Behavior of Castellated Beams with and Without Stiffeners

International Journal of Innovative Research in Computer Science and Technology, 2020
Castellated beam applications for diverse buildings are quickly gaining popularity. This is a result of the section's enhanced depth without adding weight, excellent strength-to-weight ratio, low maintenance requirements, and low cost of painting. Increased vertical bending stiffness, ease of service provision, and appealing appearance are the main ...

Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

Advanced Materials, EarlyView.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

Revealing the Nanoscale Morphology Changes of Polymer Electrolyte Membrane Fuel Cell Catalyst Layers due to Conditioning

Advanced Science, EarlyView.
We apply ex situ and in situ scanning transmission X‐ray microscopy to reveal the structural degradation of polymer electrolyte membrane fuel cell catalyst layers due to conditioning and thermal heating of the catalyst coated membrane. We observe a redistribution of the ionomer and carbon‐black in the catalyst layer, as well as nanoscale membrane ...

Improving Behavior of Castellated Beam by Adding Spacer Plat and Steel Rings [PDF]

, 2018
Castellated steel beams are those members which are made from hot rolled steel I-section firstly by cutting the web in zigzag pattern and rejoining the two halves by welding together to form a hexagonal castellated beam such that the depth of section ...

A Strategic Approach to Improving Interfacial Interactions in TPU/POSS Composites via Ball Milling of POSS

Polymer Engineering &Science, EarlyView.
Ball‐milling promotes uniform POSS dispersion in the TPU matrix, markedly improving the mechanical performance of TPU‐POSS composites. ABSTRACT We synthesized TPU/POSS composites through a two‐step process involving the ball milling of POSS to reduce its particle size, followed by in situ polymerization of TPU to reinforce the material.
