Impact of Machine Breakdowns on Productivity
This paper reports the machine breakdowns and their impact on the total productivity for the FMCGs (Fast Moving Consumer Goods) industry because higher productivity rate is important factor on which the customer services largely depend in this competitive business world. This paper also suggests that the machine breakdowns and other related problems within the plant are due to improper care, keeping the plant operative for twenty four hours a day, seven days a week without any break and lack of management\'s concentration towards these issues. These break-downs results in un-timely closure of the plant and very poor production performance is achieved in the plant that affects the service level at great level. Realising the importance of maintenance in improving productivity and service, an attempt has been made in this paper to study the scope of maintenance with the help of a case study

A Novel Activated-Charcoal-Doped Multiwalled Carbon Nanotube Hybrid for Quasi-Solid-State Dye-Sensitized Solar Cell Outperforming Pt Electrode
Highly
conductive mesoporous carbon structures based on multiwalled carbon
nanotubes (MWCNTs) and activated charcoal (AC) were synthesized by
an enzymatic dispersion method. The synthesized carbon configuration
consists of synchronized structures of highly conductive MWCNT and
porous activated charcoal morphology. The proposed carbon structure
was used as counter electrode (CE) for quasi-solid-state dye-sensitized
solar cells (DSSCs). The AC-doped MWCNT hybrid showed much enhanced
electrocatalytic activity (ECA) toward polymer gel electrolyte and
revealed a charge transfer resistance (<i>R</i><sub>CT</sub>) of 0.60 Ω, demonstrating a fast electron transport mechanism.
The exceptional electrocatalytic activity and high conductivity of
the AC-doped MWCNT hybrid CE are associated with its synchronized
features of high surface area and electronic conductivity, which produces
higher interfacial reaction with the quasi-solid electrolyte. Morphological
studies confirm the forms of amorphous and conductive 3D carbon structure
with high density of CNT colloid. The excessive oxygen surface groups
and defect-rich structure can entrap an excessive volume of quasi-solid
electrolyte and locate multiple sites for iodide/triiodide catalytic
reaction. The resultant D719 DSSC composed of this novel hybrid CE
fabricated with polymer gel electrolyte demonstrated an efficiency
of 10.05% with a high fill factor (83%), outperforming the Pt electrode.
Such facile synthesis of CE together with low cost and sustainability
supports the proposed DSSCs’ structure to stand out as an efficient
next-generation photovoltaic device
