Abstract
Aqueous zinc-based energy storage devices possess superior safety, cost-effectiveness, and high energy density; however, dendritic growth and side reactions on the zinc electrode curtail their widespread applications. In this study, these issues are mitigated by introducing a polyimide (PI) nanofabric interfacial layer onto the zinc substrate. Simulations reveal that the PI nanofabric promotes a pre-desolvation process, effectively desolvating hydrated zinc ions from Zn(H2O)6 2+ to Zn(H2O)4 2+ before approaching the zinc surface. The exposed zinc ion in Zn(H2O)4 2+ provides an accelerated charge transfer process and reduces the activation energy for zinc deposition from 40 to 21 kJ mol-1. The PI nanofabric also acts as a protective barrier, reducing side reactions at the electrode. As a result, the PI-Zn symmetric cell exhibits remarkable cycling stability over 1200 h, maintaining a dendrite-free morphology and minimal byproduct formation. Moreover, the cell exhibits high stability and low voltage hysteresis even under high current densities (20 mA cm-2, 10 mAh cm-2) thanks to the 3D porous structure of PI nanofabric. When integrated into full cells, the PI-Zn||AC hybrid zinc-ion capacitor and PI-Zn||MnVOH@SWCNT zinc-ion battery achieve impressive lifespans of 15000 and 600 cycles with outstanding capacitance retention. This approach paves a novel avenue for high-performance zinc metal electrodes.

Abstract
![]()
Boron neutron capture therapy (BNCT)
is a binary therapeutic method
for cancer treatment based on the use of a combination of a cancer-specific
drug containing boron-10 (10B) and thermal neutron irradiation.
For successful BNCT, 10B-containing molecules need to accumulate
specifically in cancer cells, because destructive effect of the generated
heavy particles is limited basically to boron-containing cells. Herein,
we report on the design and synthesis of boron compounds that are
functionalized with 9-, 12-, and 15-membered macrocyclic polyamines
and their Zn2+ complexes. Their cytotoxicity, intracellular
uptake activity into cancer cells and normal cells, and BNCT effect
are also reported. The experimental data suggest that mono- and/or
diprotonated forms of metal-free [12]aneN4- and [15]aneN5-type ligands are uptaken into cancer cells, and their complexes
with intracellular metals such as Zn2+ would induce cell
death upon thermal neutron irradiation, possibly via interactions
with DNA.
