A method for removing particulate matter from a particulate-bearing gas stream includes flowing a particulate-bearing gas stream at a first volumetric flow rate to a plurality of ESP units; producing electrically charged particulate matter; collecting electrically charged particulate matter on collection electrode plates; reducing the flow through at least one of the ESP units; sequentially increasing the flow through one or more remaining ESP units in an amount so as to maintain the sum of flow through all of the ESP units at the first volumetric flow rate; subjecting the collection electrode plates in the at least one ESP unit with reduced flow to forces which dislodge the particulate matter from the collection electrode plates; collecting the dislodged particulate matter in a particulate collection receptacle; and withdrawing a gas stream of reduced particulate matter contamination.

Additive particles for use in a fluid catalytic cracking system are provided for reducing the opacity of flue gas that is generated from a regenerator within the system. Particles are supplied to the unit to catalyze the cracking of hydrocarbon feeds, and to react with sulfur oxides that are produced during regeneration of catalysts supplied for the cracking reactions. At least a portion of the supplied particles include active particulates and a binder, with at least a portion of the active particulates being in a size range from 0.5 to 40 microns.

A new class of the memory cell is proposed. There are two separated pulse data writing and sensing current paths. The in-plane pulse current is used to flip the magnetization direction of the perpendicular-anisotropy data storage layer sandwiched between a heavy metal writing current-carrying layer and a dielectric layer. The magnetization state within data storage layer is detected by the patterned perpendicular-anisotropy tunneling magnetoresistive (TMR) stack via the output potential of the stack. Two detailed memory cells are proposed: in one proposed cell, the data storage layer is independent from but kept close to the sensing TMR stack, whose magnetization orientation affects magnetization configuration within the free layer of the TMR stack, therefor ultimately affects the output potential of the stack; in the other proposed cell, the perpendicular-anisotropy data storage layer is the free layer of the sensing TMR stack, whose magnetization state will directly affect the output potential of the stack when sensing current passes through.

A air purification system, whose air flow pipeline made of highly reflective and low absorptive material for UVC or UVB light acts also as a UV light waveguide, with a UVC and/or UVB LED built inside the pipeline, is invented. The system is based on the design concept of maximizing UV light exposure dosage to deactivate all the bioaerosols in the air flow pass through the system. The proposed system can be easily integrated into travel pillow, backbag, handbag, belt bag as well as air supply systems for public and private transport systems. The system provides purified air supply for travelers in the closed environment such as in a airplane, or on a train against various dangerous viruses including COVID-19 and SARS virus. It can also be used in office during flu season as well as provide cleaned air supply to its users against the hay-fever.

A CMOS compatible material platform for photonic integrated circuitry is invented. The material platform has SiO2 as cladding material, at least a bottom layer made of moderate refractive index material(s) fabricated first on a unpatterned SOI wafer, a bonded system substrate, a set of photonic circuitry made within a SOI layer of the SOI wafer after its substrate and BOX layer removed, and some coupling devices enabling light travelling between the devices made within these two layers. A solution to provide IIIV laser diodes boned and embedded in the system substrate is also proposed. The invention provides a great material platform to offer full set of photonic building blocks for all sort of different applications such as photonic circuitry for optical neural network, quantum computing, telecommunication, data communication, optical switching, optical sensing, passive and/or active Si optical interposer with its size even bigger than lithography step field size.

A portable or handhold air purification system, whose air flow pipeline made of highly reflective and low absorptive material for UVC or UVB light acts also as a UV light waveguide, is invented. The system is based on the design concept of maximizing UV light exposure dosage to deactivate all the pollutants in the air flow going through to allow the system to use UVC and/or UVB LED. The system also has some features around the middle point of the air flow path to either further increase light exposure, or clean the air flow through the interaction between the specially designed nano particles and incoming UV light. Moreover, an ozone filter and an air heating devices, with energy either from the heat sink of LED's TEC or a device based on plasmonic resonance induced photothermal effects, are placed near the air outlet of the system for further enhancement. The system is very useful for travelers in the closed environment such as in a airplane, or on a train. It can also use in office during flu season as well as provide cleaned air supply to its users against the hay-fever.
