Theoretical Study of Dissolved Gas Molecules in Transformer Oil Adsorbed on Intrinsic and TM (Ta, V)-Doped MoTe Monolayer.

In this paper, CH, CH, H, and CO adsorbed on intrinsic MoTe monolayer and transition metal atom (Ta, V)-doped MoTe monolayer have been investigated with density functional theory based on first-principles study. The adsorption energy, geometries, band structures, and density of states of four gases (CH, CH, H, and CO) adsorbed on the MoTe and doped MoTe surfaces were analyzed. The results shown that the gas adsorption performance of transition metal atom (Ta, V)-doped MoTe monolayers is more superior than that of intrinsic MoTe, and the adsorption energy and charge transfer of the adsorbed gases on the TM-MoTe monolayer are significantly increased in comparison with both sides.

Study on the Attenuation of Long-Term Skid Resistance of Asphalt Mixtures under Aeolian Sand Conditions.

In this work, the long-term skid resistance attenuation law of asphalt mixtures in the presence of aeolian sand was studied. Four types of asphalt mixtures underwent skid resistance abrasion tests using an accelerated loading tester. The pendulum value (BPN) and structure depth (MTD) of these four mixtures were determined under various conditions of sand density and abrasion times.

Effects of firefighting gloves styles on manual performance.

This study analyzes structural characteristics of firefighting gloves from the perspective of style design, to investigate the impact of the fit of four types of selected firefighting gloves on firefighters' manual operation efficiency. Seventeen male college students participated in the ergonomic trial to compare manual work done with bare hands and while wearing gloves. The results showed that the participants' hand dexterity decreased after wearing firefighting gloves, but there were significant differences between different styles of gloves.

Synthesis of carboxymethyl cellulose-chitosan-montmorillonite nanosheets composite hydrogel for dye effluent remediation.

MMTNS were introduced into carboxymethyl cellulose-chitosan system to synthesize porous hydrogel adsorbent with stable structure and high dye handling capacity. Al-OH on edge of MMTNS formed hydrogen-bond (-OH···NH-) with -NH on CS, CS then cooperated with CMC via amidation and chains interleaving, forming three-dimensional hydrogel. Morphology characterization revealed that hydrogel possessed microporous open-framework structure, facilitating free entrance of macromolecular MB dye to react with internal reaction sites in hydrogel.

Adsorption toward Cu(II) and inhibitory effect on bacterial growth occurring on molybdenum disulfide-montmorillonite hydrogel surface.

Novel molybdenum disulfide-montmorillonite (MoS@2DMMT) hydrogels for Cu(II) removal and inhibition on bacterial growth were successfully prepared. MoS was first in-situ growth onto 2DMMT platelet through hydrothermal method and then cross-linked with organic reagents to form hydrogels. The flower-like structure of synthesized MoS could be clearly observed in MoS@2DMMT by SEM.

The Potential Application of BAs for a Gas Sensor for Detecting SO Gas Molecule: a DFT Study.

Different atmospheric gas molecules (e.g., N, O, CO, HO, CO, NO, NO, NH, and SO) are absorbed on the pristine hexagonal boron arsenide (BAs) through density functional theory calculations.
