A nanowire battery uses nanowires to increase the surface area of one or both of its electrodes, which improves the capacity of the battery. Some designs (silicon, germanium and transition metal oxides ), variations of the lithium-ion battery have been announced, although none are commercially available.
In 2015, researchers in China used porous graphene as the material for a lithium-ion battery anode in order to increase the specific capacity and binding energy between lithium atoms at the anode. The properties of the battery can be tuned by applying strain. The binding energy increases as biaxial strain is applied. [24]
A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.
Verizon and other fiber-optic providers often package service in a bundle: internet, cable television and a telephone line for one low price. In some cases, oddly enough, you end up paying less ...
Mobile virtual network operators (MVNOs) in the United States lease wireless telephone and data service from the four major cellular carriers in the country—AT&T Mobility, Boost Mobile, T-Mobile US, and Verizon—and offer various levels of free and/or paid talk, text and data services to their customers.
Recent experiment on nanowire solar cells has led to a remarkable improvement of the power conversion efficiency of SiNW solar cells from <1% to >17% in the last few years. [5] The ability for lithium ions to intercalate into silicon structures renders various Si nanostructures of interest towards applications as anodes in Li-ion batteries ...
Verizon has confirmed that its cell service is back online following a massive outage affecting some of its mobile phone customers. “Verizon engineers have fully restored today’s network ...
BORSCHT functions: battery feed (B), over-voltage protection (O), ringing (R), signaling (S), coding (C), hybrid (H), and test (T) Loop start, ground start and E&M signalling; The pair of wires from the central office switch to a subscriber's home is called a subscriber loop.
