Abstract: The corrosivity of indoor atmospheres is usually evaluated according to the ISO 11844-1 standard, utilizing specimens of different metals. However, the sensitivity of this setup is not sufficient to the presence of specific organic pollutants, such as acetic and formic acid or formaldehyde. [..] Read more

Abstract: High sensitivity of lead to organic compounds leads to degradation of lead artifacts stored in the museums or archives together with organic materials (wood, glue, leather, paper, plastic, etc.). Protection of the lead stored under adverse conditions (environment polluted by organic compound, mainly acetic acid) is based on the use of corrosion inhibitors. [..] Read more

Abstract: The paper deals with the corrosion behavior of steels with reduced effective chromium content in the matrix, with the intent to estimate their long-term behavior in low aggressive environments, typical for the secondary and primary circuits of nuclear power plants. Materials for this research were steels with varying characteristics of influence of effective chromium content precipitation of chromium carbides or spinodal breakdown of chromium / martensitic steels, creating other types of chromium-rich phases, e.g. [..] Read more

Abstract: The organ cabinet represents a specific corrosion environment with a high concentration of organic compounds that are released into the environment during the degradation of wood, glues and varnishes used in the production of the organ cabinet. Moreover, most of the metals from which organ pipes are made are highly sensitive to organic substances. [..] Read more

Abstract: Protection of the lead and lead-tin alloys stored in museum and archive depositories under adverse conditions (environment polluted by organic compound, mainly acetic acid) is based on the use of protective coatings (corrosion inhibitors, waxes and varnishes). The aim of this work was to test long-term stability and inhibition efficiency of mainly used protective coatings and final visual appearance of treated lead and lead-tin alloy surface. [..] Read more

Abstract: The paper characterizes selected lead-based wastes occurring in the metalworking industry, such as wire manufacturers using lead baths in the heat treatment process. Attention is focused on the possibility of using the proportion of lead in direct metal form, which can occur in certain types of waste. [..] Read more

Abstract: Testing of material fatigue properties belongs to important material examinations. A standard fatigue measurement is mostly a time-consuming and expensive experiment, among others due to a number of samples needed. [..] Read more

Abstract: Leading organizations agree on the need for a structured methodology for using performance measurement information to help set agreed-upon performance goals, allocate and prioritize resources, confirm or change current policy or program directions to meet those goals, and report on the success in meeting those goals. The evaluation of enterprise performance forms an inevitable precondition for maximum business success achievement. [..] Read more

Abstract: It is well documented that the addition of antimony in pure lead increases tensile strength and reduced elongation. The goal of the present work is to identify the cause of these phenomena by investigation of the effects of the addition of Sb (1.25 wt.%) on the structure of pure continuously cast lead and lead alloy rods. [..] Read more

Abstract: Lead bulls are often stored in an inappropriate environment with the presence of organic acids to which lead is sensitive. The aim of this work was to test compounds inhibiting the lead corrosion due to acetic acid vapours. [..] Read more

Abstract: Currently, the hot topic in restoration and conservation of metals is the application of corrosion inhibitors intended for protection of lead. Our research aims in selection of suitable protection system which would be applicable for conservation of historical lead seals. [..] Read more

Abstract: Thanks to the specific sensitivity of lead to volatile organic compounds (VOC), it is possible to use lead as an indicator of contamination of the indoor atmosphere of depositories of archives and museums where VOCs are typical pollutants. The classification of corrosion aggressiveness of indoor environments based on the determination of the corrosion rate of reference metals is given by the standard ISO 11844-1 which was recently supplemented with lead. [..] Read more

Abstract: Aim of this work is to test possibility to utilize colorimetric spectroscopy for monitoring the corrosion of lead and tin-lead alloys. And furthermore method suitability for preliminary corrosion evaluation of cultural heritage objects. [..] Read more

Abstract: Silicon nanowires (Si NWs) were grown from Si wafer upon thermal annealing in the presence of catalytic gold layer. The Si substrate coated with 100 nm thick Au sputtered layer was thermally annealed at 1000 °C for 60 min in argon and hydrogen atmosphere at 8 kPa. [..] Read more

Abstract: One of the main concern in the development of the Gen IV lead-cooled fast reactors (LFRs) is the compatibility of the candidate structural steels and cladding materials with the heavy liquid metal (HLM). Structural materials compatibility in conditions relevant to plant operation is of primary importance to safety. [..] Read more

Abstract: A lead was used in the past in a variety of applications for example for roofs of churches, garden ornaments, lead seals, and organ pipes. Lead alloys are susceptible to a corrosion attack in an environment containing volatile organic compounds especially acetic acid vapors. [..] Read more

Abstract: Technical standards are developed by a panel of experts, within a technical committee in frame of various standardisation organisations. The most important are ISO and ESS - the European standardization system (ESS) comprises the three recognised European Standards Organisations (ESOs) - CEN, CENELEC and ETSI. [..] Read more

Abstract: Mechanical testing and cyclic fatigue testing belong to the important material examinations. Standard fatigue testing is mostly time-consuming and needs a number of identical samples that makes the testing expensive. [..] Read more

Abstract: Metal and organometal halide perovskites, an emerging class of direct bandgap semiconductors, have attracted great attention lately. Lead halide perovskites were recognized as promising candidates for future lighting applications, due to their high quantum yield, narrow full width at half maximum (FWHM), and wide color gamut.

Abstract: Studying the nonlinearities in the resonant mode one may face thermo-optical effects due to sample overheating, occurring upon exposure to high-frequency repetition rate probing pulse. If present, thermo-optical contribution to the refractive index are extremely hard to separate from the electronic contribution. [..] Read more
