Towards an understanding of Type Ia supernovae from a synthesis of theory and observations

, 2013
Motivated by the fact that calibrated light curves of Type Ia supernovae (SNe Ia) have become a major tool to determine the expansion history of the Universe, considerable attention has been given to, both, observations and models of these events over ...

Polyglycerol‐Based Lipids: A Next‐Generation Alternative to PEG in Lipid Nanoparticles for Advanced Drug Delivery Systems

Macromolecular Rapid Communications, EarlyView.
Linear polyglycerol is proposed as a PEG‐alternative in mRNA‐loaded lipid nanoparticles to limit activation of anti‐PEG antibodies and reduce immunogenicity. Resulting nanoparticles may provide similar gene delivery capabilities, while preventing binding of anti‐PEG antibodies compared to PEGylated counterparts.

Nano Delivery Strategy Opens Effective Avenues for the Treatment of Colorectal Cancer

Medicine Bulletin, EarlyView.
ABSTRACT Colorectal cancer (CRC) presents significant therapeutic challenges because of chemoresistance, systemic toxicity, and the complexity of the tumor microenvironment (TME). Nanodrug delivery systems (NDDS) have emerged as versatile platforms capable of overcoming these limitations by enhancing tumor accumulation, improving pharmacokinetics, and ...

A Question of Trust: Dynamics of the Perceived Uncertainty–Trust Dilemma With Artificial Intelligence in Strategy Process Initiation

Managerial and Decision Economics, EarlyView.
ABSTRACT Strategists who must identify issues in uncertain environments while being cognitively constrained can increasingly rely on artificial intelligence to manage uncertainty. The potential for AI to be incorporated into strategy processes has led to a debate about the evolving collaborative relationship between strategists and AI.

Ignition and combustion characteristics of micro/nano-Al and Al@Ni alloy powders at elevated pressures

Case Studies in Thermal Engineering
Nanosizing and alloying of aluminum (Al) promisingly improve ignition and combustion performance of Al-based propellants. To aim this, lased-induced ignition and combustion characteristics of micro/nano-Al and aluminum@nickel (Al@Ni) alloy powders at ...

Convective Heat Transfer Scaling of Ignition Delay and Burning Rate with Heat Flux and Stretch Rate in the Equivalent Low Stretch Apparatus [PDF]

, 2011
To better evaluate the buoyant contributions to the convective cooling (or heating) inherent in normal-gravity material flammability test methods, we derive a convective heat transfer correlation that can be used to account for the forced convective ...
