abstract = {Water molecules at the solid-liquid interface display intricate
behaviors sensitive to small changes. The presence of different
interfacial components, such as cations or functional groups, shapes the
physical and chemical properties of the hydrogen-bond network.
Understanding such interfacial hydrogen-bond networks is essential for a
large range of applications and scientific questions. To probe the
interfacial hydrogen-bond network, atmospheric water capture is a
powerful tool. Here, we experimentally observe that a calcium ion on a
calcium-intercalated graphene oxide aerogel (Ca-GOA) surface captures
3.2 times more water molecules than in its freestanding state. From
experimental Van't Hoff estimation and density functional theory (DFT)
calculations, we uncover the synergistically enhanced hydrogen-bond
network of the calcium ion-epoxide complex due to significantly larger
polarizations and hydrogen bond enthalpies. This study reveals valuable
insights into the interfacial water hydrogen-bond network on
functionalized carbon-cation complexed surfaces and potential pathways
for future atmospheric water generation technologies.},

abstract = {Understating the mass transport via nanopores and nanochannels plays a
vital role in membrane-based separation systems and applications.
Graphene and its derivates, such as graphene oxide (GO) and reduced GO,
are one-atom-thick, 2D materials that exhibit outstanding physical and
chemical properties. Based on their fascinating features, graphene-based
materials have become important building blocks for 2D separation
membranes that with well-defined nanopores or nanochannels. In this
review, the mass transport through in-plane nanopores on nanoporous
graphene membranes and 2D nanochannels in GO-based laminar membranes are
discussed. The recent advances in nanoporous graphene engineering, as
well as separation applications, are discussed. The discussion of
GO-based membranes is unfolded from the structure and properties of GO
and nanochannels formed by GO laminates. Through the understanding of
GO-based membrane structures and separation performance, the mechanisms
of mass transport in the nanochannels of GO-based membranes are
revealed, and strategies for GO membrane modification are introduced and
summarized from both mechanism and application perspectives. This study
may provide a highly desirable guideline for future graphene-based
nanostructures and their applications in mass transport.
This review article explores recent advances in mass transport through
in-plane nanopores on graphene membranes and 2D nanochannels.
Additionally, this study summarizes modification strategies for graphene
oxide-based membranes, providing a comprehensive overview that serves as
a guideline for the development and application of 2D material-based
membranes for separation and purification.image (c) 2024 WILEY-VCH GmbH},

abstract = {Bottom-up electrochemical synthesis of atomically thin materials is
desirable yet challenging, especially for non-vanderWaals (non-vdW)
materials. Thicknesses below a few nanometers have not been reported
yet, posing the question how thin can non-vdW materials be
electrochemically synthesized. This is important as materials with
(sub-)unit-cell thickness often show remarkably different properties
compared to their bulk form or thin films of several nanometers
thickness. Here, a straightforward electrochemical method utilizing the
angstrom-confinement of laminar reduced graphene oxide (rGO)
nanochannels is introduced to obtain a centimeter-scale network of
atomically thin (<4.3 & ANGS;) 2D-transition metal oxides (2D-TMO). The
angstrom-confinement provides a thickness limitation, forcing
sub-unit-cell growth of 2D-TMO with oxygen and metal vacancies. It is
showcased that Cr2O3, a material without significant catalytic activity
for the oxygen evolution reaction (OER) in bulk form, can be activated
as a high-performing catalyst if synthesized in the 2D sub-unit-cell
form. This method displays the high activity of sub-unit-cell form while
retaining the stability of bulk form, promising to yield unexplored
fundamental science and applications. It is shown that while retaining
the advantages of bottom-up electrochemical synthesis, like simplicity,
high yield, and mild conditions, the thickness of TMO can be limited to
sub-unit-cell dimensions.},
