We report a high voltage Zn–graphite dual-ion battery based on Zn(ClO 4 ) 2 water-in-salt (WiS) electrolyte with wide electrochemical window of 2.80 V and oxidative stability 2.60 vs. Zn/Zn 2+ .
Boron-doped diamond (BDD) interfaces were chemically functionalized through the catalyst free thiol-yne reaction. Different thiolated precursors (e.g., perfluorodecanethiol, 6-(ferrocenyl)-hexanethiol, DNA) successfully "clicked" to alkynyl-terminated BDD by irradiating interface at 365 nm for 30 min. Thiolated oligonucleotide strands immobilized using optimized reaction conditions, and surface concentration was tuned obtain a coverage of 3.1 × 10(12) molecules cm(-2). Electrochemical...
In this article, we report on the low-level detection of hydrogen peroxide, a key player in redox signaling pathway and toxic product cellular system, using colorimetric solution assay. Amine-terminated undoped nanocrystalline diamond thin films were grown glass linear-antenna microwave plasma CVD process. The surface consists mainly -NH(2) termination. aminated was decorated with horseradish peroxidase (HRP) enzyme carbodiimide coupling chemistry. success HRP immobilization confirmed by...
An atmospheric pressure dielectric barrier discharge burning in nitrogen with a small admixture of hexamethyldisiloxane (HMDSO) was used for the deposition thin organosilicon films. The films were deposited on glass, silicon and polycarbonate substrates, substrate temperature during process increased up to values within range 25–150 °C order obtain hard SiO x -like properties studied by means optical emission spectroscopy electrical measurements. characterized Rutherford backscattering...
The ability to protect materials from fire is vital many industrial applications and life safety systems. Although various chemical treatments protective coatings have proven effective as flame retardants, they provide only temporary prevention, do not change the inherent flammability of a given material. In this study, we demonstrate that simple microstructure can significantly boost resistance an atomically thin material well above its oxidation stability temperature. We show free-standing...
The magnitudes of the surface band bending have been determined by X-ray photoelectron spectroscopy for polar, semipolar, and non-polar surfaces wurtzite GaN crystals. All prepared from crystalline samples grown hydride-vapour phase epitaxy separated sapphire substrates. Ga 3d core level peak shifts used determination. Small also relatively small difference between bendings with opposite polarity found. These results point to presence electron states different amounts types on confirm...
AlGaN-based heterostructures are promising candidates for the fabrication of ultraviolet light-emitting diodes. The analysis atomic composition grown epitaxial films is important from a technological point view, allowing precise control over wavelength and intensity emitted light. In this work, depth profiling AlN(0001), AlGaN(0001), AlGaN quantum dot surfaces by molecular beam epitaxy was carried out using angle-resolved x-ray photoelectron spectroscopy (XPS) combined with Ar gas cluster...
To obtain quantitative information about the composition and bonding of atoms located at beyond analyzed solid surface nondestructively, we applied angle-resolved X-ray photoelectron spectroscopy aided by maximum entropy method to air-exposed amorphous carbon nitride films deposited pulsed laser deposition diamond-like modified low-energy nitrogen ion bombardment during film growth. We demonstrate that composition, chemical bonding, mass density vary significantly from top a shallow...
Spin Seebeck effect has been investigated in Pt/$\varepsilon$-Fe$_2$O$_3$ bilayers. The $\varepsilon$-Fe$_2$O$_3$ thin layer with $40-70$~nm thickness were deposited by a spin-coating method on Y:ZrO$_2$(100) substrates. prepared layers are highly oriented the easy magnetic $a$-axis parallel to film surface. hysteresis loops measured at room temperature field exhibit coercive fields up 11.6~kOe, which is so far highest value for samples. shape of spin similar magnetization single phase...
