Mono-/multivalent ion-selective separation has become a common requirement at the water-
energy nexus, including energy storage and conversion, water purification, and sustainable …

Surface charge controls many static and dynamic properties of soft matter and
micro/nanofluidic systems, but its unambiguous measurement forms a challenge. Standard …

Liquid water confined within nanometer-sized channels exhibits a surprisingly low dielectric
constant along the direction orthogonal to the channel walls. This is typically assumed to …

Dielectric permittivity is central to many biological and physiochemical systems, as it affects
the long-range electrostatic interactions. Similar to many fluid properties, confinement …

The dielectric constant for water is reduced under confinement. Although this phenomenon
is well known, the underlying physical mechanism for the reduction is still in debate. In this …

In this study, we examine the spectral dielectric properties of liquid water in charged
nanopores over a wide range of frequencies (0.3 GHz to 30 THz) and pore widths (0.3 to 5 …

As a porous hydrophilic phase, C–S–H is expected to exhibit a frequency-dependent
dielectric response. This C–S–H property remains unknown, despite the importance of …

Water expands upon freezing. What happens when water is cooled below 0° C in an
undeformable, constant-volume container? This is a fundamental question in materials …

Despite considerable effort, the dielectric constant of interfacial water at solid surfaces is still
not fully understood, thus hindering our understanding of the ubiquitous physical …

The tunable polarity of water can be exploited in emerging technologies including catalysis,
gas storage, and green chemistry. Recent experimental and theoretical studies have shown …
