Effect of Crystal Polymorphism on Elastic Modulus and Hardness of Poly(Butylene 2,6‐Naphthalate) (PBN)

Polymer Engineering &Science, EarlyView.
The research provides insight into the mechanical behavior of the high‐performance polyester Poly(Butylene 2,6‐Naphthalate) containing different crystal polymorphs, adjustable by the conditions of melt‐crystallization. ABSTRACT The modulus of elasticity and hardness of poly(butylene 2,6‐naphthalate) (PBN) were investigated at different length scales ...

Tailoring MXene Flake Morphology via Aerosol Jet Printing for Biological and Strain Sensor Applications

Small, EarlyView.
Aerosol Jet Printing (AJP), coupled with a novel in situ monitoring method, enabled the controlled fabrication of aligned and crumpled Ti3C2Tx MXenes for diverse applications. Demonstrated across multiple 2D materials, this scalable strategy stablishes flake morphology as a controllable design parameter for engineering application‐specific material ...

The Effect of Hole Width on Full Height Rectangular Opening Castellated Steel Beam with Diagonal Stiffener Concerning Its Flexural Capacity [PDF]

, 2019
The use of a diagonal stiffener in a full height rectangular opening castellated steel beam can prevent the failure mechanism of vierendeel. This results in the flexural capacity of the castellated beam higher than the original IWF profile.

All Gone to the Dogs: Peasant and Aristocratic Masculinities in a Late Medieval Swiss Revolt

Gender &History, EarlyView.
ABSTRACT This article examines chronicle accounts of the so‐called ‘Waldmann Affair’, a revolt within the territories of the city–state of Zurich in 1489 directed against its mayor, Hans Waldmann. The revolt was partly the consequence of failed economic and political reforms which put pressure on the countryside, but was provoked by the command issued ...

Behavior of Castellated Composite Beam-Columns Subjected to Monotonic and Cyclic Loadings [PDF]

, 2016
The combination of Castellated beam system with composite beam system by adding in-filled concrete between the flanges of steel beam is expected to increase the capacity to accommodate the force and can overcome the shortcomings found in the two systems.

Atlantic trade and the West African market economy: New evidence from cowry imports, 1650–1905

The Economic History Review, EarlyView.
Abstract Between the seventeenth and twentieth centuries, billions of cowries arrived in West Africa, leaving one of the few quantitative traces available for historians to measure the Atlantic trade's impact on the precolonial market economy. Yet, current estimates substantially underestimate the volume of cowry imports.
