Microwave heating of ceramic composites [PDF]

, 2000
The microwave heating of a ceramic composite is modelled and analysed. The composite consists of many small ceramic particles embedded in a ceramic cement.

Composite Material Recycling Technology—State-of-the-Art and Sustainable Development for the 2020s

Journal of Composites Science, 2020
Recently, significant events took place that added immensely to the sociotechnical pressure for developing sustainable composite recycling solutions, namely (1) a ban on composite landfilling in Germany in 2009, (2) the first major wave of composite wind

Maximum occupation number for composite boson states

, 2002
One of the major differences between fermions and bosons is that fermionic states have a maximum occupation number of one, whereas the occupation number for bosonic states is in principle unlimited.

Large N Expansion for Strongly-coupled Boson-Fermion Mixtures [PDF]

, 2010
We study a many-body mixture of an equal number of bosons and two-component fermions with a strong contact attraction. In this system bosons and fermions can be paired into composite fermions.

Influence of in vitro irrigation protocols on root canal treatment for bond strength to enamel and coronary dentin

Saudi Endodontic Journal, 2021
Introduction: The purpose of this study was to evaluate the effects of different concentrations of chitosan solution used as a final rinse after root canal treatment on the shear bond strength of composite resin to enamel and coronary dentin.

Composite electric S-brane solutions with maximal number of branes

, 2004
In this paper we consider (n+1)-dimensional cosmological model with scalar field and antisymmetric (p+2)-form. Using an electric composite Sp-brane ansatz the field equations for the original system reduce to the equations for a Toda-like system with n(n-

Dynamical Sieve of Eratosthenes

, 2011
In this document, prime numbers are related as functions over time, mimicking the Sieve of Eratosthenes. For this purpose, the mathematical representation is a uni-dimentional time line depicting the number line for positive natural numbers N, where each

Composite functional metasurfaces for multispectral achromatic optics [PDF]

Nature Communications, 2016
Nanostructured metasurfaces offer unique capabilities for subwavelength control of optical waves. Based on this potential, a large number of metasurfaces have been proposed recently as alternatives to standard optical elements.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
