Res., 29, 217 2021 Patients at risk for hypertension with comorbidities such as diabetes and metabolic syndrome often require two or more antihypertensive drugs to lower blood pressure. Telmisartan and amlodipine are widely known drugs to treat hypertension. A solid dispersion containing a water-soluble polymer was prepared to make the absorption rate of telmisartan, a poorly soluble drug, similar to that of amlodipine, a soluble drug. Polyvinylpyrrolidone K30, polyethylene glycol 6000, and poloxamer 407 were used. The encapsulation of the solid dispersion was analyzed by differential scanning calorimetry, X-ray diffraction, and high-performance liquid chromatography. The reduced flow...

Res., 29, 252 2021 Two types of aluminum-exfoliated graphite nanoplatelet Al-xGnP hybrid powder were prepared, one is fully inserted exfoliated graphite nanoplatelet xGnP and the other is partially inserted xGnP in Al-flakes. TEM images of hybrid powder showed the partially and fully inserted xGnP in Al-flakes. The thermal conductivities of the epoxy composites increased monotonically with the filler content and the partially and fully inserted epoxy/Al-xGnP composites showed almost 2-3 times higher than those of epoxy/xGnP and epoxy/Alcomposites.

Res., 29, 267 2021 A flexible polyaniline-strontium PANI-Sr composite thin film has successfully been prepared as an efficiency material for ammonia gas sensing at low concentration via in situ chemical oxidative polymerization. The interaction between PANI matrix and strontium particles enhance the conductivity. Moreover, this improved character has been exploited to demonstrate the high selectivity, an excellent seneitivity towards the ammonia, a good reproducibility and a fast reponse/recovery time at room temperature.

Res., 29, 321 2021 A facile synthetic approach for imide-based porous porphyrin polymers POPs is disclosed. The polymer structures were characterized by various spectroscopic and microscopic techniques. The reported POPs showed good CO2 uptake capabilities and MnIII-POP was found to be an effective catalyst for the selective epoxidation ofstyrene.
