Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Cool Kitchen: Processing Starch and Eggshell Powder into Sustainable Coatings for Passive Daytime Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A food‐grade cooling composite made from starch and recycled eggshell powder offers a scalable, ultra‐low‐cost solution for passive daytime radiative cooling. Easily prepared using basic kitchen tools, this material empowers communities, even in areas with limited infrastructure, to stay cooler during worsening summer heat waves.

Electrical transport in

Journal of Physics: Condensed Matter, 1999
We report a systematic study of the effect of increasing oxygen deficiency on the electrical resistivity, tunnelling conductance and thermopower of . Stoichiometric behaves like a normal metal with a positive temperature coefficient of resistivity (TCR) and a negative thermopower which is proportional to temperature over the range 5 K-300 K.

Electrically Induced Carrier Transport

Nature, 1970
WHEN the transport of a solute across a membrane is augmented as a result of a reversible reaction with a carrier which shuttles between opposite faces of the membrane, the process is called facilitated transport. This phenomenon is of interest because it occurs in a wide variety of biological membranes1, and because it may have important practical ...

Electrical transport in a microdevice chain

Superlattices and Microstructures, 1987
A simple transport theory of a one-dimensional chain of small devices is presented. The chain is comprised of potential barriers connected by short conductors. Electrical transport through the barriers is described in terms of the quantum reflection and transmission coefficients.

Electric Transportation [Guest Editorial]

IEEE Power and Energy Magazine, 2011
Rising energy prices, concerns about climate change, and growing political implications in providing reliable access to petroleum has reignited the quest for electrified transportation around the globe. Considering the fact that over 77 million land vehicles were manufactured in 2010 alone, the transformation to an all-electric automotive industry, or ...

Road Transportation with Electric Vehicles

IFAC Proceedings Volumes, 1983
Road transportation with electric vehicles has gained more importance after the first oil crisis in 1973. This survey paper presents some assessments related to the impact of introducing electric vehicles on traffic, environment, energy. The perspectives and goals of the electric vehicle industry is briefly discussed.

Electrical-Transport Methods

1956
This section is intended to outline methods of analysis using the separation of substances resulting from their movement in an electric field. This includes the phenomena of electrophoresis (of colloids) and ionophoresis (of crystalloids). However, the more general title is used because additional phenomena may play a part in analytically useful ...
