科學英文問題描述 / 假設描述 (15) (上) : 研究生英文投稿日報 科學計劃建構 While consisting of dispersed oil globules containing small aqueous droplets, water-in-oil-in-water double emulsions (W/O/W) are extensively adopted in many product areas, including drug-delivery systems, cosmetics and food processing. 科學計劃問題 Although the internal phase is a perfect pool to protect active matter, double emulsion is a thermodynamically unstable system with a strong tendency for coalescence, flocculation and creaming. (NOTE : Add 2-4 sentences that describe characteristics of the problem or statistics that reflect its severity) 科學計劃問題的量化 Therefore, most double emulsions form a large droplet, making long-term storage impossible and release of the active matter uncontrollable. 科學計劃問題的中心 In practice, in addition to that double emulsion prepared with a monomeric emulsifier cannot provide long-term storage, a polymeric emulsifier can enhance the adsorbability of active matter, thus offering more stable conditions and release of properties in double emulsions. 科學計劃需求 Therefore, the inner/outer emulsion must be stabilized and the droplet size reduced by using a polymeric emulsifier, thus enhancing the stability of double emission. *科學提案建構 : 你科學提案的主題是什麼? 你的讀者可以明瞭科學提案的內容嗎? *科學問題 : 你的科學提案裡有你試著要解決或是想更進一步瞭解的問題嗎? *科學問題的量化 : 你要如何量化問題來讓你的讀者明白之前文獻研究所遇到的量化限制 ? *科學問題的中心 : 如果問題沒被解決或是充分瞭解, 這對科學提案的讀者會有多大的負面衝擊? *科學計劃需求 : 根據以上問題,最迫切的計劃需求是什麼? 研究生英文投稿日報: chineseowl.wordpress/
