Highly efficient and stable electrocatalysts from inexpensive and earth‐abundant elements are emerging materials in the overall water splitting process. Herein, cobalt iron hydroxide nanosheets are directly deposited on nickel foam by a simple and rapid electrodeposition method. The cobalt iron hydroxide (CoFe/NF) nanosheets not only allow good exposure of the highly active surface area but also facilitate...
Various strategies for combination therapy to overcome current limitations in cancer therapy have been actively investigated. Among them, simultaneous delivery of multiple drugs is a subject of high interest due to anticipated synergistic effect, but there have been difficulties in designing and developing effective nanomaterials for this purpose. In this work, dual‐pore coexisting hybrid porous silica...
Interfacing biomolecules with functional materials is a key strategy toward achieving externally‐triggered biological function. The rational integration of functional proteins, such as enzymes, with plasmonic nanostructures that exhibit unique optical properties such as photothermal effect provides a means to externally control the enzyme activity. However, due to the labile nature of enzymes, the...
Targeted and sustained delivery of drugs to diseased tissues/organs, where body fluid exchange and catabolic activity are substantial, is challenging due to the fast cleansing and degradation of the drugs by these harsh environmental factors. Herein, a multifunctional and bioadhesive polycaprolactone‐β‐cyclodextrin (PCL‐CD) polymersome is developed for localized and sustained co‐delivery of hydrophilic...
A modular strategy for the solubilization and protection of hydrophobic transition metal catalysts using the hydrophobic pockets of water soluble gold nanoparticles is reported. Besides preserving original catalyst activity, this encapsulation strategy provides a protective environment for the hydrophobic catalyst and brings reusability. This system provides a versatile platform for the encapsulation...
Precisely engineering the decoration of metal nanoparticles on the special surface of semiconductor represents a promising strategy to design efficient metal–semiconductor heterostructured photocatalysts. This study demonstrates a versatile soft‐template method to fabricate a novel nonsymmetrical heterostructured Ag/AgI nanoplate, in which only one side surface of the nanoplate is covered with uniform...
Exploration of the relationship between electrocatalytic activities and their chemical valence is very important in rational design of high‐efficient electrocatalysts. A series of porous nickel sulfides hybridized with N and S co‐doped carbon nanoparticles (NixSy‐NSCs) with different chemical valences of Ni, Ni9S8‐NSCs, Ni9S8‐NiS1.03‐NSCs, and NiS1.03‐NSCs are successfully fabricated, and their electrocatalytic...
The vesicle is one of the most intriguing platforms for drug delivery, which is believed to improve drug efficacy. In the past few decades, a great deal of materials have been explored to make vesicles, including lipids, block copolymers, dendrons, erythrocyte membranes, and even DNA. Other than shape and size control, most efforts are focused on achieving certain functions, for example, an abundance...
The fundamental challenge in designing transparent pressure sensors is the ideal combination of high optical transparency and high pressure sensitivity. Satisfying these competing demands is commonly achieved by a compromise between the transparency and usage of a patterned dielectric surface, which increases pressure sensitivity, but decreases transparency. Herein, a design strategy for fabricating...
Semiconductor‐based surface enhanced Raman scattering (SERS) has attracted great attention due to its excellent spectral reproducibility, high uniformity, and good anti‐interference ability. However, its relatively low SERS sensitivity still hinders its further developments in both performance and applications. Since the SERS is a peculiar surface effect, investigating the facet‐dependent SERS activity...
A multifunctional interlayer, composed of molybdenum diphosphide (MoP2) nanoparticles and a carbon nanotube (CNT) film, is introduced into a lithium–sulfur (Li–S) battery system to suppress polysulfide migration. Molybdenum diphosphide acts as the catalyst and can capture polysulfides and improve the polysulfide conversion activity during the discharge/charge processes. The CNT film acts as a conductive...
Despite the versatile forms of colloidal aggregates, these spontaneously formed structures are often hard to find a suitable application in nanotechnology and materials science. A determinate reason is the lack of a suitable method to capture the transiently formed and quickly evolving colloidal structures in solution. To address this challenge, a simple but highly efficient strategy is herein reported...
While nanoparticles are an increasingly popular choice for labeling and tracking stem cells in biomedical applications such as cell therapy, their intracellular fate and subsequent effect on stem cell differentiation remain elusive. To establish an effective stem cell labeling strategy, the intracellular nanocrystal concentration should be minimized to avoid adverse effects, without compromising the...
Herein, the hydrothermal synthesis of porous ultrathin ternary NiFeV layer double hydroxides (LDHs) nanosheets grown on Nickel foam (NF) substrate as a highly efficient electrode toward overall water splitting in alkaline media is reported. The lateral size of the nanosheets is about a few hundreds of nanometers with the thickness of ≈10 nm. Among all molar ratios investigated, the Ni0.75Fe0.125V0.125...
Large‐scale 2D single‐crystalline copper nanoplates (Cu NPLs) are synthesized by a simple hydrothermal method. The combination of a mild reductant, stabilizer, and shape modifier allows the dimensional control of the Cu nanocrystals from 1D nanowires (NWs) to 2D nanoplates. High‐resolution transmission electron microscopy (HR‐TEM) reveals that the prepared Cu NPLs have a single‐crystalline structure...
An efficient treatment for osteoarthritis (OA) can benefit from the local release of a high therapeutic dose over an extended period of time. Such a treatment will minimize systemic side effects and avoid the inconvenience of frequent injections. To this aim, nanocrystal–polymer particles (NPPs) are developed by combining the advantages of nanotechnology and microparticles. Nanocrystals are produced...
In article number 1703386, Periklis Pantazis and co‐workers use Second Harmonic Generating (SHG) nanoprobes to label, with high contrast, clinically relevant hematopoietic stem cells (HSCs) by establishing an effective cell labeling procedure without affecting the HSC differentiation potential. Quantitative single‐cell analysis reveals that freshly isolated HSCs show limited nanoparticle uptake, whereas...
In article number 1703862, Sung Chul Yi and co‐workers demonstrate the significance of blending in diverse anions for the development of complex, high‐performing, and stable electrodes for hydrogen evolution.
