Summary: This study investigates the electron transfer processes in methylene blue-CdTe and methylene blue-CdTe/CdSe complexes. The research finds that the growth of the shell accelerates the electron transfer rate and changes the shape of the quantum dots. Transient absorption measurements show that QDs with a thin shell can achieve charge carrier multiplication, leading to increased charge transfer efficiency.

Summary: Carbohydrate antigen 15-3 (CA15-3) is an important biomarker for early diagnosis of breast cancer. In this study, a label-free electrochemical immunosensor was built using urchin-like core-shell Au@PdCu nanocrystals (labeled Au@PdCu NCs) for highly sensitive detection of CA15-3. The Au@PdCu NCs synthesized by a simple one-pot wet-chemical approach demonstrated exceptional catalytic properties for anchoring more antibodies and amplifying the signal. The developed biosensor exhibited a wide linear detection range and a low limit of detection for determination of CA15-3 under the optimal conditions.

Summary: A new tellurium and mercury containing macrocycle was synthesized via (2+2) condensation reaction and exhibited an unsymmetrical figure-of-eight conformation in the crystal structure. The resulting silver complexes showed intramolecular Hg...Ag and Te...Ag interactions as well as intermolecular Hg...Hg interactions, forming an extended 1D molecular chain in a non-linear manner. Solution studies using Hg-199 and Te-125 NMR spectroscopy, absorption, and emission spectroscopy further investigated the behavior of Hg...Ag and Te...Ag interactions. DFT calculations, AIM analysis, NCI, and NBO analysis supported the experimental findings and revealed the stronger intermolecular Hg...Hg interaction compared to the intramolecular Hg...Ag interactions.

Summary: An effective method has been developed to tune the intensity of surface-enhanced Raman scattering (SERS) of non-electroactive molecules by electrochemical means, involving the formation of nanostructures between Au@Ag core-shell nanoparticles and a gold nanoelectrode. The tuning is achieved by transforming the chemical composition of the thin Ag shell from metallic Ag to insulating AgCl, instead of introducing molecular changes by the electrode potential. The electrode potential can also tune the electromagnetic enhancement (EME) and specific Raman bands associated with Ag-molecule interaction in the Au@Ag nanostructures.

Summary: Rechargeable magnesium batteries (RMBs) are a promising energy-storage technology, but the development of high-performance cathode materials is a major challenge. This study demonstrates the high performance of ammonium tetrathiomolybdate as an RMB cathode material, which forms an amorphous structure with efficient magnesium-storage active sites and open transport pathways through ammonium extraction. The covalent-like molybdenum-sulfur bond weakens the interaction with magnesium ions and promotes simultaneous redox of molybdenum and sulfur, leading to high capacity.

Summary: In this study, a modified co-precipitation method was used to synthesize highly crystallized Prussian Blue analogs (PBAs). By introducing zinc as an electrochemical inert element to substitute high-spin iron, a highly reversible phase transition process for sustainable sodium-ion storage was achieved, resulting in improved cycle stability and specific capacity. In-situ tests confirmed minor lattice distortion and highly reversible phase transition of the zinc-substituted PBA during sodium-ion insertion and extraction, which greatly influenced the cycling stability. The zinc-substituted PBA exhibited remarkably enhanced cycling performance with a capacity retention of 58.5% over 2000 cycles at 150 mA g(-1) and superior rate performance up to 6000 mA g(-1).

Summary: In this study, a new dual-ion-in-sequence intercalation strategy is proposed to address the structural instability and sluggish diffusion kinetics of vanadium oxides in ZIBs. The Zn2+ storage mechanism evolves from solid-state ion diffusion kinetic into intercalation pseudocapacitance, resulting from the enlarged interlayer spacing. The improved ionic diffusivity, intercalation pseudocapacitance, and fast charge transferability contribute to the impressive rate capability and cycling stability of the ZIBs.

Summary: Liquid metal battery is a promising battery technology for grid energy storage, but it requires preheating to a high temperature before operation. This paper proposes an efficient thermal management controller design to optimize temperature uniformity and energy consumption. Experimental results show a controller error of 1.2%. A preheating strategy is further proposed to achieve the optimal balance between temperature uniformity and energy consumption, reducing the maximum temperature difference by 13.7% to 49.85 degrees C and energy consumption by 6.7% to 6.33 kWh.
