Ice-templated self-assembly is used for the integration of 2D graphene sheets into hierarchically porous nanoscroll networks.
Plasmonic systems based on metal nanoparticles a film have generated great interest for surface-enhanced Raman spectroscopy (SERS) chemical sensors. In this study, we describe the fabrication of ultrasensitive SERS substrates high-density gold nanostar assemblies silver films with tailored surface plasmons, where multiple field enhancements from particle-film and interparticle plasmon couplings lightening rod effects sharp tips nanostars contribute to enormous enhancements. We show that...
Integration of surface-enhanced Raman scattering (SERS) sensors onto transparent and flexible substrates enables lightweight deformable SERS which can be wrapped or swabbed on various nonplanar surfaces for the efficient collection detection analytes surfaces. However, development with high sensitivity is still challenging. Here, we demonstrate a substrate based polydimethylsiloxane (PDMS) film embedded gold nanostar (GNS) assemblies. The enable conformal coverage arbitrary surfaces, optical...
Plasmonic systems based on particle-film plasmonic couplings have recently attracted great attention because of the significantly enhanced electric field at gaps. Here, we introduce a hybrid architecture utilizing combined effects gap plasmons and silver film over nanosphere (AgFON) substrates. When gold nanoparticles (AuNPs) are assembled AgFON substrates with controllable distances, AuNP-AgFON system supports multiple from interparticle, particle-film, crevice gaps, resulting in huge...
When semiconducting nanostructures are combined with noble metals, the surface plasmons of in addition to charge transfer interactions between semiconductors and can be utilized provide strong plasmon effects. Here, we suggest a particle-film plasmonic system conjunction tapered ZnO nanowire arrays for ultrasensitive SERS chemical sensors. In this design, gap metal nanoparticles films significantly improved surface-enhanced Raman spectroscopy (SERS) effects compared those interparticle...
We developed a fully automated portable 2-dimensional (2-D) gas chromatography (GC x GC) device, which had dimension of 60 cm × 50 10 and weight less than 5 kg. The device incorporated micropreconcentrator/injector, commercial columns, micro-Deans switches, microthermal injectors, microphotoionization detectors, data acquisition cards, power supplies, as well computer control user interface. It employed multiple channels (4 channels) in the second (2D) to increase 2D separation time (up 32...
This study investigated the effects of pulsed electric field (PEF) treatment on peeling efficiency and textural properties whiteleg shrimp (Litopenaeus vannamei). Shrimp samples were treated at strengths 0, 1.0, 1.5, 2.0 kV/cm to assess PEF impact force, incomplete percentage, texture profile. The results showed that significantly reduced force from 50.88 N in controls 42.99 kV/cm, while percentage incompletely peeled decreased 27.5% 15.9%. Texture profile analysis indicated had no key...
<p>This paper compares Garuda Indonesia and Lion Air, two leading Indonesian airlines, focusing on their operational, financial, strategic differences. Garuda, a state-owned full-service airline, targets business international travelers with focus premium services safety, while low-cost carrier (LCC), caters to budget-conscious passengers through affordability extensive domestic coverage. The study highlights Indonesia’s reliance air travel due its archipelagic geography explores how...
Low-dielectric polymer materials are becoming essential for 5 G mobile communication to achieve mass transport information without signal loss. Herein, we present an aliphatic–aromatic copolyimide using Priamine 1075 (aliphatic) and m-tolidine (aromatic) as diamines. The branched bulky aliphatic units enlarge the free volume, effectively reducing dipole moment density, while aromatic diamine was introduced prevent chain relaxation under operating conditions. We observed that there is optimal...
Three types of the stilbazole derivative, 4-(4-alkoxybenzoyloxy)-4′-stilbazole (nSz), 4-(3,4-dialkoxybenzoyloxy)-4′-stilbazole (nDSz), and 4-(3,4,5-trialkoxybenzoyloxy)-4′-stilbazole (nTSz), were synthesised complexed via hydrogen bonding with phloroglucinol (PG) to build liquid crystals, their mesomorphic properties investigated. In PG/nSz complexes, a wider range was observed than in nSz. The mesophases nematic (n = 6, 8) smectic phases 10, 12). PG/nDSz PG/nTSz complexes showed which not...

Particle-on-film plasmonic systems provide interesting properties, which can be easily tuned by controlling the particle–film gaps.
A microliter-scale solution process was used to fabricate large-area, uniform films of silver nanowires (AgNWs). These thin with cross-AgNWs were deposited onto Au substrates by dragging the meniscus a microliter drop coating trapped between two plates. The hot spot density tuned controlling simple experimental parameters, which changed optical properties resulting films. cross-AgNW on surface served as excellent for surface-enhanced Raman spectroscopy, substantial electromagnetic field...
The silver migration effect into the metastable phase forms a micro-electric path, to enhance relative dielectric permittivity of CaCu3Ti4O12 ceramics for electronic devices. Controlling sintering time uniquely develops as-sintered ceramics. A post-heating process that applies increases permittivity.
