Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler

Advanced Materials, EarlyView.
An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...

Resolving Nanoscale Heterogeneities in Lead Halide Perovskites Through Low‐Dose Concurrent 4D‐STEM‐EDX Mapping

Advanced Materials, EarlyView.
Mixed‐cation lead mixed‐halide perovskites suffer from structural instabilities linked to nanoscale heterogeneity. To probe this non‐destructively, a low‐dose, concurrent 4D‐STEM and EDX methodology has been developed. Examining a (FA0.83Cs0.17)Pb(I0.8Br0.2)3 film revealed a complex mosaic of coexisting crystal structures. Crucially, local deficiencies

Polymeric Sorbents as Energy‐Efficient Alternative to Cryogenic Distillation for Light Hydrocarbon Purification

Advanced Materials, EarlyView.
The transition from cryogenic distillation to polymeric sorbents for light hydrocarbon purification is crucial for energy and environmental sustainability. The polymeric sorbents are engineered to separate gas mixtures based on their specific properties.

Sustained-release amorphous solid dispersions

Drug Delivery and Translational Research, 2018
The use of amorphous solid dispersions (ASD) to overcome poor drug solubility has gained interest in the pharmaceutical industry over the past decade. ASDs are challenging to formulate because they are thermodynamically unstable, and the dispersed drugs tend to recrystallize.

Assessing the performance of amorphous solid dispersions

Journal of Pharmaceutical Sciences, 2012
The characterization and performance of stable amorphous solid dispersion systems were evaluated in 40 research papers reporting active pharmaceutical ingredient (API) dissolution and bioavailability from various systems containing polymers. The results from these studies were broadly placed into three categories: amorphous dispersions that improved ...

Dissolution testing of amorphous solid dispersions

International Journal of Pharmaceutics, 2013
The main purpose of this study was to investigate the effect of different polymers, with varying physicochemical properties and molecular weight on the stability and dissolution of co-milled amorphous solid dispersions (ASDs) of piroxicam (PRX). The stability of amorphous PRX (aPRX) in ASDs was significantly improved by the polymers.

Characterization of amorphous solid dispersions

Journal of Pharmaceutical Investigation, 2017
The study of amorphous solid dispersions (ASDs) is currently one of the most exciting areas in pharmaceutics. Research has shown that ASDs offer unique advantages in improving the bioavailability of poorly water-soluble drugs over conventional delivery systems.

Multifractal and mechanical analysis of amorphous solid dispersions

International Journal of Pharmaceutics, 2017
The formulation of lipophilic and hydrophobic compounds is a challenge for the pharmaceutical industry and it requires the development of complex formulations. Our first aim was to investigate hot-melt extrudate microstructures by means of multifractal analysis using scanning electron microscopy imaging. Since the microstructure can affect solid dosage

Stability of Amorphous Solid Dispersion

2014
Amorphous solid dispersion (ASD) has attracted tremendous attention in pharmaceutical development due to its characteristic solubility enhancement, thus positively affecting oral bioavailability of a range of hydrophobic drugs. Nevertheless, being in a metastable state, ASD has the intrinsic tendency of spontaneously reverting to a more stable ...
