abstract = {Segmented elastomers, such as polyurea, dissipate energy through various
mechanisms. Although dynamic stiffening of soft domains is often cited,
growing evidence highlights the dominant role of hydrogen-bond breaking
and reformation. To clarify the specific role of hard domains, we
synthesized polyurea, polyurethane, and polyurethane-urea with
systematically varied hard-domain order, while maintaining comparable
soft-domain dynamics at a target strain rate. Microballistic impact
experiments revealed two distinct dissipation regimes, with ordered
polyurea performing best. FTIR spectroscopy and strain-rate-dependent
cyclic tension experiments confirmed an order-disorder transition
coinciding with maximum energy dissipation. These findings emphasize the
role of ordered hard domains in elastomer design.},

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 = {The conversion of excess carbon dioxide (CO2) into valuable chemicals is
critical for achieving a sustainable society. Among various catalysts,
molybdenum disulfide (MoS2) has demonstrated potential for CO2
hydrogenation to methanol. However, its catalytic activity has yet to be
fully optimized, and scalable, industrially viable production methods
remain underdeveloped. In this work, a chemical vapor deposition (CVD)
approach is introduced to grow vertically oriented MoS2 crystals on an
amorphous carbon template. This method enhances the exposure of
vacancy-rich basal planes, which are crucial for stable catalytic
performance. The 2H-MoS2 flakes, supported on a conductive carbon
scaffold, exhibit catalytic activity, achieving a net space-time yield
of 2.68 g(MeOH) gcat(-)(1) h(-)(1) with a selectivity of 82.5% under
mild conditions (264 degrees C, 10 bar). This work highlights a
significant step toward the industrial application of MoS2-based
catalysts for CO2 conversion, bridging the gap between fundamental
research and scalable implementation.},

abstract = {Hydrogel devices with mechanical toughness and tunable functionalities
are highly desirable for practical long-term applications such as
sensing and actuation elements for soft robotics. However, existing
hydrogels have poor mechanical properties, slow rates of response, and
low functionality. In this work, two-dimensional hydrogel actuators are
proposed and formed on the self-assembly of graphene oxide (GO) and
deoxynucleic acid (DNA). The self-assembly process is driven by the
GO-induced transition of double stranded DNA (dsDNA) into single
stranded DNA (ssDNA). Thus, the hydrogel's structural unit consists of
two layers of GO covered by ssDNA and a layer of dsDNA in between. Such
heterogeneous architectures stabilized by multiple hydrogen bondings
have Young's modulus of up to 10 GPa and rapid swelling rates of 4.0 x
10-3 to 1.1 x 10-2 s-1, which surpasses most types of conventional
hydrogels. It is demonstrated that the GO/DNA hydrogel actuators
leverage the unique properties of these two materials, making them
excellent candidates for various applications requiring sensing and
actuation functions, such as artificial skin, wearable electronics,
bioelectronics, and drug delivery systems.
The self-assembly of single stranded deoxynucleic acid (ssDNA) and
double stranded (dsDNA) chains between graphene oxide (GO) nanolayers
endows the hydrogel membrane with robust mechanical and rapid swelling
properties. It can be employed to construct humidity and temperature
sensors and exhibits excellent self-healing properties, which has great
potential for wearable and healthcare devices. image},
