abstract = {Controlling bending in two-dimensional (2D) materials is essential for
the development pf responsive systems and miniaturized actuators.
Traditional approaches, particularly for graphene oxide (GO), rely on
mismatched thermal expansion between GO and its reduced form. Here, we
report a scalable method for assembling anisotropic membranes with
chemically distinct top and bottom surfaces, achieved through
pH-programmed control of flake protonation. Actuation is driven by
edge-to-edge interactions among GO and MXene (Ti3C2Tx) flakes, where
differential protonation induces localized strain and in-plane flake
sliding during thermal dehydration. This gradient in charged and neutral
functional groups enables directional bending upon mild heating.
Extending this approach to MXenes yields robust, low-dimensional
actuators with tunable chemical and mechanical properties. Demonstrated
applications include soft robotics and climate-adaptive architecture.
Systematic analysis of thermal response, water retention, and
fabrication scalability underscores the broad potential of this platform
for 2D material-based devices.},

abstract = {Graphene oxide (GO) membranes offer high selectivity and
energy-efficient gas separation. However, their dense, layered structure
and tortuous diffusion paths limit permeability, posing a barrier to
industrial use. Here we present a method to enhance selectivity and
permeability, maintaining the structural stability of such membranes.
With an industrially friendly manufacturing method, we produce crumpled
GO membranes with gas diffusion pathways controlled by a multidomain
structure. These membranes achieve H2 permeability of approximately 2.1
x 104 barrer, significantly surpassing the permeability of flat lamellar
GO membranes, which is below 100 barrer. Its H2/CO2 selectivity of 91
outperforms current membrane technologies. In addition, the crumpled
membranes demonstrate stability under harsh conditions (-20 degrees C,
96% relative humidity), a critical requirement for practical
applications. This work addresses the long-standing
permeability-selectivity trade-off and establishes a robust, scalable
platform for integrating two-dimensional materials into membrane
technology for real-world applications.},

abstract = {Selective anion transport is essential for energy conversion, water
purification, and electrochemical systems, yet achieving precise ion
selectivity in membranes remains a challenge. Here, we present an
amino-functionalized graphene oxide (am-GO) membrane that enables
tunable anion transport through nanochannels. Using a combined
experimental and computational approach, we consider the three stages of
ionic transport-absorption, diffusion, and desorption-to reveal that Cl-
selectively diffuses through nanochannels, while NO3-, SO42-, and PO43-
are excluded. In ionic mixtures, the chemical transistor effect emerges,
where Cl- pulls water from NO3- hydration shell, enhancing its mobility,
while SO42- and PO43- remain excluded due to size constraints. This
mechanism enables precisely regulated Cl- and NO3- transport, with
ultrahigh rejection rates of 99.99% for SO42- and PO43-, even in
complex ionic environments. The am-GO exhibits stability and
anion-hopping mechanisms, making it a versatile platform for anion
exchange membranes in electrolysis, energy storage, and environmental
applications.},

abstract = {A promising way to address modern environmental and energy supply
challenges is via rapid implementation of decarbonization and hydrogen
production technologies. Development of gas separation membranes with
high selectivity and permeability is essential for these processes but
is still a bottleneck. Our research focuses on achieving precise control
of gas diffusion pathways through on -demand regulation of material
interactions in thin composite membranes. We combine 2D covalent organic
frameworks (COFs) and graphene oxide (GO) to create COF-GO composite
membranes with desirable nanosheet stacking, controllable thicknesses
and pathways for gases. By pH -assisted self -assembly, we fine-tune
material interactions and achieve simultaneous enhancement of
permeability and selectivity by increasing membrane thickness and
regulating the interactions between COF and GO nanosheets by pH. At a
thickness of 1.3 mu m, the COF-GO membrane, assembled under pH 4,
demonstrates good working characteristics for H2/CO2 equimolar mixture
(at room temperature and 1 bar), with a H2 permeability of 366 Barrer,
selectivity of 15.6, and long-term stability exceeding 200 h. This work
paves the way for tailored, performing gas separation with long-term
stability. It guides the unique 2D transport mechanism to be utilized
under practical conditions. Our research offers a novel strategy for the
design of composite membranes from two-dimensional (2D) materials for
gas separation technologies. It contributes to sustainable
decarbonization and hydrogen production solutions, bringing us closer to
a greener, more environmentally friendly future.},

interfacial problems encountered in composite counterparts, such designs
offer selfadaptive materials for smart housing and green architecture,

blade coating to a highly concentrated nematic GO suspension, we
successfully fabricate GO films with morphological gradient and

utilizing scanning electron microscopy (SEM) images for the
characterization of materials with macroscopic surface morphology.
Furthermore, we explore the application of these GO films as
low-dimensional soft actuators, revealing their outstanding
stimuli-responsive performance and self-adaptation to environment. Such
robust and flexible films can be used as integral building elements in
the bioinspired design of sustainable smart housing facilitating remote
robotization and sensing capabilities.},
