Novel Antimicrobial Organic Thermal Stabilizer and Co-Stabilizer for Rigid PVC

Novel antimicrobial organic thermal stabilizer and co-stabilizer for rigid PVC.

Biologically active N-benzoyl-4-(N-maleimido)-phenylhydrazide (BMPH) was synthesized and its structure was confirmed by elemental analysis and various spectral tools. It was examined as a thermal stabilizer and co-stabilizer for rigid poly (vinyl chloride) at 180 °C in air. Blending BMPH with reference samples in different ratios greatly lengthens the thermal stability value and improves the ex...

Sulfamethazine copper(ii) complexes as antimicrobial thermal stabilizers and co-stabilizers for rigid PVC: spectroscopic, thermal, and DFT studies

[CuL2(OH2)]$1.5H2O (1), [CuL2(bpy)]$0.66H2O (2) and [CuLQ(OH2)]$H2O (3) (HL 1⁄4 sulfamethazine, bpy 1⁄4 2,20-bipyridine and HQ 1⁄4 8-hydroxyquinoline) complexes were prepared, characterized (elemental analysis, infrared spectroscopy, thermogravimetric analysis, ultraviolet-visible spectroscopy, magnetic and conductivity measurement), and tested for their antibacterial activity. Coordination of ...

Stabilizer Design for Industrial Co-generation Systems

Existing large industrial control systems often exhibit poor tracking and disturbance rejection capabilities due to a large number of decentralized control loops. To improve these, a stabilizer design procedure is proposed based on H∞ optimization. The procedure is simple to apply and requires only some of the closed-loop transfer functions. Application of the approach in the Syncrude utility p...

Stabilizing Effect of Organic Stabilizer (EDTA, 1,2 Propane diol, Benzoic Acid and Phenol) on the Thermal Degradation of Polyvinyl Chloride (PVC)

STABILIZER TOPOLOGY OF HOOPS

In this paper, we introduce the concepts of right, left and product stabilizers on hoops and study some properties and the relation between them.  And we try to find that how they can be equal and investigate that under what condition they can be filter, implicative filter, fantastic and positive implicative filter. Also, we prove that  right and product stabilizers are filters and if they are ...
