MEMS Fabrication: Enabler of growth or Barrier to the Industry?

The utter variety and varying necessities of MEMS devices and the one creation, one procedure approaches are the source of most MEMS fabrication trials. While a sole method will not suit all businesses, forming an ecosystem leveraging different companies’ expertise is perhaps the best way to address these challenges. Though, joining together this system is difficult since it has many partners in the mix only works if the whole supply chain follows basic design rules and a common highest tech expansion roadmap.

Since starting these commonalities needs effort, numerous medium and large companies prefer to own their supply chain, irrespective of the costs. In contrast, developing companies that cannot support heavy investments for new equipment will unavoidably find foundries that have all the apparatus in place, along with a varied diversity of MEMS processes, a more striking option. As you embark on a MEMS fabrication journey, which choices should you deliberate to have their noses in front?

Finding ecosystem partners

Since there are a number of different technology selections that make process integration challenging in MEMS fabrication, technical expertise is the key to evolving unique products in time. If you can’t have your supply chain, it is better to find partners whose know-how matches and foils your technology.

Own Supply Chain

There are many benefits of owning the whole supply chain, all the expertise will be inside the company, IP is fairly easy to protect, and managing the supply chain is simpler. Though, this model requires significant funding in tools and, ultimately, considerable effort and finances to remain technically competitive in every part of the supply chain.

Outsourcing of the ASIC

You may choose a fully possessed supply chain, subcontracting only ASIC fabrication and perhaps ASIC enterprise and assembly. This option needs momentous know-how in MEMS technology, liberating you from the limits of a fabless working model as there is more control of MEMS fabrication procedures. It also offers further IP defense than what you will have with a foundry. The process of outsourcing will curtail the procedure flow and decrease the total capital needed.

Foundry Models

While most companies still have their own supply chain or farm out the ASIC portion of their instrument than make use of MEMS foundries, MEMS foundry solution is especially good for the companies, more concerned about cost. If you can’t afford the considerable investment required for novel tools and cutting-edge materials or the product needs fast scaling-up for the reason of having short lifecycles, foundry solutions should be considered.

There are two key types, pure-play foundries and one with design services and its own IP. Pure-Play foundries are an excellent choice for a MEMS design-based company not having its fabrication line. Though, if your company lacks detailed knowledge of MEMS design, the other kind of foundry will give you design support and perhaps some IP too.

Because of these benefits of humic acid, the humic acid market is predicted to advance at a considerable pace in the coming years. The acid is dark brown in color and is extracted from coal sediments or soil upon reaction with different reagents and chemicals. Different applications areas of this acid are seed, foliar, and soil. Out of these, humic acid was utilized the most for the foliar application in the past, as it is being utilized extensively in several concentrations and physical forms by either directly adding it to the soil or by spraying.

The acid can be used for different crop types namely turf and ornamentals, row crops, and fruits and vegetables. The largest demand for humic acid in the past was created for row crops, due to the surging scarcity for food globally. When the geographic scenario is taken into consideration, the European region emerged as the largest humic acid market in the past, which is ascribed to the early adoption of humic acid and rising penetration of organic farming in countries including the U.K., Germany, Spain, France, and Italy. Other than this, the adoption of humic acid is also projected to increase significantly in North America in the coming years, owing to its superior performance and advanced properties.

Apart from the degrading quality of soil, the scarcity of food around the world is also a major reason for the adoption of humic acid. The population globally is growing rapidly, which is why the agricultural organizations are aiming at increasing the crop yield and quality. In this case, the utilization of humic acid has resulted in positive outcomes and enhanced plant growth by improving different plant mechanisms, including cell respiration, enzyme activities, protein synthesis, photosynthesis, and water and nutrients uptake.

Hence, the demand for humic acid is rising because of the rapid soil degradation and growing scarcity of food.

What are Printing Inks?

Printing inks include three components such as the vehicle, the coloring ingredients, and the additives. The vehicle enables the transferring of the coloring ingredient from the ink fountain to the Typeform, usually a vegetable base such as rosin, wood oils, or linseed. It dries by oxidation or penetration and ensures fixation at the same time. It is a solvent base derived from kerosene that involves case drying through evaporation.

For more insights:- https://www.psmarketresearch.com/market-analysis/printing-ink-market

The coloring ingredients come in various forms, such as fine pigments, solid particles manufactured from chemicals, highly insoluble in water, or less soluble in solvents.

The coloring agents made from chemicals are soluble in water and in solvents such as lacquers obtained from fixing a coloring agent on powdered aluminum.

The additives help in stabilizing the mixture and provide additional desirable characteristics to the ink. The nature and proportion of additives vary relying on the printing process and the material to be used. The proportions need to be checked and modified when required during printing.

Offset and letterpress utilize greasy inks. These thick greasy inks are used on sheet-fed presses for printing. In such printing, vehicles are usually made of vegetable oils with contents of synthetic or hard natural resins dispersed in mineral oils.

The black color is generated from the incomplete combustion of natural gas or oils, which results in forming the organic pigment, carbon black.

The colored pigments are usually the inorganic compounds of molybdenum, chromium, iron, and cadmium. The chromium provides the yellow, orange, and green colors. While molybdenum provides orange color, cadmium gives red and yellow color, and iron gives blue color.

Offset inks are more colored compared to letterpress inks, as they are required to be transferred to a blanket before they reach paper. Moreover, pigments should be prevented from being picked by the water from the dampening system.

There are links for both offset and letterpress, which come with special qualities. The vehicle is not homogenous in high-gloss inks as it is with ordinary inks. It is heterogenous in nature, relying on synthetic resins dissolved in the solvent, including lead and cobalt additives. The ink glazes as it gets dried.

It involves a series of operations to be finished during the printing of several colors, as the ink has time to dry, it can get attached to the surface.

Quick-setting inks require a vehicle with a base of resins dissolved in a quick-drying solvent. Heat-set inks need heat application to provide both oxidation process and solvent evaporation, along with penetration of several elements rendering the ink with more fluid.

The moisture set inks to get fixed by applying directly to damp paper or exposing them to water spray after their application to dry paper.

The metallic inks contain bronze, powdered copper, gold mixed, or aluminum mixed with the pigment, such as magnetic inks which contain powdered magnetized iron mixed with the pigment to determine the shape of the printed characters.

The demand for printing inks is projected to rise due to the expansion of the packaging industry and advent of the advanced technology.

Types of Television Documentary

For more insights:- https://www.psmarketresearch.com/market-analysis/documentary-television-market

Documentaries are shown on television in a production known as a television documentary. There are two types of television documentaries: television documentary films and television documentary series. Television documentaries can be viewed as a single documentary to be aired on a news- or documentary-related channel. Sometimes, documentaries that were originally created for television may be shown in a theatre.

The production companies' adaptation of the design and concept for documentary production to current affairs and real-time occurrences is also predicted to support television documentary market growth in the coming years. Additionally, the pandemic COVID-19 epidemic has increased the number of people watching various documentaries globally, which has favorably influenced television documentaries.

People of various racial and ethnic backgrounds have started to express interest in TV programs with cultural material as self-identity has become more and more of a hot topic. The focus of documentary producers is also being drawn to this, and they are beginning to get more involved in such subgenres of documentaries. White, Latino, Asian, and Black are the main racial groups covered in racial films. There are many categories of documentary films which are:

• Expository Documentary

The term "documentaries" most closely resembles expository documentaries. Expository documentaries differ from poetic documentaries in that they aim to convince or inform. It lacks any ambiguous or poetic eloquence. This format combines Ken Burns with television.

• Observational Documentary

Observational documentaries concentrate on observing the outside environment. It first appeared in the 1960s with the development of portable film tools and equipment. By allowing the audience to explore the subject's most significant and occasionally most private moment, they were able to convey nearly all aspects of a problem.

• Participatory Documentary

Participatory shares traits with observational and expository writing. They integrate the storyteller into the film. The voice of the filmmaker can be heard asking the interviewees a variety of questions from behind the camera. Thus, the filmmaker has a direct effect on the stories' essential functions.

• Reflexive Documentary

Participatory documentaries and reflective documentaries are similar in that both include the filmmaker as an integral element of the final product. Contrary to interactive documentaries, they don't try to look into a different topic. Their purpose is primarily to attention to themselves.

• Performative Documentary

It is a distinctive and original blend of styles utilized to convey a moving message to the world and to place emphasis on practical topics. They frequently include intimate human stories and experiences alongside enormous historical and political themes. This is also known as the "Michael Moore" approach since he frequently used his own experiences to illustrate how society produces reality.

• Poetic Documentary

In the 1920s, poetic documentaries made their debut. Their primary goal is to emphasize imagery, and experience, and show people the globe from a variety of perspectives. They mostly portray an emotion rather than reality and are loose and abstract. Its shape is experimental and idiosyncratic.
