Summary: A highly sensitive nanoscale mass sensor was developed using a suspended graphene structure to measure the weight of single microparticles. The sensor consists of an array of holes covered with suspended monolayer graphene. By measuring the shift of the 2D Raman peak in graphene, the mass of microparticles in the suspended graphene can be determined. The sensor successfully detects microparticles with masses ranging from 0.1 ng to 3 ng. The concept demonstrated in this study holds promise for nano-mass measurement applications.

Summary: This article extends the method of lines (MoL) to analyze 2-D multilayer structures loaded with graphene plates in cylindrical coordinates. The admittance transformation matrices on all the planes of the multilayer structure are derived taking into account the tensor-form conductivity of the magnetized graphene plate. A technique to obtain the characteristic equation and propagation constant of the structure is proposed by matching the fields at the interfaces loaded with graphene. The proposed method is validated by comparing the results with COMSOL simulations and has potential applications in tunable microwave attenuators and phase shifters.

Summary: This article discusses a novel fabrication technique for producing suspended graphene field-effect transistors on a Si-substrate. Defects and chemical residues between the graphene and substrate can significantly degrade the electrical properties of the graphene channel. To minimize this degradation, a method of physically suspending the graphene while maintaining its structural integrity has been employed. By using a sandwich method, a suspended GFET with a fabrication yield of 76% has been achieved, higher than other methods. Additionally, the degradation of electrical properties due to external factors has decreased. Our mechanically stable method can be applied to fabricate electrical devices using various two-dimensional (2D) materials, making it useful for future device engineering. A large amount of electrically clean samples can be manufactured simultaneously, making it applicable to various applications.

Summary: Using a multifunctional viscoelastic polymer gel as a shock-free adhesive and dopant layer, a defect-free, etchant-free, wrinkle-free, and large-area graphene transfer method has been demonstrated. The thermally cured soft gel interacts with graphene through strong charge-transfer interaction and excellent shock absorption, allowing for direct mechanical exfoliation of graphene from the substrate without wrinkles. The transferred graphene layer shows high mechanical and chemical stabilities, making this gel-assisted mechanical transfer method a potential solution for large-scale graphene synthesis and next-generation electronics applications.

Summary: In this study, the physicochemical properties of III-VI and IV-VI metal chalcogenides in both bulk and nanosheets forms were investigated. Their potential applications in electrocatalysis, photocatalysis, and gas sensing were explored using density function theory and surface-science experiments. GaSe, InSe, and GeSe were identified as promising low-cost catalysts due to their stability in water and resistance against CO poisoning. Both bulk and exfoliated III-VI and IV-VI metal chalcogenides exhibited oxidation, resulting in the formation of an oxide skin. This self-assembled heterostructure enhanced the electrocatalytic activity of the materials. Additionally, the modified band gap due to oxidation enabled the activation of photocatalytic processes with different wavelengths. The self-assembled metal-oxide/metal-chalcogenide heterostructure also allowed for gas sensing of NO2, NH3, and CO at elevated temperatures. Overall, III-VI and IV-VI metal chalcogenides show great potential in electrochemistry, photocatalysis, and chemical sensing due to their low cost and superior application capabilities.

Summary: Metal spinel ferrites play important roles in magnetic, electrical and (photo-)catalytic device applications. The electrical conductivity of these ferrites can be controlled by tailoring their composition, degree of inversion, and non-stoichiometry. The substitution of Co for Zn in ZnFe2O4 ferrites significantly affects the activation energy and the type of hopping mechanism, depending on the atmospheric conditions. Our findings emphasize the importance of controlling non-stoichiometry for tuning the electrical properties of quaternary ferrites.

Summary: Cell migration plays a crucial role in physiological and pathological contexts, but its mechanisms are still not fully understood due to the complex interaction between cells and their surroundings. Traditional assays lack the ability to capture this complexity, while a novel approach using 2D micro-patterned substrates provides a promising tool to investigate cell migration in complex environments. The developed method was tested with breast cancer cell lines and revealed that invasive cells are more responsive to the size of the water meniscus and exhibit significative matrix deposition process connected to cell migration.

Summary: The chemical reactivity of cadmium diarsenide (CdAs2) towards ambient gases (oxygen and water) and air was assessed using density functional theory and experiments. The surface of CdAs2 forms an oxide skin, but its thickness remains nanometric even after one year in air. Therefore, future quantum devices based on Kramers-Weyl fermions could be stable in air, as the native oxide layer formed on chiral quantum materials actually protects their bulk features.

Summary: This study investigates the structural, electronic, magnetic properties, and chemical stability of a reactive metal, Europium, intercalated between a hexagonal boron nitride (hBN) layer and a Pt substrate. It is found that the intercalation of Europium leads to the formation of a hBN-covered ferromagnetic EuPt2 surface alloy with divalent Eu2+ atoms at the interface. The system is exposed to ambient conditions, and partial conservation of the divalent signal is observed, indicating the stability of the Eu-Pt interface. By using a curved Pt substrate, the changes in the Eu valence state and the protection against ambient pressure at different substrate planes are explored. The formation of the interfacial EuPt2 surface alloy remains consistent, but the resistance of the protective hBN layer to ambient conditions is reduced, likely due to surface roughness and discontinuous hBN coating.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
