This work concerns a new technique to post-modify the catalytic material intended for use in H2O2 direct synthesis. The catalyst chosen was a commercially available 1 wt.% Pd/C. The catalyst was modified with the so-called Catalyst Wet Pretreatment Method (CWPM) that is used to post-modify prepared catalysts with aqueous solutions of NaBr, in different concentrations. The performance of pristine and the pretreated materials were then compared in the H2O2 direct synthesis and characterized before and after the catalytic tests in order to understand the role of the different concentrations of bromide in the CWPM procedure. The surface features of the different catalysts were analyzed with CO chemisorption (metal dispersion and mean particle size), Transmission Electron Microscopy (TEM, for Pd morphology and Pd particle size distributions), Inductive Coupled Plasma (ICP, for Pd content) and Ion Chromatography (IC, for bromide content). Various features of the materials prepared with the CWPM were ...

There is a growing interest in monitoring microplastics in the environment, corresponding to increased public concerns regarding their potential adverse effects on ecosystems. Monitoring microplastics in the environment is difficult due to the complex matrices that can prevent reliable analysis if samples are not properly prepared first. Unfortunately, sample preparation methods are not yet standardized, and the various efforts to validate them overlook key aspects. The goal of this study was to develop a sample preparation method for wastewater samples, which removes natural organic matter without altering the properties of microplastics. Three protocols, based on KOH, H2O2, and Fenton reactions, were chosen out of ten protocols after a literature review and pre-experiments. In order to investigate the effects of these reagents on seven polymers (PS, PE, PET, PP, PA, PVC, and PLA), this study employed µFTIR, laser diffraction-based particle size analysis, as well as TD-Pyr-GC/MS. Furthermore, the

In the quest for renewable and sustainable energy, lignocellulosic biomass, such as herbaceous plants and hardwoods and softwoods, has been shown to be a promising feedstock for the production of second generation biofuels [1]. Lignocellulosic biomass essentially consists of the polysaccharides cellulose and hemicellulose and the aromatic macromolecule lignin. These compounds are present in the plant cell wall as a three-dimensional network giving the plant structure, stability, and resistance.. Pretreatment of the biomass is necessary in order to overcome this recalcitrance and facilitate degradation of polymeric structures [2]-[4]. In particular, the pretreatment methods aim to improve the conversion efficiency of the plant cell wall polysaccharides into fermentable monosaccharides by reducing the cellulose crystallinity or by simply splitting the carbohydrates and lignin for separate downstream processing technologies.. Various pretreatment methods have been developed for this purpose, ...

In order to analyze biological specimens for drugs such as benzodiazepines, it is necessary to perform sample preparation to eliminate matrix interference and ion suppression. Solid-phase extraction is generally the preferred sample preparation technique, in this study Disposable Pipette Extraction (DPX) was utilized. DPX is a fast dispersive solid-phase extraction technique that uses loosely contained sorbent in a disposable pipette tip. The sample is aspirated into the tip where it is actively mixed with the sorbent and forms a suspension. The main advantages of the DPX technology are that the extraction is rapid, minimal solvent waste is generated, and the entire process can be fully automated including introduction of the extract to the chromatographic system. The GERSTEL MPS autosampler performs DPX extractions in approximately 5 minutes using reversed phase (DPX-RP), cation exchange (DPX-CX) or immunoaffinity sorbent material. For determination of target drugs, GC/MS or HPLC/MS/MS are ...

Genotoxic and estrogenic activities in PET-bottled water have been reported. Chemical mixtures in bottled water have been suggested as the source of these toxicological effects. Furthermore, sample preparation techniques, such as solid-phase extraction (SPE), to extract estrogen-like compounds in bottled water are controversial. It has been suggested that inappropriate extraction methods and sample treatment may result in false-negative or positive responses when testing water extracts in bioassays. There is therefore a need to combine chemical analysis with bioassays to carry out hazard assessments. Formaldehyde, acetaldehyde and antimony are clearly related to migration from PET into water. However, several studies have shown other theoretically unexpected substances in bottled water. The origin of these compounds has not been clearly established (PET container, cap-sealing resins, background contamination, water processing steps, NIAS, recycled PET, etc.). [...] Our literature review shows ...

For assays concerning cancer treatment, a two-stage evaluation is contemplated in which both acute cytotoxic and longer term inhibitory effect of a given anti-cancer agent are investigated. The tissue sample technique of the present invention is also useful in assaying expression and/or secretion of various markers, factors or antigens present on or produced by the cultured cells for diagnostic purposes and for using such expression to monitor the applicability of certain candidate therapeutic or chemotherapeutic agents and the

Material Identification Analysis. A detailed analysis of an oil sample is a valuable predictive maintenance tool. In many cases, the analysis enables identification of potential problems before a major repair is necessary, and it has the potential to reduce the frequencies of oil changes. However, there are times when the sample pulled from the system is anything but a traditional oil sample. In these cases, routine oil analysis will not answer the question at hand, and a different approach is required.. Material Identification Analysis is an in-depth investigation designed to identify the root cause of a problem or the origin of foreign material. The analysis employs various analytical and sample preparation techniques to assess the origin of the foreign material and provide recommendations for resolution.. The case studies below illustrate the power of expanding beyond routine oil analysis to identify causes of fluid degradation, mechanical problems, and the anatomy of foreign ...

Miyawakis team has been working on the project since 2011, when they discovered that an aqueous solution of urea was promising for brain tissue optical clearing, but they ran into the tissue damage problem. They have now refined the technique by using a solution which also contains the sugar alcohol sorbitol, as they explain in Nature Neuroscience.. By combining sorbitol in the right proportion with urea, we could create transparent brains with minimal tissue damage, that can handle both florescent and immunohistochemical labeling techniques, and is even effective in older animals, Miyawaki said.. The ScaleS solution also works as a preservative, keeping samples usable for over a year. It can also be combined with other sample preparation techniques: the team used it with a technique for labelling structures that trigger a response from the immune system and another for fluorescent chemical compounds to produce high-resolution images of Alzheimers plaques, which are not detectable in ...

A large amount of variation can be seen in each set of match samples, thus not allowing for differentiation between one producer and another. Sample preparation method 2 was devised to improve uniformity of the sample, and reduce variation. Sample preparation method 2 was used to prepare more samples for U1 and L1. U1 was chosen because there was a large variability in the samples. L1 was chosen because the sample were similar to U1. It was hoped using preparation method 2 the U1 samples would have less variation and be distinct from the L1 samples ...

One important observation about HCP immunoassays is that they occasionally give dilution-dependent results. Dilution dependence arises because the HCPs in the sample (perhaps one or a few HCPs) do not dilute in parallel with those in the standard (a mixture of 1000s of proteins). Limiting amounts of reagents can come in the form of coat, conjugate antibodies, or even Streptavidin-HRP that are associated with antigen excess and non-linear dilution behavior. It is advised to check all reagents to minimize impacts of reagent limitation sample dilution linearity. From a product purity perspective, however, sample dilution non-linearity is not an assay artifact but rather could be an important indication that a large amount of a particular HCP has co-purified with product. Phospholipase B-like 2 (PLBL2) was found to co-purify with multiple CHO-derived Mab products. It may be that this is a common impurity in Mabs produced across the biotech industry since it was found to have co-purified with ...

The importance of accurate sample preparation techniques cannot be overstated--meticulous sample preparation is essential. Often overlooked, it is the midway point where the analytes from the sample matrix are transformed so they are suitable for analysis. Even the best analytical techniques cannot rectify problems generated by sloppy sample pretreatment.Devoted entirely to teaching and reinforcing these necessary pretreatment steps, Sample Preparation Techniques in Analytical Chemistry addresses diverse aspects of this important measurement step. These include:* State-of-the-art extraction techniques for organic and inorganic analytes* Sample preparation in biological measurements* Sample pretreatment in microscopy* Surface enhancement as a sample preparation tool in Raman and IR spectroscopy* Sample concentration and clean-up methods* Quality control stepsDesigned to serve as a text in an undergraduate or graduate level curriculum, Sample Preparation Techniques in Analytical Chemistry also provides an

Lipids are involved in a host of biochemical and physiological processes in corals. Therefore, changes in lipid composition reflect changes in the ecology, nutrition, and health of corals. As such, accurate lipid extraction, quantification, and identification is critical to obtain comprehensive insight into a corals condition. However, discrepancies exist in sample preparation methodology globally, and it is currently unknown whether these techniques generate analogous results. This study compared the two most common sample preparation techniques for lipid analysis in corals: (1) tissue isolation by air-spraying and (2) crushing the coral in toto. Samples derived from each preparation technique were subsequently analysed to quantify lipids and their constituent classes and fatty acids in four common, scleractinian coral species representing three distinct morphotypes (Acropora millepora, Montipora crassotuberculata, Porites cylindrica, and Pocillopora damicornis). Results revealed substantial amounts

Microalgae have recently drawn attention as a potential resource for biofuels generation. In the short term, anaerobic digestion seems the most viable downstream process. Still, microalgae cell wall restrains the hydrolysis, hampering the methane production potential. This work aimed at improving the anaerobic biodegradability of microalgae through different pretreatment methods: microwave, low temperature and high temperature. For the microwave pretreatment, the specific energy was the main parameter affecting biomass solubilisation, increasing up to 800 % compared to untreated biomass. For the low and high temperature pretreatments, temperature was the most important factor, increasing biomass solubilisation up to 1190 and 2140 % in each case. BMP tests showed an increased methane yield after all pretreatments (40-80 %), with the highest results for the microwave pretreatment. In semi-continuous reactors operated at 15 days HRT, the methane production was increased by 30 and 33 % after ...

BACKGROUND: Minimal residual disease (MRD) assessment of hematopoietic neoplasia below 10-4 requires more leukocytes than is usually attainable by post-lysis preparation. However, not all laboratories are resourced for consensus Euroflow pre-lysis methodology. Our study aim was to validate a modified pre-lysis protocol against our standard post-lysis method for MRD detection of multiple myeloma (MM), chronic lymphocytic leukemia (CLL), and B-non Hodgkin lymphoma (B-NHL), to meet demand for deeper MRD assessment by flow cytometry.. METHOD: Clinical samples for MRD assessment of MM, CLL, and B-NHL (50, 30, and 30 cases, respectively) were prepared in parallel by pre and post-lysis methods for the initial validation. Total leukocytes, MRD, and median fluorescence intensity of antigen expression were compared as measures of sensitivity and antigen stability. Lymphocyte and granulocyte composition were compared, assessing relative sample processing stability. Sensitivity of the pre-lysis assay was ...

Woody biomass is one of the most abundant biomass feedstocks, besides agriculture residuals in the United States. The sustainable harvest residuals and thinnings alone are estimated at about 75 million tons/year. These forest residuals and thinnings could produce the equivalent of 5 billion gallons of lignocellulosic ethanol annually. Softwood biomass is the most recalcitrant biomass in pretreatment before an enzymatic hydrolysis. To utilize the most recalcitrant lignocellulosic materials, an efficient, industrially scalable and cost effective pretreatment method is needed. Obtaining a high yield of sugar from recalcitrant biomass generally requires a high severity of pretreatment with aggressive chemistry, followed by extensive conditioning, and large doses of enzymes. Catchlight Energys Sugar process, CLE Sugar, uses a low intensity, high throughput variation of bisulfite pulping to pretreat recalcitrant biomass, such as softwood forest residuals. By leveraging well-proven bisulfite technology and

Solid phase extraction has become a popular tool for analytical method development as a sample preparation technique. Solid phase sorbents can generally extract analytes based on polarity or selectively based on highly specific interactions between the analyte and an immobilized surface molecule. Biomolecular recognition based solid phases utilize antibodies, nucleic acids, and proteins as a secondary affinity layer on a solid phase support for selective analyte extractions and have been used for sample preparation, purification, separations, bioassays, and molecular diagnostics. Polymer supports for solid phase extraction are desirable for their low cost, abundance, chemical inertness, and pH stability. This thesis reports the use of capillary-channel polymer (C-CP) fibers as a solid support modified for selective extraction and on fiber fluorescence detection of nucleic acids and proteins. The polymer fibers are low cost and their unique shape allows them to be easily adapted into a fluidic fiber

Having to reach ever lower limits of detection is a daily challange in modern laboratories. In order to succeed in obtaining sufficiently sensitive analysis methods, sample preparation techniques such as Solid Phase Extraction (SPE) or Liquid-Liquid Extraction are often used as concentration steps. The concentration factor achieved in these cases depends on the amount of solvent used for analyte elution from the SPE cartridge or for liquid extraction. Following the extraction step, further concentration of analytes can be achieved by reducing the amount of solvent left in the extract. This is typically achieved by evaporation. Such a concentration step can contribute significantly to improved limits of detection for the overall analytical method. For the evaporative concentration step, commercially available rotary evaporators as well as custom solutions are widely used. These are mainly stand-alone systems for manual operation. The GERSTEL MultiPosition Evaporation Station (mVAP) in combination ...

In this study various pretreatment methods of sewage sludge inoculum and the statistical process optimization of de-oiled jatropha waste have been reported. Peak hydrogen production rate (HPR) and hydrogen yield (HY) of 0.36 L H2/L-d and 20 mL H2/g Volatile Solid (VS) were obtained when heat shock pretreatment (95 oC, 30 min) was employed. Afterwards, an experimental design was applied to find the optimal conditions for H2 production using heat-pretreated seed culture. The optimal substrate concentration, pH and temperature were determined by using response surface methodology as 205 g/L, 6.53 and 55.1 oC, respectively. Under these circumstances, the highest HPR of 1.36 L H2/L-d was predicted. Verification tests proved the reliability of the statistical approach. As a result of the heat pretreatment and fermentation optimization, a significant (~ 4 folds) increase in HPR was achieved. PCR-DGGE results revealed that Clostridium sp. were majorly present under the optimal conditions.

The three main components of wood, namely, cellulose, hemicellulose, and lignin, can be used in various areas. However, since lignin covalently crosslinks with wood polysaccharides creating networks that is an obstacle for extraction, direct extraction of different wood components in high yield is not an easy matter. One potential approach to overcome such obstacles is to treat the wood with specific enzymes that degrade the networks by specific catalysis. However, the structure of wood is so compact that the penetration of the wood fibers by large enzyme molecules is hindered. Thus, the pretreatment of wood prior to the application of enzymes is necessary, for opening the structure.. One pretreatment method that was performed in this thesis is based on kraft pulping, which is a well-established and industrialized technique. For untreated wood, the wood fibers cannot be attacked by the enzymes. A relatively mild pretreatment was sufficient for wood polysaccharides hydrolyzed by a culture ...

Extrusion pretreatment of lignocellulosic biomasses is a physical continuous pretreatment method for subsequent fermentative ethanol production. Twin-screw elements (conveying, kneading and reverse) have different effects on enzymatic digestibility according to their geometries and functions. The first study evaluated the effects of individual functional screw elements on enzymatic digestibility and found that extrusion enhanced enzymatic digestibility under all tested condition. Reverse and kneading screw elements however resulted in lignin re-distribution over the cellulose fibres, blocked pores (shown via SEM) and resulted in less digestible biomass, compared to conveying screw elements, only. Lignin removal via NaOH reversed this effect and the highest digestibility was found for biomass extruded in the presence of reverse screw elements (the most severe conditions tested in this study). Based on these finding a process was developed for separating xylose from lignocellulosic biomass (steam-exploded

The Laser Ablation of Microparticle Aerosol (LAMA) process provides a method for generating high yields of aerosolized nanoparticles (NPs) that are then accelerated through a nozzle and impacted onto substrates. The process allows nanostructured films and patterned lines to be directly written onto substrates at room temperature. Using the LAMA process, we have demonstrated the ability to produce thick patterned deposits with densities ranging from 60-70% in the as-deposited state. After deposition, the lines were densified using pressure-assisted sintering and the microstructures and strengths of the films were investigated. Pressure-enhanced sintering resulted in densification and strong bonding at processing temperatures of 100-175°C and pressures of 100-600 MPa. Mechanisms for sintering at low temperatures are discussed. ...
