Composites with excellent thermomechanical and thermochemical properties are urgently needed in the aerospace field, especially for structural applications under high-temperature conditions. Carbon fiber-reinforced Si-based composites considered most promising potential materials due to their oxidation resistance ablative behaviors, good designability, mechanical properties. The reinforcement o...

BACKGROUND Transepidermal drug delivery (TED) is a new potential method in dermatology. Permeability alterations induced by ablative fractional resurfacing have been described with the aim to increasing the delivery of different substances into the skin. OBJECTIVE To evaluate clinical response and side effects of TED in areata alopecia (AA) treatment using ablative fractional methods associat...

The purpose of this article is to present in a concise manner an overview of the most widely used locoregional transcatheter and ablative therapies for solid malignancies. An extensive MEDLINE search was performed for this review. Therapies used for liver cancer were emphasized because these therapies are used most commonly in the liver. Applications in pulmonary, renal, and bone tumors were al...

A one–dimensional, transient and thermal degradation model for predicting responses of composite materials when are exposed to the fire is presented. The presented model simulates ablation of composites with different layers of materials and considers material properties as functions of temperature. The reactions are modeled by using Arrhenius-type parameters and density-temperature diagram...

The thermal load protection of hypersonic and space vehicle structures can be achieved by either passive or active methods, such as ablative materials or active cooling. For the latter, porous Ceramic Matrix Composite media offer a possibility to exploit thermal protection by means of transpiration cooling due to their higher permeability. One of the related key issues is the determination of p...

A new era in dermatological cosmetology, especially in the field of nonsurgical skin rejuvenation, started with ablative resurfacing, at first by carbon dioxide laser and later by Er:YAG or their combination. Although ablative lasers result in major improvements in photodamaged skin, the related postoperative recovery time and side effects are currently unacceptable for most patients. During th...

In the present studies, silicon based low-density ablative material has been studied for its performance to protect flight hardware from temperature raises due aerodynamic forces a longer duration. The oxyacetylene flame test estimates properties at 100–120 W/m2 heat flux. time duration is taken 200 s. shows low mass and linear ablation rate with high effectiveness. degradation kinetics of abla...

Non-ablative skin tightening is a newer approach to tissue remodeling and skin rejuvenation employing noninvasive procedures. These procedures produce less dramatic effects in comparison to traditional ablative laser resurfacing, but also significantly less healing time and patient discomfort. A variety of non-ablative procedures have been developed to achieve skin tightening through dermal the...
