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.

Ignition Time Delay In Swirling Supersonic Flow Combustion

, 2012
Supersonic hydrogen-air cylindrical mixing layer is numerically analyzed to investigate the effect of inlet swirl on ignition time delay in scramjets. Combustion is treated using detail chemical kinetics. One-equation turbulence model of Spalart and Allmaras is chosen to study the problem and advection upstream splitting method is used as computational

Characterization of Ultrafast Decomposition Dynamics in Nitrate Esters

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Ignition of energetic materials initiates chemical reactions on atomic length scales within femtoseconds, making these reactions difficult to investigate experimentally. The technique of femtosecond time‐resolved mass spectrometry (FTRMS) can capture molecular rearrangement and bond‐breaking events in isolated molecules with sub‐50 femtosecond

IGNITION DELAY TIME INVESTIGATION OF GTL FUEL BLENDS

, 2022
Ignition delay is a vital combustion characteristic of any fuel that directly affects the development of internal combustion engines (ICEs) and exhaust emissions, especially in diesel engines. Considering the global interest in alternative fuels, GTL (Gas to Liquid) can be considered one of the promising new alternative fuels, especially for ...

Hydroxyl‐Terminated Polybutadiene‐Based Molding Powders as an Alternative Route for Manufacturing Pressed Polymer‐Bonded Explosives

Propellants, Explosives, Pyrotechnics, EarlyView.
This study presents an alternative method to manufacture polymer‐bonded explosives by partially curing an HTPB‐based molding powder prior to compaction. The study shows that the length of partial cure time before compaction directly influenced the geometric fidelity, homogeneity, compressive strength, density, and internal microstructure.

Tourism Labor Market and the Attainment of the 2030 Agenda for Sustainable Development Goals: Pending Challenges, Ongoing Opportunities and More Responsible and Inclusive Scientific Research for the Advancement of the Tourism Industry

Sustainable Development, EarlyView.
ABSTRACT Concerning human resources, research in the tourism sector has traditionally focused on a personnel‐managerial perspective rather than a labor market‐condition analysis per se, limiting the examination of its unique working ecosystem and distinct socioeconomic particularities. This has evidenced an apparent thematic research gap in the tourism
