Summary: A new field-free and highly ordered spherical nucleic acid (SNA) nanostructure was self-assembled using ferrocene-labeled DNA tweezers and DNA linkers, serving as an ECL switch for improved recognition efficiency. Combined with mesoporous silica nanospheres (mSiO(2) NSs) filled with Rub-Pt nanoparticles (Rub-Pt@mSiO(2) NSs), a highly sensitive detection platform for let-7b microRNA was achieved through target-triggered SNA deconstruction, highlighting potential applications in biomarker analyses.

Summary: This study reported the use of reflection anisotropy spectroscopy (RAS) as an in situ characterization technique for non-aqueous battery systems, specifically AlBs. It demonstrated the changes in the solid-electrolyte interface structure during operation conditions and showed the applicability of RAS in monitoring phenomena such as plating/stripping and surface passivation in real-time.

Summary: The addition of 0.01 wt.% Ga in Al-0.4Mg-0.05Sn-0.03Hg anode enhances its corrosion resistance and discharge activity by refining second phases and creating a homogenous microstructure, which restrains local crystallographic corrosion and chunk effect. The corrosion current density and mass loss rate of Al-Mg-Sn-Hg-Ga anode decrease by 57% and 93% respectively compared to Al-Mg-Sn-Hg anode. The discharge voltage, current efficiency, and specific capacity of the Al-air battery with Al-0.4Mg-0.05Sn-0.03Hg-0.01Ga anode are 1.46 V, 33.1%, and 1019.2 A.h.kg(-1) when discharging at a current density of 20 mA/cm(2). Activation mechanism of Ga on Al-Mg-Sn-Hg-Ga anode materials was also discussed.

Summary: This study reports on the optimization of macrocyclic calix[4]quinone as excellent cathode materials for high-energy-density AABs, showing high capacity, rate capability, and low-temperature performance. Experimental and theoretical calculations prove that Al(OTF)(2+) cations coordinate with the carbonyl groups of C4Q during the discharge process, reducing desolvation penalty.

Summary: The electrochemical behavior of aluminum foil anodes is influenced by the lithiated areal capacity per cycle and alloy composition. Higher areal capacities result in faster degradation, while alloy composition affects Coulombic efficiency and long-term stability. In addition, different materials exhibit different reaction mechanisms, as observed by operando optical microscopy.

Summary: This study focuses on surface treatment processes of 6061 aluminum alloy profile coatings in the construction industry, including sand powder film coating, flat powder coating, hard anodized film, and ordinary heat-sealing oxidized coating. The corrosion resistance of the coated aluminum alloy in NaCl solution and the influence of surface treatments on corrosion resistance were investigated. Results showed that the efficiency of corrosion inhibition decreased with increasing corrosion time, with the sand powder film coating showing the highest inhibition performance and the ordinary heat-sealing oxidized coating showing the lowest. Corrosion performance rankings varied depending on the corrosion time and solution concentration.

Summary: Graphene synthesis via electrochemical methods, including deposition on Al foils and AlSi10MgCu particles, was studied. The pH values of electrolyte mediums were found to have a significant impact on the deposition of graphene layers. An increase in H2SO4 concentration led to the formation of thicker graphene layers on AlSi10MgCu particles.

Summary: Aluminum alloy workpieces are prone to corrosion problems during cutting, causing serious losses to the machining industry. This study investigated the effect of P. xiamenensis breeding in the cutting fluid on the corrosion of aluminum alloy 2219. The results showed that P. xiamenensis adhered to the surface of the alloy, forming uneven corrosion product film and biofilm. The presence of P. xiamenensis accelerated pitting corrosion and increased the corrosion rate of the alloy.
