Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators

open access: yesAdvanced Materials Technologies, Volume 11, Issue 20, 21 October 2026.
Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.

Electrochemical Detection of Perfluorooctanoic Acid by a Zn–Terpyridine and Nafion‐Modified Glassy Carbon Electrode

open access: yesChemPlusChem, Volume 91, Issue 10, October 2026.
PFOA can substitute acetate ligands in zinc terpyridine complexes to elicit spectroscopic changes. This phenomenon in solution is exploited for electrochemical sensing using discontinuous Nafion overlayer as a preconcentrating membrane to provide detection limits of 0.407 pM and a linear range of 0.5–10 pM.

Factors affecting diffusion of atmospheric fluorocarbons into unsaturated porous materials

open access: yes, 1981
Atmospheric buildup of two fluorocarbon gases, CC1₃F (F-11) and CC1₂F₂ (F-12), during the past forty years has been documented by previous workers. The present study involved measurements of F-11 and F-12 concentrations in soil air within unconsolidated ...

Comparative Evaluation of HFC‐134a Decompositions Over Metal‐Impregnated γ‐Al2O3 Catalysts (M/γ‐Al2O3) (M = Mg, Ni, Co, Zn, Cu)

open access: yesAdvanced Energy & Sustainability Research
Al2O3, widely used in the catalytic decomposition of fluorocarbons, is known to be rapidly deactivated owing to its transformation to AlF3. Accordingly, in this study, metal‐impregnated γ‐Al2O3 catalysts (M/γ‐Al2O3) were synthesized and their long‐term ...

Architecting nano‐Al/HMX/CuO energetic micro‐units unlocks superior interface and highly efficient combustion

open access: yesInfoMat, Volume 8, Issue 10, October 2026.
Improving the dispersion of nano‐aluminum is of great importance in explosives and propellants. The spherical Al/HMX/CuO energetic micro‐units were prepared using microchannel technology, which significantly improved the uniformity and dispersion of nano‐Al. It also enhanced the mass and heat transfer efficiency between the fuel and oxidizer components,

Predictive Amphiphile Design Enables Control of Self‐Assembled Nanoparticle‐Cell Membrane Interactions

open access: yesSmall, Volume 22, Issue 60, 27 October 2026.
The interactions of self‐assembled nanocarriers with cell membranes are programmable through amphiphile design. We identify how head and tail chemistry govern distinct interaction mechanisms and introduce ΔGtransfer, a unified thermodynamic descriptor that predicts nanoparticle behaviour from simple molecular simulations.

Velocity of sound measurements in gaseous per-fluorocarbons and their custom mixtures

open access: yes, 2000
An inexpensive sonar instrument was prepared for measurements of sound velocity in two fluorocarbon vapors; per-fluoro-n-propane (C3F8), per-fluoro-n-butane (C4F10), and their custom mixtures.

Catalytic halodefluorination of aliphatic carbon–fluorine bonds

open access: yes, 2016
A variety of halosilanes, in conjunction with aluminum catalysts, convert fluorocarbons into higher halocarbons. Bromination and iodination of fluorocarbons are more effective than chlorination in terms of yield and activity.

Preparation of Hydrophilic Polysilsesquioxanes and Their Applications as Water Separation and Antifogging Coating Materials

open access: yesThe Chemical Record, Volume 26, Issue 10, October 2026.
Hydrophilic substituents were introduced onto the silicon atoms of random polysilsesquioxanes (PSQs) to improve water permeability and absorptivity for exploring the applications of PSQ materials as heat‐ and chlorine‐resistant water desalination reverse osmosis (RO) membranes and scratch‐resistant antifogging coating materials.

The Price of Prosperity? A Historical Account of Regulating Industrial Pollution in the Netherlands

open access: yesRegulation &Governance, Volume 20, Issue 4, Page 1360-1376, October 2026.
ABSTRACT Regulatory governance and state‐corporate crime studies link persistent industrial pollution to long‐term regulatory–industry interactions, yet little is known about how these interactions evolve and become entrenched. This article examines two enduring cases of industrial pollution in the Netherlands—Hoogovens/Tata Steel and DuPont de Nemours/
