Nanocrystals provide a variety of size and shape‐dependent properties with applications in wide range areas, gaining much attention the past few years. However, due to nature kinetic nanocrystal growth, procedures often require strict experimental conditions shape nanocrystals are difficult control. In such context, organic templates, which artificially modified or synthesized, can direct inorganic nucleation growth achieve desired shape, ultimately properties. this review article, two...

Two-dimensional (2D) materials, especially the inorganic 2D nanosheets (NSs), are of particular interest due to their unique structural and electronic properties, which favorable for photoelectronic applications such as photocatalysis. Here, we design fabricate ultrathin ZnO NSs decorated with Au nanoparticles (AuNPs), though molecular modelling hydrothermal growth followed by surface modification used an effective photocatalyst photocatalytic organic dye degradation hydrogen production.

An unconventional but facile approach to prepare size-tunable core/shell ferroelectric/polymeric nanoparticles with uniform distribution is achieved by metal-free atom transfer radical polymerization (ATRP) driven visible light under ambient temperature based on novel hyperbranched aromatic polyamides (HBPA) as a functional matrix. Cubic BaTiO3/HBPA nanocomposites can be prepared in-situ polycondensation process precursors (barium hydroxide (Ba(OH)2) and titanium(IV) tetraisopropoxide...

B4C/TiB2 ceramic composites reinforced with three size scales (average particle size: 7 μm, 500 nm, and 50 nm) of TiB2 were prepared by using a pressureless sintering furnace at 2100 °C under Ar atmosphere for 60 min. The results demonstrated that during the process, located on boundaries between different B4C grains could inhibit grain growth which improved mass transport mechanism driving force. A semi-coherent interface SiC was found, is supposed to help reduce energy obtain good...

In the course of routine bridge maintenance, edge detection allows partial condition to be viewed. However, many methods often have unsatisfactory performances when dealing with images complex backgrounds. Moreover, processing involves manual selection thresholds, which can result in repeated testing and comparisons. To addresses these problems this paper, wavelet transform modulus maxima method is used detect target image, then threshold value image determined automatically according OTSU...
