Mesoporous Silica Nanoparticles in Biomedicine: Advances and Prospects

open access: yesAdvanced Materials, EarlyView.
Mesoporous silica nanoparticles offer unique properties like high surface area, tunable pores, and functionalization. They excel in drug delivery, tissue engineering, and stimuli‐responsive therapies, enabling targeted and controlled treatments. With roles in cancer therapy and diagnostics, their clinical translation requires addressing challenges in ...

Spin‐Crossover Confinement in Mesoporous Matrices Enables Tunable Porosity for Molecular Sensing

open access: yesAdvanced Materials Interfaces, EarlyView.
The integration of hierarchically organized porous frameworks with spin‐crossover nanodomains enables cooperative interactions across multiple length scales. This hybrid design merges dynamic molecular switching with tunable porosity, yielding materials whose structural and functional responses are actively modulated by confinement and guest uptake ...

Body Temperature Differences Between Green And Brown Grasshoppers Do Not Result From Thermal Physiology or Thermal Preferences

open access: yesEcology and Evolution
Colour polymorphisms correspond to the co‐occurrence of several distinct colour morphs that vary in hue and/or brightness, independently of sex, age or any other state‐dependent modifiers.

Microsatellite loci among Alaskan rabies hosts: Arctic and red fox [PDF]

open access: yes, 2012
Little is known about the population dynamics between Arctic and red foxes in Alaska and consequences for rabies ecology. Both species carry different variants of rabies and inhabit different environments.

Anti‐Slip Material‐Based Strategies and Approaches

open access: yesAdvanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Amblyomma tapirellum  (Acari: Ixodidae) collected from tropical forest canopy [v2; ref status: indexed, http://f1000r.es/2uy]

open access: yesF1000Research, 2014
Free-ranging ticks are widely known to be restricted to the ground level of vegetation. Here, we document the capture of the tick species Amblyomma tapirellum in light traps placed in the forest canopy of Barro Colorado Island, central Panama. A total of

Niche Breadth: Causes and Consequences for Ecology, Evolution, and Conservation

open access: yesThe Quarterly review of biology, 2020
Niche breadth is a unifying concept spanning diverse aspects of ecology, evolution, and conservation biology. Niche breadth usually refers to the diversity of resources used or environments tolerated by an individual, population, species, or clade.

Product Innovation and Population Dynamics in the German Insurance Market [PDF]

open access: yes
Empirical research in organizational ecology has mainly focused on analyzing founding and mortality rates using life history data of the organizations. We try to extend this approach in our study in a number of ways. In contrast to most empirical studies

Population status and habitat preferences of critically endangered Dipterocarpus littoralis in West Nusakambangan, Indonesia [PDF]

open access: yes, 2015
The conservation of the endemic tree species Dipterocarpus littoralis (Bl.) Kurz. is hampered by the paucity of information on its population biology and ecology. Consequently, a targeted survey was carried out in the West Nusakambangan Nature Reserve to
