Next Gen Tablet Screens On Their Way?

Over recent years, graphene remains one of the most talked about materials, as experts believe it could revolutionise electronics production. Among the companies that are actively leading the development in this direction, Samsung is the one that seems to have achieved encouraging results.

In accordance with a report published by Samsung it seems that the technogiant knows to accelerate the commercialisation of graphene, and thus bring the ready products based on the neoteric material to the end customer… and it is supposedly about a ready prototype of the flexible tablet.

Samsung invention consists in ability to produce samples of graphene boards large enough to be used in the finished product. The company’s engineers in tight collaboration with side research groups claim they are now able to synthesise graphene on a semiconductor crystal and thus save all the useful properties.

Since Samsung is the pioneer manufacturer of smartphones with a curved display (Galaxy Round), the company’s desire to move ahead and create the first ever flexible device is absolutely unbridled. At the moment, the implementation is hardly possible because of the materials traditionally used in the manufacture of filling and housing: silicon and metal. Graphene boasts unique properties, unmatched flexibility, conductivity, transparency and extreme durability, so in theory it may become a perfect replacement for the outdated materials.

If there is a grain of truth in these announcements and Samsung is not trying to promote its novelties that hit the shelves the last month, the revolutionary devices can be expected to come off the assembly line in 3-5 years approximately.

Graphene Revolution Knocking At The Door

Graphene has acquired a status of one of the most advanced materials of our time due to its enormous potential and theoretical ability to change the way the electronic devices are produced. Until recently, the graphene manufacturing has been associated with certain difficulties. However, the South Korean technogiant, Samsung, assures it has managed to resolve the acute issue.

The results achieved by Samsung specialists in the field of graphene production herald the era of miniaturisation of electronics. This may sound implausible, but the industry has already been moving in the direction, where mobile phones are taking the thickness of a credit card.

Graphene represents the thinnest, most durable and most conductive material in the world at the moment. Discovered in 2004 in Manchester University by Russian immigrants Konstantin Novoselov and Andrey Geim, 2010 Nobel Prize winners in Physics, graphene can replace silicon which is massively used in chip manufacturing. However, the problem of utilising graphene has recently been associated with the need for a multilayer structure with boron nitride, which acts as an insulator. Samsung success in this direction means the imminent appearance of flexible touch screens and computers, lightweight aircraft, the finest HD-TV and superfast Internet.

Not only technological giants nourish interest in the neoteric material: there is a good number of graphene companies around the globe offering their services to introduce the brand-new technology in a business. Thus, such firms as 2-DTECH with the staff under 20 employees provide help savvy businessmen to employ graphene uses and benefit from the revolutionary material.

The ‘Side Effects’ Of Wind Power Approach

Wind, an inexhaustible source of clean energy, is becoming more widely used at strategic level, rapidly gaining public support at the same time. Wind power has been used since ancient Babylon (wetlands drainage), Egypt (grain grinding) and China and Manchuria (pumping water from the rice fields) times. In Europe, this technology was introduced in the XII century, while the adoption of truly modern approaches started only in the XX century.

Wind power can operate in areas with wind speeds above 4.5 m/s level. Wind power stations can either conduct their business within a network of an existing plant or represent a stand-alone construction. The so-called ‘wind farms’, the areas where a number of pieces of wind collection equipment is concentrated and functioning as an entire system, are also gaining momentum due to noteworthy economic feasibility.

The greatest share of wind energy production belongs to the United States and Europe (Denmark, Germany, Great Britain and the Netherlands in particular). For long years the US has been holding the leadership among the most powerful wind plants in the world, Roscoe Wind Farm, generating impressive 781 MW of power. Another interesting example is Aeolus II wind farm that operates at Wilhelmshaven, Germany and produces 7 million kw/h of energy annually, providing about 2 million of households with electricity. Currently, there are nearly 23,000 active turbines installed in the world.

The ins and outs

Despite the mass production, the cost of construction of a modern wind power is still far from being affordable. However, it should be fairly noted that its operation cost is almost negligible. Environmental and economic benefits largely depend on the correct location; it requires a detailed and comprehensive analysis of both technical, environmental as well as financial aspects. Wind energy meets all the conditions necessary for its identity as environmentally friendly method of energy production. Its main advantages are:

  1. No pollution – the production of energy from wind neither results in emissions of harmful substances into the atmosphere nor entails waste generation.
  2. Wind power is renewable, inexhaustible source of energy, allowing to save on fuel consumption, as well as on the process of its production and transportation.
  3. The area in the vicinity of a plant can be utilized for agricultural purposes with no restrictions.
  4. Stable costs per unit of energy is produced, plus the method contributes into the growth of economic competitiveness in comparison with conventional energy sources.
  5. The minimum transmission loss of energy – wind power plants can be built directly by the consumer, and in remote locations, which in the case of conventional energy require special connection.
  6. Easy maintenance, easy installation, low maintenance and operating costs.

Cheap to maintain

Once the tiresome process of manufacturing and installing is accomplished, the only thing the company has to take care of is to initial regular equipment checks. So who are these guys? Normally, farm owners either have in-house engineers or cooperate with seasoned providers, such as Granada Material Handling, offering a full array of wind turbine services as well as provides assistance with wind turbine inspections.

Industrial Flanges In A Nutshell

Flange is a device designed for seamless connection of pumps, pipes and valves. This connection method provides an easy way to modifying, cleaning or inspecting the system. Usually, the flanges come with welded or threaded connection; however, the market offers custom stainless steel flanges solutions as well – the firms like AlexanderComley produce both standard and custom-made flanges that meet virtually any requirements.

Flange mounting itself implies using bolts; impermeability is achieved due to gaskets. Industrial flanges are constructed from various materials: with processed surfaces in store, flanges are made from cast iron, stainless steel, brass, plastic, bronze and etc. In addition, flanges, just like pipes and fittings for special application, often have an internal coating of a different quality in comparison with external coating. According to AlexanderComley, bespoke flanges, tubesheet and butt weld fittings uk are oftentimes manufactured from the same material used in the production of pipes.

O-ring and gasket position depends on the implementation of surface and shape of the flange. The most commonly used types are as follows: surface with a projection; groove for the O-ring; flat surface; surface with internal and external thread and tongue and groove joints. It is important that the flange surface are characterised by minor roughness, to ensure the highest quality of the seal. The most widespread types of surface processing are roughing, spiral notching, concentric grooving and smoothing.

To provide the necessary tight flanged connection using gaskets is obligatory. An average gasket is a ring or pressured plates that used for water-resistant mounting. Gaskets are manufactured at extreme temperatures and pressures and are made of non-metallic, semi-metallic and metallic materials. The principle of operation is simple enough: a gasket is clamped between two flanges, and thereby fills the microscopic unevenness and the surface area to prevent leakage of gases and liquids.

Glass Reinforced Concrete: Guiding The Modern Architecture

Glass reinforced concrete represents a composite material consisting of fine-grained concrete (matrix) and dispersion reinforced with short glass fibers. Thus, glass reinforced concrete (or GRC) combines the typical of the conventional concrete high compressive strength with extreme flexibility and tensility (4-5 times higher than in concrete), strength (10-15 times higher) and frost resistance (more than 300 cycles).

This is an environmentally friendly material that does not contain harmful ingredients and belongs to the category of non-combustible materials. Glass reinforced concrete offers increased waterproofness and a high degree of adhesion to plain concrete, boasting high resistance to cracking at the same time. Easily molded, acquiring complex spatial shapes with GRC is a walk in the park mission, plus the material exactly replicates the tiniest details on the surface. Moreover, GRC products have a small cross-section (ranging from 6 to 20 mm) and are considerably lighter in comparison with the products of conventional concrete. Continue reading

Parking Ventilation: The Basics Of Design Explained

The growing demand of both industrial towns and large cities in carports, caused by the high population density in the urban areas, throw designers together with a good number of challenges. The main objectives set to car park ventilation professionals are typically the following:

  • Maintain the acceptable indoor air parameters
  • Ensure decent fire resistance
  • Implement an environment-friendly system

Covered parking facilities are usually located below the ground level and require the installation of mechanical ventilation in nine cases out of ten. Semi-covered parking constructions, as a rule, are comprised of frames with multiple floors, though a roof and exterior walls may be partially or completely absent. This is where a natural or mixed ventilation system can be installed (a combination of natural and mechanical systems can also be installed for sites with a large floor area).

Closed car park ventilation system performs the following functions:

  • Maintains the allowable concentration of carbon monoxide (CO)
  • prevents the formation of explosive concentrations of flammable gases

Parking ventilation

The main factor determining the characteristics of a future parking ventilation system is the approximate number of cars serviced on a daily basis. This number is oftentimes determined by the type of construction, which represents the carport. As a rule, apartment buildings and shopping centers adopt the condition of constant and distributed car use, while the number of moving vehicles varies from 3% to 5% of the total number of cars. The situation is different in parking lots of sports facilities, concert halls, airports and etc. Here, the number of vehicles in simultaneous motion equals 15-20% during peak hours or during the hours that coincide with the beginning or the end of the business day.

Involved In Geophysics: Professional Responsibilities

Depending on the specialization (exploration, seismology geophysics and etc.), a geophysicist is responsible for various tasks implementation. Thus, a geophysics specialist can conduct the business in a research laboratory equipped with all the bells and whistles as well as in the field, leaving the comfortable office for site exploration. Geophysicists typically visit deserts, mountains and other unusual and hard to reach places; sometimes they have no other choice but to climb the mountains or cross over wild rivers.

Geophysicists are involved in various natural deposits researches, ore, oil and gas exploration, seismic surveys and even borehole drilling. The arsenal of geophysicists includes myriads of tools for surveying with hydrographic, oceanographic, hydrological, meteorological and geophysical instruments among them. Additionally, due to geophysicists’ efforts the measurements of magnetic, electrical and gravitational fields are conducted. In accordance with the results retrieved they draw crustal structure maps, determine the thickness and composition of the ice sheets as well as the origin of rocks.

Geophysicists are also engaged in seismic studies of the Earth’s crust through artificial creation of explosion or seismic waves; the results are analyzed by computer and the appropriate forecasts are made.

In addition to general knowledge of physics and geography geophysics must be aware of geological and geophysical nuances. The specialists must know how to use professional software, plus they must be able to draw maps. In their work geophysicists apply engineering geology knowledge when it comes to dam , bridges, tunnels and large buildings construction.

No-Win No-Fee Investment Fund Shut Down

A far famed investment fund with a charging structure functioning under the ‘no win no fee’ principle was shut down as it fails to win over savers. Established in the first quarter of 2011 by Nigel Legge, a proficient and respectable stock picker, The Vinculum Global Equity faces its last days. An affair started by Legge collided with a major finance issue – the former Liontrust headman, the fund has managed to raise as little as 2.5m in euro. Therefore, an economically non-viable enterprise was subjected to a radical measure – shut down.

Three years ago, just when the fund was called into existence, financial experts spoke positively of the fee structure standing in fund service. Thus, Vinculum charged just 0.25pc annually, while a typical cost equaled 1pc per year for fund investments run by professional.

Additionally, Vinculum charged investors an extra of 20pc in case outperformance over stock is registered in comparison with the benchmark in the face of FTSE World Index. Legge explained the fees from a rational customer service point of view, saying that such action is way more reasonable rather than charging for underperformance. A savvy stock picker labeled the policy as a fund management evolution. Unfortunately, the evolution experienced a collapse as the fund contacts its investors, notifying of its closure.

The administrator of Vinculum, Peter Smith, in his letter to investors says that the fund is no longer economically viable, and the intention to shut down the fund is the only reasonable option available at the moment. Thus, February 10 was the day the fund stopped its functioning. It seems that Legge accepted the situation and make the decisive step to avoid possible financial accident claims.

The Benefits of Ultrasonic Cleaning in Distillery Industry

Distillery industry requires particularly close attention to the quality of the components for ​​spirituous beverages production, as well as the quality of glass containers in which they are bottled. The use of modern ultrasound technology allows achieving excellent results in containers cleaning that exceed any quality standards. Therefore, distillery companies can derive juicy benefits from using ultrasound equipment adjusted to particular demands.

Bottle washing machines allow solving one of the most crucial problems in distillery industry – inner surface of glass containers leaching under the influence of alcohol-containing product. This effect occurs because of poor quality glass surface, damaged by incorrect storage of container. Ultrasonic treatment of glass containers in a weak solution of hydrochloric acid at room temperature contributes to a full recovery of the glass surface, if the initial ratio of water resistance does not exceed 0.6 ml of 0.01 N HCl. The quality of the recovered surfaces is confirmed by storing alcoholic solutions for long periods of time under different climatic conditions.

Bottle washing machines – extra advantages

Bottle washing machines are also used for refillable containers cleaning. To remove the salt deposits in the bottle washing machines use acidic solutions, while removing a range of other contaminants implies using alkaline. Implanting ultrasonic cleaning in distillery manufactures contributes to a 100% increase in reusable packaging cleaning and a significant productivity growth.

Ultrasonic Cleaners can significantly intensify the process of extraction, resulting in rapid obtaining of high-quality extracts for the production of alcoholic beverages. An ultrasound effect on the extraction is achieved due to improved hydrodynamic conditions of the process and an increased temperature of the mixture. Another process optimization method lies in ultrasonic modules integration in existing equipment (percolators, extractors and tanks for infusion).

The process of ultrasonic cleaning is also used pharmaceutical, food and fertilizers production industries. Ultrasonic effect helps to retrieve various aqueous, alcoholic, oily solutions, crystalline substances, and thick dry extracts, syrups, pigments, aromatic solutions, disinfectants and etc.

Hilsonic is a shining example of an innovative company that focuses on providing ultrasonic cleaner of quality second to none. Drop in at to get acquainted with the price-list.
