Levansucrase is responsible for levan formation during sucrose fermentation of Zymomonas mobilis, and this decreases the efficiency of ethanol production. As thiol modifying agents decrease levan formation, a role for cysteine residues in levansucrase activity has been examined using derivatives of Z. mobilis levansucrase that carry serine substitutions of(More)
Micromachining is the most basic technology for the production of miniaturized parts and components. Micro turning is one type of micromachining process which uses a solid tool and its material removal process is almost similar to conventional turning operation. The objective of this paper is to provide a state of the art in the field of micro turning. In(More)
High performance of organic tandem solar cell is largely dependent on transparent and conductive intermediate layer (IML). The current work reports the design and fabrication of an IML using a simple solution process. The efficiency of a homo-tandem device with poly(3-hexylthiophene):phenyl-C61-butyric acid methyl ester as an active layer and(More)
Monolayer molybdenum disulfide (MoS2) is an emerging two-dimensional material beyond graphene, which could potentially be applicable to lightweight, flexible optoelectronic device. In this study, we have demonstrated a planar metal-semiconductor-metal (MSM) photodetectors based on large area monolayer MoS2. The monolayer MoS2 was grown via chemical vapor(More)
Negative Bias Temperature Instability is an important lifetime reliability problem in microprocessors. SRAM-based structures within the processor are especially susceptible to NBTI since one of the PMOS devices in the memory cell always has an input of „0‟. Previously proposed recovery techniques for SRAM cells aim to balance the degradation of the two PMOS(More)
This paper proposes a new Hybrid Particle Swarm Optimization (HPSO) algorithm that integrates the features of Evolutionary Programming (EP) and Particle Swarm Optimization (PSO) to solve the Profit Based Unit Commitment (PBUC) problem in deregulated power market with emission limitations. The twin objective optimization problem is formulated to maximize the(More)
