Pathogen avoidance by insect predators [PDF]

open access: yes, 2008
Insects can detect cues related to the risk of attack by their natural enemies. Pathogens are among the natural enemies of insects and entomopathogenic fungi attack a wide array of host species.

High‐Performance Air‐Stable Polymer Monolayer Transistors for Monolithic 3D CMOS logics

open access: yesAdvanced Materials, EarlyView.
A fibrillar polymer monolayer with a self‐confinement effect is demonstrated, in which aligned chains parallel the nanofiber axis. Employing a top‐gate CYTOP dielectric, this monolayer transistor achieves high mobility (7.12 cm2 V−1 s−1) and exceptional stability over 1260 days in air.

Should Grain Elevator Managers Adopt Integrated Pest Management? [PDF]

open access: yes
Insect infestation during storage and processing causes millions of dollars of wheat damage annually in the United States. Insect infestation reduces wheat storing processing profit as well as consumer confidence in wheat food products.

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms

open access: yesAdvanced Materials, EarlyView.
This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

Comparison of Two Different DNA Isolation Methods (Quick & Dirty vs. Commercial Kit) in Small Insects

open access: yesTurkish Journal of Agriculture: Food Science and Technology
The COI gene region is the most commonly employed method for species identification in insects, as in all animals. The importance of DNA isolation methods is increasing, and they are of great importance for identifying insects. Unlike other large animals,

Electrically Tunable Friction: From Sticky to Slippery with Ionic Hydrogels

open access: yesAdvanced Materials, EarlyView.
This work demonstrates electrically tunable friction “from sticky to slippery” using ionic hydrogels, achieving reversible more‐than‐fifty‐fold modulation without liquid lubricants. An electric field extracts a salt‐rich interfacial layer that dramatically reduces friction.

Mistletoe‐ and Mussel‐Inspired Fabrication of Hierarchically Structured Protein‐Cellulose Scaffolds From Biomolecular Condensates

open access: yesAdvanced Materials, EarlyView.
Merging materials processing tricks inspired by mussel and mistletoe fiber fabrication, solutions of cationic mussel byssus proteins were mixed with modified anionic nanocrystalline cellulose, producing distinctive core‐shell condensates. Simple processing of condensate suspensions using freeze‐drying produced hierarchically structured porous protein ...
