TiO2 (titania) is one of materials science's most extensively researched compounds. Due to a number of unique properties, it is used, for instance, in photocatalysis, dye-sensitized solar cells, and biomedical devices. Titanium dioxide nanotubes (TNTs), also known as TiO2 NTs, have attracted a lot of attention in recent years. The current study examines the anodization-based production of nanospheres and its effects on potential variation. Structural studies are characterised using energy dispersive X-ray spectroscopy (EDAX) and field emission scanning electron microscopy (FESEM). A UV-VIS spectrophotometer was used to examine the band gap of the samples anodized at four different voltages ranging from 12 to 40 V. The sample anodized at 12 V shows nanospheres clearly and it holds the lowest band gap.
二氧化钛(二氧化钛)是材料科学中研究最广泛的化合物之一。由于许多独特的性质，它被用于，例如光催化，染料敏化太阳能电池和生物医学设备。二氧化钛纳米管(Titanium dioxide nanotubes, TNTs)也被称为TiO2纳米管，近年来引起了人们的广泛关注。目前的研究考察了基于阳极氧化的纳米球生产及其对电位变化的影响。结构研究使用能量色散x射线光谱(EDAX)和场发射扫描电子显微镜(FESEM)进行表征。用紫外-可见分光光度计测定了样品在12 ~ 40 V 4种不同电压下阳极氧化后的带隙。在12v下阳极处理的样品显示出清晰的纳米球，并且具有最小的带隙。

The results of computer simulation of the process of macrocrack growth in an elastomeric nanocomposite and its interaction with strands that can occur between adjacent closely spaced filler particles during material tension are presented. The hypothesis that under uniaxial tension the elastomer is able to withstand significantly greater loads compared to other types of stress state (at the same intensity of deformation) was used in the simulation. A strength criterion depended on characteristics of the stress-strain state of elastomer (maximum strength is achieved with uniaxial tension) was developed to take this effect into account. Numerical studies showed that with a fairly close approach of the macrocrack front to the gap between filler particles, the formation of a reinforced strand is possible there, connecting the “shores” of the macrocrack and, accordingly, preventing its further progress. It is well known that the addition of a rigid filler to the elastomer allows the resulting composite to withstand a significantly higher external load compared to unfilled material. This is due to the fact that in a material without filler, nothing prevents the growth of macrocrack. But in an elastomeric composite, the microstrands that occur between the filler particles can delay its spread.

The current investigation deals with the assessment of stability and physicochemical properties of copper oxide (CuO) nanoparticles dispersed Azadirachta indica oil-biodiesel blend (B20). CuO nanoparticles were prepared at 75 ppm and dispersants were added at the same ratio as CuO nanoparticles. TRITONX, QPAN80 and TWEEN 80 were used as dispersants. An ultrasonic bath sonicator was used to sonicate the nanoparticles and later the ultrasonic sonicator was used to prepare the nanofuel. Also, the UV photo spectrometer was used for stability analysis in terms of absorption and transmission. The stability analysis was carried out for the duration of three weeks. The stability of CuO nanoparticles was increased in B20 when the dispersants were added compared to the base nanoparticles. However, higher absorption and lower permeability were observed in the QPAN-added nanofuels than in the other samples. In addition, the stability of all the nanofuel samples slightly decreased at the end of week 3. The higher absorbance and lower transmittance of B20+CuO75+Tw75 were 4.08 and 86.09% in week 1, 4.06 and 88.03% in week 2, and 4.04 and 92.03% in week 3, respectively. Moreover, the physicochemical properties such as cetane number and heating value of nanoparticle-added B20 is improved.
