Laser‐Assisted In Situ Fabrication of rGO/Bi2O3 Nanocomposites for Heavy Metal Sensing

open access: yesSmall, EarlyView.
Rapid CO2 laser irradiation drives the in situ formation of Bi2O3 nanoplatelets within reduced graphene oxide, yielding flexible, reproducible electrodes with excellent stripping voltammetric performance toward trace heavy metals. ABSTRACT In this work, we introduce a laser‐assisted approach to synthesize reduced graphene oxide/bismuth oxide (III) (rGO/

3D‐Printed Milli‐Fluidic Mixing‐Extrusion Platform for Continuous, High‐Throughput LNP Production

open access: yesSmall, EarlyView.
We report a continuous high‐throughput production of lipid nanoparticles (LNPs) by integrating a reusable 3D‐printed milli‐fluidic split‐and‐recombine mixer with inline membrane extrusion. The 3D architecture enables rapid early‐stage mixing, reducing clogging and fouling, while inline extrusion further refines the as‐formed LNPs, improving uniformity,

Advancements and Challenges in Second‐ and Third‐Generation Biofuels: A Comparative Analysis of Lignocellulosic and Algal Feedstocks

open access: yesSafety Science and Technology, EarlyView.
ABSTRACT Advanced biofuels derived from nonfood biomass are increasingly recognized as strategic components of low‐carbon energy systems, particularly for sectors where direct electrification remains difficult. Second‐generation biofuels from lignocellulosic residues and third‐generation biofuels from algal and aquatic biomass offer complementary ...

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.
