現今農業主流的「慣行農法」是以科技為基礎,促使農作物增加產量、具抗病力、成長期短的耕作方式,再透過施行化學肥料、殺蟲劑、農藥與大規模灌溉系統所嚴格控制的環境下,使作物獲得穩定的生長。然而這種優化農作物的生產方式是有其時代背景與精神,在十九世紀時,人類的糧食供給主要依賴天候,天然氮肥的產量有限,導致世界人口的成長受到限制,如何使糧食增產成為當時一大問題。德國化學家哈伯利用氫和空氣的氮在高溫高壓下轉換成氨,找到了人造肥料的合成法,為農業提供了源源不絕的氮肥並使作物得以增產,並且解決人口劇增所引發的糧食危機。
色彩斑斕的污泥,看在一般人眼裡,怵目驚心,但在美商世界資源眼裡,卻是大把大把的鈔票。 世界資源進入台灣,讓高科技業產生的「環保負擔」,翻身成有價資源。
The principal merit of the developed technology is the fact that the combustion synthesis yields a sintered matrix of the desired shape (hollow cylinders or spheres, plates), pore structure, and phase and chemical composition, which could be used without any additional processing. To obtain the synthesized materials with desirable macroporous...

Alzheimer's and Parkinson's disease are the two most common neurodegenerative disorders. They develop after a progressive death of many neurons in the brain. Although therapies are available to treat the signs and symptoms of both diseases, the progression of neuronal death remains relentless, and it has proved difficult to slow or stop. Hence,...
