Integrated Multiband Smart Windows From UV to LWIR Based on Molecularly Engineered Thermochromic Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
A multiband smart window integrating a thermochromic poly (EEEA‐co‐NIPAM) hydrogel with functional layers, enabling dynamic VIS‐NIR solar modulation alongside UV shielding and low LWIR emissivity. The polymer network forms hydrogen‐bonding interactions, promoting chain collapse above a reduced lower critical solution temperature, and accelerating the ...

Thermal stability of modified telechelic polystyrenes [PDF]

open access: yes, 1993
peer reviewedThe thermal stability of telechelic polystyrenes bearing quaternary ammonium iodide or ammonium sulfonate end groups is presented. It appears that the ammonium iodide functions are stable below 200°C.

Thermal degradation of phosphonated polystyrenes. Part 1: Chain and condensation

open access: yes, 1984
Polystyrenes substituted with chloromethoxyphosphonated groups at chain ends undergo a condensation reaction at a relatively low temperature (ca. 200°C) prior to extensive degradation of the polymeric chain (280-430°C).

Elongational viscosity of LDPEs and polystyrenes using entrance loss data

open access: yes, 2008
For two low-density polyethylenes and two polystyrenes, axisymmetric and planar elongational viscosities are estimated using entrance loss data from capillary and slit rheometers, respectively.

A 3D‐Printed Model of Human Lactation

open access: yesAdvanced Healthcare Materials, EarlyView.
Breastfeeding supports infant and maternal health, yet in vitro models that mimic human lactation remain scarce. Here, light‐based 3D printing creates high‐resolution, alveoli‐inspired microwells that guide breast cells into polarized microtissues. The printed scaffolds embed slow‐release prolactin microcrystals to deliver hormonal cues, enabling human
