A method of viewing a live image from a microscope through a camera lens of a first personal electronic device is described. The method includes receiving one or more optic powers of a microscope taking the live image entered into a first graphical user interface displayed on a screen of the first personal electronic device, and projecting a measurement tool on a second graphical user interface displayed on the screen of the first personal electronic device with units of measurement based on the entered optic powers. One or more non-transitory, computer-readable storage media and a computer or computer system are also described. Hardware designed to connect a personal electronic device such as a smartphone to a microscope for viewing of a live microscope image through the camera lens of the personal electronic device is also described.

A lens selector for selectively exposing one camera lens and covering other camera lenses of a cell phone or the like is shown and described. The lens selector comprises a base which grips the cell phone and a lens cover movable between two or more positions. The lens cover may slide along the base when moving between positions. An arm resiliently biased into an engaged positions may lock the lens cover into a selected position on the base. The lens selector may substantially cover that side of the cell phone having lenses, and may grip edges of the cell phone. The lens selector may include a socket for centering an associated cell phone with respect to an optical device such as a spotting scope, so that the cell phone may capture images visible through the scope.

A method of increasing hydrophobicity of a molecular sieve is provided. The method includes: (a) providing a metallosilicate molecular sieve having a framework consisting of oxides of silicon (Si) and a metal (M), wherein M is boron or zinc; (b) contacting the metallosilicate molecular sieve with a liquid aqueous system, thereby obtaining a demetallated molecular sieve having silanol nests and empty framework sites; and (c) thermally treating the demetallated molecular sieve, thereby obtaining a thermally-treated molecular sieve, wherein the thermally-treated molecular sieve (i) retains the three-dimensional framework structure of the metallosilicate molecular sieve and (ii) has a higher Si/M molar ratio as compared to the metallosilicate molecular sieve.
