Pengaruh Peak Ground Acceleration (PGA) Terhadap Stabilitas Lereng Kapur

Syntax Literate ; Jurnal Ilmiah Indonesia
Bali Selatan dikenal sebagai salah satu destinasi wisata internasional yang ditandai oleh hamparan pantai dan tebing-tebing kapur yang menjulang. Pada beberapa lokasi, tebing tersebut telah digali atau dimodifikasi untuk meningkatkan aksesibilitas dan menonjolkan daya tarik lanskap, namun aspek stabilitasnya masih sering terabaikan, terutama karena ...

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

Advanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

Advanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...
