Latest Patents.

One of Hasan’s latest inventions concerns eco-friendly membranes for separations. The method uses a polymer dope solution containing dimethyl sulfoxide (DMSO) and one or more deep eutectic solvents (DES) to produce a porous membrane. For a polylactic acid (PLA) membrane, non-solvent induced phase separation can be used. The DES concentration may range from about 0.5 to 3.0 weight percent, helping increase membrane porosity and average pore size. An example uses choline chloride and ethylene glycol, and the membrane can be applied to oil-water separation with oil rejection of at least 80 percent.

Another invention describes a low-voltage reduced graphene oxide (rGO)-based biosensor. The method applies an analyte to a sensor configured to bind it, then uses a small direct-current voltage and monitors the resulting electrical signal. The specified voltage range depends on the analyte’s charge: +0.0008 to +0.005 volts for negatively charged analytes, or −0.005 to −0.0008 volts for positively charged analytes.
