Summary: The research aimed to reduce the adsorption of protein-bound and uremic toxins using mordenite zeolite as an adsorbent and different pore generating agents. The experiments showed that the concentration of mordenite zeolite affects membrane performance, with larger pore size leading to decreased solute rejection but increased creatinine uptake level.

Summary: The study investigated the adsorption behavior of phenylpyrazole insecticide-fipronil, an endocrine disrupting compound, on modified zeolites. The results showed that the Langmuir adsorption isotherm and pseudo-second-order kinetic model well described the adsorption process. Thermodynamics revealed that the adsorption process is spontaneous and exothermic.

Summary: Strong gas-mineral interactions and slow adsorption kinetics affect gas mobility in zeolite pores, especially at pore-limiting window sites. This study combines molecular simulations and experiments to investigate noble gas adsorption and mobility in two zeolites. The results show that even the largest gas (Rn) can be accommodated in both zeolites, but gas mobility is significantly hindered in clinoptilolite. The experimental results confirm the presence of a kinetic barrier to Xe uptake, resulting in reverse Kr/Xe selectivity. A kinetic model is used to compare gas diffusivity in the zeolite pores.

Summary: The Lewis acidic aluminum in zeolites can be transformed into octahedrally coordinated aluminum, which serves as the precursor of Lewis acid sites. These Lewis acid sites preferentially locate in the pore structure of mordenite, particularly in the side-pockets. By reverting the octahedrally coordinated aluminum back to a tetrahedral geometry, the corresponding Bronsted acid sites are restored, showing a reversible switch between Lewis and Bronsted acidity.

Summary: This study aimed to evaluate the epidemiology of the urea-to-creatinine ratio (UCR) in hospitalized chronic kidney disease patients and its association with clinical outcomes. The results showed that elevated UCR was associated with increased inpatient mortality, hospital readmission, and longer hospital length-of-stay. Further investigation is warranted to understand the pathophysiological basis of this relationship and identify effective interventions.

Summary: This study investigated the application of mordenite in the adsorptive removal of Fe(III) from aqueous solution. Mordenite zeolite was synthesized hydrothermally without using an organic template, and characterized using X-ray diffraction (XRD) and Thermogravimetric analysis (TGA). The study examined the effect of various experimental parameters such as pH, contact time, and initial metal concentration on the adsorption process. The results showed that the Langmuir model accurately explained the adsorption data, indicating that Fe(III) adsorption from aqueous solution occurs through monolayer adsorption. The adsorption kinetic model was well-fitted by the pseudo-second-order kinetic model.

Summary: Adsorbing toxins from blood to enhance hemodialysis is a trending research area. Films composed of p(PM fiCD-co-MPC)-coated magnetic nanoparticles were investigated for their effects on protein denaturation and plasma stability. The modified surfaces exhibited reduced protein adsorption and the ratio of CD to MPC had a negative impact on platelets.

Summary: Developing new and efficient methods as an alternative to hemodialysis is crucial due to challenges associated with low membrane efficiency and long dialysis sessions. Metal organic frameworks (MOFs) have recently gained interest in the membrane community for their tunable properties, and this study computationally evaluated membrane-based uremic toxin separation performances of 60 bio-compatible MOFs. Results showed that certain MOFs exhibited high membrane selectivities for urea/water and creatinine/water separations, and considering the structural flexibility of MOFs significantly enhanced membrane selectivities for urea/water separations.

Summary: Highly efficient CO2 utilization methodologies combining methanol synthesis catalysts and methanol conversion catalysts have been developed. The use of ZnO/ZrO2 as the catalyst for methanol synthesis and MOR zeolites as the catalyst for methanol conversion enables one-pass hydrocarbon production via CO2 hydrogenation. By physically mixing these catalysts, bifunctional catalysts are formed, which operate at low pressure and have shown promising results in terms of olefin selectivity.

Summary: Porous hybrid electrolytes based on PEG and mesoporous silica were prepared by modifying the silica matrix and embedding a complex of lithium salt and PEG in the silica pores. The hybrid materials showed slightly mesoporous characteristics and exhibited high ionic conductivity when filled with the PEG-LiTFSI complex. The study also demonstrated the importance of filling both inter- and intraparticle porosity for improved conductivity.

Summary: MOF materials with adjustable pore structure and polymetallic sites have been explored as electrocatalysts for OER. Bimetallic materials show higher electrocatalytic activity than monometallic materials, while carbon-coated and doped MOF catalysts exhibit stable and good OER activity. The synergistic interaction between polymetallic active sites effectively improves the intrinsic activity of MOF on OER.

Summary: This study focuses on using a functional separator to suppress the shuttle effect of soluble lithium polysulfides in Li-S batteries. It is found that the functionalized sulfonic acid group not only accelerates the conduction of lithium ions, but also repels polysulfide anions through electrostatic interactions. The performance of the batteries is significantly improved with the use of this functionalized separator.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.

Summary: This study presents a new method for preparing a microporous Ni2P/C catalyst with high catalytic activity. The redox reaction and carbon matrix formation during high-temperature treatment contribute to the stability and activity of the catalyst. Experimental and analytical results suggest that the microporous structure of the composite plays a crucial role in its catalytic performance. These findings are important for practical applications of efficient hydrogen production by water electrolysis.

Summary: First principles calculations were used to investigate the pathway for methylation of benzene with methane catalyzed by MFI type zeolite-supported Co species. The strong adsorption of benzene on Co is found to lower the activation energy for methane dissociation and promote the formation of toluene precursor. The activation energy of methane dissociation is also affected by the Al-Al distance.
