A barcode magnetic nanowire typically comprises a multilayer magnetic structure in a single body with more than one segment type. Interestingly, due to selective functionalization and novel interactions between the layers, it has attracted significant attention, particularly in bioengineering. However, analyzing the magnetic properties at the individual nanowire level remains challenging. Herein,...
Individual Barcode Nanowires
A wide‐field quantum microscope based on diamond nitrogen‐vacancy centers is used to image the magnetic field from individual barcode magnetic nanowires made of multilayer magnetic structures such as Fe–Au and Fe–Co. The detailed analysis of magnetic images allows for the extraction of crucial magnetic properties of barcode magnetic nanowires such as magnetization and...
Fine control of ultramicroporosity (<7 Å) in carbon molecular sieve (CMS) membranes is highly desirable for challenging gas separation processes. Here, a versatile approach is proposed to fabricate hybrid CMS (HCMS) membranes with unique textural properties as well as tunable ultramicroporosity. The HCMS membranes are formed by pyrolysis of a polymer nanocomposite precursor containing metal‐organic...
Magnetic‐plasmonic nanoparticles have received considerable attention for widespread applications. These nanoparticles (NPs) exhibiting surface‐enhanced Raman scattering (SERS) activities are developed due to their potential in bio‐sensing applicable in non‐destructive and sensitive analysis with target‐specific separation. However, it is challenging to synthesize these NPs that simultaneously exhibit...
In article number 1803563, Yu Jin Kim and co‐workers report a method to control the structure of shell particles composed of PC60 surfactant and PC61BM semiconductor via one‐ and two‐phase methodology in water‐borne core–shell nanoparticles (NPs). The NPs exhibit shell morphology‐dependent photonic particle activity, and they show ultra‐fast charge separation and stable property compared with single...
This article describes p–n heterostructured water‐borne semiconductor naonoparticles (NPs) with unique surface structures via control of shell morphology. The shell particles, comprising PC60–[6,6]‐phenyl‐C61‐butyric acid methyl ester (PC61BM) composite, having n‐type semiconductor characteristics, notably influence the charge carrier behavior in the core–shell NPs. A one‐ or two‐phase methodology...
Recently, polymer‐coated magnetite (Fe3O4) nanoparticles (NPs) are extensively studied for applications in therapeutics or diagnostics using photothermal effect. Therefore, it is essential to understand the interactions between Fe3O4 NPs and polymers when optical stimuli are applied. Herein, the photonic reactions of Fe3O4 NPs and polymer composites upon application of a 780 nm multiphoton laser are...
