Cover Story:Even when obtained under comparable conditions, biochars derived from different feedstocks can have a wide-ranging ability to remove dyes. The selection of suitable biochars for methylene blue removal from aqueous solutions was based on their PZC values and indicated a direct dependency on the biochars’ surface charge and pH.View this paper

Solubility of Dental Ceramics in Electric FieldsAbstract Combining dental ceramics with other prosthetic metallic restorations might release metal ions, thus affecting the oral tissues of the patients. In this study, we evaluated the electrochemical solubility of various dental ceramics in a galvanic experimental setup in vitro. Smooth and rough feldspathic and zirconium dioxide ceramics (at pH 5.5 and pH 3.0) were exposed to an electric field. Calcium, barium, and zirconium were selected as parameters to determine the solubility of both types of cera [...] |
Modifications of Glass Ionomer Cements Using Nanotechnology: Recent AdvancesAbstract Glass ionomer cements (GICs) are dental materials that were invented by Wilson & Kent in 1972. They can chemically bond to enamel and dentin and can exhibit anti-cariogenic activity that allows the release and uptake of fluoride ions. They also possess the ability to render color. The setting reaction of GICs is a neutralization reaction that results in the formation of polycarboxylate salts. The most important GIC modification process involves the addition of resin components, resulting in [...] |

Abstract The point of zero charge (PZC) is an inherent electrokinetic property of biochars (BC). It influences the adsorption process under certain pH conditions. Herein, we report the method of determination of the PZC values of ten standard BCs. We used the salt addition method to select the BCs with suitable properties for methylene blue (MB) removal from aqueous solutions. The standard BCs were obtained by pyrolyzing five different biomasses at two distinct temperatures (550°C and 700°C). The BCs der [...] |

Abstract Shape memory polymers (SMPs) are smart materials that can respond to certain thermal, chemical or electrical stimuli by inducing a structural conformation change into a temporary shape. In this work, a 3D printing process based on a Vat Photo-polymerization of a shape memory polymer (SMP) was investigated to produce customized smart and complex morphable antennas. The mechanical and material properties were examined through a tensile, flexural and rheological testing for different polymer mixtur [...] |
Development of Low Elastic Modulus Titanium Alloys as Implant BiomaterialsAbstract Biomaterials have always been the focus of material scientists and engineers. Titanium and its alloys have favorable properties, such as high strength, low density, good corrosion resistance, non-toxicity, low elastic modulus, biocompatibility, etc. Thus, Ti alloys have received much attention from scientists and engineers who work with biomaterials. Among these properties, the elastic modulus is a very important property for implant biomaterials because it avoids the “stress shielding” effect. [...] |

Reaction Kinetics and Characterization of Slag-Based, High Strength, “Just-Add-Water” Type (One-Part) Alkali-Activated BindersAbstract The influence of different levels of alkalinity, expressed using M2O-to-binder ratio (n) and activator SiO2-to-M2O ratio (Ms), (M being the Na+ or K+ cation) on the reaction kinetics, compressive strength development and the reaction product formation in slag-based systems activated using alkali powders are discussed.
