Full Science, Technology, Engineering, Arts and Mathematics Ahead: Leveraging Immersive Virtual Reality to Create Equitable and Transformative Learning Experiences

open access: yesFuture in Educational Research, EarlyView.
ABSTRACT Immersive virtual reality (IVR) is widely promoted as a means of enriching learning in science, technology, engineering, arts and mathematics (STEAM), yet evidence of its capacity to foster equitable classroom experiences for marginalised groups remains limited, particularly outside traditional STEM domains.

Does Palsa Thaw in Northern Finland Contribute to Remobilisation of Metals Accumulated in Peat Into Surface Waters?

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Ignition delay times of benzene and toluene with oxygen in argon mixtures [PDF]

open access: yes
The ignition delay times of benzene and toluene with oxygen diluted in argon were investigated over a wide range of conditions. For benzene the concentration ranges were 0.42 to 1.69 percent fuel and 3.78 to 20.3 percent oxygen. The temperature range was

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

open access: yesMacromolecular 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

open access: yesMedicine 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 ...
