“…37 The Raman mapping images of the solvent or ions in the electrolyte can also reflect the structure of the electrolyte to a certain extent. 38 Compared with the dispersion of NO 3 − in the 25 m WIS electrolyte (Figure S14a), NO 3 − and the AN diluent in the 10 m LWIS electrolyte are still evenly distributed (Figure S14b,c), further demonstrating that the LWIS electrolyte well inherits the original solvation structure of the WIS electrolyte.…”

“… With AN, the 1 H and 17 O signals of H 2 O present a downshift of the chemical shift (for example, 10 m LWIS electrolyte, 1 H: 4.21 ppm, 17 O: −8.51 ppm, Figure e,f) because of the formed hydrogen bond in the LWIS electrolyte, which further confirms the enhanced interaction between NO 3 – and H 2 O and the increased electron density around H 2 O (Figure S13).

Localized "water-in-salt" (LWIS) electrolytes are promising candidates for the next generation of high-voltage aqueous electrolytes with low viscosity/salt beyond high-salt electrolytes. An effective yet high-function diluent mainly determines the properties of LWIS electrolytes, being a key issue. Herein, the donor number of solvents is identified to serve as a descriptor of interaction intensity between solvents and salts to screen the organic diluents having few impacts on the solvation microenvironment and intrinsic properties of the original high-salt electrolyte, further leading to the construction of a novel low-viscosity electrolyte with a low dosage of the LiNO 3 salt and well-kept intrinsic Li + − NO 3 − −H 2 O clusters. Nonsolvating diluents, especially acetonitrile (AN) that has never been reported previously, are presented with the capability of constructing a LWIS electrolyte with nonflammability, electrode-philic features, lower viscosity, decreased salt dosage, and a greatly enhanced ion diffusion coefficient by about 280 times. This strongly relies on a huge difference of about 5000 times in coordination and solubility between AN and H 2 O toward LiNO 3 (0.05 vs 25 mol kg solvent −1) and the moderate interaction between AN and H 2 O. Multi-spectroscopic techniques and molecular dynamics simulations uncover the solvation chemistry at the microscopic level and the interplay among cations, anions, and H 2 O without/with AN. The identified unique diluting and nonsolvating effects of AN reveal well-maintained cation−anion− H 2 O clusters and enhanced intermolecular hydrogen bonding between AN and H 2 O, further reinforcing the H 2 O stability and expanding the voltage window up to 3.28 V. This is a breakthrough that is far beyond high-viscosity/salt electrolytes for high-voltage and high-rate aqueous supercapacitors.

To achieve a surface-enhanced Raman spectroscopy (SERS) sensor that is easy to make and use, we propose periodic gold nanotrench arrays, which can be fabricated without surface contamination and intricate sensor alignment. Deep and narrow plasmonic nanotrenches for amplifying local electromagnetic fields were reliably generated on a wafer-scale substrate by nanoimprint lithography and two successive oblique-angle depositions. Electromagnetic simulations and Raman measurements show that the proposed plasmonic nanostructures function as SERS sensors, enabling nanomolar sensitivity. Furthermore, we successfully confirmed the microRNA detection capability of the proposed nanostructures to demonstrate their promising potential and feasibility for use in biomedical diagnostic sensors.
