This paper explores a possible design for a CMOS compatible, athermal, optical waveguide. The design explored is a slot waveguide with light guided in the low index material. A design paradigm is proposed which shows the relationship between cross-sectional parameters and their impact on both the effective index of refraction and the thermo-optic coefficient of the device. Two materials choices...

A series of multi-functional hydrogel systems have been designed and synthesized for potential brain implantation to realize controlled and sustained release of Nerve Growth Factor (NGF) for the treatment of Alzheimer’s disease (AD). The systems are three-dimensional crosslinked copolymers composed of a thermo-responsive unit, a hydrolytically degradable and hydrophobic unit, and an enzymatical...

Liquid transportation without employing a bulky power source, often observed in nature, has been an essential prerequisite for smart applications of microfluidic devices. In this report, a leaf-inspired micropump (LIM) which is composed of thermo-responsive stomata-inspired membrane (SIM) and mesophyll-inspired agarose cryogel (MAC) is proposed. The LIM provides a durable flow rate of 30 μl/h ·...

In article number 2100782, Shin-Hyun Kim and co-workers design thermo-responsive microcapsules with ultra-thin hydrogel membranes. The show molecular-size-selective transmembrane permeation due to the consistent mesh size of membrane. More importantly, cut-off threshold can be reversibly adjusted by temperature control. Therefore, provide molecule-selective encapsulation controlled release enca...

We report on novel type of responsive double hydrophilic block copolymer (DHBC)-based multifunctional chemosensors to Hg(2+) ions, pH, and temperatures and investigate the effects of thermo-induced micellization on the detection sensitivity. Well-defined DHBCs bearing rhodamine B-based Hg(2+)-reactive moieties (RhBHA) in the thermo-responsive block, poly(ethylene oxide)-b-poly(N-isopropylacryla...
