We demonstrated potential features of gold nanoparticle bipyramid (AuNB) for an electrochemical biosensor. The facile synthesis method and controllable shape size the AuNB are achieved through optimization cetyltrimethylammonium chloride (CTAC) surfactant over citric acid (CA) ratio determining control typically spherical Au seed its transition into a penta-twinned crystal structure. observe that optimized CTAC CA facilitates flocculation in which seeds with as tiny ∼14.8 nm could be...
In this study, we reported the construction of Gold Nanospike (AuNS) structures on surface screen-printed carbon electrode (SPCE) used for non-enzymatic electrochemical detection. This modification was prepared with a one-step electrodeposition method by controlling parameters, such as applied potential and deposition time, via Constant Potential Amperometry (CPA). Those parameters precursor solution concentration were varied to investigate optimum configuration. The results confirmed that...
Generally, a maintenance process of machine tool is oriented to maintain its reliability and availability in relation productivity. This productivity will make direct impact on the economic aspect plant. Ecomaintenance concept which sees different perspective. There another effect that maintained well environmental beside benefit technology aspects. If with proper maintenance, it have performance suitable age design condition. A good generally has minimum rate pollutant waste possible...
Turbines convert the kinetic energy of ocean currents into electrical produced by sea current electric power plant. This study aims to design a generator turbine modeling that is carried out using Computational Fluid Dynamic (CFD) approach comparing geometric performance based on angle attack and Tip Speed Ratio (TSR) value Savonius-Darrieus Turbine. Having done several trials errors during collecting data, TSR 1.427; 2.853; 4.28; 5; 5.7 proposed. Here, NACA 0018 series has been adopted The...
Pipa baja merupakan salah satu produk turunan dari yang dikategorikansebagai industri hilir banyak digunakan baik untuk aplikasi strukturalmaupun media pengaliran. Permasalahan sering terjadi pada mesinperata (flattening) pelat tersebut adalah tidak ratanya (unflat) saatproses pembuatan pipa baja. Kerataan sangatlah penting karenaberpengaruh terhadap pembentukan profile pipa. Mesin perata (flattening)pelat komponen mesin dalam pembuatanpipa berfungsi meratakan (flat) lembaran Rollingadalah...
Measurement of torque and performance traction wheel is generally employed a device big soil bin. The however not to be as leaming media in the classroom scale. Development model bin measure tourque wheel, wich can used classroom, necessary, order gain effective simplicity for learning systtem. designed by decreasing dimension smaller, whereas main component shape are remaining same,and development needed, i.e.: 1) type contact surface made sandy loam soil, rubber, iron plate, 2) dynamic...
