Nitrocellulose varnishes (pyroxylin, collodion wool, nitrocellulose) is produced as follows:

500% nitrocellulose is dissolved in a mixture of 9 liters of amyl acetate and 9 liters of gasoline. Some advise simply dissolving nitrocellulose in amyl acetate alone. You can also use as a solvent a mixture of ether and alcohol with the addition of boric acid. In addition, zapon varnishes are obtained by dissolving nitrocellulose in a mixture of amyl acetate and amyl alcohol, using the following weight ratios:

1st recipe:

Nitrocellulose 100 wt. hours;
Amyl acetate 150 wt. hours;
Amyl alcohol 150 wt. h.

2st recipe:

Nitrocellulose 100 wt. hours;
Amyl acetate 400 wt. hours;
Amyl alcohol 400 wt. h.

Zaponovy varnish can also be obtained by dissolving 8 wt. hours of pyroxylin in 40 wt. including an alcohol solution of camphor with the addition of iodoform.

The following mixtures also gave good results.

1st recipe:

Methyl alcohol 32 wt. hours;
Amyl, propyl or butyl acetate 18 wt. hours;
Amyl alcohol 32 wt. hours;
Soluble pyroxylin 5 wt. h.

2st recipe:

Methyl alcohol 44 wt. hours;
Amyl alcohol 10 wt. hours;
Propyl or butyl alcohol 20 wt. hours;
Camphor 5 wt. hours;
Soluble pyroxylin 10 wt. h.

When using collodion cotton, pour over and impregnate 10 wt. hours of dry cotton wool 35 wt. hours of ether, then add 60 wt. h. 95 ° alcohol. After the subsequent dissolution and clarification, it is drained from the precipitate and dissolved in a clear solution with stirring from 4 to 6 wt. including camphor.

In general, the following proportion can be used for this recipe:

Collodion cotton wool 8-10 wt. hours;
Ether or alcohol 100 wt. hours;
Castor oil 2-4 wt. hours;
Rosin 4-10 wt. h.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Nanofluid for oil production 21.09.2020

Researchers at the University of Houston have demonstrated that low-cost and non-toxic nanofluids can be used to efficiently extract even heavy, highly viscous oil from reservoirs.

So-called heavy oil - the result of the molecular structure of oil - makes up 70% of the world's oil reserves and will be needed to meet growing energy demands until clean energy sources are developed and used everywhere. Modern oil extraction technologies using steam are expensive and damaging to the environment.

However, scientists have developed a nanofluid that helps to extract oil from the reservoir using the following mechanisms.

The chemical reaction that occurs when the sodium nanoparticles come into contact with the water in the reservoir generates heat, acting in the same way as steam injection and other heat-based methods to push oil out of the reservoir, without the need for external - and greenhouse gas - producing - heat source.

The nanofluid also reacts to form sodium hydroxide, a chemical commonly used in alkaline flooding in oil fields. Sodium hydroxide can cause movement in the oil and cause a viscosity-lowering reaction.

The third reaction produces hydrogen gas that can be used for waterflooding, another common oil recovery method.

The sodium nanomaterials are dispersed after the reaction, thus not damaging the environment. Optimal concentrations will vary depending on individual development conditions.

Sodium is highly reactive with water. This suggests that it may be useful for enhanced oil recovery. However, this also complicates its preparation - exposing it to water too early will result in failure. The researchers solved this problem by preparing sodium nanoparticles in silicone oil, allowing the substance to disperse throughout the tank before it comes into contact with the water in the tank, causing fewer chemical reactions over a larger area. It is also possible to disperse sodium nanoparticles in other solvents, including pentane and kerosene, or even blend them with polymers or surfactants to achieve higher oil recovery.

While the paper focuses on using the nanofluid to increase heavy oil recovery, the scientists note that it could also be used in light oil production and for more general domestic purposes such as cleaning pipes clogged with grease.
