Logarithmic Finite-Size Scaling of O(n) Systems Having Upper Critical Dimensionality

Since the establishment of the renormalization group theory, it has been known that systems of critical phenomena typically possess an upper critical dimension dc (dc=4 for the O(n) model), such that in spatial dimensions at or higher than the dc, the thermodynamic behavior is governed by critical exponents taking mean-field values.

Developing High-Quality CsPbBrI2 Perovskites with Low Energy Loss

Over the years, the efficiency of PSCs has increased at an unprecedented pace. However, many reports have revealed significant irreversible decomposition of the organic component under high humidity and high temperature conditions, implying the instability of organic-inorganic hybrid perovskite solar cell in real applications.

Chemists Propose a New Approach for the Greener Use of Calcium Carbide

Calcium acetylide was discovered more than 150 years ago. It is a yellowish-white, beige, or grey solid, a compound of calcium and carbon. Calcium acetylide is currently used to produce gaseous acetylene. In industry, it is widely used in the production of acetic acid and ethyl alcohol, as well as it can be used in the production of plastics, rubber, and rocket engines.

Research Shines Light on the Responses of Polymers to Mechanical Stress

These are all examples of man-made polymers - long chains of repeated molecular units that we call monomers. While polymers also exist in nature (think wool, silk, or even hair), the invention of synthetic polymers, the most famous of which is plastic, revolutionized the industry.
