Effect of experimental factors on nitrobenzaldehyde photoisomerization

Photocatalysis of 2,2′,3,4,4′,5′-hexachlorobiphenyl and its intermediates using various catalytical preparing methods

“…The quantum yields of 1,2,4,7,8-pentachlorodibenzofuran and 1,2,3,4,7,8-hexachlorodibenzofuran were 1.3 × 10 −2 and 6.9 × 10 −3 , respectively reported by Choudhry et al (1990) [33]. The quantum yields of these chlorinated xenobiotics were much lower than those of photosensitive chemicals such as nitrobenzaldehyde which was in the range of 0.45-1.46 reported by our previous investigation [34]. Dullin and Mill (1982) reported that sunlight actinometer such as nitrobenzaldehyde typically have the high value of quantum yield (φ > 0.5) [22].…”

Wave energy converter with mechanical motion rectifier, motion regulator, and energy storage element.

“…Multistage vibration energy harvester has a X-shaped structure and is designed to operate with MMR for large displacement input to ensure peak voltage of 0.15 V at 0.25 Hz frequency [35]. Lin et al [36] designed MMR based vibration energy harvester device for train suspension application to ensure better efficiency and power-to-weight ratio. Yang et al designed a coaxial MMR-based WEC with variable inertia to deliver maximum power of 2.15 W with an efficiency of 51.54% [15].…”

Ultraviolet–Visible Excitation of cis- and trans-p-Coumaric Acylated Delphinidins and Their Resulting Photochromic Characteristics

“…Earlier works by Yoshida et al and Hayashi et al showed that delphinidins acylated with p- coumaric acid can undergo photoisomerization in various buffers and solvents. Solvation is just one factor that contributes to the photoisomerization reaction, and other conditions such as concentration, excitation energy, and stereochemistry of reagent molecules may also play a role in its reactivity. − Experimental studies on ACN photoisomerization have focused mostly on solvation effects, which provides opportunities for further exploration of light energy and the reagent molecule in this reaction. For the findings of this research to be applicable to the food industry, sources of excitation that are easily acquirable and economical were chosen.…”
