atomistic reference databases for GAP fitting have been developed either in a manual process (see, e.g., ref.61) or through GAP–RSS runs62,63—but these two approaches are inherently different, in many ways diametrically opposed, and it has not been fully clear what is the optimal way ...
This can be explained on the basis that the Th–P distances in 5 should be shorter than in 2 because the HP2 À carries a greater charge than since the dianionic charge of HP2 À is the H2P À unit. However, spread between two metals in 5 but only one metal in 3 it is ...
In addition, it can be assumed that a reformed emissions trading will trigger an increased use of N-fixing legumes to supply N to plants. Integrating legumes into diversified crop rotations has simultaneously a positive effect on the efficiency of P fertilization. P uptake by crops would be impr...
The Maumee River, which drains into the southwestern corner of the western basin, has the largest watershed of any river draining into the Great Lakes. Cropland occupies about 73% of the 16,388-km2 watershed upstream from the Waterville gaging station (Baker et al., 2014a), and it is the...
Red phosphorus (RP) has gained increasing attention in photocatalysis, because it is a cost-effective and earth-abundant semiconductor with a narrow bandgap [2]. However, the photogenerated carrier separation and migration efficiency of RP is low on account of severe charge recombination and absence...
A certain element has its outermost electron in a 3s subshell. It has valence +1 because it has 1 more electron than a certain noble gas. What element is it? a) Ar b) Ne c) Na d) Co e) HeFind the probability that the electron in the ground state of a...
The design of van der Waals heterojunctions with S-scheme charge transfer pathway is expected to be an effective strategy for improvement of photocatalytic performance. Herein, two-dimensional (2D) phosphorus-doped g-C3N4/Bi5O7I van der Waals heterojunctions with reduced graphene oxide as electron ...
But there is a key difference between the two materials – while BP has a natural band gap, graphene, in its pristine state, has a band gap of zero. POSTECH Professor Keun Su Kim, explains, ‘Because of this, one can flow current in graphene very efficiently, but it is extremely diffic...
Although wide-range, active and reversible tunability of the operating wavelengths in optoelectronic devices after fabrication is a highly desirable feature, no such platform has been yet developed. Here we demonstrate high-performance room-temperature infrared optoelectronics with actively variable spectra ...
In order to take into account the screening effect in BP films under different electric fields, we resorted to the nonlinear Thomas-Fermi theory, which has been applied to films of various materials to calculate the charge distribution and screening35,36,37,38. We also performed calculations of...
