Abstract:

My 5th Paper

My 5th paper has been accepted for publication in Macromolecular Research. This paper discuss about development of new polylactide-based material by combining stereocomplexation and nanocomposites. After published, I will share this paper.

My 4th Paper

My 4th paper has been accepted for publication in Polymer International. This paper discuss about effective processing of stereocomplex polylactide formation. After published, I will share this paper.

Alhamdulillah Panen

Setelah lama menunggu keputusan proses pengajuan manuscript ke beberapa jurnal internasional sejak akhir 2010. Akhirnya membuahkan hasil juga. Dalam periode Oktober – November, total 3 paper (Alhamdulillah dengan status first author semua) diterima semua.
Pada tanggal 8 Oktober 2011, Aku mendapatkan email dari Editor Macromolecular Research yang menyatakan bahwa:
Dear Purba,

My 1st US Patent

Alhamdulillah.

Lagi iseng-iseng search patent tentang supercritical fluid, tak disangka muncul nama sendiri. Alhamdulillah. Akhirnya keluar juga di US Patent. Ini adalah pertama kali melihat nama sendiri di US Patent. Semoga akan terus memproduksi patent-patent berikutnya. Amiin.
Untuk patent pertama di US Patent berjudul:
“METHOD FOR PREPARING BIODEGRADABLE POLYMER STEREOCOMPLEXES USING A SUPERCRITICAL FLUID-ORGANIC SOLVENT SYSTEM AND STEREOCOMPLEXES PREPARED BY THE SAME” (United States Patent Application 20110201710 Kind Code: A1).

2nd Korean Patent

Alhamdulillah Tahun 2011 ini bisa juga mengajukan patent kedua ke Korean Patent dengan judul: “초임계 유체-유기용매 시스템을 이용한 점토/고분자 복합체 제조 방법”. (A Preparation Method of Clay/Polymer Composite using Supercritical Fluid-Organic Solvent System). Korean Patent: KP Appl. 2011-0044812 (2011,05,12) Mohon do’anya semoga tetap bisa produktif dimasa mendatang. Amiin.

2nd Paper

1st Korean Patent

Alhamdulillahirobbil alamiin Dalam 1 tahun pertama bisa mengajukan korean patent dengan judul: “초임계 유체-유기용매 시스템을 이용한 생분해성 고분자 입체이 성질 복합체의 제조 방법 및 그로부터 제조된 고분자 입체이성질 복합체” (Stereocomplex formation of biodegeradable polymers in supercritical fluid-solvent system). KP Appl. 10-2010-0013353 (2010,02,12). Semoga menjadi awal untuk keluarnya patent-patent berikutnya baik Korean Patent ataupun US Patent. [...]
