Searching for innovations. Self-cleaning surfaces.

Searching for innovations KRUKIEWICZ K. Please cited as: CHEMIK 2011, 65, 11, 1218-1223 Nowadays, almost at every step we are attacked with news about discoveries, inventions aiming to change the everyday life. Some of them make life more comfortable, others make the everyday duties easier or provide entertainment. This article describes histories of inventions which are frequently used nowadays: contact lenses, self-cleaning surfaces and OLED displays. They are much older than we expect, as well as much more interesting. Keywords: innovations, contact lenses, lotus effect,...

Genetically modified crops and food: pros and cons

Genetically modified crops and food: pros and cons LISOWSKA K. Please cite as: CHEMIK 2011, 65, 11, 1193-1203 In Poland genetically modified crops are not regulated by law. Polish Parliament has been discussing the proposal of a new act concerning genetically modified organisms (GMO) since 2009 and did not manage to finalize before the end of its term. Regulations concerning GMOs were also contained in the seed act, but it was vetoed by Polish President. There is also a great debate in the...

The phenomenon of singlet oxygen

The phenomenon of singlet oxygen KRUKIEWICZ K. Please cite as: CHEMIK 2011, 65, 11, 1190-1192 Singlet oxygen has been the subject of intensive research for almost 80 years. Its unusual properties, like high reactivity and oxidizing properties, make it a versatile chemical reagent. Photogeneration is considered as the most effective method of singlet oxygen formation, though it needs to be conducted in situ due to the short lifetime of that form of oxygen. Singlet oxygen has been already applied in the area of medicine...

Micromasters of the Earth. Bacteria.

Micromasters of the Earth WĘGRZYN A. Please cite as: CHEMIK 2011, 65, 11, 1182-1189 Bacteria are the most common and numerous organisms on the planet. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. Bacteria are ubiquitous in every habitat on Earth, growing in soil, water, the live bodies of plants and animals as well as in hot springs, radioactive waste and hydrothermal vents. This article presents the most interesting microorganisms and possibilities...

Biofuels ? have we exhausted all the possibilities?

Biofuels ? have we exhausted all the possibilities? KIJEŃSKA M., KIJEŃSKI J. Please cite as: CHEMIK 2011, 65, 11, 1169-1176 Given the projected 54% increase in world energy consumption in the period 2001-2025 and the depletion of mineral resources for satisfying energy needs is essential to explore the possibility of replacing conventional sources of renewable energy. The article discusses the concept of biofuels, such as liquid substances, gases and solid fuels produced from biomass. Identified three generations of biofuels and the conditions necessary to...

Analysis of the possibility of using mechanical processes in municipal waste segregation LIGUS G. Please cite as: CHEMIK 2011, 65, 11, 1161-1168 The paper brought closer to the basic mechanical processes that can be used in systems of mixed municipal waste management, with particular emphasis on their location in the functioning of waste management plants. The possibilities of separation of waste fractions for recycling or recovery of heat, characterized the various devices and processes used in the technology of mechanical sorting of waste. The article...

Application of flax, hemp and nanofibers for air protection against micro-organisms

Application of flax, hemp and nanofibers for air protection against micro-organisms TYROLCZYK E., GRAJEK K., ŁOCHYŃSKA M. Please cite as: CHEMIK 2011, 65, 11, 1147-1160 In case of presence of air pollution with harmful microorganisms it seems reasonable to make use of specialist filtering systems. As a result of using properly selected materials the filtration systems can be 100% biodegradable. Surface modification of the filter with nanofibers brings reduction in mesh size and increases the specific surface area of the filter. This leads to...
