Thermogravimetric analysis (TGA) was conducted in a sample of vitaminB2@P25TiO2NPs using a TA-THA Q5000 equipment. Temperature ramp rate: 10 °C/min, maximum temperature: 1000 °C, under air. Part of the same sample was mounted on conductive copper tape grids and observed through a Carl Zeiss Sigma scanning electron microscope (SEM) with an EDS probe, at the “Laboratorio de Microscopía y Análisis por Rayos X” (LAMARX) of National University of Córdoba (Argentina).
Different dermal cell types have been reported to differ in their sensitivity to nano-sized TiO2 . Kiss et al. exposed human keratinocytes (HaCaT), human dermal fibroblast cells, sebaceous gland cells (SZ95) and primary human melanocytes to 9 nm-sized TiO2 particles at concentrations from 0.15 to 15 μg/cm2 for up to 4 days. The particles were detected in the cytoplasm and perinuclear region in fibroblasts and melanocytes, but not in kerati-nocytes or sebaceous cells. The uptake was associated with an increase in the intracellular Ca2+ concentration. A dose- and time-dependent decrease in cell proliferation was evident in all cell types, whereas in fibroblasts an increase in cell death via apoptosis has also been observed. Anatase TiO2 in 20–100 nm-sized form has been shown to be cytotoxic in mouse L929 fibroblasts. The decrease in cell viability was associated with an increase in the production of ROS and the depletion of glutathione. The particles were internalized and detected within lysosomes. In human keratinocytes exposed for 24 h to non-illuminated, 7 nm-sized anatase TiO2, a cluster analysis of the gene expression revealed that genes involved in the “inflammatory response” and “cell adhesion”, but not those involved in “oxidative stress” and “apoptosis”, were up-regulated. The results suggest that non-illuminated TiO2 particles have no significant impact on ROS-associated oxidative damage, but affect the cell-matrix adhesion in keratinocytes in extracellular matrix remodelling. In human keratinocytes, Kocbek et al. investigated the adverse effects of 25 nm-sized anatase TiO2 (5 and 10 μg/ml) after 3 months of exposure and found no changes in the cell growth and morphology, mitochondrial function and cell cycle distribution. The only change was a larger number of nanotubular intracellular connections in TiO2-exposed cells compared to non-exposed cells. Although the authors proposed that this change may indicate a cellular transformation, the significance of this finding is not clear. On the other hand, Dunford et al. studied the genotoxicity of UV-irradiated TiO2 extracted from sunscreen lotions, and reported severe damage to plasmid and nuclear DNA in human fibroblasts. Manitol (antioxidant) prevented DNA damage, implying that the genotoxicity was mediated by ROS.
Titanium dioxide, commonly known as TiO2, is a chemical compound that has found extensive use in various industries, including food and pharmaceuticals, due to its unique properties. It's primarily used as a colorant, providing a bright white pigment to products, from confectionery to toothpaste. However, when it comes to food, safety is paramount, and the use of titanium dioxide must adhere to strict regulations.
When it comes to vehicle safety, few components are as critical as the braking system. Among the various parts of this system, the brake drum plays a pivotal role, especially in vehicles equipped with drum brakes. Understanding the function and significance of brake drums is essential for both vehicle owners and enthusiasts alike.

Understanding Frozen Rear Drum Brakes Causes and Solutions
Before delving into the painting process, it's important to understand what brake drums are and their role in the braking system. Brake drums are part of a drum brake system, which uses friction to slow down or stop the vehicle. They are typically located on the rear wheels of many vehicles and are essential for effective braking. The surface of brake drums gets extremely hot during operation due to the friction generated with the brake shoes. This heat is a critical factor to consider when thinking about painting.

The installation of brake drum covers can also reduce the need for frequent maintenance. By keeping the drums clean and free from debris, drivers can avoid the premature wear of brake shoes and other critical components. This not only lowers maintenance costs but also ensures that the vehicle continues to perform at its best under various driving conditions.

With the brake shoes properly adjusted, you can now try to remove the brake drum. It may require a gentle tug or a hammer to break it free, especially if it's been on for a long time. If the drum doesn’t budge, double-check the adjustment of the brake shoes.

Another essential part of the drum brake system is the wheel cylinder. Located at the top of the brake assembly, it houses pistons that are activated when hydraulic pressure from the brake fluid is applied. The wheel cylinder pushes the brake shoes outward, creating friction against the drum. This hydraulic mechanism allows for smooth and powerful braking with minimal effort from the driver.

Monteringen av ankerplaten må også være korrekt. Feil installasjon kan føre til ujevn slitasje på bremseskoene, og dermed redusere bremsenes levetid og effektivitet. I tillegg kan en dårlig festet ankerplate føre til vibrasjoner og støy under bremsing, noe som kan være både irriterende og bekymringsfullt for føreren.
However, there are challenges associated with drum brakes that need to be addressed. The design can lead to issues with brake fade, a phenomenon that occurs when the brakes overheat and lose their stopping power. To mitigate this, aircraft equipped with drum brakes often have systems in place to monitor temperature and prevent overheating, ensuring safe operations.

In addition to braking efficiency, the animation can also showcase maintenance aspects. Regular inspection of the brake drums and shoes is essential, as wear can lead to decreased performance. If not properly maintained, drum brakes may suffer from issues like brake fade or uneven wear, which can compromise vehicle safety.
One of the main advantages of drum brakes is their ability to generate a significant amount of friction, even with smaller components. This makes them particularly effective for rear brakes in many older vehicles and in certain trucks. Additionally, drum brakes are less susceptible to water and debris, which can be a significant factor in maintaining braking efficiency. They are also generally more cost-effective, with fewer parts that require regular maintenance.
