Résumé :

Introduction. One type of concrete corrosion is caused by the chemical interaction of amorphous silica in aggregates with alkalis in the cement paste. This process develops slowly, and damage to the concrete is often detected only several years after construction is completed. Initially, damage caused by alkali-silica reaction was observed in large structures such as dams, bridges, and road pavements. Repairing and protecting damaged concrete structures is considered a complex process. The present paper addresses issues related to the prevention and protection of structures affected by this ty

Résumé :

Micro- and nanoparticles of β-Ga2O3 are synthesized as a result of chemical reaction of an aqueous solution of gallium nitrate and various alkalis: ammonia, sodium, potassium, and lithium hydroxides. It is shown that particles morphology depends on the type and concentration of alkali. The use of microwave treatment of ammonia containing solutions made it possible to change the shape of particles from ellipsoidal to parallelepiped while maintaining their size. In contrast to the synthesis with ammonia, for other alkalis dispersed particles were obtained only at a ratio of alkali to gallium nit

Résumé :

The best known and effective methods for the reduction of the negative effects of an alkali–silica reaction in concrete include the application of mineral additives with an increased aluminium content and reduced share of calcium, as well as chemical admixtures in the form of lithium compounds. Because both aluminium and lithium ions increase the stability of reactive silica in the system with alkalis, it is possible to presume that the application of both corrosion inhibitors together will provide a synergistic effect in the ASR limitation.

Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramics, lithium grease lubricants, flux additives for iron, steel and aluminium production, lithium metal batteries, and lithium-ion batteries.

Résumé :

When oxide glasses are modified by dissimilar alkali ions, a maximum in the electric resistivity or the expansion coefficient appears, called the mixed-alkali effect (MAE). This paper reviews the MAE on the thermal, elastic, and vibrational properties of the mixed-cesium lithium borate glasses, x{(1−y)Cs2O-yLi2O}-(1−x)B2O3. For the single-alkali borate glasses, xM2O(1−x)-B2O3 (M = Li, Na, K, Rb, and Cs), the glass transition temperature, Tg = 270 °C, of a borate glass monotonically increases as the alkali content x increases. However, for the mixed-cesium lithium borate glasses the Tg shows th

Résumé :

Reaction of functionalized alkyl 2-alkynoates (e.g., 13–19) with lithium (trimethylstannyl)(cyano)cuprate (3) under two sets of carefully defined experimental conditions provides, efficiently and stereoselectively, either alkyl (Z)- or (E)-3-trimethylstannyl-2-alkenoates (e.g., 23, 26–31 and 24, 32–37, respectively).

Résumé :

The aim of this paper is to study the influence of lithium-slag and fly ash on the workability , setting time and compressive strength of alkali-activated slag concrete. The results indicate that lithium-slag and fly-ash can ameliorate the workability, setting time and improve the compressive strength of alkali-activated slag concrete，and when 40% or 60% slag was replaced by lithium-slag or fly-ash, above 10 percent increase in 28-day compressive strength of concrete were obtained.

Résumé :

A novel alkyl lithium-based initiator with relatively large steric hindrance, tert -butyldimethylsiloxydimethylpropyl lithium (TBDMSODPrLi), was designed and synthesized. By using TBDMSODPrLi, hydroxyl-terminated polybutadiene (HTPB) was prepared via anionic polymerization. The macromolecular structure of HTPB was characterized and verified by FTIR and 1 H-NMR. It was found that 1,4 unit content in HTPB initiated by TBDMSODPrLi was significantly higher (over 90%) compared to a HTPB (1,4 unit content of 70%) initiated with another initiator possessing smaller steric hindrance.

Résumé :

Abstract Within the framework of these studies, an electrochemical method for the synthesis of highly dispersed powders of copper compounds in aqueous solutions of alkalis is presented. The factors influencing the rate of production of nanoscale copper (II) oxide particles are determined. It is shown that during the anodic oxidation of copper by direct current, the speed of highly dispersed powders formation depends on current density, the nature of alkali cation, and the concentration of electrolyte solution. The mass loss of copper electrodes in NaOH solution is higher than in solutions of p

Résumé :

Four types of alkyl (ethyl, propyl, isopropyl, n-butyl) bacterial cellulose with the degree of substitution 0.14-2.64 were prepared through etherification of bacterial cellulose with alkyl bromide in dimethyl acetamide/lithium chloride solution under ambient pressure at 50°C, with sodium hydride as the acid binding agent. The products were characterized through FTIR, NMR, and elemental analysis. The solubility of the derivatives in chloroform, ethanol, DMSO, and toluene/ethanol (V/V 3/7) was tested.
