Speed and Atmosphere Influences on Nanotribological Properties of NbSe2 [PDF]

, 2009
Nanotribological properties of NbSe2 are studied using an atomic friction force microscope. The friction force is measured as a function of normal load and scan speeds ranging from 10 nm s−1 to 40 μm s−1 under two atmospheres (air and argon).

Low‐Cost Friction‐Based Force‐Limiting Connection With Reduced Sensitivity to Machining Tolerances and Accelerated Repairability

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper presents a novel yet practical friction‐based structural component design for low‐damage earthquake‐resistant structures. The proposed connection design is based on a conventional slotted‐bolted configuration with the novelty being the use of loose steel washer plates to establish the friction‐sliding interface.

Beeswax: Food and beyond

Food Biomacromolecules, EarlyView.
Abstract Honeybees (Apis mellifera L.) are an important class of insects that are the most beneficial in terms of economy. Beeswax is the second most important bee products after honey. Its commercial importance is due to its antimicrobial, antioxidant, anti‐inflammatory and antiseptic as well as regenerative properties.
