Many photovoltaic (PV) parks suffer from a decrement in their generated power capability due to phenomenon called potential induced degradation (PID). In this paper, regenerative system using high step-up DC–DC converter is proposed, for regenerating PV cells that have been degraded the PID effect. The same device also can be used artificially creating on panels order study effects of under con...

At the past, damaged tissue was removed from the body of patients. But now tissue regeneration using scaffolds and implants are used to repair the damaged tissue and organs. Besides of the mechanical properties of metallic biomaterials, they suffer from bioinertness. Using some surface treatment techniques, the bioactivity and also corrosion resistance of titanium implants could be improved. In...

The purpose of this review article is to potentiate the use of nanogel based artificial chaperones as therapeutic approach in delivery of various molecules. Nanogel is a nanoscale drug delivery systems with enhanced surface area not only are capable of transmitting hydrophobic drugs in vitro and in vivo with improved drug bioavailability but also help to reduce side effects of drug. Nanogel cha...

Introduction In some regions of the world viral hepatitis is a common disease that can be severe enough to result in severe decrease in liver function and death. Liver transplantation is an effective treatment. However, it involves major surgery and it also depends on the very limited availability of donor livers. The same can also be said for extensive liver resection for metastatic cancer or ...

Due to the lack of regeneration methods, the reusability of nanofluidic chips is a significant technical challenge impeding the efficient and economic promotion of both fundamental research and practical applications on nanofluidics. Herein, a simple method for the total regeneration of glass nanofluidic chips was described. The method consists of sequential thermal treatment with six well-desi...

In some traumatic nerve injuries, autologous nerve grafting is the first choice for bridging the gap between the severed nerve ends. However, this therapeutic strategy has some disadvantages, including permanent loss of donor function and requirement of multiple surgeries. An attractive alternative to this therapeutic technique is the use of artificial nerve conduit. Poly (L-lactic acid) (PLLA)...

In recent years, significant progress has been made in organ transplantation, surgical reconstruction, and the use of artificial prostheses to treat the loss or failure of an organ or bone tissue. In recent years, considerable attention has been given to carbon nanotubes and collagen composite materials and their applications in the field of tissue engineering due to their minimal foreign-body ...

Tail-tip clipping is a common technique for collecting tissue samples from amphibian larvae and adults. Surprisingly, studies of this invasive sampling procedure or of natural tail clipping--i.e., bites inflicted by predators including conspecifics--on the performance and fitness of aquatic larval stages of urodeles are scarce. We conducted two studies in which we assessed the effects of poster...
