Cryogenics

Top Research Topics at Cryogenics?

The journal aims to foster the development of research in Superconductivity, Thermodynamics, Condensed matter physics, Cryogenics and Mechanics. The research on Superconductivity featured in Cryogenics combines topics in other fields like Composite material, Magnet and Nuclear magnetic resonance. As a part of the journal, discussions in Composite material involve topics like Thermal conductivity, Epoxy and Composite number.

Many of the studies tackled connect Nuclear magnetic resonance with a similar field of study like Electromagnetic coil. It features Thermodynamics research that overlaps with concepts in Helium. The research on Condensed matter physics featured in Cryogenics combines topics in other fields like Field (physics), Magnetic field, Magnetization and Current (fluid).

While Cryogenics is the focus of it, it also provided insights into the studies of Optics, Nuclear engineering, Cryostat, Liquid helium and Cryocooler. It holds forums on Mechanics that merges themes from other disciplines such as Regenerative heat exchanger, Pulse tube refrigerator and Conductor. Heat transfer coefficient, Heat flux and Nucleate boiling studies are all carried out as a component of the study in Heat transfer presented.

The previous edition focused in particular on these issues:

Cryogenics mostly deals with topics like Mechanics, Nuclear engineering, Composite material, Superconductivity and Cryocooler. The studies in Nuclear engineering featured incorporate elements of Superconducting magnet, Helium, Heat exchanger, Cryostat and Gas compressor. The journal explores topics in Composite material which can be helpful for research in disciplines like Liquid nitrogen and Strain (chemistry).

The presentations focused mostly on Superconductivity in an attempt to further explore topics in Condensed matter physics. It focuses on Condensed matter physics but sometimes tackles the closely related disciplines such as

• Voltage, which have a strong connection to Magnetic field and Conductor,
• Electrical conductor together with Electromagnetic coil.. Cryocooler research presented in it encompasses a variety of subjects, including Pulse tube refrigerator, Cooling capacity, Aerospace engineering, Water cooling and Stirling engine.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 13.91% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 33.33% were posted by at least one author from the top 10 institutions publishing in the journal. Another 7.07% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 12.12% of all publications and 47.47% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

• Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
• Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
• Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
• Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
• Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
