The purpose of this paper is to check an applicability of aluminized basalt fabrics for production of gloves protecting simultaneously against thermal and mechanical factors.

Six variants of protective gloves were manufactured using two different glove constructions: more simple and cheaper with the anatomical thumb arrangement (model A), and more ergonomic one with so called “distance gussets” (model B). Aluminized basalt fabrics were contained in the back side of all variants and in only one variant of palm side. Then the protective properties against thermal and mechanical factors were measured according to the up-to-date standards.

The fulfillment of contact heat requirement was achieved for all glove variants at 100°C. Application of aluminized basalt fabrics in the glove back side allowed obtaining the fourth performance level in the case of resistance to small metal splashes and assuring the highest protection against the radiant heat and small metal splashes. Fulfillment of standard requirements for all examined mechanical parameters was achieved and significantly higher values than reqired for the highest performance level were registered.

The further research including upscalling strategy as well as industrial conditions requirements should be taking into account for basalt textiles development. Moreover functionalization of basalt yarns and fabrics seems to be promising feature.

The preliminary utility trials were done and registered results are very promising, shows that this kind of gloves will be cheaper than produced so far and could be used in the glass, welder companies.

The basalt textiles applied for protective gloves or other personal protective equipment can ensure safety at work for end users operating in mechanical and thermal risk scenarios.

Up till now the basalt fabrics have not been recognized as a material for the personal protective equipment, they were used mostly for technical purposes.

Catalytic reforming has grown rapidly during the past six years, reaching over a million barrels daily. This acceptance is largely due to the effectiveness of catalytic reforming as a source of low‐sulphur, high‐octane motor fuels; aromatics for petro‐chemicals and low‐cost hydrogen are valuable by‐products. Some ten competitive processes are available to the refiners. Of the processes available, those using a platinum‐type catalyst have found the widest acceptance. Of the nearly 200 units in operation or under construction, over 90% use a platinum‐containing catalyst.

The liquid lithium-lead breeding blanket in the international thermonuclear experimental reactor is one of the major international concerns and one of the potential conceptual designs for the fusion reactor.

Reduced activation ferritic-martensitic steels are being considered for application in future fusion technology as the relevant structural material, which will be in contact with the lithium-lead breeding material.

According to the test results, comprehensive evaluations of these findings have been performed to determine the wastage rates and mechanisms for the conceptual design of the fusion reactor.

From micro to macro, systematic cross-scale models are needed for the understanding of corrosion/wastage mechanisms in fusion reactor engineering applications.

A completely new particle size analyser from Malvern Instruments employs a novel aerodynamic principle to separate particles in samples of dry powders or suspensions.
