متن کاملA piezoelectric micro generator worked at low frequency and high acceleration based on PZT and phosphor bronze bonding
Recently, piezoelectric energy harvesters (PEHs) have been paid a lot of attention by many researchers to convert mechanical energy into electrical and low level vibration. Currently, most of PEHs worked under high frequency and low level vibration. In this paper, we propose a micro cantilever generator based on the bonding of bulk PZT wafer and phosphor bronze, which is fabricated by MEMS tech...
متن کاملPatterned structure of remote phosphor for phosphor-converted white LEDs.
High efficiency white light-emitting diodes with superior color-mixing have been investigated. It is suggested that the patterned remote phosphor structure could improve the uniformity of angular-dependent correlated color temperature (CCT) and achieve high chromatic stability in wider operating current range, as compared to the conventional remote phosphor coating structure. In this experiment...
متن کاملA Greek Bronze Vase
When we think of Greek vases we generally have in mind Greek pottery, which has survived in quantity. Clay, one of the most perishable of materials, becomes one of the most indestructible in the firing. In fact, much of our knowledge of ancient civilizations is derived from the potsherds that are found in successive layers on ancient sites; a pot, once fired, may break into a hundred pieces, bu...
متن کاملNeolithic and Bronze Age
This document comprises a Stage 2 resource assessment and draft research agenda for the Neolithic and Bronze Age (Early – Middle) of the East Midlands. It builds upon the assessments for Derbyshire, Nottinghamshire, Lincolnshire, Leicestershire, Rutland and Northamptonshire presented at a seminar at County Hall, Leicester on 28.1.1999 (Bishop 1999; Chapman 1999, Clay 1999a; Membury 1999; Myers ...
