The aim of this study is to the influence different solvents on structure and electrical properties graphene oxide. GO was obtained from graphite flakes by using modified hummers method in which conventional hummer's method. In method, experiment synthesized without sodium nitrate (NaNO3) ice bath, but carried out at room temperature. Prepared powders were then dissolved into solvents, namely acetone ethanol. Then spin-coated onto silicon wafer IDE produce acetone-GO (A-GO) ethanol-GO...

Facebook's corpus of photos, videos, and other Binary Large OBjects (BLOBs) that need to be reliably stored quickly accessible is massive continues grow. As the footprint BLOBs increases, storing them in our traditional storage system, Haystack, becoming increasingly inefficient. To increase efficiency, measured effective-replication-factor BLOBs, we examine underlying access patterns identify temperature zones include hot are accessed frequently warm far less often. Our overall BLOB system...

Cumulative research on resistomes and microbiomes from aquatic environments has revealed that both integrated freshwater monoculture aquaculture systems can cause the development dissemination of antibiotic resistance genes (ARGs) associated mobile genetic elements (MGEs). However, few studies have examined differences in between different modes, those do focused residues or individual genes. In current study, we collected 44 environmental samples two farms four (two duck fish farms, laying...

Abstract Tuberculosis (TB), caused by Mycobacterium tuberculosis ( M. ), requires a high level of attention and is one the most infectious diseases in air. Present methods diagnosing TB remain ineffective owing to their low sensitivity time consumption. In this study, we produced green graphene nanofiber laser biosensor (LSG-NF) decorated with oil palm lignin-based synthetic silver nanoparticles (AgNPs). The resulting composite morphology was observed field-emission scanning electron...
