Performance Comparison of the Vapor-Injection Cycle in Terms of Branching Points of the Injection Stream

open access: yes, 2012
The performance of the two types of vapor-injection (VI) cycles in a heat pump system is compared. The vapor-injection cycle using an internal heat exchanger (IHX) has a choice to select the branching point of the injection stream.

Polarity‐Reversible Photoresponse–Driven Autonomous Wavelength Discrimination in Quantum Dot–Tellurium Thin‐Film Photodetectors via Engineered Energy‐Band Alignment

open access: yesAdvanced Functional Materials, EarlyView.
A quantum dot–tellurium thin‐film photodetector autonomously discriminates visible and infrared wavelengths through polarity‐reversible photoresponses. Engineered carrier separation and gain modulation enable filter‐free multispectral sensing within a single‐device architecture.

3D Printing Innovations in Polymeric Porous and Patterned Architecture

open access: yesAdvanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Support for a reciprocal effects model of self-concept and academic achievement through a contrast of multidimensional and unidimensional approaches

open access: yes, 2006
There is a longstanding debate in the self-concept literature surrounding the causal ordering of self-concept and academic achievement. Some researchers have argued that self-esteem has no positive impact upon performance (Baumeister, Campbell, Krueger &

Spatiotemporal Drug Delivery via a Neonatal Spinal Cord ECM Hydrogel for Biomimetic Microenvironment Remodeling After Spinal Cord Injury

open access: yesAdvanced Functional Materials, EarlyView.
A biomimetic hydrogel derived from neonatal spinal cord ECM (DNSCM) delivers LAMB2 protein and ISP peptide to remodel the inhibitory injury microenvironment. The system sustains drug release, upregulates pro‐regenerative LAMB2, downregulates inhibitory CSPG, and promotes axonal regeneration.
