The selection of solvent for preparing a working electrode (and to act as the electrolyte) is known to influence the

efficiency of dye-sensitized solar cells. In this topical review, results taken from a systematic study are presented from

the authors’ own lab examining how protic and aprotic solvents, as well as solvent polarity, a…[더 보기]

Many cell types will grow when attached to a rigid surface but not in suspension, a phenomenon termed „anchorage dependence”︁. Anchorage dependence can be studied

by incorporating solid particles of varying size into gels. It has been found that colonies will form on glass fibrils 500 μ

in length, but not in the presence of silica fragme…[더 보기]

Clay brick has been a standard building material for thousands of years, used both for building walls and as paving

surfaces for roads, pathways, and courtyards. There is nothing more elegant than a driveway, walkway, or patio paved with

brick. Although concrete pavers are somewhat harder and more durable than clay brick, classic brick…[더 보기]

Abrasive-cutting processes are widely used to obtain semi-finished products from metal bars, slabs, or tubes. Thus, the

abrasive cutting-off process is applied when requiring precision cutting and productivity at a moderate price. Cut-off tools

are discs composed of small abrasive particles embedded in a

bonding material, called the…[더 보기]

Mounting a TV is a great way to free up space in your

living room. If you’ve got kids who get touchy with electronics that they shouldn’t be putting their hands on, an out-of-

home decor. It’s aesthetically pleas…[더 보기]

General equipment makes up a lab’s foundation. Without these crucial tools, few experiments could be performed, because

nearly every research project depends on one or more of such technologies. As fundamental elements of research, general lab

equipment must also be efficient. “Energy efficiency in laboratory equipment is extremely imp…[더 보기]
