapatite, are the most suitable bioceramics due to their similarity to human bones. These can be used as bone substitutes, drug carriers, and coatings. However, bioceramics suffer from brittleness and poor mechanical properties. By doping calcium phosphates with active biomolecules and combining them with biopolymers, new possibilities for applications arise. This review explores the recent advancements in calcium phosphate-biopolymer composites, emphasizing their potential in healthcare, bone healing, and orthopedic surgeries.

Summary: The study investigated the effects of adding Pluronic F127 (PF127) to the electrolyte solution on the structure, morphology, and antibacterial growth of calcium phosphate (CaP) coatings synthesized by an electrochemical method on a titanium substrate. The structure and morphology were found to mainly depend on the PF127 wt% and deposition temperature at shorter deposition times. Interestingly, the addition of PF127 at higher deposition times using higher concentrations did not influence the structure and morphology.

Summary: To increase chemical reaction rates, general solutions include increasing the concentration/temperature and introducing catalysts. In this study, the rate constant of an electrophilic metal coordination reaction is accelerated 23-fold on the surface of layered aluminosilicate (LAS), where the reaction substrate (ligand molecule) induces dielectric polarization owing to the polar and anionic surface. This unique method to accelerate the chemical reaction is expected to expand the range of utilization of LASs, which are chemically inert, abundant, and environmentally friendly. The concept is also applicable to other metal oxides which have polar surfaces, which will be useful for various chemical reactions in the future.

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: In this study, a hybrid material of pyrazine-based pi-conjugated organic molecule, hexaazatrinaphthalene (HATN), and MXene was reported. The combination of MXene as a conductive substrate and HATN as an electroactive material resulted in a unique 3D structure with increased ion transport channels, leading to enhanced charge transfer and ion diffusion rates. The obtained HATN/MXene composite exhibited a high desalination capacity of 57.5 mg g(-1), a fast desalination rate of 13.2 mg g(-1) min(-1), and good long-term stability. This work provides valuable insights for the design and application of organic molecules in the field of capacitive deionization.

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.
