TL;DR: The polymerization system exhibits high photostability under NIR light exposure and irradiation dependency as demonstrated by light on/off experiments and the chain-end fidelity of the polymers was confirmed by chain extension and block copolymerization experiments.
Abstract: NIR-sensitized photoinduced atom-transfer radical polymerization (ATRP) is possible by using ppm of CuII /tris(2-pyridylmethyl)amine (TPMA) as the catalyst, a polymethine as the photosensitizer, and α-bromophenylacetate as the alkyl halide initiator. Among the polymethines investigated with cationic, zwitterionic, or anionic structures, only the zwitterionic 2 exhibited sensitization activity under NIR light at room temperature resulting in the formation of polymers with controlled molecular weight characteristics and functionalities. The barbital group placed at the meso-position of 2 caused the activity in this photo-ATRP framework. The chain-end fidelity of the polymers was confirmed by chain extension and block copolymerization experiments. The polymerization system exhibits high photostability under NIR light exposure and irradiation dependency as demonstrated by light on/off experiments.

TL;DR: In this article, a synthetic strategy for the preparation of melt-processable shape-memory hydrogels with self-healing ability is presented, which consists of poly(acrylic acid) chains containing 20-50 mol % crystallizable n-octadecyl acrylate (C18A) segments together with surfactant micelles.
Abstract: We present here a synthetic strategy for the preparation of melt-processable shape-memory hydrogels with self-healing ability. The supramolecular hydrogel with a water content of 60–80 wt % consists of poly(acrylic acid) chains containing 20–50 mol % crystallizable n-octadecyl acrylate (C18A) segments together with surfactant micelles. The key of our approach to render the hydrogel melt-processable is the absence of chemical cross-links and the presence of surfactant micelles. At temperatures above the melting temperature Tm of the crystalline domains of alkyl side chains, the hydrogel liquefies due to the presence of surfactant micelles effective for solubilizing the hydrophobic C18A segments. At this stage, it can easily be shaped into any desired form by pouring into molds. Cooling below Tm and removing the surfactant from the gel network results in a hydrogel of any permanent shape with a particularly high compressive strength of 90 MPa and a Young’s modulus of 26 MPa. If the hydrogel was damaged on p...

TL;DR: In this article, a new design equation for predicting the shear strength of monotonically loaded exterior beam column joints is proposed, which considers the influence of beam longitudinal reinforcement ratio, which was not taken into account in previously suggested design equations.
