abstract = {Selective electrochemical carbon dioxide reduction (CO2RR) requires
simultaneous control of catalytic reaction pathways, interfacial
chemistry, and reactant transport across multiple length scales. Here,
we engineer a hierarchical three-dimensional (3D) Cu/CuxO-carbon
electrode that integrates these functions within a single architected
platform. Oxidative stabilization followed by pyrolysis preserves the
printed macroporous lattice while generating a conductive nitrogen-doped
carbon framework, with 1.0 mm struts providing a practical balance
between structural integrity, electrochemical accessibility, and
resistance. Graphene oxide (GO) functionalization and subsequent
cathodic Cu deposition simultaneously produce a defect-rich reduced
graphene oxide (rGO) interface and size-tunable Cu/CuxO nanoparticles.
Product selectivity is governed by the coupled effects of Cu
nanoparticle size, potential, and electrolyte pH. Intermediate-sized Cu
nanoparticles (32 nm) achieve a Faradaic efficiency (FE) of 66.9% for
ethanol at -0.6 V versus the reversible hydrogen electrode (RHE) and pH
6.8, whereas increasing the pH to 7.5 redirects the reaction toward
formate. This selectivity is consistent with competition between the
*OCHO-mediated C1 pathway and *CO-mediated carbon-carbon coupling
toward ethanol. Reaction-diffusion simulations show that the 3D
architecture maintains a mean normalized surface CO2 concentration of
0.932, compared with 0.611 for a planar electrode, increasing transport
effectiveness by 52.4%. These results establish a multiscale
electrode-engineering strategy in which catalyst nanostructure controls
reaction branching, the rGO interface regulates catalyst integration,
and 3D architecture sustains reactant availability.},

abstract = {Carbon-based coatings are promising for biomedical implants, including
vascular stents, but fabrication on metals often requires adhesion
interlayers or polymer-assisted transfer, increasing cost and
complexity. Here, we report a simple, ambient-pressure chemical vapor
deposition (CVD) process for the direct, interlayer-free growth of two
carbon coatings on nitinol (NiTi) stents: few-layer graphene (FLG/NiTi,
170 +/- 20 nm) and amorphous carbon (a-C/NiTi, 620 +/- 30 nm). Both
coatings significantly enhanced corrosion resistance, with protection
efficiencies of 83.78% for FLG/NiTi and 89.19% for a-C/NiTi. Vascular
cell assays revealed distinct and clinically relevant biological
responses. a-C/NiTi promoted vascular endothelial cell (VEC)
proliferation (+17.2% at 96 h relative to bare NiTi) while suppressing
vascular smooth muscle cell (VSMC) proliferation (-25%), a desirable
outcome as excessive VSMC growth drives in-stent restenosis, whereas
endothelialization supports vessel healing. In contrast, FLG/NiTi
inhibited proliferation of both cell types (>50% reduction for VECs).
All samples exhibited excellent hemocompatibility (hemolysis < 0.2%),
and a-C/NiTi reduced platelet surface coverage by 30% compared with
bare NiTi, beneficial for mitigating thrombosis. Inflammatory assessment
further showed a 73% reduction in TNF-alpha secretion on a-C/NiTi in
comparison to bare NiTi. Together, these results demonstrate an
interlayer/ polymer-free route to carbon-coated NiTi stents with tunable
biological performance.},

abstract = {Here, we report a one-spot, temperature-controlled AC
electropolymerization strategy for converting graphene oxide and aniline
into a crystalline, processable reduced graphene oxide (rGO)/polyaniline
(PANI) composite for wearable ionic transistor textiles. By tuning the
electropolymerization temperature from 4 degrees C to 55 degrees C under
a low-frequency triangular AC waveform, followed by mild postreduction,
conformal polycrystalline PANI nanodomains are grown directly on rGO
sheets. Low-temperature synthesis yields the highest structural ordering
and the lowest fraction of protonated imine species, directly linking
growth conditions to mixed ionic-electronic transport behavior. The
resulting rGO/PANI composite functions as an electrolyte-gated
transistor with stable operation and amplified gate response.
Furthermore, the composite can be stencil printed onto cotton textiles
to realize ratiometric Na+/K+ sensing at constant ionic strength,
highlighting its potential for scalable, wearable ion-sensing
architectures.},

self-assembled graphene oxide (GO) core-shell microspheres as tunable

Electrochemically, the optimized architecture delivers 125 F g(-1), 1.4

after 30 000 cycles while preserving structural integrity. This method

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.},
