Bandgap engineering of graphene is an essential step toward employing in electronic and sensing applications. Recently, nanoribbons (GNRs) were used to create a bandgap function as semiconducting switch. Although GNRs with widths <10 nm have been achieved, problems like GNR alignment, width control, uniformity, high aspect ratios, edge roughness must be resolved order introduce robust alternative technology. Here we report patterning, characterization, superior chemical ultranarrow aligned...

Abstract As the demand for sustainable energy solutions grows, developing efficient conversion and storage technologies, such as fuel cells metal-air batteries, is vital. Oxygen Reduction Reaction (ORR) a significant limitation in electrochemical systems due to its slower kinetics. Although Pt-based catalysts are commonly used address this challenge, their high cost suboptimal performance remain obstacles further development. This review offers comprehensive overview of advanced support...
Abstract Water electrolysis, a key enabler of hydrogen energy production, presents significant potential as strategy for achieving net‐zero emissions. However, the widespread deployment water electrolysis is currently limited by high‐cost and scarce noble metal electrocatalysts in evolution reaction (HER). Given this challenge, design synthesis cost‐effective high‐performance alternative catalysts have become research focus, which necessitates insightful understandings HER fundamentals...
In this paper, the Kozeny–Carman constant of fibrous porous media is simulated by Fractal-Monte Carlo technique. The proposed probability model obtained based on fractal distribution pore size in media, and thus can be expressed as a function structural parameters including porosity, micro-pore size, fiber diameter, tortuosity dimension area pores. Our results demonstrate that increases with diameter. also illustrate satisfying agreement Fractal Monte-Carlo simulations existing experimental...
Integrating polyaniline (PANI) with two-dimensional (2D) nanostructures is a promising strategy to improve electrochemical performance. In this work, 2D laminar van der Waals heterostructures of graphene and WS2 nanosheets were prepared for the enhancement supercapacitive performance PANI. With well-dispersed graphene/WS2 nanosheet hybrids (G-LS/WS2-LS) as deposition supports, in situ polymerization aniline delivered ternary nanocomposite PANI/G-LS/WS2-LS. Benefiting from good electrical...
We report pronounced magnetoconductance oscillations observed on suspended bilayer and trilayer graphene devices with mobilities up to 270,000 cm2/Vs. For devices, we observe conductance minima at all integer filling factors nu between 0 -8, as well a small plateau {\nu}=1/3. features nu=-1, -2, -3 -4, {\nu}~0.5 that persist 4.5K B=8T. All of these for accessible values Vg B, could suggest the onset symmetry breaking first few Landau (LL) levels fractional quantum Hall states.
We present a lithography-free technique for fabrication of clean, high quality graphene devices. This is based on evaporation through hard Si shadow masks, and eliminates contaminants introduced by lithographical processes. demonstrate that devices fabricated this have significantly higher mobility values than those obtained standard electron beam lithography. To obtain ultra-high devices, we extend to fabricate suspended samples with mobilities as 120 000 cm2/(V·s).
We fabricate and investigate high-quality graphene devices with contactless, suspended top gates demonstrate the formation of pnp junctions tunable polarity doping levels. The device resistance displays distinct oscillations in npn regime, arising from Fabry–Perot interference holes between two pn interfaces. At high magnetic fields, we observe well-defined quantum Hall plateaus, which can be satisfactorily fit to theoretical calculations based on aspect ratio device.
