Summary: The reaction mechanism of desert sand-high calcium fly ash-based alkali-activated mortar was investigated under different influencing factors in this study. Various properties of the developed mortar, including flowability, compressive and flexural resistance, micromorphological attributes, and reaction mechanism, were studied for alkali admixture, sodium silicate modulus, and ground granulated blast-furnace slag (GGBS) content. The results showed that an optimal range of Na2O/b (5%-8%) and sodium silicate modulus (1.0-1.5) led to good flowability and high compressive strength. The increase in GGBS content resulted in decreased flowability but increased compressive strength.

Summary: The growth of Pleurotus ostreatus, a saprotrophic fungus, has been found to induce water repellency in sands. This study investigates the effects of P. ostreatus growth on the hydraulic behavior of sand amended with organic matter over a 12-week period. The results show that fungal treatment leads to changes in wetting and drying curves, hydraulic conductivity, and infiltration rates, attributed to the clogging of soil pores by fungal hyphal biomass.

Summary: This study found that increasing the H2O/Na2O ratio in metakaolin-based geopolymers resulted in decreased compressive strength. However, it did not affect the geopolymer structure but impacted the reactivity of the precursor and porosity evolution. The reaction degree, as deduced from NMR spectral analysis, correlated with the cumulated released heat determined by isothermal calorimetry. The maximum loss tangent from dynamic rheology was linearly related to strength development.

Summary: This study proposes a simple and versatile method for preparing Zn(II)-poly(carboxylates) reticulated binders, which significantly improve the electrochemical performance of silicon-based negative electrodes. The formation of carboxylate-Zn(II) coordination bonds is investigated, and mechanical characterizations reveal better cohesion, adhesion, hardness, and elastic modulus of the coordinated binder. Operando dilatometry experiments show reduced electrode expansion and improved capacity retention of over 30% after 60 cycles for the coordinatively reticulated electrodes.

Summary: The functionalization of MXenes, a class of 2D materials, can significantly modify their physicochemical properties. Through experiments and theoretical calculations, we found that the carbon NMR signal in MXenes is highly sensitive to functionalization, even though carbon atoms are not directly bonded to the surface groups. We developed a theoretical model to quantitatively relate the 13C NMR shift to different surface compositions and the number of surface chemistry variants induced by different etching agents.

Summary: Flood embankments are usually designed assuming steady-state flow conditions and dry soil above the phreatic surface. However, considering transient water flow and partial saturation can lead to significant savings in terms of earthfill material and footprint. This study examines the case of flood embankments in the tidal area of the Elbe River in Germany and compares the conventional prescriptive design with a performance-based design that allows for steeper slopes on the landside. The results show that raising the embankment with a 1:1 landside slope instead of 1:3 can result in cost and carbon savings.

Summary: This study proposes a simple and versatile method for preparing Zn(II)-poly(carboxylates) reticulated binders by adding Zn(II) precursors into a preoptimized poly(carboxylic acids) binder solution. These binders significantly improve the electrochemical performance of silicon-based negative electrodes. The formation of carboxylate-Zn(II) coordination bonds is investigated using rheology and spectroscopic techniques. Mechanical characterizations show that the coordinated binder offers better electrode coating cohesion and adhesion, as well as higher hardness and elastic modulus, even in the presence of a carbonate solvent. Operando dilatometry experiments demonstrate that the electrode expansion during lithiation is reduced, mitigating electrode mechanical failure. These coordinatively reticulated electrodes outperform their uncoordinated counterparts with an improved capacity retention of over 30% after 60 cycles.

Summary: Recently, metal-organic frameworks (MOFs) that combine organic and inorganic redox-active moieties have attracted attention in electrochemical energy storage. In this study, we focused on MIL-53(M) (M = Al, Fe) analogues based on 2,5-dioxo-1,4-benzenedicarboxylate, as this ligand has shown interesting electrochemical activity in the solid state. We attempted to chemically lithiate the title solids through various synthetic paths and characterized the resulting solids using several techniques. We found that the lithiation process differed significantly for M = Al and Fe, and evaluated the electrochemical extraction/uptake of Li+ in the lithiated derivatives. Although their storage capacities were moderate, the presence of a minor amount of M3+ cations improved the long term capacity retention.

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.
