Abstract:
The present invention relates to a hollow sphere with a mesoporous structure, and a method for manufacturing the same. The hollow sphere with a mesoporous structure comprises: a shell with plural mesopores penetrating the shell, wherein the shell comprises: a mesoporous silicon oxide material, and mesopores of the mesoporous silicon oxide material are arranged in Ia3d cubic symmetry. In addition, according to the method of the present invention, the aforementioned hollow sphere with the mesoporous structure can be easily obtained by use of mixed surfactants of a cationic surfactant and a non-ionic surfactant.
Abstract:
A smoke exhausting device is disclosed. It includes a housing partitioned into two internal rooms. One of the rooms is a bellows for creating pressure, while the other is a guide box for guiding the smoke. The bellows has an entrance communicated with the guide box and an exit communicated with outer side of the housing. The guide box surrounds a front side, right side, left side and a bottom face of the bellows and is spaced from the bellows to define a path for air flow to smoothly pass therethrough. Each of the three sides is disposed with at least one sucking mouth, which is communicated with the entrance. A bottom of the housing is formed with a downward inclined oil guiding section having an oil outlet at bottom end. The housing can be easily disassembled from the funnel and the sucking mouths of the guide box can be disposed at different positions in different directions, so that the smoke exhausting device is applicable to different sites.
Abstract:
A channel-type mesoporous material with an elliptical pore section has a 2D-rectangular pore arrangement. Besides, the channel-type mesoporous material includes silica and has a unit cell ratio a/b satisfying the inequality of √{square root over (3)}
Abstract:
A network for an oil-smoke exhausting device includes multiple cone-shaped nets separately piled up to one another and adapted to be mounted under an inlet of the oil-smoke exhausting device. Each net has a close end and an open end. The close end has a diameter smaller than that of the open end and the open end is adapted to be mounted around an inlet of the oil-smoke exhausting device. A flange radially outwardly extends from the open end of each of the nets and abuts one another. A washer is mounted between each two adjacent nets to form a chamber between each two adjacent nets. A fastening member securely extends through the cone-shaped nets and the wash ers to hold the washers in place. A frame is mounted around the open ends of each of the cone-shaped nets to combine the flanges securely abutting one another.

Abstract:
A method of preparing channel-type mesoporous material with an elliptical pore section is described. An alkaline solution containing two surfactants different in the electronic properties of their hydrophilic groups is prepared. A silica precursor is added to form a stack of rod-like micelles each having an elliptical section with the silica precursor between the rod-like micelles. The silica precursor is reacted into a silica framework. The rod-like micelles are removed from the silica framework.
Abstract:
A steering wheel lock including a lock body, a U-shaped shackle bar mounted on the lock body for securing to the lock body to the rim of the steering wheel to be locked, a hook bar integral with the lock body for hooking on the rim of the steering wheel, and a polygonal stop bar fixed to the lock body for stopping at a fixed location inside the motor vehicle, the polygonal stop bar having square drive ends at both ends for use as L-shaped wrench means for turning bolts and nuts by means of sockets.
