Bulk liquid metals have prospective applications as soft and fluid electrical thermal conductors in electronic optical devices, composites, microfluidics, robotics, metallurgy with unique opportunities for processing, chemistry, function. Yet metals' great potential nanotechnology remains its infancy. Although work to date focuses primarily on Ga, Hg, their alloys, expand the field, we define "liquid metals" alloys melting points (mp) up 330 °C, readily accessible processable even using...
Differences in the extent of protonation functional groups lying on either side water–hydrophobe interfaces are deemed essential to enzymatic catalysis, molecular recognition, bioenergetic transduction, and atmospheric aerosol–gas exchanges. The sign range such differences, however, remain conjectural. Herein we report experiments showing that gaseous carboxylic acids RCOOH(g) begin deprotonate surface water significantly more acidic than supporting dissociation dissolved RCOOH(aq)....
The mechanism of proton transfer across water−hydrophobic media boundaries is investigated in experiments which the protonation gaseous n-hexanoic acid (PCOOH) upon collision with liquid water microjets monitored by online electrospray mass spectrometry as a function pH. Although PCOOH(aq) very weak base (pKBH+ < −3), PCOOH(g) converted to PC(OH)2+ on pH 4 via process that ostensibly retains some exoergicity its gas-phase counterpart, PCOOH + H3O+ = H2O, ΔG −22 kcal mol−1. large kinetic...
The reaction aimed at completing and closing the open cages of 1-decaboranethiol self-assembled monolayers (SAMs) on Au{111} with 4-phenyl-1-butyne results in highly ordered 4-phenyl-1-butyne. initially disordered 1-decaboranethiolate changed into (√3×√3)R 30° lattices typical alkyne SAMs, indicating complete substitution moieties, as determined by nanoscale imaging scanning tunneling microscopy X-ray photoelectron spectroscopy. Vibrational spectroscopy indicate that process happens...
Abstract Silver nanovines, prepared at ambient pressure and temperature, were grown in solution using eutectic gallium‐indium (EGaIn) seeds. In this process, EGaIn serves both as an effective reductant heterogeneous nucleation center enabling the selective growth of silver nanovines from aqueous nitrate solutions. This process is a versatile route towards grafted nanostructures performed under conditions with non‐toxic reagents.
