Enhanced penetration strategies for transdermal delivery

Qiaofei Pan, Yinglin Yu, Dong Chen, Genlong Jiao, Xiaowen Liu

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 3,   Pages 378-388 doi: 10.1007/s11705-019-1913-1

Abstract: Transdermal delivery offers several advantages in drug distribution, including convenience, painless administration, avoidance of first-pass metabolism, and ease of termination. However, the natural protective barriers of the skin, such as the stratum corneum, the topmost layer of skin, limit the systemic absorption of external therapeutics via transdermal delivery. Therefore, extensive application of transdermal delivery in medical treatment has been limited. Over the past few years, many formulation strategies and physical technologies, therefore, have been developed to enhance transdermal delivery. This review summarizes various formulation strategies proposed for transdermal delivery and their application in medical treatment.

In situ-based assessment of soil liquefaction potential–Case study of an earth dam in Tunisia

Ikram GUETTAYA,Mohamed Ridha EL OUNI

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 4,   Pages 456-461 doi: 10.1007/s11709-014-0259-5

Abstract: The present paper examines the evaluation of liquefaction potential of an earth dam foundation in Tunisia. The assessment of soil liquefaction was made using deterministic and probabilistic simplified procedures developed from several case histories. The data collected from the field investigation performed before and after the vibrocompaction are analyzed and the results are reported. The obtained results show that after vibrocompaction, a significant improvement of the soil resistance reduces the liquefaction potential of the sandy foundation. Indeed, in the untreated layers, the factor of safety drops below 1 which means that the soil is susceptible for liquefaction. However, in the compacted horizons, the values of exceed the unit which justifies the absence of liquefaction hazard of the foundation.

Semi-industrial Tests of Pressure Leaching on High-iron Sphalerite Concentrate

Wang Jikun,Zhou Tingxi,Wu Jinmei

Strategic Study of CAE 2005, Volume 7, Issue 1,   Pages 60-64

Abstract:

High-iron sphalerite was subjected to two-stage pressure leaching. The leaching rate of zinc and iron was 97.09 % and 15.2 % respectively. The yield of elemental sulphur was 93 % . The residual acid in the leachate was 3.95 g/L. By easy neutralization and purification, zinc sulphate solution was obtained, which would be sent to the zinc electrowinning operation. For the purpose of comparison, one-stage pressure leaching on average sphalerite was conducted. Leaching rate of zinc and iron was 98.09 % and 37.88 % respectively, and the yield of elemental sulphur was 96 % . The leachate with higher acid content (46.4 g/L) could be integrated into the existing traditional hydrometallurgical process of zinc
