Data from trials investigating the effects and risks of endovascular thrombectomy for treatment stroke due to basilar-artery occlusion are limited.
The structural dynamics of the solid-liquid interfaces (SLEIs) determines chemistry in all electrochemical processes. Here, by combining multiple operando synchrotron spectroscopies, we identify at atomic level a general evolution single-atom Ni SLEIs into near-free atom state oxygen reduction reaction (ORR). We uncover that tends to be dynamically released from nitrogen-carbon substrate and then forms near-free, isolated-zigzag active site (Ni1(2-δ)+N2) during reaction. This Ni1(2-δ)+N2...
Birefringent materials are of great importance in optical communication and the laser industry, as they can modulate polarization light. Limited by their transparency range, few birefringent materials, except α-BaB2O4 (α-BBO), be practically used deep ultraviolet (UV) region. However, α-BBO suffers from a phase transition does not have enough UV By introducing relatively small alkali metal Na+ cation F– anion to keep favorable structural features α-BBO, we report new crystal Na3Ba2(B3O6)2F...
Water-soluble fluorescent copper, silver and gold nanoclusters with quantum yields of 2.2, 6.8 5.3%, respectively, are prepared by a robust photoreduction their inorganic precursors in the presence poly (methacrylic acid) functionalized pentaerythritol tetrakis 3-mercaptopropionate.
Photodynamic therapy (PDT) and photothermal (PTT) are two kinds of treatment for tumors. Herein, a new aggregation-induced emission (AIE)gen (MeO-TPE-indo, MTi) is synthesized with D-π-A conjugated structure. MTi, which has an electron donor acceptor on tetraphenylethene (TPE) skeleton, can induce the effective generation reactive oxygen species (ROS) PDT. With guide indolium group, MTi target image mitochondrion selectively. In order to get good dispersion in water long-time retention...
Iron-based artificial enzyme nanomimics show promise for biocatalytic tumor therapy.
Nitrogen-doped graphene quantum dots (N-GQDs) are synthesized at low temperature as a new catalyst allowing electrochemical detection of 2,4,6-trinitrotoluene (TNT). N-GQDs made by an oxidative ultrasonication oxide (GO) forming nanometer-sized species, which then chemically reduced and nitrogen doped reacting with hydrazine. The as-synthesized have average diameter ∼2.5 nm N/C atomic ratio up to ∼6.4%. To detect TNT, TNT is first accumulated on modified glassy carbon (N-GQDs/GC) electrode...
A promising trend in plasmonics involves shrinking the size of plasmon-supporting structures down to a few nanometers, thus enabling control over light–matter interaction at extreme-subwavelength scales. In this limit, quantum mechanical effects, such as nonlocal screening and quantization, strongly affect plasmonic response, rendering it substantially different from classical predictions. For very small clusters molecules, collective modes are hard distinguish other excitations...
Bacterial/fungal biofilm-mediated persistent endodontic infections (PEIs) are one of the most frequent clinical lesions in oral cavity, resulting apical periodontitis and tooth damage caused by loss minerals. The conventional root canal disinfectants poorly bio-safe harmful to teeth tissues, making them ineffective treating PEIs. development nanomaterials is emerging as a promising strategy eradicate disease-related bacteria/fungi. Herein, glucose oxidase (GOx)-modified magnetic...
Abstract Graphene quantum dot (GQD) encapsulated melamine‐formaldehyde (MF) polymer microspheres with uniform particle size and tunable high‐quality white‐light emissions are prepared via a polymer‐mediated GQD assembly encapsulation strategy. In solution, GQDs first aggregated MF prepolymer through electrostatic interaction further inside the formed by polymerization of under acid catalysis heating. During this process, fixed in matrix their emission extended from blue to full visible...

A series of solid supramolecules based on acrylamide-phenylpyridium copolymers with various substituent groups (P-R: R=-CN, -CO2 Et, -Me, -CF3 ) and cucurbit[7]uril (CB[7]) are constructed to exhibit tunable second-level (from 0.9 s 2.2 s) room-temperature phosphorescence (RTP) in the amorphous state. Compared other P-R/CB[7] (R=-CN, -Me), P-CF3 /CB[7] displays longest lifetime (2.2 s), which is probably attributed fluorophilic interaction cucurbiturils leading a uncommon host-guest between...
Enterococcus faecalis (E. faecalis) biofilm-associated persistent endodontic infections (PEIs) are one of the most common tooth lesions, causing chronic periapical periodontitis, root resorption, and even loss. Clinical canal disinfectants have risk damaging soft tissues (e.g., mucosa tongue) teeth in oral cavity, unsatisfactory to therapy PEIs. Nanomaterials with remarkable antibacterial properties good biocompatibility been developed as a promising strategy for removing pathogenic bacteria...
Heavy metals (HMs) in aquatic environments are characterized by high toxicity, a propensity for bioaccumulation, and non-degradability, pose significant risks to biological communities. Previous studies of HMs lakes have shown that the physical chemical characteristics lake water may control both migration sediments concentration heavy water. In fact, change changes metal fraction sediment, which controls release HMs. this paper, we investigated effects pH, temperature, salinity levels...
Pure water splitting by charged semiconductors and solar photons to concurrently generate H2 O2 molecules has gained notable attention due worldwide clean energy generation storage. Despite significant advancements, challenges facing severe carrier recombination sluggish electron transport continue hinder the intrinsic efficiency of splitting. Here, we fabricate two-dimensional graphitic carbon nitride-hybridized sulfur thionic polymorphs (CN/S100/S010 junctions) incorporating photoactive...

The effects of size and europium concentration on photoluminescence properties La2O2S: Eu3+ nanocrystals (∼20 nm) the corresponding bulk were studied. results indicate that in nanocrystals, absorption edge largely shifted to blue comparison bulk, which was mainly attributed variation phonon-excitation relaxation. Two excitation bands observed, located at ∼250 ∼330 nm, respectively, charge transfer (CT) transitions Eu−O Eu−S. Relative CT transition Eu−O, Eu−S increased greatly with...
Pt nanoparticles (NPs) have been reported to demonstrate four kinds of enzyme-like activity including superoxide dismutase (SOD), catalase, oxidase and peroxidase. Some these activities interfere with each other. For instance, as antioxidant enzyme mimics, their SOD catalase are very helpful in scavenging related reactive oxygen species (ROSs). However, oxidase-like and/or peroxidase-like may simultaneously oxidize some natural antioxidants, thus compromising the final anti-oxidation...
Direct water splitting in pure relying on photocatalysis is an effective way to realize efficient solar chemical fuel conversion toward solving the global energy crisis and environmental problems. Here, via a "high-valence metal single-atom confinement" strategy, we effectively modify valence band structure of semiconductor photocatalyst spontaneous photocatalytic water. This as-prepared PtII–C3N4 could achieve activity with H2 production rate up ∼140 μmol g–1 h–1, about 10 times that Pt...
