BACKGROUND Effective malaria vector control targeting indoor host-seeking mosquitoes has resulted in fewer vectors entering houses in many areas of sub-Saharan Africa, with the proportion of vectors outdoors becoming more important in the transmission of this disease. This study aimed to develop a gravid trap for the outdoor collection of the malaria vector Anopheles gambiae s.l. based on evalu...

Microsphere arrays can be used to effectively detect, identify, and quantify biological targets, such as mRNAs, proteins, antibodies, and cells. In this work, we design a microfluidic microsphere-trap array device that enables simultaneous, efficient, and accurate screening of multiple targets on a single platform. Different types of targets are captured on the surfaces of microspheres of diffe...

The integration of multiple materials with complementary absorptions into a single junction device is regarded as an efficient way to enhance the power conversion efficiency (PCE) of organic solar cells (OSCs). However, because of increased complexity with one more component, only limited high-performance ternary systems have been demonstrated previously. Here we report an efficient ternary ble...

Quantum computers can provide solutions to certain classically intractable problems. However, current devices have limited computational resources, and an effort is made develop useful quantum algorithms under this constraint. This work demonstrates experimentally that a single-qubit processor host universal classifier based on the re-uploading scheme. The used in built with ion trap, providing...

We observe optical trapping and manipulation of dielectric microparticles using autofocusing radially symmetric Airy beams. This is accomplished by exploiting either the inward or outward transverse acceleration associated with their chirped wavefronts. We experimentally demonstrate, for the first time to our knowledge, that such Airy beams morph into nondiffracting Bessel beams in their far-fi...

a faunistic list of syrphidae sampled in the agroecosystems of neyshabur (khorasan-razavi province) through malaise, yellow water traps and hand net is hereby presented for the first time. a total of 22 species were collected, including 13 species through malaise trap, 5 through yellow water trap as well as representatives of all species sampled through hand net. among the species collected, 8 ...

A device has been developed for the direct in situ measurement of metal remobilization into solution from settling particles in water columns, based on the technique of diffusion gradients in thin films (DGT). The device comprises a hollow cylinder with a DGT assembly at its base and acts as a traditional sediment trap, except that any remobilization from settling particles is reflected in the ...

Trap-assisted recombination, despite being lower as compared with traditional inorganic solar cells, is still the dominant recombination mechanism in perovskite solar cells (PSCs) and limits their efficiency. We investigate the attributes of the primary trap-assisted recombination channels (grain boundaries and interfaces) and their correlation to defect ions in PSCs. We achieve this by using a...

Through a combination of measurement techniques, we study the interface properties of In0.65Ga0.35As transistor with ALD deposited Al2O3 gate dielectric. We show that the interface trap density at In0.65Ga0.35As/Al2O3 interface can be relatively high, but the transistor still exhibits inversion characteristics. A detailed profiling of the interface traps shows that majority of the interface tra...
