Photoelectron Spectroscopy in Molecular Physical Chemistry

Photoelectron spectroscopy has long been a powerful method in the toolbox of experimental physical chemistry and molecular physics. Recent improvements in coincidence methods, charged-particle imaging, and electron energy resolution have...

The Physical Chemistry and Chemical Physics (PCCP) Section of the International Journal of Molecular Sciences in Its Publications: The First 300 Thematic Articles in the First 3 Years

The Physical Chemistry and Chemical Physics Section (PCCP Section) is one of the youngest among the sections of the International Journal of Molecular Sciences (IJMS)—the year 2021 will only mark three years since its inception [...]

Bimolecular Chemistry in the Ultracold Regime

Advances in atomic, molecular, and optical physics techniques allowed the cooling of simple molecules down to the ultracold regime ([Formula: see text]1 mK) and opened opportunities to study chemical reactions with unprecedented levels of control. This review covers recent developments in studying bimolecular chemistry at ultralow temperatures. We begin with a brief overview of methods for producing, manipulating, and detecting ultracold molecules. We then survey experimental works that exploit the controllability of ultracold molecules to probe and modify their long-range interactions. Further combining the use of physical chemistry techniques such as mass spectrometry and ion imaging significantly improved the detection of ultracold reactions and enabled explorations of their dynamics in the short range. We discuss a series of studies on the reaction KRb + KRb → K2 + Rb2 initiated below 1 [Formula: see text]K, including the direct observation of a long-lived complex, the demonstration of product rotational state control via conserved nuclear spins, and a test of the statistical model using the complete quantum state distribution of the products. Expected final online publication date for the Annual Review of Physical Chemistry, Volume 73 is April 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

eScience Infrastructures in Physical Chemistry

As the volume of data associated with scientific research has exploded over recent years, the use of digital infrastructures to support this research and the data underpinning it has increased significantly. Physical chemists have been making use of eScience infrastructures since their conception, but in the last five years their usage has increased even more. While these infrastructures have not greatly affected the chemistry itself, they have in some cases had a significant impact on how the research is undertaken. The combination of the human effort of collaboration to create open source software tools and semantic resources, the increased availability of hardware for the laboratories, and the range of data management tools available has made the life of a physical chemist significantly easier. This review considers the different aspects of eScience infrastructures and explores how they have improved the way in which we can conduct physical chemistry research. Expected final online publication date for the Annual Review of Physical Chemistry, Volume 73 is April 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

SCARING INTEREST IN LEARNING CHEMISTRY BASED ON CAREER INTEREST THROUGH ECOLECTROCHEMISTRY: PRESENTING INCLUSIVE CHEMISTRY IN ONLINE CLASS

The online learning of organic chemistry series chemistry in class XII MIPA Catholic SMA Santu Petrus Pontianak in the first three months of the odd semester showed a decrease in interest in learning chemistry. This study was conducted to find chemistry lessons that match the career interests of students, especially the study topics in the physical chemistry learning series (voltaic cells and electrolytic cells). On the topic of voltaic cells, group projects are carried out by choosing their own types of assignments according to the interests and learning styles of students with activities of making chemical songs, simple practicum, limited webinars and advertisements for voltaic cell products. On the topic of electrolysis cells, a group project was carried out with the concept of combining economics/business into electrochemistry, called ecolectrochemistry. The voltaic cell project assessment uses five parameters: the accuracy of the voltaic cell concept, the relevance of the voltaic cell concept to the concept raised, creativity, fulfillment of task requirements, and collaboration. The ecolectrochemistry project assesses problem-solving skills using the IDEALS model, presentation assessment and assessment of creative and disciplined attitudes. The active and enthusiastic involvement of students is better than in the organic chemistry series. There is an increase in interest in learning chemistry from 27.38% to 65.48% and there is an increase in the average learning outcomes of the physical chemistry learning series compared to the organic chemistry learning series. These results indicate that learning designed according to students'.
