AI Article Synopsis
- The article surveys data on the morphology and ultrastructure of flagellates in the order Trichomonadida, focusing on the families Monocercomonadidae and Trichomonadidae.
- The evolution of these flagellates involves key changes such as the development of the undulating membrane and the strengthening of the cytoskeleton.
- Additional evolutionary trends noted include a reduction in the flagellar apparatus in Monocercomonadidae and an increase in the number of free flagella in both families.
Article Abstract
In the article the survey of data on morphology and ultrastructure of flagellates of the order Trichomonadida is given with special attention paid to Monocercomonadidae and Trichomonadidae. The evolution within these flagellates is considered as a series of changes leading to formation of undulating membrane and reinforcement of the cytoskeleton. In both families other two evolutionary tendencies may be also observed: reduction of the flagellar apparatus (in Monocercomonadidae) and enlargement of the number of free flagella (in both families).

The trade-off between the performances of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) presents a challenge in designing high-performance aqueous rechargeable zinc-air batteries (a-r-ZABs) due to sluggish kinetics and differing reaction requirements. Accurate control of the atomic and electronic structures is crucial for the rational design of efficient bifunctional oxygen electrocatalysts. Herein, we designed a Sn-Co/RuO trimetallic oxide utilizing dual-active sites and tin (Sn) regulation strategy by dispersing Co (for ORR) and auxiliary Sn into the near-surface and surface of RuO (for OER) to enhance both ORR and OER performances.

Solid additives have garnered significant attention due to their numerous advantages over liquid additives. This study explores the potential of the green-fluorescent conjugated polymer denoted Atums Green as a solid additive in green-solvent-based PBDB-TF-T1:BTP-4F-12 solar cells. Even tiny amounts of Atums Green doping significantly improve the device performance.

Article Synopsis
- Laser-structuring techniques, particularly Direct Laser Interference Patterning, can significantly enhance the performance of pure Ni electrodes in water electrolysis by optimizing their structure.
- A study revealed that the spatial distance between laser-structures is critical for improving electrode performance, resulting in an increase in the electrochemically active surface area by up to 12 times compared to nonstructured electrodes.
- Optimal structuring leads to lower onset potential and overpotential during the oxygen evolution reaction due to the superhydrophilic surface, which enhances bubble growth dynamics and minimizes electrode resistance.
