Delocalization of Electrons in Strong Insulators at High Dynamic Pressures.

Materials (Basel, Switzerland)

Nellis WJ.
PMID: 28879973
Materials (Basel). 2011 Jun 21;4(6):1168-1181. doi: 10.3390/ma4061168.

Systematics of material responses to shock flows at high dynamic pressures are discussed. Dissipation in shock flows drives structural and electronic transitions or crossovers, such as used to synthesize metallic liquid hydrogen and most probably Al₂O₃ metallic glass. The...

Organic Zeolite Analogues Based on Multi-Component Liquid Crystals: Recognition and Transformation of Molecules within Constrained Environments.

Materials (Basel, Switzerland)

Ishida Y.
PMID: 28879985
Materials (Basel). 2011 Jan 11;4(1):183-205. doi: 10.3390/ma4010183.

In liquid crystals (LCs), molecules are confined in peculiar environments, where ordered alignment and certain mobility are realized at the same time. Considering these characteristics, the idea of "controlling molecular events within LC media" seems reasonable. As a suitable...

Electronic and Structural Properties of ABO3: Role of the B-O Coulomb Repulsions for Ferroelectricity.

Materials (Basel, Switzerland)

Miura K, Azuma M, Funakubo H.
PMID: 28879987
Materials (Basel). 2011 Jan 17;4(1):260-273. doi: 10.3390/ma4010260.

We have investigated the role of the Ti-O Coulomb repulsions in the appearance of the ferroelectric state in BaTiO3 as well as the role of the Zn-O Coulomb repulsions in BiZn0.5Ti0.5O3, using a first-principles calculation with optimized structures. In...

A New Highly Bioactive Composite for Scaffold Applications: A Feasibility Study.

Materials (Basel, Switzerland)

Bellucci D, Cannillo V, Sola A.
PMID: 28879993
Materials (Basel). 2011 Jan 28;4(2):339-354. doi: 10.3390/ma4020339.

Hydroxyapatite (HA) has been widely investigated as scaffolding material for bone tissue engineering, mainly for its excellent biocompatibility. Presently, there is an increasing interest in the composites of hydroxyapatite with bioactive glasses, with the aim to obtain systems with...

Coalescence and Collisions of Gold Nanoparticles.

Materials (Basel, Switzerland)

Antúnez-García J, Mejía-Rosales S, Pérez-Tijerina E, Montejano-Carrizales JM, José-Yacamán M.
PMID: 28879995
Materials (Basel). 2011 Jan 28;4(2):368-379. doi: 10.3390/ma4020368.

We study the assembling of small gold clusters subject to collisions and close contact coalescence by using molecular dynamics simulations to simulate events that occur typically in the sputtering process of synthesis. Our results support the notion that the...

Progress in Nano-Engineered Anodic Aluminum Oxide Membrane Development.

Materials (Basel, Switzerland)

Poinern GEJ, Ali N, Fawcett D.
PMID: 28880002
Materials (Basel). 2011 Feb 25;4(3):487-526. doi: 10.3390/ma4030487.

The anodization of aluminum is an electro-chemical process that changes the surface chemistry of the metal, via oxidation, to produce an anodic oxide layer. During this process a self organized, highly ordered array of cylindrical shaped pores can be...

Towards Understanding the Polymerization Process in Bitumen Bio-Fluxes.

Materials (Basel, Switzerland)

Król JB, Niczke Ł, Kowalski KJ.
PMID: 28891929
Materials (Basel). 2017 Sep 09;10(9). doi: 10.3390/ma10091058.

Bitumen is a commonly used material for road construction. According to environmental regulations, vegetable-based materials are applied for binder modification. Fluxed road bitumen containing a bio-flux oxidation product increases the consistency over time. The efficiency of crosslinking depends on...

A Graphene-Based Flexible Pressure Sensor with Applications to Plantar Pressure Measurement and Gait Analysis.

Materials (Basel, Switzerland)

Lou C, Wang S, Liang T, Pang C, Huang L, Run M, Liu X.
PMID: 28891991
Materials (Basel). 2017 Sep 11;10(9). doi: 10.3390/ma10091068.

In the present study, we propose and develop a flexible pressure sensor based on the piezoresistive effect of multilayer graphene films on polyester textile. The pressure response results from the deformation of graphene conductive network structure and the changes...

Interfacial Bonding Energy on the Interface between ZChSnSb/Sn Alloy Layer and Steel Body at Microscale.

Materials (Basel, Switzerland)

Wang J, Xia Q, Ma Y, Meng F, Liang Y, Li Z.
PMID: 28946690
Materials (Basel). 2017 Sep 25;10(10). doi: 10.3390/ma10101128.

To investigate the performance of bonding on the interface between ZChSnSb/Sn and steel body, the interfacial bonding energy on the interface of a ZChSnSb/Sn alloy layer and the steel body with or without Sn as an intermediate layer was...

Self-Assembled Gold Nano-Ripple Formation by Gas Cluster Ion Beam Bombardment.

Tilakaratne BP, Chen QY, Chu WK.
PMID: 28885577
Materials (Basel). 2017 Sep 08;10(9). doi: 10.3390/ma10091056.

In this study, we used a 30 keV argon cluster ion beam bombardment to investigate the dynamic processes during nano-ripple formation on gold surfaces. Atomic force microscope analysis shows that the gold surface has maximum roughness at an incident...

Impact of Surface Potential on Apatite Formation in Ti Alloys Subjected to Acid and Heat Treatments.
