Unlocking Stability: The Crucial Role of Thermal Analysis in Lyophilization Temperature Optimization

The method of drug delivery significantly influences the final stages of the manufacturing process. Currently, lyophilization—a widely adopted technique—enables drug developers to stabilize formulations and therapeutic molecules using a validated commercial approach. In this process, precise control of pressure and temperature within a lyophilizer facilitates the removal of liquids from formulations containing thermally sensitive or hydrolytically unstable active pharmaceutical ingredients or formulation components.

Characterization Considerations when Sourcing PCR

Against the backdrop of a plastic waste crisis, the global demand for plastic is set to quadruple by 2060. This has driven a shift toward sustainability and away from linear use models of plastic production. Post-consumer resin (PCR) has emerged as a key player in circular economy initiatives, though ensuring the quality and performance of PCR requires several characterization considerations.

微量熱法的歷史

在整個 18 世紀,許多科學家都對熱的本質提出了質疑。艾薩克·牛頓 (Isaac Newton) 認為熱能是透過粒子的震動傳遞的,而勞勃·虎克 (Robert Hooke) 則認為熱能是人體各部位運動而產生的一種特性1。然而,在歷史上第一個眾所周知對熱量進行測量的貢獻者是蘇格蘭醫生和化學家約瑟夫·布拉克 (Joseph Black)1。1761 年,他透過精確的測量發現,對達熔點的冰或達沸點的水施加熱量並不會導致溫度變化1。這個觀察結果使他成為第一個區分溫度和熱量的科學家,標誌了熱力學的開端。
