Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Machine Learning‐Enhanced Modeling of Calcium Carbonate Nucleation in Porous Media Under Counter‐Diffusion Conditions

open access: yesWater Resources Research
A counter‐diffusion reactive transport experiment was conducted to study calcium carbonate (CaCO3) nucleation and growth in porous media, monitored in situ using synchrotron‐based techniques and modeled marrying the Classical and Non‐Classical Nucleation

Particle Size Distribution of Materials and Chemical Element Composition in Mixed Commercial Waste

open access: yesWaste
In processing mixed commercial waste (MCW), particle size distribution is as critical as material composition. Detailed knowledge of particle size distribution unlocks the recycling potential of specific material groups and facilitates the efficient ...

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

open access: yesAdvanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

A Roadmap to Reduce U.S. Food Waste By 20 Percent, Executive Summary 2016 [PDF]

open access: yes, 2016
The magnitude of the food waste problem is difficult to comprehend. The U.S. spends $218 billion a year -- 1.3% of GDP -- growing, processing, transporting, and disposing of food that is never eaten.

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Law Enforcement and Illegal Trafficking of Waste: Evidence from Italy [PDF]

open access: yes, 2015
The illegal trafficking of waste has become one of the fastest growing areas of crime and one of the most lucrative industries among organized criminal activities, which has infiltrated both the Italian urban and hazardous waste management cycle.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Study of a composting process in the green waste processing plant [PDF]

open access: yes, 2019
Composting of sewage sludge together with green waste such as grass, leaves, branches, etc. is carried out in Poland in a number of facilities. A common problem of all compost plant operators is the selection of the type of composting technology and its ...
