Induced defect levels of P and Al vacancy-complexes in 4H-SiC: A hybrid functional study with P Si or P C and V C induced double donor levels, vacancy-complex formed with substitution of P and V Si induced negative-U charge state ... E Igumbor,O Olaniyan,RE Mapasha,... - 《Mater...
The well-designed process creates a CNT/CNF/Ni hybrid material. After a combination of chemical activation and acid treatment, an activated hollow CNT/CNF hybrid with a very high surface area of 1,840 m2 g−1 and a total pore volume of 1.21 m3 g−1 can be achieved (Fig. 5l). ...
Transition bias was observed in all the genes and 'G' to 'A' transitions were more favored than other form of transitions. Neutrality tests failed to show the presence of selection at these loci, though negative Tajima's D values ... B Waikhom,K Anirudh,MSK Reddy,... - 《Plos One》...
and therefore will not yield differing charge storage mechanisms. While workers have discussed systems like nanofibers as a structurally distinct class of materials, we do not agree with this stance due to a lack of direct evidence byXRD, HRTEM, Raman, ect. The findings are not mechanistically ...
3a, b), which can be attributed to the negative charge on the surface of the PUCC at neutral pH (Supplementary Fig. 6). The PUCC can function as both anode and cathode to assemble a symmetric full cell. The rectangular shape for the CV curves (Fig. 3c) and the nearly triangular ...
Using a dynamic computable general equilibrium (CGE) model, this paper examines the impact of different revenue-neutral carbon ETS policies on China’s economy, energy sectors, and environment, achieved through government subsidies and VAT reductions, with the overarching goal of achieving peak carbon...
We will implement energy conservation and carbon reduction projects in industrial parks, promoting systematic optimization of energy systems and cascading use of energy with a focus on industrial parks where energy-intensive, high-emissions projects are concentrated, so as to foster a group of energy-...
To alleviate negative externalities and reduce CO2 emissions produced by oceangoing vessels IMO enforced a number of regulations. In 2011, IMO developed a new chapter with amendments to MARPOL Annex VI, entitled as “Regulations on energy efficiency for ships” (IMO, 2017). According to those amen...
However, the presence of a negative charge (oxygen functionalities) and also the disordered lattice structure can hinder the formation of the semi-ionic C–F bond and LiF formation [340]. As the surface doping is more relevant for LIB, intercalation of fluorine to form semi-ionic C–F bonds...
In this study, based on density functional theory, we propose a new branch of pseudo-fullerenes which contain triple bonds with sp hybridization. We call these new nanostructures fullerynes, according to IUPAC. We present four samples with the chemical f
