Metal‐oxo clusters have emerged as advanced proton conductors with well‐defined and tunable structures. Nevertheless, the exploitation of metal‐oxo clusters with high and stable proton conductivity over a relatively wide temperature range still remains a great challenge. Herein, three sulfate groups decorated zirconium‐oxo clusters (Zr6, Zr18, and Zr70) as proton conductors are reported, which exhibit...
This work reports the design of a wavelength sensor composed of two identical perovskite (FA0.85Cs0.15PbI3) photodetectors (PDs) that are capable of discriminating incident wavelength in a quantitative way. Due to strong wavelength‐dependent absorption coefficient, the penetration depth of the photons in the FA0.85Cs0.15PbI3 nanofilms increases with the increasing wavelength, leading to a gradual...
To develop durable and low‐price catalysts of methanol oxidation to commercialize direct methanol fuel cell, many attempts have been made at fabricating Pt‐based hybrids by designing component‐, morphology‐, facet‐, integration‐pattern‐varied nanostructures, and have achieved considerable successes. However, most of present catalysts still lack robust catalytic durability especially owing to the corrosion...
In this study, a highly sensitive and self‐driven near‐infrared (NIR) light photodetector based on PdSe2/pyramid Si heterojunction arrays, which are fabricated through simple selenization of predeposited Pd nanofilm on black Si, is demonstrated. The as‐fabricated hybrid device exhibits excellent photoresponse performance in terms of a large on/off ratio of 1.6 × 105, a responsivity of 456 mA W−1,...
A noble‐metal‐free electrocatalyst is fabricated via in situ formation of nanocomposite of nitrogen‐doped graphene quantum dots (NGQDs) and Ni3S2 nanosheets on the Ni foam (Ni3S2‐NGQDs/NF). The resultant Ni3S2‐NGQDs/NF can serve as an active, binder‐free, and self‐supported catalytic electrode for direct water splitting, which delivers a current density of 10 mA cm−2 at an overpotential of 216 mV...
On page 3344, X.‐Z. Zhang and co‐workers present how versatile bioactive peptides could be constructed to possess multiple capabilities. Mesoporous silica nanoparticles modified with peptides could realize many types of functionalities, including site‐specific targeting, fluorescence imaging, and intracellular diagnosis, especially the controlled release of a drug or gene for tumor treatment.
During the last decade, using versatile, promising, and fascinating mesoporous silica nanoparticles (MSNs) as site‐specific and stimuli‐responsive drug delivery systems (DDSs) has received concentrated research interest. As one of the most attractive surface modification units, peptides have inherent bioactivity, biodegradability and biocompatibility. Recent progresses in the utilization of versatile...
