Summary: This work suggests a simple and general route to targeted tuning in preparing porous carbons by understanding the Gibbs free energy evolution mechanism for solid activators at high temperatures. Based on a spatial confinement strategy, it is possible to produce pine sawdust-derived porous carbons with higher specific surface area. The texture properties can be tuned by various spatial confinement forces, bypassing the activation process tuning, template, sequential activation, and trial and-error methods.

Summary: A facile strategy is reported for preparing porous carbon materials with adjustable pore size through carbonization of MOF-5 at 900 degrees C with different additives. The physical and chemical properties of these materials can be adjusted by introducing different compounds during the carbonization process. CO2 adsorption experiments reveal that there is a linear relationship between CO2 adsorption capacity and cumulative pore volume in the range of 5-7 angstrom. The 5C-C6H14O6-900 material shows the highest CO2 adsorption capacity, with good stability and selectivity. This work provides a facile method to adjust and control pore size distribution of MOF-derived porous carbon materials, and highlights the importance of micropores in the adsorption of CO2 at low pressure.

Summary: This study investigates the effects of grass feedstock and grass-derived hydrochar produced at two different temperatures on the pore size distribution and saturated hydraulic conductivity of compacted silty-clay sand. The results show that the addition of an appropriate amount of 180 degrees C hydrochar can improve soil structure and increase saturated hydraulic conductivity. However, excessive addition of hydrochar may reduce the effectiveness of drainage improvement.

Summary: This study investigates the distribution characteristics of the horizontal stiffness of rubber bearings and its influence on the seismic performance of isolation structures. An optimization method to reduce the variation of bearing stiffness is proposed, and statistical analysis and probability distribution tests are conducted based on the equivalent shear stiffness samples of 224 rubber bearings. The results show that the stiffness follows the I-type minimum-value distribution. The study concludes that the probability distribution form of the rubber bearings stiffness has a certain influence on the adjustment coefficient of the isolation structure, but the damping effect of the structure still has sufficient safety reserve.

Summary: The quasi-static tests on precast sandwich wall structures with friction devices showed that the structures remained elastic and well-protected. Finite element analysis demonstrated that increasing the frictional force could enhance energy dissipation and lateral load resistance, but also led to larger residual displacements. Additionally, self-centering capability could be improved by increasing posttensioning force.

Summary: The central retina thickness, the combination of ganglion cell layer and inner plexiform layer thickness, and nerve fiber layer thickness were significantly decreased in patients with Parkinson's disease (PD). However, there was no significant difference in the thickness of the inner nuclear layer, outer plexiform layer, and outer nuclear layer between the eyes of PD patients and controls. Subgroup analysis and meta-regression results were consistent with the main findings.

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 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: 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.
