Designing Strong, Tough, Fire‐Retardant and Self‐Healing Elastomers with Phosphorus/Nitrogen‐ and Biphenyl‐Containing Segments

open access: yesAdvanced Materials, EarlyView.
By designing a P/N‐ and π–π interacting biphenyl‐containing diol as hard segments but side groups, a strong, tough, fire‐extinguishing and self‐healing elastomer is developed, demonstrating a break strain of ∼2500%, a toughness of 379 MJ/m3 and a tensile strength of 46 MPa, as well as a healing efficiency of 95% (tensile strength) and 99% (break strain)

Weaning age and source of energy influence beef cattle performance, carcass characteristics, and economics

open access: yes, 2011
Angus and Angus x Simmental calves (n=200) were randomly allotted to one of five dietary treatments at two locations: Early Wean Starch Diet (EWS), Early Wean Fiber Diet (EWF), Creep Fed Starch Diet (CFS), Creep Fed Fiber Diet (CFF), or Control (CON ...

A Dual‐Bioresponsive and Programmable Microneedle Matrix as a Bioinspired Coupler for Orchestrating Diabetic Bone Regeneration

open access: yesAdvanced Materials, EarlyView.
This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.

G74-166 Creep Feeding Beef Calves

open access: yes, 1974
Effects of creep feeding calves are covered here. Gross income of the cow/calf enterprise is partially dependent on weaning weight of the calves. Three possible non-genetic ways of increasing calf weaning weight are to increase milk production of the dam,

Creep feeding en ambientes semiáridos

open access: yes, 2020
La técnica del creep feeding es una estrategia de “desmadre progresivo” donde se suplementa al ternero mientras se encuentra todavía al pie de la madre, buscando compensar el desbalance que se produce entre la producción decreciente de leche de las vacas y el aumento de los requerimientos nutricionales de sus crías.

Flexible Implantable Silicon Carbide Multi‐Electrode Array (MEA) for Cell Multichannel Recording and Cell Ablation

open access: yesAdvanced Materials Technologies, EarlyView.
Flexible silicon carbide (SiC) microelectrode arrays enable high‐fidelity, multichannel cell extracellular recording and precise localized ablation. SiC has been extensively evaluated to persist long‐term in chronic physiological conditions while remaining robust, with excellent electrical and electrochemical stability.
