Designing Polymer Nanocomposites for X‐Ray Shielding: Mechanisms, Architectures, and Scalable Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This review highlights advances in lightweight, lead‐free polymer nanocomposites for diagnostic X‐ray shielding. By linking filler chemistry, dispersion, architecture, and photon interaction mechanisms, it establishes structure–performance relationships guiding material design.

Hard glass-ceramic coating by microwave processing

open access: yes, 2008
Microwave processing was employed in the present work to obtain hard glass-ceramic coating on nickel based superalloy substrate. The glass-ceramic coatings were developed from a glass based on MgO-Al2O3-TiO2 system.

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

open access: yesAdvanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Upconversion luminescence and thermal effects in terbium-ytterbium codoped fluorogermanate glass-ceramic

open access: yes, 2009
Cooperative energy transfer upconversion luminescence is investigated in Tb(3+)/Yb(3+)-codoped PbGeO(3)-PbF(2)-CdF(2) glass-ceramic and its precursor glass under resonant and off resonance infrared excitation.

A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

The development and properties of glass-ceramic fibres [PDF]

open access: yes
Fibres were produced from glasses with the following compositions: A= 25% Li20 74% SiO2 1% P205 B= 29% LiO2 68% SiO2 1% P205 1% ZnO 1% K20 by drawing the fibres from a single tip platinum bushing.

An atomic scale comparison of the reaction of Bioglass® in two types of simulated body fluid [PDF]

open access: yes, 2009
A class of melt quenched silicate glasses, containing calcium, phosphorus and alkali metals, and having the ability to promote bone regeneration and to fuse to living bone, is produced commercially as Bioglass.

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Glass-ceramic glazes for future generation floor tiles

open access: yes, 2013
Glaze in the CaO-MgO-Al2O3-SiO2 system was heated at 950-1190 degrees C for 2 h and characterized. X-ray diffraction showed that only -brace amount of mullite was formed in the glass-ceramic glaze heated at 950 degrees C.

Ballistic and physical properties of highly fractured alumina [PDF]

open access: yes, 2010
It is known that ceramic materials in armour are often shattered by a penetrating projectile and the resistance to penetration is therefore dependent upon the properties of this failed material.
