In recent years, lanthanum hydroxide (La (OH) 3) material has been widely applied in areas such as heterogeneous catalysis, materials, hydrogen storage materials, electrode materials, and superconducting materials. Its performance largely depends on particle size, aggregation, pore volume and surfac..... [Detail]
氧化是將石油化學基的原料轉化成更高氧化狀態的通用化學品的核心技術。然而,氧化反應對環境提出了一些極大的挑戰。許多工業氧化方法涉及重金屬或​​腐蝕性試劑,並且耗能高。例如,對苯二甲酸是前50種化學品之一,年產40萬公噸,也依賴於氧化反應。本發明的目的是, 在進行化學品生產過程中,通過避免使用有毒的試劑,減少或甚至避免使用揮發性有機溶劑, 同時提高能源效率, 盡量減少對環境的負面影響。綠色氧化草案已經成立,它可與現時行業所採用的技術媲美。一個很好的例子,證實進行對二甲苯的氧化生產苯二甲酸時, 可使用水作某介,而不涉及重金屬試劑。 [Detail]
本發明可應用於顯示器, 街燈, LCD背光, 照明系統等。本實用新型公開了一種有機電致發光器件(OLED), 摻雜熱穩定性高及傳輸能力佳的空穴注入材料,可降低器件的驅動電壓,提高發光效率, 且空穴注入層的厚度不影響器件的性能,從而減少由於氣化物透明陽極薄膜材料表面粗糙而對OLED器件壽命的影響. [Detail]
