Volcano-type relationship between oxidation states and catalytic activity of single-atom catalysts towards hydrogen evolution

Nature Communications, 2022
While single atom catalysis offers high efficiency for materials use, different possible atomic configurations yield differing activities. Here, authors modulate single-atom Os coordinations to show a volcano relationship between oxidation state and H2 ...

Bi@Sn Core–Shell Structure with Compressive Strain Boosts the Electroreduction of CO2 into Formic Acid

Advanced Science, 2020
As a profitable product from CO2 electroreduction, HCOOH holds economic viability only when the selectivity is higher than 90% with current density (j) over −200.0 mA cm−2.

Stabilizing copper sites in coordination polymers toward efficient electrochemical C-C coupling

Nature Communications, 2023
Typically, Cu catalysts agglomerate under electrochemical conditions. Here, the authors report a coordination polymer catalyst with neighboring Cu sites which remain isolated and reduce CO2 to C2H4 with high selectivity and ...

Electrochemical deposition as a universal route for fabricating single-atom catalysts

Nature Communications, 2020
While single-atom catalysts exhibit intriguing catalytic performances and electronic structures, syntheses are often tailored to a particular system. Here, authors report electrochemical deposition as a universal approach for the fabrication of single ...

Phase diagrams of honeycomb and square nanocrystal superlattices from the nanocrystal's surface chemistry at the dispersion-air interface [PDF]

, 2019
In this work, we theoretically investigate the conditions favoring the interfacial self-assembly of PbSe nanocrystals (NCs) resulting in silicene-honeycomb superstructures.

Electrosynthesis of polymer-grade ethylene via acetylene semihydrogenation over undercoordinated Cu nanodots

Nature Communications, 2023
The removal of acetylene impurities remains important yet challenging to the ethylene downstream industry. Current thermocatalytic semihydrogenation processes require high temperature and excess hydrogen to guarantee complete acetylene conversion.

Adsorption trajectories and free-energy separatrices for colloidal particles in contact with a liquid-liquid interface [PDF]

, 2010
We apply the recently developed triangular tessellation technique as presented by J. de Graaf et al. [Phys. Rev. E 80, 051405 (2009)] to calculate the free energy associated with the adsorption of anisotropic colloidal particles at a flat interface. From

Polarization Modulation on Charge Transfer and Band Structures of GaN/MoS₂ Polar Heterojunctions

Crystals, 2023
As important third-generation semiconductors, wurtzite III nitrides have strong spontaneous and piezoelectric polarization effects. They can be used to construct multifunctional polar heterojunctions or quantum structures with other emerging two ...

Tuning colloid-interface interactions by salt partitioning [PDF]

, 2016
We show that the interaction of an oil-dispersed colloidal particle with an oil-water interface is highly tunable from attractive to repulsive, either by varying the sign of the colloidal charge via charge regulation, or by varying the difference in ...

Enhancement of Intracellular Calcium Ion Mobilization by Moderately but Not Highly Positive Material Surface Charges

Frontiers in Bioengineering and Biotechnology, 2020
Electrostatic forces at the cell interface affect the nature of cell adhesion and function; but there is still limited knowledge about the impact of positive or negative surface charges on cell-material interactions in regenerative medicine.
