The excitation of the lowest electronic states and vibrational cytosine (C) have been studied using electron energy loss spectroscopy (EELS, 0–100 eV) with angular analysis. singlet found to be in good agreement UV-VIS absorption results on sublimed films, slightly blueshifted by about 0.1 eV. EEL spectra recorded at residual below 2 eV show clear shoulders losses 3.50 4.25 (±0.1 eV). They are assigned triplet cytosine. Energies molecular structures lowest-lying state C its methylated...
Abstract This work focuses on the two most common techniques, including direct contact method (CM) and electrochemical (EM) in half‐cell applied for SiO 2 /C anode. After prelithiation process, anodes would be assembled coin cells paired with NMC622 cathode. According to performance, techniques could strengthen initial discharged capacity Coulombic efficiency. While nonprelithiated sample exhibits a poor of 48.43 mAh·g − 1 low efficiency 87.41% first cycle, CM EM methods illustrated better...
Ionic liquid-based electrolytes proved to be effective in terms of alleviating the safety problems associated with lithium/sodium ion batteries, especially for large-scale applications, due their superior thermal stability and nonflammability. The main disadvantage ionic liquids is relatively high viscosity. Adding a suitable amount organic “thinning” solvents could potential solution this problem: while electrolyte viscosity greatly reduced, electrochemical properties remain almost as good...
Multireference complete active space self-consistent-field CASSCF(10,12)/ANO and second-order perturbation theory MS-CASPT2 calculations were performed to determine the vertical low-lying singlet triplet states of aniline. The sequence seven lower lying is T1(13A'), T2(13A' '), T3(23A'), T4(33A'), T5(23A' T6(43A'), T7(33A' '). 33A', 43A', 33A' ' are assigned as 3s, 3py, 3pz Rydberg states, respectively, while other correspond π* ← π excitations. Both T1 T2 found be below at lowest-lying S1...
This research work demonstrates a novel hybrid electrolyte based on deep eutectic solvent (DES) combined with organic solvents for high-performance supercapacitors. DES was formed between ethylene glycol (EG) and lithium bis((trifluoromethyl)sulfonyl) imide (LiTFSI) diluted by carbonate (EC) or acetonitrile (AN) different amounts (10–50% wt.). Such combination gives superior properties electrolytes compared to pure DESs reduces the volatility of mixed solvents. Regarding electrochemical...
Abstract Ionic liquids (ILs) have been considered as an alternative class of electrolytes compared to conventional carbonate solvents in rechargeable lithium/sodium batteries. However, the drawbacks ILs are their reducing ionic conductivity and large viscosity. Therefore, mixtures alkyl with IL a sodium bis(trifluoromethane sulfonyl)imide (NaTFSI) investigated develop new for sodium‐ion In this work, N‐Butyl‐N‐methylpyrrolidinium bis(trifluoro‐methanesulfonyl) imide (Py 14 TFSI) was used...
Various non-invasive methods have been studied for assessing the fibrosis stage in patients with chronic hepatitis B. However, performance of APGA, Fibrosis index diagnosing liver remains unclear globally and specifically Vietnam.
Abstract The progressive improvement in the gravimetric energy density of lithium‐ion batteries (LIBs) leads to electrolyte design, positive electrode, and full‐cell optimization processes. spinel lithium nickel manganese oxide (LiNi 0.5 Mn 1.5 O 4 , LNMO) is one potential candidates for next generation LIBs applied electric vehicles due high working (4.75 V vs. Li + /Li), affordable price, environmental friendliness. Nevertheless, degradation cycling performance at induces massive...
Nowadays, a hybrid composite SiO2/C has been paid attention to improving battery performance in Li-ion batteries (LIBs) as the anode. However, this material unexpectedly suffers from initial active lithium loss caused by solid electrolyte interface (SEI) formation leading low Coulombic efficiency and significantly reducing capacity. In order solve these issues, pre-lithiation considered an effective approach limit increase cycling performance. This work focuses on two most common techniques,...
