Fundamentals of Heat Exchangers

, 2018
Heat exchangers are used to transfer heat between two sources. The term exchanger applies to allequipment used to transfer heat between two streams. However, the term is commonly used to equipment inwhich two process streams exchange heat with each other. This research paper explains the basics of heatexchangers, covering such topics as: classification;

Constructing Covalent Organic Polymers through Dative B─N Bonds: Synthesis, Single Crystal Structures, and Physical Properties

Advanced Functional Materials, EarlyView.
Dynamic linkages are highly attractive in preparing single crystals of covalent organic polymers (COPs). Here, single crystals of two COPs CityU‐15 and CityU‐16 based on reversible B─N bonds are constructed using tetra(4‐pyridyl)tetrathiafulvalene and tetra(4‐pyridyl)porphine as monomers.

Imbalanced Surface Charge Induced Phase Segregation in Mixed Halide Perovskites

Advanced Functional Materials, EarlyView.
The key factor determining the phase segregation in mixed halide perovskites (MHP) is the intrinsic imbalanced surface charges in the crystal lattice. MHP films with excellent crystallinity and surface morphology can suffer severe phase segregation.
