Enhanced thermal conductivity of carboxyl nitrile butadiene rubber composites with low-cost poly(catechol/polyamine) modified Al2O3 via biomimetic method

With the miniaturization, integration, and functionalization of the electronic components, heat dissipation in the electronic devices has become a challenging issue. Owing to high polarity, carboxyl nitrile butadiene rubber (XNBR) is usually employed as a dielectric material in the electronic devices. However, low thermal conductivity of XNBR hardly satisfies the increasingly stricter demands for heat dissipation. Herein, we used low-cost poly (catechol/polyamine) (PCPA) to modify Al2O3 nanoparticles via biomimetic method for enhancing the interfacial interaction between the Al2O3 filler and XNBR. The ortho-polyphenols in catechol were oxidized into orthoquinone groups in the alkaline solution. Then, the ortho-quinone groups formed a cross-linked structure to obtain PCPA via the Michael addition or Schiff base reaction with amine. The process decreased the interfacial thermal resistance and phonon scattering, resulting in an enhanced thermal conductivity. When the Al2O3-PCPA nanoparticles content was 30 vol%, the thermal conductivity of XNBR based composites reached up to 0.51 W/ mK, which was 3.19 times that of pure XNBR (0.16 W/mK). The proposed method has potential applications in large scale production of thermally conductive composites in industries, such as electronic packaging materials and thermal management materials.

Machine learning-based prediction of enzyme substrate scope: Application to bacterial nitrilases

Predicting the range of substrates accepted by an enzyme from its amino acid sequence is challenging. Although sequence- and structure-based annotation approaches are often accurate for predicting broad categories of substrate specificity, they generally cannot predict which specific molecules will be accepted as substrates for a given enzyme, particularly within a class of closely related molecules. Combining targeted experimental activity data with structural modeling, ligand docking, and physicochemical properties of proteins and ligands with various machine learning models provides complementary information that can lead to accurate predictions of substrate scope for related enzymes. Here we describe such an approach that can predict the substrate scope of bacterial nitrilases, which catalyze the hydrolysis of nitrile compounds to the corresponding carboxylic acids and ammonia. Each of the four machine learning models (logistic regression, random forest, gradient-boosted decision trees, and support vector machines) performed similarly (average ROC = 0.9, average accuracy = similar to 82%) for predicting substrate scope for this dataset, although random forest offers some advantages. This approach is intended to be highly modular with respect to physicochemical property calculations and software used for structural modeling and docking.

Synthetic Exploration of alpha-Diazo gamma-Butyrolactams

DIazo transfer reaction onto -butyrolactams (activated by -ethyloxalylation) gave rare -diazo -butyrolactams. Decomposition of the latter by Rh-2(OAc)(4) in the presence of alcohols and water gave products of O-H insertion of the respective metal-cabene species. Silver triflate (1 mol-%) was found to convert the -butyrolactams investigated into 1,5-dihydro-2H-pyrrol-2-ones which represent versatile building blocks. Particular instability was noted for -diazo -butyrolactams bearing alkyl or o-substituted aryl substituents on the nitrogen atom. These were found to dimerize in solution or upon storage at room temperature to give fully conjugated bis-hydrazones along with the loss of a nitrogen molecule.
