摘要:
A photovoltaic device and method of making a photovoltaic device are disclosed. The method includes laminating an organic layer onto an inorganic semiconductor layer. A first electrical contact is electrically coupled to the organic layer and a second electrical contact is coupled to the inorganic semiconductor layer. The inorganic semiconductor layer may include a second organic layer. At least one of the organic layer and the second organic layer may form a heterojunction with the inorganic semiconductor layer. The organic layer may further comprise a metal layer. At least one of the organic layer, the inorganic semiconductor layer and the metal layer may be patterned.

A method for determining pectin content in a plant sample includes: 1) adding an acidic alcohol solution to the plant sample, heating in a water bath and filtration; 2) soaking residue from step 1 with an acidic solution, heating in a water bath, a second filtration, bringing to volume after cooling and obtaining filtrate; 3) adding an acetic acid/sodium acetate buffer solution to residue of step 2, adding a pectinase solution, heating under vibration in a water bath, and a third filtration to obtain a filtrate; 4) adding an acetic acid/sodium acetate buffer solution and a pectinase solution to filtrate from step 2, heating the mixture under vibration in a water bath to obtain an enzymatic hydrolysate, adding filtrate obtained in step 3 to the enzymatic hydrolysate, bringing to volume, and obtaining a test solution; 5) drawing the test solution into a continuous flow analyzer to perform analysis.
摘要:
An implantable direct cardiac compression (DCC) device (101) has a body (102) comprising a flexible frontal cardiac compression wall (103) and a rear wall (104) together defining a pressurisable chamber (106). The cardiac compression wall (103) is adapted to be affixed to the wall of a ventricle (21) of a heart (20) and to compress the ventricle (21) upon pressurisation of the chamber (106). The device (101) is provided with two flexible flaps, one extending from each of two of opposing lateral sides of the body (102), adapted to be affixed to the ventricle wall (23). An implantable DCC system comprises left and right DCC devices (101, 201) for affixing to the left and right ventricles (21, 22). Straps (216) are provided on the right DCC device (206) for wrapping around the heart (2) and left DCC device (101) to secure the DCC devices (101, 201) to the left and right ventricles (21, 22) respectively.
摘要:
Disclosed is a method for determining pectin content in a plant sample, comprising the following steps: 1) adding an acidic alcohol solution to the plant sample, then heating the resulting mixture to reflux in a water bath, followed by a first filtration; 2) soaking the filtered residue obtained from the first filtration with an acidic solution, then heating the resulting mixture to reflux in a water bath, followed by a second filtration, then bringing to volume after cooling, obtaining filtrate for later use; 3) adding an acetic acid/sodium acetate buffer solution to treat the filtered residue obtained from the second filtration, then adding a pectinase solution and heating the resulting mixture under vibration in a water bath, followed by a third filtration to obtain a filtrate for later use; 4) sequentially adding an acetic acid/sodium acetate buffer solution and a pectinase solution to the filtrate obtained in step 2) and heating the resulting mixture under vibration in a water bath to obtain an enzymatic hydrolysate, then adding the filtrate obtained in step 3) to the enzymatic hydrolysate followed by bringing to volume, obtaining a test solution; and 5) drawing the test solution into a continuous flow analyzer to perform analysis. The method disclosed has the advantage of providing accurate analysis results.
摘要:
A heart actuator device for use in heart assist apparatus, which device includes a paddle-like main body. The main body has a heart compressing wall, which in use is adapted to be affixed to at least a region of heart, and a distal wall, which in use is adapted to be distal that region of the heart. The heart compressing wall is movable in a direction relatively away from the distal wall, so as, in use to compress at least that region of the heart thereby assisting movement of the heart wall.
