As underwater missions become more and more complex, novel underwater manipulators with better performance are demanding. Soft underwater manipulators are judged to be the development direction and expected to have better performance in safe and compliant interaction with the target in underwater operations such as biological sampling. This paper provides an overview on the state-of-the-art of both hard and soft underwater manipulators to give a prospect for soft underwater manipulators. Key technologies in the design of soft underwater manipulators are identified, including the configuration design, actuator design and stiffening design of them.

“…Hasil scanning larutan klorofil diperoleh spektrum klorofil yang memiliki puncak pada panjang gelombang 410 nm dan 664 nm. Hasil ini sesuai dengan klorofil standar [24], sehingga untuk pengukuran konsentrasi klorofil digunakan nilai absorptivitas molar klorofil standar ini. Konsentrasi larutan ditentukan berdasarkan persamaan Hukum Lambert-Beer (Persamaan 1), dimana Ɛ merupakan absorptivitas molar klorofil berdasarkan referensi klorofil standar yaitu 78,75 x 10 3 Lmol -1 cm -1 , absorpsi (A) diperoleh dari hasil pengukuran, sehingga diperoleh nilai konsentrasi (c).…”

Zink oksida merupakan oksida logam semikonduktor yang telah banyak diteliti secara luas aplikasinya. Partikel ZnO berukuran mikro hingga nanometer dapat disintesis dengan penambahan capping agent, yaitu senyawa yang berperan mencegah terjadinya aglomerasi partikel. Pendekatan green synthesis ZnO dalam penelitian ini bertujuan untuk mengetahui pengaruh penambahan klorofil dari daun suji sebagai capping agent dengan variasi konsentrasi terhadap karakteristik (serapan infra merah, ukuran kisi kristal dan energi celah pita) ZnO yang dihasilkan. Sintesis ZnO dilakukan dengan prekursor zink nitrat, penambahan larutan ammonium hidroksida dan klorofil (Chl) dengan konsentrasi bervariasi (Chl 1= 19,60x10-6M; Chl 2= 2,45x10-6M dan Chl 3= 0,15x10-6M). Sintesis dilakukan secara hidrotermal dalam autoclave yang dipanaskan pada temperatur ±150oC dan ±180oC. Pertumbuhan kristal ZnO terjadi saat proses kalsinasi selama 3 jam pada temperatur ±400oC. Zink oksida hasil sintesis menunjukkan puncak serapan IR pada bilangan gelombang 447,49 cm-1 dan 601,79 cm-1, yang khas untuk vibrasi ulur Zn-O. Difraktogram XRD menunjukkan puncak-puncak kristal ZnO dengan struktur hexagonal wurtzite pada 2 sekitar 31°, 34°, 36°, 47°, 56°, 62°, 68 dan 89°. Ukuran kristal ZnO terkecil adalah 22,80 nm, yaitu ZnO dengan penambahan Chl 1. Nanopartikel ZnO hasil sintesis dengan penambahan Chl 1 menghasilkan nilai energi celah pita 3,29 eV, sedangkan energi celah pita ZnO kontrol yaitu 3,25 eV. Morfologi permukaan ZnO menunjukkan terjadinya aglomerasi. Berdasarkan penelitian, diperoleh bahwa penambahan Chl 1 dalam sintesis ZnO menghasilkan ZnO nanokristal dengan energi celah pita terbesar.

“…Therefore, the success of an extant or potential application of a drug delivery system innately depends on the choice of the drug carrier. [1][2][3][4] Researchers have considered numerous carriers over the past few decades, 5,6 and micro and nanofibers have become an attractive prospective carrier option. [7][8][9][10][11][12][13] This could be attributed to both the nature of the material used to fabricate the fiber and the nature of this very fabrication process.…”

The goal of drug delivery is to ensure that therapeutic molecules reach the intended target organ or tissue, such that the effectiveness of the drug is maximized. The efficiency of a drug delivery system greatly depends on the choice of drug carrier. Recently, there has been growing interest in using micro-and nanofibers for this purpose. The reasons for this growing interest include these materials' high surface area to volume ratios, ease of fabrication, high mechanical properties, and desirable drug release profile. Here, we review developments in using these materials made by the most prevalent methods of fiber fabrication: electrospinning, microfluidics, wet spinning, rotary spinning, and self-assembly for drug delivery purposes. Additionally, we discuss the potential to use these fiber based systems in research and clinical applications.
