This paper presents the results of practical mechanical tests of motor oils, their specifications and characteristics and the effect of their physical and chemical properties on the performance of the engine. The performance of the engine has a strong relation with the engine oil type and efficiency. The degree of stability of oils properties is very important because if oil or lubricants lose their properties, mechanical and chemical excessive corrosion of the motor metals may occur. Consequently, damage occurs to one or more parts of the engine, thereby the system is breaking down where the cost of downtime is too expensive. It has been found that a higher viscosity value is not the optimum as it increases temperature and energy consumption due to frictional losses. The values required for viscosity is the ideals that gives the stable results regardless temperature variations under any conditions of operation, at which the power losses are minimal and the fuel economy is optimal.

Near-infrared spectroscopy has many advantages that make it a widely used analitical method in the different areas, like agricultural and food industry as well. In wheat quality control rheological characteristics of dough made from wheat flour are as important as physical and chemical properties too. In this work we examined rheological properties of wheat flour samples by alveograph, and spectral data of the same samples were collected by FOSS Infratec 1241 instrument. Modified partial least squares analyses on NIR spectra were developed for two alveograph parameter (P/L és W) to get calibration equations.

As the nanotechnology rapidly develops, the combination of nanotechnology and biotechnology to build nanoparticles with biological functionalization has brought new opportunities for the development and application of biomedical diagnosis. Many new non-viral drug/gene vectors were constructed by using nanoparticles as drug/gene carriers, especially by making conventional inorganic materials into nanoparticles and performing functional modifications. In this paper, the physical and chemical properties, preparation methods and application in drug/gene transport of several nanomaterials including mesoporous silica nanoparticles, gold nanoparticles, dendrimers, graphene oxide and carbon nanotubes are reviewed respectively. At the same time, the merit and dismerit of different nanocarriers and their application scenarios are compared. It has been found that the excellent biocompatibility and large specific surface area of inorganic nanomaterials have great potential for drug/gene delivery. Although there are many bottlenecks and challenges for nanomaterials to settle during drug delivery development and industrial production, the improvement of inorganic nanomaterials and the development of new nanocarriers can promote the wider progress of nanocarriers in drug/gene transport.

Nanoparticles are zero-dimensional nanomaterials and, based on their nature, they can be categorized into organic, inorganic, and composites nanoparticles. Due to their unique physical and chemical properties, nanoparticles are extensively used in a variety of fields, including medicine, pharmaceutics, and food industry. Although they have the potential to improve the diagnosis and treatment of brain diseases, it is fundamentally important to develop standardized toxicological studies, which can prevent the induction of neurotoxic effects. The focus of this review is to emphasize both the beneficial and negative effects of nanoparticles on brain health.

Hierarchical ZrO2 nanorods have recently received considerable attention due to their special physical and chemical properties. However, traditional preparation methods are involved in expensive equipment, complicated process and high production cost. Here we report a simple hydrothermal approach to prepare hierarchical ZrO2 nanorod. The results show that as-synthesized products are composed of many nanorods with 80~150 nm in diameter and 15~20 μm in length. After annealing, the final product was involved into hierarchical monoclinic ZrO2 (m-ZrO2) nanorods, namely, the big nanorod was made up of many small nanorods with 20~30 nm in diameter and 300~500 nm in length. The possible formation mechanism was proposed based on a series of chemical reactions and the natural properties of zirconium.

The objective of this work was to evaluate the influence of different proportions of jambolan pulp, sugar and water on the physical and chemical characteristics to obtain information that allows the use of jambolan and, consequently, the evaluation of these fruits. Six jambolan nectar formulations were established through Simplex design. Ingredients significantly affected luminosity (32,14-34,24), apparent viscosity (7.8-73.8 cP), total soluble solids (8.87-26.43 °Brix), titratable acidity (0.55 -0.83g citric acid 100g-1) and the TSS / TA ratio (16.05-34.96) in jambolan nectars. Jambolan nectar with 55g 100g-1 of jambolan pulp, 15g 100g-1 of sugar and 30g 100g-1 of water has the highest desirability in relation to physical and physicochemical properties, 85.1% DPPH inhibition, 10526.12 μg TE mL-1 and 27014.25 μmol TE mL-1 by ABTS and ORAC method, respectively. It could be concluded that it is possible to produce jambolan nectar which can increase the possibilities of applying fruit as an ingredient in the food industry.
