RIGHT TIGHT HEAVENS

1. INTRODUCTION  The microscale heat transfer finds a lot of interesting applications in the biomedical industry. There is hot research going on in this area, especially associated with drug delivery and cancer therapy. The microscale heat transfer phenomenon through the tissues is an area that needs to be exploited for developing a full-proof system to heat the tumors present in the tissues and provide a feasible solution to cancer therapy. Hyperthermia therapy (or hyperthermia, or thermotherapy) is a type of medical treatment in which body tissue is exposed to temperatures in the region of 40-45°C. Hyperthermia is usually applied as an adjuvant to Radiotherapy or Chemotherapy, to which it works as a sensitizer, in an effort to treat cancer. Hyperthermia uses higher temperatures than diathermy and lower temperatures than ablation. When combined with radiation therapy, it can be called thermoradiotherapy. There are three important types of hyperthermia; they are as follows: • Local hyp

The exploitation of the conventional sources of energy has reached the extremum already, so switching to renewable sources of energy is the motto of the future. The conventional sources of energy are depleting at an alarming rate. A large amount of heat is released as waste heat from the existing energy conversion systems, so technologies that can help in recycling or recovering the waste heat along with increasing the overall efficiency of the existing energy conversion systems and devices is the need of the hour. The thermophotovoltaic (TPV) devices do the same thing. Figure 1: Thermophotovoltaic cell   TPV helps recycle the waste heat very efficiently. This device makes use of the photovoltaic effect by which the photons whose energy is larger than that of the bandgap of the TPV cell will be able to generate electron-hole pair. In this device, a junction is formed between the semiconductor layers, which are doped unevenly. This junction creates a potential barrier inside the cell.
