Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

AN ANALYSIS OF THE EFFECTS OF FEED INGREDIENT PRICE RISK ON THE SELECTION OF MINIMUM COST BACKGROUNDING FEED RATIONS [PDF]

open access: yes
The traditional minimum cost feed ration linear programming model is expanded to permit risk management responses to price variability associated with feeding a particular ration across time.

Straw: Low-cost feed but not least cost

open access: yesCalifornia Agriculture, 1977
Whenever grain and hay prices are high, there is renewed interest in feeding cereal straws to growing cattle as a possible method of cutting costs. Feeding trials were conducted using cereal straws in rations formulated by a computer least-cost ration program.

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

Incorporating Environmentally Compliant Manure Nutrient Disposal Costs into Least-Cost Livestock Ration Formulation [PDF]

open access: yes
Livestock rations are formulated to minimize feed cost subject to nutritional requirements for a target performance level, which ignores the potentially substantial cost of disposing of nutrients fed in excess of nutritional requirements.

Influence of the intensity of feed costs on efficiency of dairy cattle breeding

open access: yesAgricultural and Resource Economics, 2018
The aim of this paper is to investigate and analyze the factors that have a positive impact on the stabilization of the development of dairy cattle breeding, in particular the influence of the intensity of feed costs on the efficiency of dairy farms. The

Egg prices, feed costs, and the decision to molt

open access: yesPoultry Science, 2000
On April 7, 1998, the United Poultry Concerns filed a petition with the Department of Health and Human Services of the Food and Drug Administration calling for the elimination of the practice of forced molting of laying hens in the US. In reaction to this petition, this study investigated the economic importance of forced molting as a short-term ...

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing

open access: yesAdvanced Functional Materials, EarlyView.
A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Mechanical Programming of PEGDA‐β‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

open access: yesAdvanced Functional Materials, EarlyView.
A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...
