Quantitative surface enhanced Raman spectroscopy (SERS) requires precise control of enhancement factor and detection uniformity across the SERS substrate. Here, we show that alkanethiolate ligand-regulated silver (Ag) nanoparticle films can be used to achieve quantitative measurements down single-molecule level. The two-dimensional hexagonal close-packed superlattices Ag nanoparticles formed in these allow for over a large area with excellent high factor. In particular, signal from thiolate...
In comparison to noble metals (gold and silver), aluminum is a sustainable widely applicable plasmonic material owing its abundance in the Earth's crust compatibility with complementary metal–oxide–semiconductor (CMOS) technology for integrated devices. Aluminum (Al) has superior performance ultraviolet (UV) regime lowest loss good full visible regime. Furthermore, films can remain very stable ambient environment due formation of surface native oxide (alumina) acting as passivation layer....
Plasmonic nanoantenna arrays hold great promise for diffraction-unlimited light localization, confinement, and transport. Here, we report on linear plasmonic composed of colloidal gold nanocubes precisely assembled using a nanomanipulation technique. In particular, show the direct evidence dark propagating modes in plasmon coupling regime, allowing transport guided waves without far-field radiation losses. Additionally, demonstrate possibility dispersion engineering coupled nanocube chains....
Abstract Plasmonic logic gates provide a promising platform to realize diffraction‐unlimited all‐optical circuits. However, previous plasmonic suffer from narrow bandwidth and high loss. Here, broadband are proposed demonstrated using unique design based on curved silver gratings. These can maintain intensity contrast ratio (29 dB) under front optical illumination. And, the feature is achieved due of zero path difference different positions grating output port. All seven fundamental...
Significance Defects in two-dimensional (2D) transition-metal dichalcogenides play a crucial role controlling the spatiotemporal dynamics of photogenerated charge carriers, which remain poorly understood to date. In this paper, defect-mediated carrier diffusion and recombination WS 2 monolayers are quantitatively investigated by laser-illuminated microwave impedance microscopy. Surprisingly, photoresponse is general stronger more disordered regions samples. Such counterintuitive observations...
Based on the engineering of TiN capping layer, tailoring crystalline phases and paraelectric(PE)/antiferroelectric(AFE)/ferroelectric(FE) properties nanoscale ZrO2 thin films are demonstrated without any post-annealing treatment. The by layer leads to conversion from PE AFE electrical characteristics, while removal results in AFE-to-FE phase transformation ZrO2. nano-beam electron diffraction, high-resolution transmission microscopy X-ray diffraction characterizations identify presence...
The development of efficient and durable electrocatalysts for oxygen reduction reaction (ORR) holds a pivotal significance in the successful commercialization proton exchange membrane fuel cells (PEMFCs) but is still challenging. Herein, we report worm-liked PtCu nanocrystals dispersed on nitrogen-doped carbon hollow microspheres (Pt0.38Cu0.62/N-HCS). Benefiting from its structural compositional advantages, resulting Pt0.38Cu0.62/N-HCS catalyst delivers exceptional electrocatalytic activity...
Guanidine disinfectants are cationic polymers recognized for their effective sterilization properties and ability to prevent bacterial resistance. As a result, they widely utilized in medical, healthcare, household, animal husbandry settings. However, the bactericidal effects mechanisms of guanidine marine aquaculture systems remain unclear due polymeric nature ions complexity environments. The inhibitory polyhexamethylene biguanide (PHMB) on key pathogens probiotics examined this study. It...
Controllable intramolecular spin-polarized flow refers to the manipulation of electron transport within molecules through externally applied stimuli, thereby modulating their spin characteristics and magnetic properties. In this work, we designed synthesized four paramagnetic molecules, PDTN-NN, PDTN-IN, PO-NN, PO-IN, by introducing nitronyl nitroxide (NN) iminonitroxide (IN) radicals into phenothiazine phenoxazine frameworks. Remarkably, successfully generated corresponding...
