Abstract Textile sludge is a waste from the effluent treatment of textile laundries and its incorporation into alternative materials has been proposed as a possibility for its disposal. A systematic search was carried out in literature from this perspective, aiming to observe concentrations of waste material and its preparation, matrices used, technological performance and immobilization of textile waste. The matrices used were mortars, concretes and ceramic bricks, in general, deleterious effects were observed on mechanical characteristics of the materials produced. In concrete and mortars, the fineness had an impact on increase in water demand, which increased mixtures porosity; and organic matter and heavy metals, in cement hydration. Recent studies therefore proposed waste material pre-treatment as a favorable alternative. Increases in porosity also occurred in ceramic bricks, however, due to high organic matter content. Regarding waste immobilization, cementitious materials showed satisfactory performance; ceramic bricks, on the other hand, obtained some results outside the normative limits. Therefore, it is necessary to expand discussions regarding the pre-treatment carried out on textile sludge, as well as its impacts on mechanical and environmental performance. disposal perspective preparation mortars bricks general produced demand metals hydration pretreatment pre however content hand limits Therefore

Resumo Olodo têxtil é um resíduo do tratamento do efluente das lavanderias têxteis e sua incorporação em materiais alternativos tem sido proposta como possibilidade para sua destinação. Foi realizada uma busca sistemática na literatura nesta perspectiva, visando observar as concentrações de material residual e seu preparo, as matrizes utilizadas, o desempenho tecnológico e imobilização do resíduo têxtil. As matrizes empregadas foram argamassas, concretos e tijolos cerâmicos, sendo observados, de maneira geral, efeitos deletérios nas características mecânicas dos materiais produzidos. Em concretos e argamassas, a finura impactou no aumento da demanda de água, o que elevou a porosidade das misturas; e a matéria orgânica e metais pesados, na hidratação do cimento. Estudos recentes propuseram, então, o pré-tratamento do material residual como uma alternativa favorável. Incrementos na porosidade também ocorreram nos tijolos cerâmicos, porém, devido ao elevado teor de matéria orgânica. Quanto a imobilização do resíduo, os materiais cimentícios apresentaram desempenho satisfatório; já os tijolos cerâmicos, obtiveram alguns resultados fora dos limites normativos. Portanto, é necessário ampliar as discussões quanto ao pré-tratamento realizado no lodo têxtil, bem como seus impactos no desempenho mecânico e ambiental. destinação perspectiva preparo utilizadas argamassas cerâmicos observados geral produzidos água misturas pesados cimento propuseram então prétratamento pré favorável porém satisfatório normativos Portanto ambiental

Abstract This study performed LSV simulation of two-step irreversible electron oxidation with the intermediate (E↓E), which was immobilized on the electrode surface. The response exhibited either one or two peaks, depending on the intermediate stability. The first electron transfer depended on the reactant diffusion, while the second one was a function of the accumulated intermediate. For this reason, the second Ip was higher than the first one, and the single peak split into two peaks, under the influence of an increased SR. Thermodynamic and kinetic parameters influence on the two components of the response were analyzed.

The study evaluated the solvent-free oxidation of 1-hexene utilizing supported ruthenium catalysts and a small amount of terbutyl hydroperoxide (TBHP) as a radical initiator. The characteristics of the supported catalysts were characterized using transmission electron microscopy (TEM) and N2 adsorption-desorption isotherms. The results of the study revealed that 1% Ru/TiO2 had favorable catalytic performance when subjected to environmentally friendly reaction conditions. This behavior was thought to be a result of Ru spreading and loading on the TiO2. To obtain optimal reaction parameters, the catalyst manufacturing process, temperature, reaction time, type of support, and activating amount were tuned. Compared to catalysts generated using wet-impregnation and precipitation techniques, those produced using sol-immobilization have greater activity.

Abstract Brazil is considered a world leader in paper production. It is estimated that the sector contributes 46.5% of the national gross domestic product, and its effluents have high concentrations of organic matter and recalcitrant compounds which can cause coloration and ecotoxicity, generating impact if not properly treated. A potential strategy for the treatment of this wastewater is bioaugmentation with native bacteria isolated from the industrial sludge and effluent, which, due to their potential metabolism adapted to adverse environmental conditions, may favor the removal of specific compounds. When associated with immobilization techniques, the inoculum can develop as a biofilm adhered to a support medium, which provides surfaces for adhesion, growth and survival of bacteria. We therefore investigated the treatment of Kraft pulp effluent by bioaugmentation with the autochthonous bacterium Advenella kashmirensis both immobilized in a spongy support medium - Aqua Porous Gel (APG) - and in free-swimming (planktonic) form, denominated Phase I and II, respectively. The investigation was performed in a bench-scale aerated lagoon system with untreated industrial effluent. The effect of the use of bacteria in bioaugmentation was assessed by the removal parameters of Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5), Color, Total Phenolic Compounds (TPC) and Lignin Compounds (LC). The results indicate that both Phases I and II were efficient for the treatment of COD, BOD5 and color parameters. However, the biofilm form provided better stability to the biological system in the treatment of the Kraft pulp effluent. production 465 46 5 46.5 product ecotoxicity treated conditions techniques adhesion APG (APG freeswimming free swimming planktonic (planktonic respectively benchscale bench scale COD , (COD) BOD5, BOD (BOD5) Color TPC (TPC LC.

Resumo O Brasil é considerado referência mundial na produção de papel, se estima que o setor contribui com 46,5% do produto interno bruto nacional, configurando uma manufatura extensiva cujos efluentes possuem concentrações elevadas de matéria orgânica e compostos recalcitrantes, que podem introduzir cor e ecotoxicidade, gerando impacto caso não se proceda o adequado tratamento do mesmo. Uma estratégia potencial para o tratamento desta água resíduária é a bioaumentação com bactérias nativas isoladas do lodo e efluente da indústria, estas devido ao potencial metabolismo adaptado às condições adversas do ambiente, podem favorecer a remoção de compostos específicos. Quando associada a técnicas de imobilização, o inóculo pode se desenvolver como biofilme aderido a um meio suporte, que proporciona superfícies para adesão, crescimento e sobrevivência das bactérias.

This work explores the possibility of using corn cob powder as a carrier for immobilization by physical adsorption of lipase from Rhizopus oryzae used in acidolysis reaction of grape seed oil with capric acid (C10) to synthesize dietary triglycerides (TAGs) formed from medium-long-medium chain (MLM) fatty acids in a fixed bed reactor. First, enzymatic loading was investigated to improve hydrolytic activity and the immobilized biocatalyst was characterized in terms of biochemical parameters and thermal stability. An enzyme load of 30 mg mL-1 was quite adequate, as about 90% of the immobilization yield was achieved. The central composite rotatable design (CCRD) experimental design revealed that, for the immobilized enzyme, the optimal hydrolytic activity was obtained at pH 7.75 and 41 °C. Stirred tank reactions were optimized in CCRD statistical analysis revealing the most desirable conditions for molar ratio of 1:9.36 (oil:acid), 45 °C and 15% biocatalyst, obtaining a maximum ID value of 86.93 ± 2.25%. In a fixed bed reactor, the synthesis showed an average ID of 51.13 ± 0.77, demonstrating the potential of this configuration. It is concluded that corn cob powder as an immobilization carrier is a promising alternative for the enzymatic synthesis of MLM triacylglycerols.

In recent years, various methods for surface functionalization of magnetite nanoparticles with emerging modifications have been explored and reported. Green nano-chemistry aims to synthesize nanomaterials using bio-based resources, providing new materials for biological and environmental applications. Surface modification of magnetite nanoparticles using phytochemicals extracted from plants is a fundamental principle of green synthesis routes. Agricultural waste from different crops, such as plantain pseudostem, is of particular interest as a renewable resource due to its abundant availability, low toxicity, and economic feasibility. In this study, the juice extracted from plantain pseudostem was utilized for the phytofunctionalization of magnetite nanoparticles. Characterization techniques including transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and fourier-transform infrared spectroscopy (FTIR) confirmed the nanometric dimensions of the composite (size range of 12.6 ± 3.17 nm) and established its organic-inorganic nature. The superparamagnetic properties of the composite were also demonstrated. Moreover, the potential application of this nanohybrid in bioremediation for the immobilization of cadmium(II) and lead(II) showed promising results, highlighting its efficacy in managing water pollutants. years reported nanochemistry nano chemistry biobased bio based resources applications routes crops availability toxicity feasibility study TEM, TEM , (TEM) SEM, SEM (SEM) TGA, TGA (TGA) fouriertransform fourier transform FTIR (FTIR size 126 12 6 12. 317 3 17 3.1 nm organicinorganic organic inorganic nature demonstrated Moreover cadmiumII cadmium II cadmium(II leadII lead lead(II results pollutants (TEM (SEM (TGA 1 31 3.

In this work, some of the synthesis methods already reported for aluminum(III) hydroxide polymorphs with layered structure like gibbsite are revisited. Gibbsite was synthesized with high purity and yield by a simple route developed from modifications of a heating method proposed in the literature, making it possible to prepare gibbsite in regular glassware, avoiding the use of hydrothermal reactor and oven, as described in the literature. The proposed synthesis was conducted with a heating system under reflux conditions in a glass heating flask, using an oil bath, without the need for more sophisticated equipment. This is an accessible alternative method for crystalline gibbsite synthesis, with yield (76 wt.%). The obtained gibbsite was used as a precursor for the synthesis of a lithium/aluminum layered double hydroxide (LDH) from the intercalation method of Al(OH)3 in aqueous solution of lithium chloride. Gibbsite and the obtained LDH Li/Al were used for the immobilization of an anionic porphyrin with a loading on the order of 10-5 mol g-1 of solid, thus being alternative solid supports for catalytic species such as porphyrins. work aluminumIII aluminum III aluminum(III revisited literature glassware oven flask bath equipment 76 (7 wt.%. wt wt.% . wt.%) lithiumaluminum (LDH AlOH3 AlOH Al OH 3 Al(OH) chloride LiAl Li 105 10 5 10- g1 g 1 g- porphyrins 7 ( wt.

Photosynthetic microorganisms have been widely studied as an alternative technology for CO2 capture. Aiming to overcome some operational challenges in the application of these microorganisms for gas treatment on a large scale, the immobilization of microalgae in solid matrices emerges as an alternative to facilitate effective management of microalgae culture during harvesting process. In this work, different matrices for microalgae immobilization composed of silica/alginate were obtained varying silica precursors. The synthesized materials were characterized in terms of their specific surface area, cell viability, transparency and physical-chemical properties. Additionally, a new methodology was developed to evaluate the CO2 capture by microalgae using a pressurized system with natural gas mixture. Tests were carried out exploring the influence of some variables, such as headspace volume, cell concentration, stirring and pressure. Once the optimized parameters were established, the amount of CO2 captured by immobilized microalgae was investigated for 7 days by determining the CO2 relative concentrations using gas chromatography. The results of immobilized microalgae showed levels of CO2 removal of 41.4%. This work proved the potential application of the studied biomaterial for natural gas processing, making even more feasible the adoption of this technology for selective capture of CO2 on an industrial scale.

Abstract Large quantities of residual cooking oil are being increasingly generated in various sectors, as it is often improperly disposed of and causes serious environmental problems. A commonly used alternative is the use of lipases in enzymatic hydrolysis, since it is rather attractive to several sectors, in addition to allowing the use of products generated thereof, such as: free fatty acids, diacylglycerols, monoacylglycerols and free glycerol, moreover, it is capable of operating in mild temperature and pressure conditions. Therefore, the present study aimed to evaluate alternatives for the hydrolysis of residual frying oil by evaluating the efficiency of different types of supports and heating systems using free and immobilized forms of lipase from Burkholderia cepacia (BCL) and Porcine pancreas (PPL) as biocatalyst. Polyhydroxybutyrate (PHB), niobium oxide (Nb2O5) and chitosan (CHIT) were evaluated as support for immobilizing BCL and PPL lipases, and superior results were found regarding the hydrolytic activity of immobilization derivatives using PHB and Nb2O5. Among the heating systems under evaluation, the highest percentage of residual oil hydrolysis was found using the ultrasound system for both free and immobilized lipases, reaching 57.91% hydrolysis for lipases immobilized on Nb2O5 and 61.11% hydrolysis for the derivative immobilized on PHB. The operational stability of both biocatalysts was evaluated using similar half-life time values for both. Thus, it was observed that the ultrasound system was efficient in improving lipase performance in the hydrolysis of free fatty acids, once this unconventional heating system is quite promising for accelerating such enzymatic reactions. sectors problems thereof acids diacylglycerols glycerol moreover conditions Therefore (BCL (PPL biocatalyst PHB, , (PHB) NbO Nb O (Nb2O5 CHIT (CHIT evaluation 5791 57 91 57.91 Nb2O 6111 61 11 61.11 halflife half life Thus reactions (PHB (Nb2O 579 5 9 57.9 611 6 1 61.1 57. 61.

Lipases have been used in industrial processes as biocatalysts for transesterification reactions. The synergism between enzymes and magnetic properties may be reached by using magnetic nanoparticles (MNPs) as support to immobilize them in aggregate structures, denominated by magnetic crosslinked enzyme aggregates (MCLEA). One of the advantages of such supports is the possibility of using magnetic separation for enzyme recovery, reducing costs and allowing reuse in continuous systems. Here, porcine pancreatic lipase (PPL) was immobilized onto functionalized magnetite support (Fe3O4-APTS) with a protein binding efficiency of 78.84%. Physical and chemical properties of the nanoparticles and immobilized lipase were characterized by X-ray diffraction (XDR), transmission electron microscopy (TEM), infrared spectroscopy (FTIR), dynamic light scattering (DLS), zeta potential, vibrating sample magnetometer measurements (VSM), and 57Fe Mössbauer spectroscopy. The immobilized lipase additionally exhibited improved stability across wide pH and temperature ranges compared with free lipase. The immobilized derivate also attained good reusability, maintaining 61.37% of its initial activity after 6 reaction cycles. Through magnetic behavior and also because of its surface modification to crosslinking the enzyme, the MCLEA produced in this work has enhanced the biocatalytic activities of PPL. reactions MNPs (MNPs structures MCLEA. .

In this work, the support, cashew apple bagasse (CAB), was chemically modified with divinyl sulfone (DVS), and it was evaluated to immobilize Candida antarctica lipase A (CAL-A). The best activation conditions of CAB support were defined by an advanced experimental design using the Taguchi method, assessing five factors at four levels (concentration of DVS, ionic strength, pH, temperature, and time). The support and biocatalyst (CAB-DVS-CAL-A) were characterized by Fourier transform infrared spectroscopy (FTIR), elemental analysis, thermogravimetry (TGA), scanning microscopy (SEM), fluorescence spectroscopy (XRF) and electrophoresis. The optimal conditions to activate the support were DVS concentration of 1.4 mol L-1 (3 mL of DVS in 20 mL of reaction volume), a concentration of sodium bicarbonate buffer at 5 mmol L-1, pH 3.0 at 30 °C for 12 h. The immobilization on CAB-DVS promoted increased thermal stability at 70 °C and different pHs of CAL-A. Therefore, the selected conditions allowed for a catalyst with a catalytic activity of 6.8 U g-1 and more stable than the free enzyme (CAL-A). This demonstrates that pretreated and DVS-activated CAB is a promising support for enzyme immobilization. work CAB, , (CAB) (DVS) CALA. CALA CAL .

ABSTRACT Objective: This article aims to evaluate the evolution of radio-graphic parameters (radial tilt, volar tilt, and radial height) of distal radius fractures in patients indicated for conservative treatment at three different times: date of diagnosis, first outpatient visit within 2 weeks after closed reduction, and last outpatient visit. Methods: We included 84 patients seen at the emergency department of Hospital Municipal Odilon Behrens, with a diagnosis of distal radius fracture and an indication for conservative treatment. We considered only those patients who had serial radiographs taken at least three different times (n=69) in this analysis. Results: There was an improvement in radiographic parameters of volar tilt after closed reduction and immobilization, which was maintained until the last outpatient visit. Radial inclination and radial height showed increased values from the first to the second radiographic evaluation and both values had regression when comparing the second to the third (last) evaluation. Conclusion: Universal classification stable fractures tend to evolve well with conservative therapy.

Abstract Immobility hypercalcemia is a rare diagnosis of exclusion that requires thorough evaluation. We present a case of hospitalized patient in Hospital General de México who on day 90 of hospitalization started acute hypercalcemia, with a low response to hyperhydration. During the approach, other causes of hypercalcemia with normal to low parathormone and vitamin D were excluded. The increase in serum calcium levels was sudden from 8.89 mg/dL to 13.05 mg/dL in 48 hours, which supports the diagnosis. He was treated with hyperhydration with crystalloid solutions and zoledronic acid, normalizing 72 hours after administration.
