The low separation efficiency of photoinduced carriers in BiPO4 system limited its photocatalytic application. Here, lotus flower-like heterostructure Ti3C2/BiPO4 was constructed via a simple hydrothermal synthesis without surface active agent. Schottky barrier between BiPiO4 and Ti3C2 interface could be formed due to the large gap work function for two components, which efficiently promoted photoproduced holes extraction, photogenerated electron-hole pairs further inhibited photo-corrosion...

The indication of information in materials is widely used our daily life, and optical encoding are ideal for loading due to their easily readable nature adjustable properties. However, most them could only indicate one type information, either changing or unchanging the mutual interference. Inspired by firefly, we present a non-interfering bipolar system capable indicating both information. A photochemical afterglow material incorporated into photonic crystal matrix through high-throughput...

The self-assembly of hexagonal cylinder-forming diblock copolymers under laterally triangular confinement provides a useful method for the fabrication defect-free patterns. However, as size becomes larger, its effect drops down and thus occurrence defects is still inevitable. Here, we first use self-consistent field theory (SCFT) to demonstrate that there always exists thermodynamically stable perfect pattern within triangle any by comparing free energy morphology with many defective...

We investigated the co-assembly of nanoparticles P and amphiphilic diblock copolymers AB in selective solvents using a dissipative particle dynamics (DPD) method. By controlling nanoparticle concentration interaction parameter between hydrophobic blocks solvents, we found that aggregation morphology can be changed from rod-like micelles to disk-like further vesicles. The ratio hydrophobic/hydrophilic block largely affects structural characteristics vesicles dispersion nanoparticles....

Both experimental and theoretical studies have shown that a cylinder-forming block copolymer melt under the confinement of nanopore can self-assemble into an interesting sequence ordered nanostructures in terms pore size, including single cylinder, stacked disks, helix, double-helix, so on. However, most these focused on normal cylinder phase formed by simple AB diblock at low volume fraction (e.g., fA A-block). Whether this is universal or specifically depends architecture question to be...

Cyclic brush (cb) copolymers that are composed of a cyclic core densely grafted with radiating polymer brushes have emerged recently as innovative materials for both fundamental and practical investigations due to the unique topology-generated properties. The self-assembled microstructures amphiphilic cb block in solutions investigated by dissipative particle dynamic simulation. A series structures, such rods, plates, vesicles, large compound bilayers, spheres, obtained from at various...

On basis model, find that well manipulated just...

Bacterial vaccines have been widely used to prevent infectious diseases, especially in veterinary medicine. Although there are many reports on bacterin adjuvants, only a few contain innovations adjuvants. Taking this into consideration, study we designed and synthesized new aluminum (oxy) hydroxide (AlOOH) nanorod (Al-NR) with diameter of 200 ± 80 nm length 1.1 0.6 μm.

The kinetic evolution of ordered phases, i.e., single-cylinder (C1), stacked disks (Dk), and single-helix (H1), formed by a cylinder-forming AB diblock copolymer melt under the confinement nanopores is investigated using self-consistent field theory (SCFT) in conjunction with string method. For C1 → H1, nucleation piece H1 rate-determining step, so heterogeneous process preferred. Dk transition confined small nanopore, phase tends to break sequentially, forming one one. first barrier for...
