"They taught me a great deal about heroism in the face of grave material difficulties," Broun says.
Constraints in a real lab (wet-lab) setting include limited and out-dated laboratory equipment, unavailable materials and difficulties in demonstrating techniques due to large class sizes resulting in student crowding [ 3].
However, most of these methods involve more than one step, high energy requirement, low material conversions, difficulty in purification, and hazardous chemicals [13].
However, most of these methods normally involve a complicated and toxic lithography process that often results in high costs, material wastage, difficulty in patterning large areas, and a certain degree of environmental pollution.
Nevertheless, its inability for dissolving lipophilic drug active material and the difficulties in controlling the size and shape of the synthesized particles in nanometer range are critical drawbacks in its effective use.
However, these current structures that were made from concrete and metal are heavyweight materials that cause difficulties in handling during assembly, maintenance and reinstallation purposes.
We find that an integrated design approach in which both experiments and computational modeling are used has rarely been applied for these materials due to difficulties in relating insights gained on different length- and time-scales.
Study of M. genitalium genetic variation has been hampered by the limited availability of genetic materials due to difficulties in isolation and cultivation of this organism from clinical specimens.
