Evaluate the quality of finishing and degree of contamination before and after handling and surface treatment of titanium (Ti) orthodontic mini-implants (OMIs). A scanning electron microscope (SEM) study on ninety-six titanium OMIs was done. Energy-Dispersive X-ray Analysis (EDX) identified the present particles on manufactured OMIs surfaces. Then, OMIs were manipulated with gauze (dry sterile, soaked in chlorhexidine) and gloves (latex, nitrile) to evaluate the contamination of these handling materials. Finally, OMIs underwent surface treatments and were placed in bone to observe the contaminants they released. Roughness (Ra) and wettability with contact angle parameter (CA) were measured on these treated OMIs. Machined OMIs presented surface irregularities and were contaminated with manufacturing-process particles (carbon, plastic Polyvinyl Chloride PVC, aluminum). Hand-manipulated OMIs were also contaminated by the handling materials. OMIs surface characteristics were as follows: acid-etched (Ra approximate to 1.3 mu m, CA approximate to 66 degrees), machined (Ra approximate to 0.3 mu m, CA approximate to 68 degrees), SB (Ra approximate to 3.3 mu m, CA approximate to 78 degrees), and SBAO (Ra approximate to 3.1 mu m, CA approximate to 92 degrees). Bone was contaminated by OMIs surface defects and extra particles. Manufactured OMIs have surface contaminants that increase with clinical handling. Surface treatments (SBAO, a combination of sandblasting and anodic oxidation) increase the roughness and contact angle, which play an important role in osseointegration. Surface-treated OMIs leave titanium particles in the bone during their insertion-removal. The use of a gauze soaked in chlorhexidine is recommended when handling OMIs. Further investigations would be interesting to study more variables and confirm the present results.

Nonlinear finite element analysis on the sealing performance of rubber packer for hydraulic fracturing

As the core component of a fracturing tool, a rubber packer plays a vital role during the well stimulation process. Its sealing performance significantly affects the fracturing effects. This study adopted a 3D multi-body contact nonlinear finite element analysis with the Mooney-Rivlin constitutive model to investigate the sealing performance of the hydrogenated nitrile butadiene rubber. The effects of key parameters such as the total thickness, sub-thickness, height, and rubber hardness on the sealing performance were systemically investigated. Numerical results indicated that maximum contact stress appeared around the rubber packer’s upper part because of the combined effect of friction and axial compression. Besides, the numerical results were validated with theoretical and experimental results, in which the error between theoretical and numerical results was less than 7%, and that between the numerical results and experimental results was approximately 17.7%. Under the conditions considered, key parameters of rubber packer were optimized as a total thickness of 20 mm, a sub-thickness of 13 mm, a height of 70 mm, and a hardness of 70 International Rubber Hardness Degrees, in terms of the maximum contact stress and deformation displacement. The proposed numerical approaches could accurately predict rubber packer’s deformation status, which consequently had technical guiding significance for the design of similar sealing components in various applications.

Study on the Synthesis of Castor Oil-Based Plasticizer and the Properties of Plasticized Nitrile Rubber

A series of new environment-friendly plasticizers was synthesized from castor oil and used to plasticize nitrile rubber (NBR). The test results showed that tensile strength, elongation at break, and tear strength of NBR vulcanizates plasticized by castor oil-based plasticizers were found to be better than that of dioctyl phthalate (DOP). The aging test taken demonstrated that the castor oil-based plasticizers could improve the hot air and oil aging resistance of NBR vulcanizates. The thermal stability test illustrated that castor oil-based plasticizers enhanced the thermal stability of NBR vulcanizates, and the initial decomposition temperatures (T-10%) were about 100 degrees C higher than that of DOP. In general, the studies manifested that EACO and EBCO can replace DOP to plasticize NBR and are used in fields that require high mechanical properties, aging resistance, and thermal stability. This study emphasizes the effects of sustainable, cost-effective, and high-efficiency plasticizers on NBR.

Synthesis of gamma-Spirolactams by Birch Reduction of Arenes

A convenient method for the synthesis of gamma-spirolactams in only three steps is described. Birch reduction of inexpensive and commercially available aromatic carboxylic acids in the presence of chloroacetonitrile affords nitriles in moderate to good yields. Suitable precursors are methyl-substituted benzoic acids, naphthoic, and anthroic acid. Subsequent catalytic hydrogenation proceeds smoothly with PtO2 or Raney Ni as catalysts and lactams are isolated in excellent yields and stereoselectivities. Thus, up to 3 new stereogenic centers can be constructed as sole diastereomers from achiral benzoic acids. Furthermore, it is possible to control the degree of saturation at different pressures, affording products with 0, 1, or 2 double bonds. Overall, more than 15 new gamma-spirolactams have been synthesized in analytically pure form.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 619-72-7. Safety of 4-Nitrobenzonitrile.

Insights into the mechanism and regioselectivity of the [3+2] cycloaddition reactions of cyclic nitrone to nitrile functions with a molecular electron density theory perspective

A molecular electron density theory study is presented for [3 + 2] cycloaddition (32CA) reactions of 2,2-dimethyl-1-pyrroline-1-oxide with the nitrile functions to analyse the mechanism and experimentally observed regioselectivity. Electron localisation function (ELF) study predicts zwitter-ionic character of the cyclic nitrone, allowing its participation in zw-type 32CA reactions associated with high energy barrier demanding overcome through appropriate electrophilic-nucleophilic interactions. Analysis of the CDFT indices predict the global electronic flux from the strong nucleophilic nitrone to the electrophilic nitrile functions. These 32CA reactions are endergonic with reactions Gibbs free energies between 5.5 and 39.2 kcal.mol(-1) in toluene. The ortho regiochemical pathway is preferred owing to the higher thermodynamic stability of the 2,3-dihydro-1,2,4-oxadiazole derivatives. The 32CA reaction of the nitrile function with carbomethoxy substituent is more facile relative to that with the phenyl substituent. Bonding evolution theory study predicts one-step mechanism with early TSs for the ortho pathway, while a one-step-two-stage mechanism is predicted for the meta reaction path, in conformity with the ELF and AIM topological studies at the TSs.

Detection of CH3C3N in Titan’s Atmosphere

Titan harbors a dense, organic-rich atmosphere primarily composed of N-2 and CH4, with lesser amounts of hydrocarbons and nitrogen-bearing species. As a result of high-sensitivity observations by the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 6 (similar to 230-272 GHz), we obtained the first spectroscopic detection of CH3C3N (methylcyanoacetylene or cyanopropyne) in Titan’s atmosphere through the observation of seven transitions in the J = 64 -> 63 and J = 62 -> 61 rotational bands. The presence of CH3C3N on Titan was suggested by the Cassini Ion and Neutral Mass Spectrometer detection of its protonated form: C4H3NH+, but the atmospheric abundance of the associated (deprotonated) neutral product is not well constrained due to the lack of appropriate laboratory reaction data. Here, we derive the column density of CH3C3N to be (3.8-5.7).x.10(12) cm(-2) based on radiative transfer models sensitive to altitudes above 400 km Titan’s middle atmosphere. When compared with laboratory and photochemical model results, the detection of methylcyanoacetylene provides important constraints for the determination of the associated production pathways (such as those involving CN, CCN, and hydrocarbons), and reaction rate coefficients. These results also further demonstrate the importance of ALMA and (sub)millimeter spectroscopy for future investigations of Titan’s organic inventory and atmospheric chemistry, as CH3C3N marks the heaviest polar molecule detected spectroscopically in Titan’s atmosphere to date.

Direct Catalytic Asymmetric Addition of alpha-Fluoronitriles to Aldehydes

A fluorine-containing tetrasubstituted stereogenic center is a highly valued structural feature in medicinal chemistry. Herein, we describe the direct coupling of racemic alpha-fluoronitriles and aldehydes promoted by a chiral Cu-I/Barton’s base catalytic system, delivering alpha-tetrasubstituted alpha-fluoro-beta-hydroxynitriles with satisfactory stereoselection. The stereochemical course was positively biased by the combined use of asymmetrical achiral thiourea as a supplementary ligand for Cu-I, which significantly enhanced the stereoselectivity. Both aromatic and aliphatic aldehydes were implemented to provide densely and stereoselectively functionalized chiral building blocks with aliphatic and aromatic tails.
