Advancing Biomass Valorization via Electrocatalytic Oxidation: Design Principles, Emerging Challenges, and Future Perspectives

open access: yesSusMat, EarlyView.
This review categorizes substrates for electrocatalytic biomass valorization by carbon chain length into C2–C3 alcohols, C5–C7 cyclic compounds, and Cn biopolymers. It identifies four universal catalyst design principles: optimizing intermediate adsorption, engineering synergistic multi‐type active sites, accelerating active‐site formation, and ...

Effect of Propylparaben on In Vitro Maturation of Porcine Oocytes and Embryo Development

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Parabens are synthetic chemicals that, due to their antibacterial and fungicidal effects, are widely used as preservatives in food, cosmetics, and personal care products, such as shampoos, hair conditioners, body creams, soaps, deodorants, makeup, wet wipes, lotions, female hygiene products, and vaginal lubricants. Several years ago, they were

Insulation–Vibration Dynamics Model and Experimental Investigation of Cable Gas‐Insulated Switchgear Terminations

open access: yesHigh Voltage, EarlyView.
ABSTRACT Numerous breakdowns in cable gas‐insulated switchgear (GIS) terminations stem from inadequate insulation and interfacial stresses. However, existing diagnostic techniques, such as partial discharge detection and microwave detection, are highly susceptible to electromagnetic interference, or their diagnostic signals are often attenuated by the ...

MIRACLE URBANIZATION: Spatial Production and Political Legitimation in the Sochi 2014 and Beijing 2022 Olympics

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract From desert ski resorts to subtropical Winter Games, there is a global proliferation of ‘mission‐impossible’ mega‐projects. The prevailing frameworks of city branding and urban entrepreneurism fail to explain the political logics behind these seemingly irrational projects.

Influence of Steady Temperature Field with Spray Lubrication Engaging-in/out on Shipping Helical Gear Tooth Surface

open access: yesJixie chuandong, 2017
The gearbox is widely used in ships,studying its gear temperature field to avoid gear scuffing failure has larger significance. The rising temperature field by friction on gear tooth surface are simulated through the in- depth analysis of spray ...

Tool Life in the Turning of Oil Country Tubular Goods Using Eco-Friendly Lubri-Cooling

open access: yesIEEE Access
The global demand for fossil fuels has driven the oil and gas industry over the past decades, justifying the need for exploration at increasingly greater ocean depths in harsh environments. Oil Country Tubular Goods (OCTG) pipes are used in the drilling,

Sustainable Development Goals Applied to the Maritime Transportation Sector: Setting Sail for the Future

open access: yesNatural Resources Forum, EarlyView.
ABSTRACT The 2030 Agenda for Sustainable Development aims to eradicate poverty, protect the environment, and promote prosperity through 17 Sustainable Development Goals (SDGs). Achieving these goals requires a multi‐sectoral approach. Maritime transportation, vital to the global economy, significantly contributes to several SDGs and plays a strategic ...

TRPM8 and TRPM2 ion channels determine sex differences in thermal preference in mice

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Too hot or too cold? How do we know? Animals seek a ‘comfort temperature’ in between ‘too hot’ (far left) and ‘too cold’ (far right). In mammals and birds, females (left) prefer warmer temperatures than males (right). We show here that in mice, the comfort temperature is determined by a balance of sensory input (black arrows ...

Ice‐Droplet and Damaged Elastomer Interfaces: A Closer Look at Contact and Morphology of Anti‐Icing Coatings Using Cryo‐FIB‐SEM

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 46, December 10, 2026.
Cryo‐FIB‐SEM is used to mill and image the interfaces of ice droplets frozen on PDMS coatings damaged by abrasion and cutting. Both high‐ and low‐real contact areas are revealed for the first time, with interpenetration dependent on the shape of asperities on the damaged surface.

Influence of Porous‐Layer Permeability and Thickness on Stability and Load‐Bearing Capacity of a Porous air Bearing

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The paper deals with the simulation of porous journal bearings by solving the Reynolds and Darcy equations in conjunction with the continuity equation. To find the solution, the solution domain is discretized using the finite volume method.
