Multisectoral Approach on COVID-19 vaccination: a proposed solution on vaccine hesitancy.

Abstract: As COVID-19 cases rise in one of Southeast Asia's worst-hit nations, low public trust in vaccines will be a huge block in the government's vaccination program. In a recent survey in January 2021 which was conducted by Pulse Asia, nearly half of Filipinos said that they would not get vaccinated against COVID-19 due to safety concerns. A proposed solution would be a Multisectoral Approach (MSA). MSA refers to the deliberate collaboration among various stakeholder groups (e.g. government, civil society and private and religious sectors) and sectors (e.g. health, environment and economy) to achieve a policy outcome. By engaging multiple sectors, such as interfaith collaborations, governments can leverage knowledge, expertise, reach and resources, benefiting from their combined and varied strengths as they work toward the shared goal of building public trust on vaccines.

Alkoxyamine‐mediated “living” radical polymerization: MS investigation of the early stages of styrene polymerization initiated by cumyl‐TEISO

Abstract: A new series of 1,1,3,3-tetraethylisoindoline-2-oxyl (TEISO)-based alkoxyamines was prepared. The half-lives for thermal dissociation indicated that the most sterically congested cumyl-TEISO alkoxymine had the greatest potential as an initiator for the polymerization of monomers at lower temperatures. The polymerization of styrene at 110 °C gave a linear evolution of M n with conversion in the early stages. Further evidence for the living nature was given by the polydispersities of the polymers that remained low (M w /M n = 1.13-1.27) throughout the polymerization (up to 80% conversion). No polymer was formed for the styrene system in a reasonable time below 100 °C. High-performance liquid chromatographic/mass spectrometric investigations of the distribution of trapped oligomers containing one to nine monomer units formed at 60 °C revealed that the trapping of oligomeric cumyl-styryl radicals by TEISO is irreversible at this temperature. Methyl methacrylate polymerized with cumyl-TEISO at 60-70 °C, although the initial high rates of polymerization soon decreased to zero at low conversions (10-15%), and the high polydispersities (M w /M n = 1.42-1.73) indicated significant side reactions.

Effect of nickel loading on the activity of Ni/ZrO2 for methane steam reforming at low temperature

Abstract: The effect of Ni loading on the catalytic activity of Ni/ZrO2 catalyst for methane steam reforming was investigated. The sample containing 15 wt.% Ni exhibited the highest activity as well as stability at 600°C.
