Spatially Controlled 3‐D Multiplexed Aptamer Patterning in Hydrogels

open access: yesAdvanced Materials Interfaces, EarlyView.
A hydrogel platform based on norbornene‐functionalized polyvinyl alcohol enables high‐resolution, 3‐D multiplexed patterning of DNA aptamers via two‐photon polymerization. Two distinct aptamers are covalently immobilized with single micron‐scale precision across the x, y, and z dimensions.

Watching more than the Discovery channel : export cycles and diversification in development [PDF]

open access: yes
This paper examines the export performance of 99 countries over 1995-2004 to understand the relative roles of export growth through"discovery"of new products and growth during post-discovery phases of the export product cycle -- acceleration and ...

Biomechanical Performance of Additively Manufactured Bone‐Mimicking Scaffolds with Graded Architectures

open access: yesAdvanced Materials Technologies, EarlyView.
Nozzle temperature of 180 °C suits well for supportless PLA stochastic scaffolds. The scaffolds exhibit higher strength and stiffness under sudden impact loading. Grading type shows significant influence on scaffold properties. Radial descending type performs best in both mechanical and permeability aspects. Graded stochastic scaffolds are suitable for

Lightweight and High‐Performance Ankle Braces Enabled by 3D Printed Metamaterial Liquid Crystal Polymer

open access: yesAdvanced Materials Technologies, EarlyView.
A flexible, lightweight ankle brace made from 3D‐printed liquid crystal polymer metamaterials offers targeted support without restricting movement. Programmable stiffness provides protection during risky motions. Biomechanical tests suggest performance comparable to commercial braces with reduced bulk, highlighting potential for broader orthotic ...

The Micro Dynamic of Exporting-Evidence from French Firms [PDF]

open access: yes
This paper describes the dynamics of rms' exports to dierent countries. Using a panel of almost 19,000 French exporters, we dene an export-relation as an observed positive export ow from a French rm to a destination. We establish the following facts: 1.

3D Printing of Highly Porous Polypropylene Separators for Lithium‐Ion Batteries Using Fused Deposition Modeling and Thermally Induced Phase Separation

open access: yesAdvanced Materials Technologies, EarlyView.
This study demonstrates the 3D printing of custom‐shaped battery separators using a polypropylene/paraffin wax composite filament. A post‐processing step creates porous structures by removing wax. The printed porous separators show promising mechanical and electrochemical performance, offering a pathway toward conformable battery designs.

Impact of WTO on Potato Export from India [PDF]

open access: yes
Attempts are being made to export potatoes from India since 1970s but the quantities exported have been negligible and variable in spite of the fact that Indian potatoes are technically excellent and moderately export competitive. With the liberalization
