Bio-active restorative materials as alternative pit and fissure sealants in pediatric and preventative dentistry: In vitro investigation
(MedCrave, 2017)BACKGROUND: It has been more than 40 years since the pit and fissure sealants were first used clinically. During this time, pit and fissure sealants have been shown to be effective in reducing the risk of occlusal caries. AIM: ... -
Bio-synthesised black α-Cr2O3 nanoparticles; experimental analysis and density function theory calculations
(Elsevier, 2021)A selective single phase black α-Cr2O3 nanoparticles was bio-synthesised via simple straight-forward green synthesis approach. The process involves extraction of phytochemicals contained in peels of sweet potatoes. Extraction ... -
Bioaccumulation of total mercury in the earthworm Eisenia andrei
(SpringerOpen, 2016)Earthworms are a major part of the total biomass of soil fauna and play a vital role in soil maintenance. They process large amounts of plant and soil material and can accumulate many pollutants that may be present in ... -
Bioactive Materials for Temporary Restorations: From Design to Applications
(Ann Materials Sci Eng, 2015)Objective: To examine the effect of Protemp4:chitosan:nanodiamond bioactive containing modified materials and compare the protective activity of the propolis (Brazilian) and copaiba oil as bio-active additives to compare ... -
Bioassay-guided fractionation leads to the detection of cholic acid generated by the rare thalassomonas sp.
(Pubmed, 2023)Bacterial symbionts of marine invertebrates are rich sources of novel, pharmaceutically relevant natural products that could become leads in combatting multidrug-resistant pathogens and treating disease. In this study, ... -
Biocontrol potential of bacillus subtilis and bacillus tequilensis against four fusarium species
(Pathogens, 2023)The use of biological control agents as opposed to synthetic agrochemicals to control plant pathogens has gained momentum, considering their numerous advantages. The aim of this study is to investigate the biocontrol ... -

Biodegradable ceramics consisting of hydroxyapatite for orthopaedic implants
(MDPI, 2017)This study aims to analyze hydroxyapatite (HAP) coatings enriched with Mg and Ti prepared by a magnetron sputtering technique on Ti6Al4V substrate. For preparation of the coatings, three magnetron targets (HAP, MgO and ... -
Biodegradation of high-concentration isopropanol by a solvent-tolerant thermophile, Bacillus pallidus
(Springer Verlag, 2002)The aerobic biodegradation of high-concentration, to 24 g l –1 , 2-propanol (IPA) by a thermophilic isolate ST3, identified as Bacillus pallidus , was successfully carried out for the first time. This solvent-tolerant B. ... -
Biodiversity: so much more than legs and leaves
(AOSIS OpenJournals, 2013)Microorganisms inhabit virtually every possible niche on Earth, including those at the outer envelope of survival. However, the focus of most conservation authorities and ecologists is the ‘legs and leaves’ side of biology ... -
The biofuels boom and bust in Africa: A timely lesson for the New Alliance initiative
(Institute for Poverty, Land and Agrarian Studies, University of the Western Cape, 2015)Policies promoting biofuels development through financial incentives in Europe and in the United States of America are major drivers of the ‘land rush’ in many African countries. Yet, we know that most of the first projects ... -
