“…The greatest extensively used in biodiesel production are free lipases between the commercially available lipases from P. fluorescens (Lipase AsK, Amano), B. cepacia (Lipase PS, Amano), and T. lanuginosus (Lipase LA201 and Lipopan 50BG, Novozymes), and immobilized lipases from T. lanuginosus (Lipozyme TL IM, Novozymes) and R. miehei (Lipozyme RM IM, Novozymes) [ 651 , 652 ].…”

Lipases are very versatile enzymes, and produced the attention of the several industrial processes. Lipase can be achieved from several sources, animal, vegetable, and microbiological. The uses of microbial lipase market is estimated to be USD 425.0 Million in 2018 and it is projected to reach USD 590.2 Million by 2023, growing at a CAGR of 6.8% from 2018. Microbial lipases (EC 3.1.1.3) catalyze the hydrolysis of long chain triglycerides. The microbial origins of lipase enzymes are logically dynamic and proficient also have an extensive range of industrial uses with the manufacturing of altered molecules. The unique lipase (triacylglycerol acyl hydrolase) enzymes catalyzed the hydrolysis, esterification and alcoholysis reactions. Immobilization has made the use of microbial lipases accomplish its best performance and hence suitable for several reactions and need to enhance aroma to the immobilization processes. Immobilized enzymes depend on the immobilization technique and the carrier type. The choice of the carrier concerns usually the biocompatibility, chemical and thermal stability, and insolubility under reaction conditions, capability of easy rejuvenation and reusability, as well as cost proficiency. Bacillus spp., Achromobacter spp., Alcaligenes spp., Arthrobacter spp., Pseudomonos spp., of bacteria and Penicillium spp., Fusarium spp., Aspergillus spp., of fungi are screened large scale for lipase production. Lipases as multipurpose biological catalyst has given a favorable vision in meeting the needs for several industries such as biodiesel, foods and drinks, leather, textile, detergents, pharmaceuticals and medicals. This review represents a discussion on microbial sources of lipases, immobilization methods increased productivity at market profitability and reduce logistical liability on the environment and user.

“…Because inkjet uses low-viscosity liquids (≈10 centipoise or 10 −2 Pa s), the printed films tend to be thin, less than a micrometer in thickness. The ink formulations can be tuned to incorporate electronic materials; for example, semiconductors [119][120][121] and conductive electrodes [122][123][124][125] have been deposited by inkjet to fabricate circuits [126,127] as demonstrated in Figure 3c. [35] In addition, structural materials such as epoxy binders are commonly used in inkjet to build up 3D structures layer by layer.…”

simulation training, communication, and immersive entertainment. Yet, the utility of haptics is currently limited; moreover, it is challenging to produce the large-area, distributed signals required to mimic natural touch.It would be desirable for haptic actuators to generate large ranges of forces and displacements over short time scales, in a compact form factor in the case of wearable haptics. This dynamism is required because the structures such as the skin and elements of the musculoskeletal system are highly stretchable. Moreover, they are teeming with mechanosensory neurons that can perceive sub-micron surface features and macroscale displacements, with reaction times in milliseconds. [3,5] Thus, to accommodate this dynamism and sensitivity, an exceptionally versatile suite of materials and tools is required to realize the entire range of haptic perception.Haptic perception can be divided into two parts: the tactile and kinesthetic senses. [6][7][8] The tactile sense involves the nerve endings in the skin to detect contact, texture, and vibration. The kinesthetic sense is the awareness of the body position and involves structures located in the musculoskeletal system to sense force and motion. For example, to emulate the feeling of grasping a cup, a haptic system would need to trigger both tactile and kinesthetic senses. That is, pressure would be applied on the fingers to indicate contact, and other actuators located at the joints of the fingers would stiffen to produce resistance against moving into the space occupied by the cup. In comparison to visual or auditory inputs aiming at localized organs of eyes and ears, haptic systems require distributed inputs covering the body. The complexity involved to simulate haptic signals over large area, with sufficient spatial and temporal resolution and high dynamic range, has been a considerable challenge and thus presents exciting research opportunities.Conventional micro-electromechanical system (MEMS) has been used to implement vibrational feedback, which is the most common type of haptic effect in commercial devices today. However, fabrication techniques for MEMS are catered toward micrometer length scales and hence research is still needed to scale up MEMS assembly [9,10] for large, customized human interfaces. To realize many other promising haptic modalities, new materials and processing technologies are being explored to make devices that improve haptic realism and scalability for mass manufacturing.Haptic actuators generate touch sensations and provide realism and depth in human-machine interactions. A new generation of soft haptic interfaces is desired to produce the distributed signals over large areas that are required to mimic natural touch interactions. One promising approach is to combine the advantages of organic actuator materials and additive printing technologies. This powerful combination can lead to devices that are ergonomic, readily customizable, and economical for researchers to explore potential benefits and create new haptic applications...
