Abstract:
... Intrinsic dipole moment is an important characteristic of Janus single-layer MoSSe. Tuning the dipole moment would broaden the potential applications of Janus MoSSe in the field of piezoelectricity and molecular sensing. In this study, the dipole moments of Janus single-layer MoSSe with 3d transition-metal (TM) adatoms (Sc–Ni) are explored by using first-principles calculations. Our results demons ...

We combined a wet chemistry approach to synthesize metallic nanoparticles with a piezo-dispensing system enabling deposition of nanoparticles on the substrates with micrometer precision. In this way, an arbitrary patte ...

We have shown that an exchange dilution preparation method reduces the impact of surface adsorption of the target component in high-pressure gas mixtures used for underpinning measurements of amount-of-substance fraction. Gas mixtures are diluted in the same cylinder by releasing an aliquot of the parent mixture. Additional matrix gas is then added to the cylinder. This differs from conventional m ...

Recent fundamental study revealed that this dilemma could be addressed by discharging Li₂O₂ in the electrolyte solution rather than on the cathode surface. However, even for Li–O₂ batteries operated under the con ...
