Improving the detection limit of surface-enhanced Raman scattering (SERS) is a significant issue for design and application plasmon substrate. It always suffers from weak affinity probe molecules on nanoscale surface, uncontrollable aggregation behaviors nanoparticles, strong fluorescence detected substance. In this paper, AgNPs/SiO2 substrate prepared by rapid thermal annealing method with mea...

Polydimethylsiloxane (PDMS) is a biocompatible polymer that exhibits high flexibility and heat resistance. PDMS can be rapidly cross-linked at low temperatures by platinum-catalyzed addition reaction used to create nanostructures owing its formability. In this study, free-standing thin films (PDMS nanosheets) were fabricated characterized. nanosheets, about 90–2500 nm thick, prepared using micr...

Laser powder bed fusion is an efficient technique for additive manufacturing of metallic materials. The quality the material produced depends on optimization a large range build parameters and complex thermo-mechanical process prone to inducing detrimental features such as porosity residual stresses negatively affecting fatigue resistance lifetime. Here we apply neutron Bragg edge radiography i...

We present a computational study of free surface flows with rheologically complex interfaces in the film formation region slot coater. The equations motion for incompressible Newtonian liquids bulk flow are coupled Boussinesq–Scriven constitutive equation viscous dynamic boundary condition at liquid-air and solved mixed finite element method. show that interfacial viscosity plays major role dyn...

The purpose of this work was to develop a practical scale-up model for a solvent-based pan-coating process. scale up of adsorption column Practical scale-up rules to determine. ABSTRACT: Although significant progress had been made in developing general scale-up rules for an aqueous pan-coating process, there. Practical scale-up rules to determine the key parameters pan load, pan speed, spray ra...

Abstract The effect of coating parameters NMC622 cathodes and graphite anodes on their physical structure half-cell electrochemical performance is evaluated by design experiments. Coating include the coater comma bar gap, ratio web speed. properties studied are gravimetric volumetric capacity, rate performance, areal specific impedance (ASI) C-rate. Differences in manufacturing effects electrod...

Beras sebagai pangan utama masyarakat Indonesia yang merupakan unsur esensial kehidupan,tetapi memiliki indeks glikemik tinggi. Salah satu tumbuhan endemik dapatdijadikan alternatif pengganti beras adalah porang. Hal ini disebabkan karena porang mengandungglukomanan. Pengolahan di beragam salah satunya dibuat menjadi nasi uduk.Kombinasi tepung dan kelapa dapat dijadikan inovasi dalam pembuatann...

Abstract Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA) was chosen as a hole transport layer for inverted perovskite solar cells (PSCs). It is the first deposited on FTO substrate and thus directly affect structure performance of PSCs. found that untreated PTAA surfaces yielded large distribution photovoltaic parameters low reproducibility. In this work, powder dissolved in chlorobenzen...
