We report a dramatic and irreversible reduction in the lattice thermal conductivity of bulk crystalline silicon when subjected to intense plastic strain under a pressure of 24 GPa using high-pressure torsion (HPT). Thermal conductivity of the HPT-processed samples were measured using picosecond time domain thermoreflectance. Thermal conductivity measurements show that the HPT-processed samples ...
We report on the temperature dependence of thermal conductivity of single crystalline and polycrystalline organometallic perovskite CH3NH3PbI3. The comparable absolute values and temperature dependence of the two samples' morphologies indicate the minor role of the grain boundaries on the heat transport. Theoretical modeling demonstrates the importance of the resonant scattering in both specime...
The eradication of Trichophyton rubrum has been attempted via laser irradiation because it could result advantageous relative to current clinical therapies. Anticipating that the necessary thermal effects could unintentionally damage the underlying toe dermal layer, we have explored two auxiliary approaches: (a) laser irradiation under vacuum pressure, with and without water dousing and, (b) co...
The increasing interest in the extraordinary thermal properties of nanostructures has led to the development of various measurement techniques. Transient thermoreflectance method has emerged as a reliable measurement technique for thermal conductivity of thin films. In this method, the determination of thermal conductivity usually relies much on the accuracy of heat capacity input. For new nano...
Background/introduction Within the focal point of focused ultrasound (FUS), high pressure fluctuations cause shear stress on cells and tissues with energy dissipation leading to heating of the targeted tissue. The extent of the mechanical and thermal effects strongly depends on the ultrasound parameters and also potentially the acoustic properties of the tumor. High temperatures lead to coagula...
Heat stress conditions lead to neuroinflammation, neuronal death, and memory loss in animals. Coptidis Rhizoma (CR) exhibits potent fever-reducing effects and has been used as an important traditional medicinal herb for treating fever. However, to date, the effects of antipyretic CR on heat-induced brain damages have not been investigated. In this study, CR significantly reduced the elevation o...
در حال حاضر رنگدانه های گروه آزو یکی از بزرگترین گروه رنگدانه های مصرفی در صنعت نساجی هستند. روش هایی که برای تصفی? فاضلاب ها مورد استفاده قرار می گیرند، همانند سیستم-های تصفی? اولیه و ثانویه، در حذف رنگدانه ها و معرف ها ناموفق عمل می نمایند. برای مثال فرآیندهای جذب و انعقاد مواد شیمیایی دو روش بکار رفته در تصفیه فاضلاب هستند. اما این روش ها صرفاً رنگدانه ها را از فاز مایع به فاز جامد انتقال می ...
PURPOSE Gold nanoshells (NSs) have already shown great promise as photothermal actuators for cancer therapy. Integrin αvβ3 is a marker that is specifically and preferentially overexpressed on multiple tumor types and on angiogenic tumor neovasculature. Active targeting of NSs to integrin αvβ3 offers the potential to increase accumulation preferentially in tumors and thereby enhance therapy effi...
Severe burns and other chronic inflammatory diseases are associated with altered skeletal metabolism that result in an increased incidence of osteopenia. In thermally injured children and adults there is a dramatic decrease in bone formation accompanied with an increase or maintenance of bone resorption. Children also exhibit a growth delay and subsequently fail to reach a predicted stature. An...
