Effects of Multidimensional Carbon-Based Nanomaterials on the Low-Carbon and High-Performance Cementitious Composites: A Critical Review.

Cementitious composites are ubiquitous in construction, and more and more research is focused on improving mechanical properties and environmental effects. However, the jury is still out on which material can achieve low-carbon and high-performance cementitious composites. This article compares the mechanical and environmental performance of zero-dimensional fullerenes, one-dimensional carbon nanotubes (CNTs), two-dimensional graphene oxide (GO), and three-dimensional nano-graphite platelets (NGPs) on cementitious composites.

Silver nanoparticles synthesized using leaf extract of exhibit enhanced antimicrobial efficacy than the chemically synthesized nanoparticles: A comparative study.

A wide variety of methods have synthesized silver nanoparticles (Ag-NPs) in the recent past; however, biological methods have attracted much attention over the traditional chemical synthesis method due to being non-hazardous and eco-friendly. Here, a detailed and systemic study was performed to compare two different synthesis routes for Ag-NPs, that is, the chemical and the biological; their possible outcomes have also been described. Ag-NPs were synthesized chemically (cAg-NPs) using a chemical reductant and biologically (bAg-NPs) by using aqueous leaf extract of (neem).

Ampicillin-augmented Silver Nanoparticles for Synergistic Antimicrobial Response: A Promising Therapeutic Approach.

Aims: Globally, scientists are working to find more efficient antimicrobial drugs to treat microbial infections and kill drug-resistant bacteria.

Background: Despite the availability of numerous antimicrobial drugs, bacterial infections still pose a serious threat to global health. A constant decline in the effectiveness of antibiotics owing to their repeated exposure as well as a short-lasting antimicrobial activity led to the demand for developing novel therapeutic agents capable of controlling microbial infections.

Functionalization of Inorganic Nanoparticles to Augment Antimicrobial Efficiency: A Critical Analysis.

Background: Nanoparticles (NPs) or nanomaterials being used widely in various fields have occupied prime importance in biomedical sciences, owing to their unique size dependent properties which make them superior to bulk materials. One of the major applications of NPs in biomedical field is their therapeutic application including antimicrobial activity.

Objective: It is already well known that certain NPs such as silver, zinc oxide, copper, iron etc.

Aloe emodin, an anthroquinone from Aloe vera acts as an anti aggregatory agent to the thermally aggregated hemoglobin.

Aggregation of proteins is a physiological process which contributes to the pathophysiology of several maladies including diabetes mellitus, Huntington's and Alzheimer's disease. In this study we have reported that aloe emodin (AE), an anthroquinone, which is one of the active components of the Aloe vera plant, acts as an inhibitor of hemoglobin (Hb) aggregation. Hb was thermally aggregated at 60°C for four days as evident by increased thioflavin T and ANS fluorescence, shifted congo red absorbance, appearance of β sheet structure, increase in turbidity and presence of oligomeric aggregates.

Effect of contact angle on the orientation, stability, and assembly of dense floating cubes.

In this paper, the effect of contact angle, density, and size on the orientation, stability, and assembly of floating cubes was investigated. All the cubes tested were more dense than water. Floatation occurred as a result of capillary stresses induced by deformation of the air-water interface.
