A composite lens and a manufacturing method, and an infrared detector. The composite lens comprises a substrate (); a lens () located on the first surface of the substrate (); and a first metasurface structure array () that is provided on the second surface of the substrate () according to the surface type machining error of the lens (), the first metasurface structure array () comprising a plurality of metasurface structure units. The first surface is opposite to the second surface. Because the lens () and the first metasurface structure array () are located on two different surfaces of the substrate (), after the lens () is manufactured, the first metasurface structure array () can be set according to the surface type of the lens (), so as to correct an aberration that is generated due to a surface type error when the lens () is machined; moreover, because the first metasurface structure array () can be set after the lens () is manufactured, the tolerance to a machining error is extremely high.

Disclosed is a 1,3-bisisocyanatomethylcyclohexane composition and an optical resin prepared therefrom. The composition comprises, based on the weight of 1,3-bisisocyanatomethylcyclohexane, a) 65%-95 wt % of trans-1,3-bisisocyanatomethylcyclohexane; b) greater than 0 and less than or equal to 0.5 wt %, preferably 0.02-0.5 wt % of 1,4-bisisocyanatomethylcyclohexane. Preferably, the 1,3-bisisocyanatomethylcyclohexane composition contains greater than 0 and less than or equal to 600 ppm of 1-isocyanatomethyl-3-methylcyclohexane, based on the weight of 1,3-bisisocyanatomethylcyclohexane. The 1,3-bisisocyanatomethylcyclohexane composition is used for preparing an optical resin, which can be applied to produce an optical lens with a better performance in preventing opacification and optical distortion.

A polymer binder with high peel strength is used in a secondary lithium battery. The polymer binder is obtained by a ring-opening reaction of polyvinylene carbonate by a nucleophile. The polyvinylene carbonate accounts for 10-90% of the total mass of the polymer binder while the nucleophile accounts for 10-90% of the total mass of the polymer binder. The polymer binder has high peel strength (0.02-0.6 N/mm) and high decomposition voltages (4.5-6.0 V), and can be used as an electrode material binder in a secondary lithium battery.

Aspects of the disclosure relate to an efficient entirely man-made nanobio hybrid fabricated through cell-free expression of transmembrane proton pump followed by assembly of the synthetic protein architecture with semiconductor nanoparticles for photocatalytic Hevolution. The system produces Hat a turnover rate of 240 &#x3bc;mol of H(&#x3bc;mol protein)hunder green and 17.74 mmol of H(&#x3bc;mol protein)hunder white light at ambient conditions, in water at neutral pH with methanol as a sacrificial electron donor. Robsutness and flexibility of this approach allows for systemic manipulation at nanoparticle-bio interface toward directed evolution of energy materials and devices.
