We present the first fast and facile microwave assisted synthesis of polyaniline (PANI) nanofibers ("MWA synthesis"). Under conventional synthesis (CS), the polymer was produced with 79.7% yield after 5 h at ambient temperature. However, under microwave irradiation, the nanofibers were produced with yield of 76.2% after only 5 min, i.e., with 78.8% after 20 min at ambient temperature. The FTIR and Raman spectra show the PANI structure in all samples either synthesized conventionally or in the microwave. SEM and TEM confirm the nanofibrillar morphology.

A novel pH-responsive full-bio-based surfactant (Ca-S) containing a dynamic covalent bond is synthesized using renewable cashew phenol, 5-chloro-2-furanaldehyde, and taurine. The structure of Ca-S is characterized by Fourier transform infrared spectroscopy (FTIR) and H nuclear magnetic resonance (NMR) analysis. Limonene containing oil-in-water (O/W) microemulsions are prepared on the basis of the Ca-S surfactant and are applied to the remediation of oil-contaminated soil under low-energy conditions at ambient temperature.

are ubiquitous algae and occasional pathogens of humans and animals. While rare, the infection is often fatal and treatment options are limited to antifungals with low efficiency. Here, using growth curve assays, we demonstrate that five pathogenic species of () were fully inhibited by 50-100 μg/mL of herbicide glyphosate, suggesting novel pathways that can be considered for anti-algal drug development.

This study aimed to fabricate edible films from tapioca (T) and potato (P) starch, assessing their physicochemical properties and biodegradation across different ratios (T100P0, T70P30, T50P50, and T30P70). The films underwent evaluation for moisture content, thickness, water vapor permeability, and color values. T100P0 and T30P70 formulations exhibited the highest film transparency at 43.

February 2025

Program of Medical Technology, Faculty of Allied Health Sciences, Chonburi, 20130 Thailand.

Unlabelled: The aim of this study was to utilize four rice pasta by-products (RPB), including white rice pasta, black jasmine rice pasta, red jasmine rice pasta and brown rice pasta, to ferment into four vinegars. The dynamic variations during fermentation and their quality were evaluated. During alcoholic fermentation, the saccharified substrates were fermented with for 12 days, resulting in an alcohol yield of approximately 10% (v/v) after 4 days of fermentation.

Introduction Climate change is a decisive factor affecting human health. While many epidemiological studies have investigated the acute impacts of ambient temperature on mortality and morbidity, the global burden of infectious gastroenteritis linked to temperature changes remains largely unexplored. Therefore, we aimed to examine the exposure-response associations between ambient temperature and infectious gastroenteritis incidence throughout Japan and quantify the temperature-related morbidity burden.
