Since 1975, clinical studies have been carried out to determine whether radiation when combined with localized hyperthermia evokes improved tumor control compared that achieved alone. Local was using radiofrequency inductive heating at 27.12 MHz. In bulky lesions (<100 cm3), conductive 13.56 MHz also used. More than 100 in 38 patients were treated alone and combination radiation. Most either twice a week or once week, depending on dose fractionation scheme The overall result of rate the...
A major problem in the application of mesoporous TiO2 as an electron transport layer for flexible perovskite solar cells is that a high-temperature sintering process required to remove organic additives from layer. facile oxygen plasma herein demonstrated fabricate mesoporous-structured with significant photovoltaic performance at low temperatures. When low-temperature processed modified via plasma, hinder charge are successfully decomposed. The treatment improves wettability and...
Abstract An electrical and optical responsive chemical‐semiconductor gas sensor is developed using Cu(I) halides with a phase transition mechanism. materials exhibit reversible transitions between the Cs 3 Cu 2 I 5 CsCu different properties, owing to formation/destruction of Cs–I Cu–Cu bonding when hydroxyl groups are attached/detached. Among various toxic atmospheric gases, Cu(I)‐based has high selectivity in detecting group, highest sensitivity water. The reactivity determined by polarity,...
We determine the influence of substitutional defects on perovskite quantum dots through experimental and theoretical investigations. Substitutional were introduced by trivalent dopants (In, Sb, Bi) in CsPbBr3 ligand-assisted reprecipitation. show that photoluminescence (PL) emission peak shifts toward shorter wavelengths when doping concentrations are increased. Trivalent metal-doped enhanced PL yield (~10%) air stability (over 10 days). Our findings provide new insights into substituted...
Dye-sensitized solar cells (DSSCs) have attracted intense scientific interest due to their low cost, environmentally friendly operation, and relatively high efficiency. In particular, solid-state fiber dye-sensitized (SS-FDSSCs) significant attention for potential applications in portable, flexible, wearable electronics. However, the use of general DSSCs these is limited by highly leak-susceptible volatile liquid electrolytes. Therefore, development a efficient stable electrolyte SS-FDSSCs...
Transmission electron microscopy images showed that self-assembled Ni1−xFex nanoparticle arrays were periodically inserted in the polyimide (PI) layers. Capacitance-voltage (C-V) measurements on Al/PI/multiple-stacked arrays/PI/p-Si (100) structures at 300K a metal-insulator-semiconductor capacitor behavior with different flatband voltage shifts, which depended value of sweep voltage, due to variations charged density multiple-stacked arrays. Conductance-voltage (G-V) conductance peak...
Fiber-shaped dye-sensitized solar cells (FDSSCs) with flexibility, weavablity, and wearability have attracted intense scientific interest development in recent years due to their low cost, simple fabrication, environmentally friendly operation. Since the Grätzel group used organic radical 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) as redox system (DSSCs) 2008, TEMPO has been utilized an electrolyte further improve power conversion efficiency (PCE) of cells. Hence, high catalyst oxidant...
Aiming at high efficiency of quantum dot-sensitized solar cells (QDSCs) with CdS dots (QDs)/mesoporous TiO2 (mp-TiO2) photoanodes, physical properties QDs/mp-TiO2 grown by sono-chemical successive ionic layer adsorption and reaction (SC-SILAR) process were studied. It is found that SC-SILAR has less growth time larger absorbance QDs besides a uniform penetration into mp-TiO2 films, compared the conventional SILAR process. Experimental results show an effective method for growing due to extra...
The significance of time-dose relationships in the use local tumor hyperthermia (LTH) when combined with radiation (RAD) was studied a murine fibrosarcoma. RAD, either alone or LTH, delivered four equal fractions (total doses, 1.8 to 4.2 krad) separated by 1 4 days. LTH (43.1 C ± .05 for 15 minutes, water bath) applied immediately after RAD. In this system, RAD most effective every 2nd 3rd day, factor 1.25 over response achieved were At all levels studied, + produced superior compared alone....
Fiber-shaped solar cells (FSCs) with flexibility, wearability, and wearability have emerged as a topic of intensive interest development in recent years. Although the this material is still its early stages, bacteriophage-metallic nanostructures, which exhibit prominent localized surface plasmon resonance (LSPR) properties, are one such that has been utilized to further improve power conversion efficiency (PCE) cells. This study confirmed fiber-shaped dye-sensitized (FDSSCs) enhanced by...
Plasmonic nanostructures, which exhibit notable localized surface plasmon resonance (LSPR) properties, are a promising approach for improving the efficiency of fiber‐shaped dye‐sensitized solar cells (FDSSCs) and flexible organic light‐emitting diodes (FOLEDs).
