Light attenuation characteristics of glacially-fed lakes [PDF]

open access: yes, 2014
Transparency is a fundamental characteristic of aquatic ecosystems and is highly responsive to changes in climate and land use. The transparency of glacially-fed lakes may be a particularly sensitive sentinel characteristic of these changes.

Bioinspired Shape‐Memory Hook Fasteners With Programmable Interlocking and Silent Release

open access: yesAdvanced Engineering Materials, EarlyView.
Bioinspired hook fasteners made from epoxy shape‐memory polymers are shown to switch between strong, secure attachment and gentle, silent release when heated. By combining programmable geometry and material response, these adaptive fasteners outperform commercial systems in strength and noise control, enabling new solutions for robotics, medical ...

The influence of physical and chemical linkage on the properties of nanocomposites [PDF]

open access: yes, 2005
It has been shown by several groups that the mechanical and electrical behavior of composites changes quite substantially, and often beneficially, when the filler particle size is less than 100 nm in diameter.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

open access: yesAdvanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Relationships Among Atmospheric Suspended Particulates with Different Sizes: A Case Study of Chongqing City

open access: yesAtmosphere
The current study predicts that there would be scaling relationships among atmospheric suspended particulate materials (PMs) with different diameters. Through sampling the particulate materials concentration over different types of land use in municipal ...

Investigation into dustiness on Veisiejai-Viktarinas-Paliepiai gravelled road treated with calcium chloride

open access: yesMokslas: Lietuvos Ateitis, 2011
The main problem related to gravelled roads is their dustability during the warm season of the year. Bituminous emulsion and calcium chloride are among the most popular and widespread materials used to reduce dustiness in Lithuania.

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Instillation of Particulate Suspensions to the Lungs

open access: yesBio-Protocol, 2017
Inhaled fine particulates are thought to cause chronic pulmonary inflammation through the deposition of particulates into the lungs. To investigate the effect of fine particulates on the lungs, instillation of suspension of particulates into the lungs is
