Effect of PEDOT:PSS (Poly(3,4-ethylenedioxythiophene)-polystyrenesulfonate) Coating on Nanostructured Cobalt-Free LiNiMnO₂ Layered Oxide Cathode Materials for Lithium-Ion Battery.

Among cobalt-free layered oxides, Li(NiMn)O₂ ( ≤0.5) (LNMO) shows high reversible capacity, good cycling performance and thermal stability, and has relatively low cost and toxicity due to the absence of cobalt. In this study, we synthesized LNMO cathode materials having a porous fiber shape with primary particles that had an average diameter of about 328 nm.

Novel Composition of Co-Free LiNiMnAlO₂ Cathode Materials.

Ni-rich LiNiMnO₂ cathode materials have attracted widespread interest as promising alternative cathode materials owing to their higher capacity, lower cost, and lower toxicity compared to those of LiCoO₂. Therefore, we designed herein a LiNiMnO₂ positive electrode material. However, as the Ni content increases, the materials suffer from an extensive phase transition during the de-lithiation process owing to the low-bond strength of Ni (391.

Mitigation of Volume Expansion of Silica Anodes by Porous Titanium Dioxide Coating for Lithium-Ion Batteries.

Silica (SiO₂) is one of the most promising anode materials for LIBs due to its high theoretical capacity. However, the huge volume change of silica during the lithiation/delithiation processes is a disadvantage that results in poor electrochemical performance. In this study, the volume change of silica was effectively mitigated by coating the SiO₂ anode with porous TiO₂.

Production of sesaminol and antioxidative activity of fermented sesame with P8, ATCC 4356, S10.

This study was carried out to select the most competent bacterial cultures that could convert sesaminol glycosides to aglycone by β-glucosidase produced by lactic acid bacteria such as (LP), and in sesame fermented at 37°C for 24 h. The pH of fermented sesame was decreased compared to non-fermented controls. The pH of LP was lower than that of the other two during fermentation.

Improvement of operation lifetime in organic solar cell coated with diphenylacetylene polymer film.

To improve the operation lifetime of organic solar cell, two different diphenylacetylene polymers were tested as UV blocking layer. One of them showed either stronger UV absorption or a relatively intense fluorescence emission in the visible region which is well overlapped with the absorption of P3HT in the OSC. The diphenylacetylene polymer film significantly improved the operation lifetime of the OSC by efficiently absorbing the UV light, while reducing the UV-light energy loss to a minimum by converting the UV light to visible light through a down-conversion process.
