H2TPP(CH3)2(X) where X = NO2 and CHO exhibited very high dipole moment values (5.76‐7.59 D) as compared to H2TPP (0.052 D) due to push‐pull effect. These push‐pull porphyrins exhibited lower HOMO‐LUMO gap as compared to MTPP(NO2) and MTPP. The redox tunability was achieved ...
A series of new beta-functionalized push-pull-structured porphyrin dyes were synthesized so as to investigate the effect of the p-conjugated spacer on the performance of dye-sensitized solar c...
The design of the molecular structure, the substituent effect, and modulation of the electronic and geometric parameters can be used in order to optimize and tune frequency emission and conversion efficiency. Examples of some of the best dyes reported to-date and organic design strategies employed ...
In order to study the effect of the electron-withdrawing part on photophysical and electrochemical properties of the push–pull system, [1,2,5]thiadiazolo[3,4-b]pyrazine (10a,b) and quinoxaline (11a,b) structural analogues were synthesized. In this case, 1,2,5-thiadiazole-3,4-diamine (3...
Piezoelectric transducers convert electrical energy into mechanical energy by using the reverse piezoelectric effect. They are widely used in ultrasonic processing, medical engineering, micro-robotics, aerospace, and nanometer-scale positioning systems due to their simplicity of fabrication, high energy output...
Background/Objectives: While deficits in executive attention and alerting systems in children with attention deficit hyperactivity disorder (ADHD) are well-documented, findings regarding orienting attention in ADHD have been inconsistent. The current stu
Finally, to obtain the corrected resistance of the wire, the influence of the frequency on the effective cross-section according to the skin effect will be considered. Knowing the electron decay equation in the conductor cross-section modelled in (8) [33] and assuming that the electrons are co...
of conjugating with either the donor or the attracting portion of the heterocyclic system, consistent with contributions from isatylidene resonance forms which induce the C-8 carbon atom to be charged either positively or negatively, thus allowing an opposite sense of the push–pull effect. C...
As an effect, the dynamic power losses caused by diode recovery time and transistor turn-on hard switching also become zero. This effectively refracts the characteristic of the dynamic power losses when it transitions from CCM to DCM. In summary, given the converter elements, we can expect ...
We also examine the effect of push treatment sources (conspecific, heterospecific, and NHVs) used alone or in combination. Specifically, we hypothesized that (1) the semiochemical push–pull treatment technique effectively reduces bark beetle populations and (2) the effectiveness of the semiochemical...
