Cyclic Olefin Copolymers as Versatile Materials for Advanced Engineering Applications

open access: yesAdvanced Functional Materials, EarlyView.
Cyclic olefin copolymers (COCs) are presented as highly versatile materials combining tunable synthesis, excellent optical properties, and mechanical robustness. Their potential spans microfluidics, bioengineering, and advanced electronics, while emerging self‐healing and sustainable solutions highlight future opportunities.

Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

Optimal Tax Policies with Private-Public Clean-Up, Cross-Border Pollution and Capital Mobility [PDF]

open access: yes
This paper builds a model of a region with two non-identical countries, cross-border pollution and free movements of goods and capital within the region. Pollution reduces welfare and there is simultaneous private and public pollution abatement.

Attribution of pollution generation to local private and public demands in a small open economy: results from a SAM-based neo-classical linear attribution system for Scotland [PDF]

open access: yes, 2004
For the construction of environmental accounts, Input Output (IO) systems have a number of clear advantages. First IO is an internally consistency, rigorous accounting framework. Second, the characteristics of IO systems are well known. Third, IO systems

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis

open access: yesAdvanced Functional Materials, EarlyView.
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

Responses of Methanosarcina barkeri to acetate stress

open access: yesBiotechnology for Biofuels, 2019
Background Anaerobic digestion of easily degradable biowaste can lead to the accumulation of volatile fatty acids, which will cause environmental stress to the sensitive methanogens consequently. The metabolic characteristics of methanogens under acetate

Marine Pollution [PDF]

open access: yesScience, 1971
In the editorial, "Marine pollution" (8 January 1971, page 21), the value given for the concentration of mercury found in tuna (paragraph 2, line 10, 0.5 x 10-6 part per billion) is incorrect. The correct value is 500 parts per billion.
