Aluminum tolerance, growth, and organic acid exudation in rambutan (Nephelium Lappaceum)
(2012)
A randomized complete block design experiment with six aluminum (Al) concentrations was carried out to evaluate the effect of aluminum on nutrient content, dry matter (DM) production and Al-induced organic acid exudation ...
Design, improvement in the construction and analysis of the electrical efficiency of a microbial fuel cell
(2012)
The scientific community is in urgent need to develop instrumentation capable of using alternate energy sources which help to solve the petroleum crisis that world is encountering today. Among the proposed technologies, ...
Diffracted light contrast: A chemical application
(2010)
There is a tremendous interest in the development of microscopy tools that can provide important information at a cost significantly smaller than those offered by traditional electron microscopes. With the purpose of ...
Expression, isolation, purification, and characterization of recombinant human SFi1p1-2
(2013)
Homo sapiens Sfi1 (Hs Sfi1) is a 1242 amino acid protein containing 23 tandem binding sites for a calcium binding protein known as centrin. Hs Sfi1p₁₋₂ is an 8,592 Da peptide that corresponds to the first two centrin binding ...
Crystal structures of hemeproteins: Sulf and H2S myoglobin derivatives and Lucina pectinata Oxy (HbII-HbIII) and Oxy (HbIII-HbIII) systems
(2020-04-21)
As a gasotransmitter, hydrogen sulfide (H2S) biochemistry in humans is of pivotal importance. One relevant reaction of H2S in our bodies is its interaction with hemeproteins. The threshold of its beneficial/harmful effects ...
Development of a fast chromatographic method for the detection of organoarsenic antimicrobials
(2010)
New protocols were developed for the routine analysis of the organoarsenic drugs roxarsone (4-hydroxy-3-nitrophenylarsonic acid), p-arsanilic acid, and acetarsone (Nacetyl-4-hydroxy-m-arsanilic acid) based on ion-pairing ...
Cleaning validation applications using Mid-Infrared quantum cascade laser spectroscopy
(2017)
According to the Recall Root Cause Research (RRCR), an initiative governed by the U.S. Food and Drug Administration (FDA), the contamination of pharmaceutical products is an alarming cause of public concern. During 2015, ...
Surface characterization of chemically modified electrodes with gold nanoparticles and (His)6-rHbI from Luciana pectinata for H2S Detection
(2019-05-15)
The recombinant polyhistidine-tagged hemoglobin I ((His)6-rHbI) from bivalve Lucina pectinata is an ideal biocomponent for a hydrogen sulfide (H2S) biosensor due to its high affinity for H2S. Nowadays it is clear that H2S ...
TNT and MO photodegradation in deionized and salt waters with visible light assisted by photoactivation of modified TiO2
(2020-05-22)
The release of munitions during military combat events or training exercises represents an alarming situation to the marine environment. Since nitroaromatic compounds (NACs) that are released from these weapons remain in ...
Scanning tunneling microscopy studies of Alkyl Thiols on real surfaces
(2008)
The development of new materials has been the focus of the attention of researchers over the last decades. With the arrival of the new century, nanotechnology has played an important role in the creation or reinvention of ...
