Bluesmuziek is springlevend

De bluesmuziek vormt de bakermat voor de populaire muziek van tegenwoordig. Vele hits van nu zijn met meer of minder moeite terug te voeren op originelen van jaren geleden. In die traditie breng ik “Blues in Einekoez” onder je aandacht.


Blues in Einekoez
Tijdens “Blues in Einekoez”, op 10 april 2015 in Einighausen treden twee bluesbands op, namelijk de Bluesdoctors uit Limburg en BIG YUYU van Mallorca. Dit vormt een goede aanleiding om eens in het rijke muziekarchief van de bluesmuziek te duiken; je kunt meeluisteren via een afspeellijst met YouTube-opnamen.*)

Checkin' Up on My Baby
Op het repertoire van de Bluesdoctors staat “Checkin' Up on My Baby”, een nummer waarin de harmonica een belangrijke rol speelt. De band maakt er een stevig, uptempo bluesrock-nummer van: http://youtu.be/q5YVuLWR6wM (live 2009).

Voor het origineel moeten we vele decennia terug: het werd in 1960 – mijn geboortejaar – opgenomen door de Amerikaanse blues-harmonicaspeler Sonny Boy Williamson II (1912-1965): http://youtu.be/mpyoeagugb0.

Het nummer is een van de kortste van de popmuziek, zelfs korter dan “Hit the Road Jack”, dat in datzelfde jaar werd geschreven door de r&b-artiest Percy Mayfield en dat bekend werd gemaakt door Ray Charles: http://youtu.be/0rEsVp5tiDQ (1961) - maar dat terzijde.

Checkin' Up on My Baby” werd onder meer opgenomen door John Mayall & The Bluesbreakers met Mick Taylor: http://youtu.be/Bdh_j6SFGdM (1967).

En door Mick Jagger, solo met Gary Moore (Moore Jagger): http://youtu.be/kWbHCdnW7yk (1992).

De versie waaraan ik de beste herinneringen heb is van Cuby & The Blizzards: http://youtu.be/yIzxYhSmJ34 (1968; live 1974, met Herman Brood op piano).

Een andere klassieker van Sonny Boy Williamson is “Help Me”: http://youtu.be/tXr6pS-79m8 (1963).

Ook dit nummer werd door Cuby & The Blizzards op een jazzy manier gecoverd: http://youtu.be/H94Noz89YPg (1969).

I Ain’t Superstitious
Een ander lied uit die tijd is “I Ain’t Superstitious” van de invloedrijke bluesartiest Willlie Dixon (1915-1992): http://youtu.be/kqRfCzNmrxY (1960).

Het werd bekendgemaakt door Howlin’ (Chester Burnett) Wolf (1910-1976): http://youtu.be/Rb8bzRZCGDY (1961).

Jeff Beck bezorgde er op het album “Truth” een eigenzinnige versie van: http://youtu.be/mQFdHlxMhZ0 (1968).

Willie Dixon heeft rond 1960 tal van bluesnummers geschreven die tot op heden door bekende bluesartiesten worden gespeeld. Een kleine greep: “Bring It All Home” van Canned Heat: http://youtu.be/1f2c0JHyPSg (live 1970).

Hoochie Coochie Man” van Muddy Waters: http://youtu.be/NV_ZhBcNiQQ (1954; live 1960).

I Just Want To Make Love To You” van Etta James: http://youtu.be/j4ErjX8p20s (1961).

Too Late” van Little Walter (Jacobs): http://youtu.be/DRJTJi7bi2Q (1953).

En “Wang Dang Doodle” van Koko Taylor: http://youtu.be/_w6IY0v-0pA (1965).

Reconsider Baby
Terug naar de Bluesdoctors: een ander klassiek nummer van deze band is "Reconsider Baby": http://youtu.be/Kd912OdHkPo (live 2009).

Dit nummer werd in 1954 uitgebracht door de Amerikaanse bluesgitarist Lowell Fulson: http://youtu.be/n7ZwNTbIqCk.

Het nummer werd bekendgemaakt door Elvis Presley: http://youtu.be/LmNXXUmP8W0 (1960).

Meer recent zijn de uitvoeringen van Robin Trower: http://youtu.be/_wp5TwEhx7o (1994).

En van Joe Bonamassa: http://youtu.be/YKs2QTBNYFY (2004).

Jonge bluesartiesten
Nou denk je misschien dat blues typisch iets is voor ouwe knarren. Maar wat denk je van de Amerikaanse bluesgitarist Eric Steckel die in 2007, amper 17 jaar, in het Italiaanse Pistoia het instrumentele nummer “Hide Away” op de bühne bracht: http://youtu.be/ouqc76q6Mpo.

Deze jonge artiest haakt daarmee aan bij de bluestraditie, want dit is een nummer van Freddie King (1934-1976) uit 1960: http://youtu.be/ua3s1W7XF-8.

Een ander bekend nummer van Freddie King is “Have You Ever Loved a Woman”: http://youtu.be/h-Zo7ijWlz0 (1960, bekendgemaakt door Eric Clapton).

Eric Steckel schrijft ook zelf nummers, zoals “Feels Like Home”: http://youtu.be/v6_vCJKgJQA (2008).

Of wat vind je van Eric Steckel’s leeftijdsgenoot Marquise Knox, die in de stijl van Albert King de klassieker “The Sky Is Crying” speelt: http://youtu.be/p0Ii5-uZXj4.

Dit is een klassieker van Elmore James (1918-1963), de King of the Slide Guitar, uit 1954: http://youtu.be/hKEdlSTHjtU.

Andere andere klassieker van Elmore James is “Look On Yonder Wall”: http://youtu.be/kVtclYVizx4 (1961).

En ook Marquise Knox schrijft zelf nummers, zoals “Can A Young Man Play The Blues?”: http://youtu.be/9mYy64SIFis (2011) - Ja, dus!

Real Bluesdoctors
Met het oog op “Blues in Einekoez” op 10 april 2015 blijven we dichtbij huis met de “Real Bluesdoctors”: http://youtu.be/FoRs-oH_gAs (live 2009).

46 Applications for smart materials

The goal of Startupbootcamp Smart Materials is to promote entrepreneurship (like it says) in the field of smart materials. Most definitions of 'smart materials' ignore its versatile application. Therefore, the example of 3M explains a lot.


In my February 9, 2015 blog post “The intelligence of a molecule” I gave ‘an answer’ to the question what smart materials are, based on the report “Advanced Materials”.

Another answer is found at 3M, a US company with $ 30 billion turnover, $ 4.6 billion net income, and 88,000 employees in 67 countries (2013). Until 2002, 3M’s full name was Minnesota Mining and Manufacturing Company (established 1902); the 3M Netherlands office is in Delft. 3M is the company behind many brands, such as Scotch (adhesive tape) and Post-it (memo sheets).

3M is a highly innovative company, where 37% of sales come from products introduced in the last five years (New Product Vitality Index, 2013). 3M cherishes an innovative culture that allows for instance that employees spend 15% of their time on projects of their own choice.

Unexpected combinations
3M product innovations fall within no less than 46 technology platforms. Following the example of Mendelejev’s Periodic Table of Elements, these are shown in a blocks schedule, see the picture. Therein, each technology – in analogy to the elements – is identified on the basis of a two-letter abbreviation.

The researchers from 3M are especially looking for innovations that arise when you combine two or more of those 46 areas. For example, the Microreplication process (Mr) – applying tiny, precisely shaped structures – is used for making sandpaper (Ab).

Inspiration for entrepreneurs
For anyone considering to register for Startupbootcamp Smart Materials, I’ve listed the 46 technology platforms of 3M.

The intelligence of a molecule

Startupbootcamp Smart Materials aims to promote entrepreneurship in the field of smart materials. Much is expected of such materials when it comes to functionality, energy use, and price. But what are they, smart materials?

 
Through Startupbootcamp Smart Materials ten selected entrepreneurs get access to money, mentors, office space, and a network of industrial partners to accelerate the development of their business. These entrepreneurs must be active in the field of smart materials; watch the trailer.

The report "Advanced Materials", a publication of the Dutch Ministry of Economic Affairs (2012), gives an answer to the question what is meant by smart materials.
"An answer," because there are many industrial application of materials. Examples that are mentioned in the report make clear what smart materials are.

For example, there is self-healing concrete that is mixed with bacteria.When cracks are formed in the concrete in which moisture penetrates, the bacteria become active. Their separation closes the cracks (Netherlands).

Also by adding capsules with epoxy (a polymer), self-healing concrete constructions are possible. When in this type of concrete cracks are formed, the capsules break and the epoxy will repair the damage (Singapore).

Cement can also be mixed with graphite particles, which function by their electrical conductivity as a sensor. This makes it possible to detect fractures, for example in buildings and underground infrastructure, such as sewers and tunnels (Singapore).

In self-healing coatings tiny capsules are often processed. If the coating is damaged, the microcapsules burst and a chemical reaction is triggered, which repairs the damage. Such intelligent coatings substantially reduce the costs of corrosion to aircrafts, machine parts, boats, and water treatment plants (Germany, Singapore, USA).

Much attention is paid to the extraction, recycling, and substitution of rare earth materials (neodymium, yttrium, europium, terbium, dysprosium, cerium, indium, lanthanum, and tellurium), which for instance are used in magnets, batteries, and high-tech devices (France, Japan, USA, Canada).

In membrane fuel cells the customary platinum (with its high and volatile price) has been replaced by (less expensive) polymer-based electrolytes (Israel).

Graphene is a unique material, because it is composed of a single layer of carbon atoms; it is one of the strongest materials in the world and it is a very fast semiconductor. There is now a battery with graphene that has a higher energy density and longer life than other lithium batteries. Rechargeable batteries with graphene can be recharged within minutes instead of hours. It is expected that graphene will also be used in semiconductors and flexible displays (South Korea, USA).

Carbon fiber reinforced polymers (composites) are light and super strong compared to steel. Therefore, this material is increasingly used, for example in cars: a composite seat is 23 percent lighter than the current steel seat. The main factor is the lower fuel consumption, but there are other reasons to use composites: improved driving characteristics, corrosion resistance, recyclability, and multifunctional and aesthetic properties. You will also find composites in aircrafts, the blades of windmills, bridges and road bike frames. Aircraft engines with composites can be made 225 kg lighter, which reduces fuel consumption by fifteen percent. Instead of composites, magnesium or titanium can be used (Japan, Germany, the Netherlands, France, USA).

Piezoelectric crystals can convert mechanical energy into electrical energy. Generators with such crystals can be placed in asphalt to feed street lighting, traffic lights and signs (Israel).

There is a thin, flexible, foldable, and water-resistant lighting system that can be printed on fabric, leather and vinyl. The product does not produce heat, it is energy efficient and requires no external light source as is the case for reflective materials. The material is now used in keyboards of mobile phones, but can also be applied in sport and safety clothing (USA).

The super-strong Dyneema fiber of DSM (located at Brightlands Chemelot Campus) can be used in clothing (sport and leisure), protective equipment (vests) and super-strong ropes (replacing heavy steel cables or chains for offshore and cranes; Netherlands, USA).

'Vitrimère' combines the properties of rubber and glass: insoluble in water, stretchable, flexible or rigid depending on the composition, but very strong, reformable when heated, and it can be recycled. This polymer is very useful to make a complex casting mold; watch the demo (France).

A new type of double glazing is three times thinner than normal double glazing and insulates two times better. Thanks to the coating on these intelligent windows it is possible to darken the window by simply pressing a button (Germany).

Glass in solar cells can be replaced by material that is less fragile, lighter and more flexible (Israel).

Zeolite beads (a type of mineral) are suitable for heat storage. These porous spheres absorb heat when they come in contact with warm, dry air, and release this heat when they come into contact with water (Germany).

By adjusting the feed of the silkworm, functionalities can be added to the silk. Silk can be easily colored by adding dyes to silkworm feed. More advanced applications can be found in the life sciences, such as silk suture and carrier material for tissue regeneration (Singapore).

A familiar example of biomimicry – simulating solutions that occur in nature – is the superhydrophobic coating, based on the leaf of the lotus flower. Water and dust literally roll off this self-cleaning coating. Such coating is still a relatively low-tech application of superhydrofobicity. More high-tech is the use in so-called. ‘lab-on-a-chip’ microfluidic devices, in which it is important to transport small quantities of liquid in a controlled way (China).

Black butterfly wings reflect little sunlight and thereby absorb a large part of the energy. Those wings are made of elongated rectangular scales; similar to roof tiles. This structure was copied to titanium dioxide with a similar structure; with this material water molecules could efficiently be converted into oxygen and hydrogen (China).

On textiles and plastic materials titanium dioxide particles can be applied. These TiO2 particles can provide unique properties, such as color fastness, self-cleaning ability or resistance to bacteria (Netherlands).

Large displays based on organic LEDs are under development, which are very thin and lightweight, with very low power consumption, fast response, and wide viewing angle (Japan).

In power station systems, power transmission networks, electric cars, railways and domestic appliances so-called converters are used. By replacing the silicon in these convertors by silicon carbide energy savings can be realized, while higher electrical currents can be processed and the converters can be made more compact (Japan).

There are supramolecular structures in the form of a capsule, which are about a nanometer in size (one billionth of a meter). Other molecules can be introduced into the cavity. Such capsules can be used for targeted drug delivery. For example, medications can be safely guided through the stomach, to be released from the capsule into the duodenum (Japan).

The color of electro chromogenic materials is 'switchable', which makes them suitable for 'electronic paper', i.e., the black and white displays of e-readers. E-paper reflects light like a newspaper and can be read in daylight. Since these screens emit no light, the eye becomes less tired compared with conventional screens. Moreover, the image of an e-paper screen is not constantly refreshed and does not disappear when the power is turned off. E-paper thus saves energy (Japan).

Viscosity is a physical property of a material: as the temperature rises, the viscosity of a liquid decreases. For many applications viscosity changes are too small, too slow or too complex. Noteworthy is the development of shock absorbers, which can be adapted to the driving conditions: an electric current affects the viscosity of the fluid in the shock absorber (China).

Shape-memory materials can return from a deformed (temporary) state back into one or more original forms. These materials do this based on external stimuli, such as temperature change or light. There are labels of shape-memory polymers that can be used to check the authenticity of a product. After heating the label the embossed characters become permanently visible. Such a label could contribute to the fight against counterfeit products (China).

Dear entrepreneur, please surprise us with your application of smart materials.

Requiem voor een boekwinkel

In tijden dat het online winkelen voor steeds meer mensen normaal wordt, heeft de detailhandel het maar moeilijk. Je ziet het aan de leegstand in sommige binnensteden. Zo ook de boekwinkel in dit fictieve verhaal.


De bel van de voordeur ging. Piet legde zijn boek aan de kant en begaf zich naar de voordeur. Hij vroeg zich af wie dat kon zijn, want hij verwachtte geen bezoek.

* * *

Piet was niet meer de jongste, maar voor hem gold: je bent zo oud als je je voelt. En hij voelde zich nog jong van geest. Toch was er iets gebeurd waardoor hij dat eigenlijk moeilijk kon volhouden. Jarenlang had hij namelijk een boekwinkel gedreven in een kleine provinciestad.

Hij was er als jongeman gaan werken. Eerst als bediende, vooral het afrekenen van boeken en tijdschriften. Maar hij las veel en kon zijn klanten dan ook goed adviseren. Hij wist al gauw welke boeken zij niet mochten missen. Zo hielp hij mee om de klantenkring van de winkel te vergroten. Hij kreeg van zijn baas steeds meer verantwoordelijkheden.

Twaalf jaar nadat hij er in dienst was getreden kreeg hij de kans om de zaak over te nemen. Een kans die hij niet voorbij liet gaan, want de boekwinkel was zijn lust en zijn leven.

Daarna kwam de online handel op gang en daar had Piet steeds meer last van. Hij deed al het mogelijke om zijn klantenkring vast te houden. Hij moderniseerde de winkelinrichting, hij organiseerde lezingen en signeersessies met bekende schrijvers en hij richtte zelfs zijn eigen webwinkel in.

Maar wat hij ook deed, het bracht niet meer dan uitstel van executie. Hij kon zijn boekhandel niet langer overeind houden. Tegen Amazon en Bol kon hij niet op.

* * *

Pas geleden heeft Piet de boekwinkel definitief op slot gedaan. Er was geen droog brood meer in te verdienen.

En toen zat hij thuis. Jong van geest, maar vrijwel kansloos op de arbeidsmarkt.

* * *

Piet opende de deur en voor hem stond een montere jongeman in een fris PostNL-uniform. Half op het trottoir stond zijn bestelbusje geparkeerd met de schuifdeur wagenwijd open, halfvol pakketjes die vandaag nog moesten worden afgeleverd.

De jongeman zei: “Ik heb een pakketje voor uw buren, maar daar is niemand thuis. Zou u dit voor hen in ontvangst willen nemen.” Zonder veel enthousiasme nam Piet het pakketje over.

Een paar uur later kwam Frank, Piet’s buurman thuis. Piet pakte het pakketje van het tafeltje bij de voordeur en belde bij Frank aan. Die deed snel open, de jas nog in de hand: “Hoi, Piet. Oh, je hebt een pakketje voor mij. Ah, ik zie het al: de nieuwste roman van Grunberg. Gisteren besteld, vandaag bezorgd. Dank je wel.”

Piet slofte terug naar huis. Hij had ooit tientallen, misschien wel honderden romans van Grunberg verkocht. Nu was hij het meewerkend orgaan geworden van een webwinkel die zijn handel kapot had gemaakt.

Hij voelde zich opeens heel oud.

* * *

Volgens het Centraal Bureau voor de Statistiek daalde het aantal boekwinkels tussen 2011 en 2014 van 605 naar 550 verkooppunten; in 2000 waren er nog 1400 boekhandels.
