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 derived from rice husk [...]

Bone tissue engineering (BTE) as a modern and more effective treatment for bone defects has recently received lots of attention. One of the pivotal parts of BTE is the “scaffold”, which functions as an indwelling carrier of cells and additives, as well as, providing a foundation for cell growth and eventually forming new, native-like bone. Up to now, many methods and materials have been employed to manufacture bone scaffolds. This review focuses on providing both basic knowledge of BTE as well as possible methods o [...]

Lung transplantation is a last-resort treatment option for patients with end stage lung disease. The procedure is being performed more frequently and scientific advances continue to be made, but the median post-transplant survival is far shorter than other solid organ transplant recipients. Candidate selection is a resource intensive process that attempts to balance risks of the procedure with the benefits of much higher quality of life. Transplant centers must weigh disease specific considerations, medical comorbi [...]

Polymers such as polyimides and fluoropolymers are widely used for insulating aeronautic wires. They are exposed to various changing factors such as temperature, pressure, moisture, vibration, chafing, etc. The electrification on the horizon can potentially increase the demand for these systems. Indeed, this impending evolution of technology pushes the boundaries of commonly-employed wires. Downsizing systems and enhancing the performance is an urgent requirement. A new generation of insulating materials capable of [...]

The term chimera refers to an organism with cell lines from two or more distinct zygotes. Human chimerism may occur naturally or artificially. Although rare, advancements in genetics and genomics have resulted in the identification of additional natural human chimeras. Three forms of naturally occurring chimerism have been documented in humans: blood group chimerism, microchimerism, and fusion chimerism. Fusion chimerism may occur through several means. Sex-chromosome discordant chimerism refers to individuals with [...]

Awareness of the challenges of sustainable development, and in particular the risks of climate change, is leading to inevitable restrictions on Greenhouse gas emissions. True carbon risk management must be introduced into the strategy of companies that will increasingly operate in a global low-carbon economy. Indeed, companies are now called upon to be accountable and transparent about the environmental consequences of their business activities. Carbon risk is one of several new emerging risks for companies associa [...]
