High early strength concrete incorporating waste derived nanomaterials for sustainable construction.

This paper contributes to the expanding knowledge base on nanomaterial-enhanced cementitious composites, offering valuable insights for developing high-performance, sustainable concrete solutions. The study assessed the effects of three different types of nanomaterials-nano clay (NC), nano silica (NS), and nano cellulose (NCel)-on the compressive strength of high-early-strength concrete (HESC) through both experimental studies and a 2 factorial design. Incorporating nanomaterials into the HESC matrix led to a decrease in workability, with NCel demonstrating the least impact on this property across all studied replacement percentages.

An impedimetric approach for determination of ammonium using silver/poly-1-aminoanthraquinone/carbon paste electrode.

Here, we present the electrochemical determination of ammonium in water samples, emphasizing the importance of accurate and precise assessment of its concentration. The modified electrode used in this study was fabricated through the anodic polymerization of 1-aminoanthraquinone (1-AAQ) and deposition of silver particles into a carbon paste electrode. The fabrication process involved cyclic voltammetry in a 0.

Antimycotic prophylaxis with multispecies probiotics against oral candidiasis in new complete denture wearers: A randomized clinical trial.

Statement Of Problem: Changes in the oral microbiota of new complete denture wearers are the main cause of oral candidiasis. The drawbacks associated with traditional antimycotic therapies, especially drug resistance, have led to the search for potent therapeutic and prophylaxis agents with less harmful effects, including probiotics. However, investigation of the prophylaxis and preventive effects of probiotics on new complete denture wearers are lacking.

Synergistic optical sensing: Selective colorimetric analysis of copper in environmental and biological samples.

A groundbreaking optical sensing membrane has been engineered for the accurate assessment of copper ions. The pliable poly(vinyl chloride) membrane is formulated through the integration of sodium tetraphenylborate (Na-TPB), 4-(2-hydroxy-4-nitro azobenzene)-2-methyl-quinoline (HNAMQ), and tri-n-octyl phosphine oxide (TOPO), in conjunction with o-nitrophenyl octyl ether (o-NPOE). The sensor membrane undergoes a thorough investigation of its composition to optimize performance, revealing that HNAMQ serves a dual role as both an ionophore and a chromoionophore.
