Physical structure for use in a physical unclonable

The invention relates to a semiconductor device comprising a physical structure (50) for use in a physical unclonable function, wherein the physical structure (50) comprises a lead-zirconium titanate layer (25), and a silicon-comprising dielectric layer (27) deposited on the lead-zirconium-titanate layer (25), wherein the silicon-comprising dielectric layer (27) has a rough surface (SR), the physical structure (50) further comprising a conductive layer (30) provided on the rough surface (SR) of the silicon-comprising dielectric layer (27). The invention further relates to a method of manufacturing such semiconductor device. The invention also relates to a card, such as a smartcard, and to a RFID tag comprising such semiconductor device. The inventors have found that depositing of a silicon- comprising dielectric layer (27) on a lead-zirconium titanate layer (25) using vapor deposition results in a silicon-comprising dielectric layer (27) having a rough surface (SR). This rough surface (SR) can be used in a PUF to make a resistor (R) with a variable random value by depositing a conductive layer (30) on the rough surface (SR). Alternatively, the combination of both layers (25, 27) can be used in a PUF as composite dielectric to make a capacitor (C) with a variable random capacitance value.

Controllable crystalline form titanium dioxide and graphite alkene composite material with high efficient photoelectricity activity and preparation method thereof

The invention discloses controllable crystalline form titanium dioxide and a graphite alkene composite material with high efficient photoelectricity activity and a preparation method thereof. The composite material is formed by mixing TiO2 powder and graphite alkene or scattering the TiO2 powder in oxidized graphite alkene dispersing agents to perform hydro-thermal reaction. The mass ratio of TiO2 powder and graphite or graphite alkene is 1:1 to 500:1. The preparation method is simple, low in cost and environmental-friendly. The controllable crystalline form titanium dioxide and a graphite alkene composite material with high efficient photoelectricity activity can control crystalline form of the obtained TiO2 according to the ratio of alcohol and water or amount of titanium sources. When the amount is amplified, the controllable crystalline form titanium dioxide and a graphite alkene composite material with high efficient photoelectricity activity have good performances. After the graphite alkene is composed, photocatalysis is greatly improved. All obtained products are applied to fields of dye sensitization solar cells, catalysts, lithium ion cells, sensing and the like.

Single screw bridgeplate

The present invention is a cartridge bridge plate assembly for mounting under a floor structure of a transit vehicle adjacent a door opening. It has a frame assembly and means for attaching the frame assembly underneath the floor structure of the vehicle. It has a bridge plate for covering a gap between the floor of the vehicle and an adjacent surface to facilitate passenger ingress and egress when the vehicle is stopped. It has a bridge plate positioning means for positioning the bridge plate and accommodating motion of the bridge plate from a stowed position within the frame assembly to an extended position for covering the gap. A motor is connected to the bridge plate positioning means for moving the bridge plate from the stowed position to the extended position and from the extended position to the stowed position. The system includes a power connection to the motor, and a drive screw connected to and rotated by the motor. It has a drive nut engaging the drive screw to be translated thereby, the drive nut having mechanical connection to the bridge plate positioning means to move the bridge plate from the stowed position to the extended position and from the extended position to the stowed position. The system also has an elevating means connected to the bridge plate positioning means for elevating an inner edge of the bridge plate to match an elevation of the floor surface of the transit vehicle.

Bacillusamyloliquefaciens subsp Lh-1 and application thereof

The invention relates to the field of microbial control, in particular to bacillusamyloliquefaciens subsp Lh-1 and application thereof. With a preservation number of CGMCC No.8548, the bacillusamyloliquefaciens subsp Lh-1 is applied in control of Verticillium dahliae, erwinia carotovora, ralstonia solanacearum, valsa leucostoma, Valsa Mali Miyabe et Yamada, Phytophthora capsici and phytophthora infestans. According to the invention, the bacillusamyloliquefaciens subsp Lh-1 and pesticide and chitosan oligosaccharide with dual effects of fertilizer and pesticide are combined into an Lh-1 microecological agent, the viable count is small, the dosage is small, the production process is simple, the cost is low, and the Lh-1 microecological agent has the dual functions of disease prevention and growth promotion. Nursery test proves that reduce the disease incidence of crop is reduced, especially for control of Verticillium dahliae, the disease incidence drops to 6%, and the control effect is significant. In addition, the Lh-1 microecological agent is a biological strain preparation, is completely free of a series of problems caused by use of chemical pesticides, thus being conducive to pollution-free production of crops, and farmers can have no need for pesticide or reduce the dosage of chemical pesticide, thus greatly saving the expenditure.
