Tensile failure properties of single collagen fibrils were determined using our original tensile test method. Fibrils were directly isolated from the fascicles of mouse tail tendons. Both the ends of each fibril were wound onto the tips of two microneedles several times using micromanipulators. The fibril and tips were immersed in physiological saline solution. Then, the fibril was stretched to...

decade, [ 15 ] beginning with the use of fi bers as mounting structures [ 16–19 ] and progressing onto the use of scanning probe microscopy (SPM) tips. [ 6,8,13,20,21 ] While mounting nanoparticles onto SPM tips is more diffi cult than with fi bers the additional capabilities of the SPM tip have made such tips desirable. However , these tips typically require complicated assembly processes to p...

We report a plasmon-assisted growth of metal and semiconductor onto the tips of Ag nanotriangles (AgNTs) under light irradiation. The site-selective growth of Ag onto AgNTs are firstly demonstrated on the copper grids and amine-coated glass slides. As the irradiation time increases, microscopic images indicate that AgNTs gradually touch with each other and finally "weld" tip-to-tip together int...

Structural variations (SVs) in a genome are now known as a prominent and important type of genetic variation. Among all types of SVs, the identification of transposon insertion polymorphisms (TIPs) is more challenging due to the highly repetitive nature of transposon sequences. We developed a computational method, TIP-finder, to identify TIPs through analysis of next generation personal genome ...

Atomic force microscopy (AFM) is a powerful tool for studying tribology (adhesion, friction, and lubrication) at the nanoscale and is emerging as a critical tool for nanomanufacturing. However, nanoscale wear is a key limitation of conventional AFM probes that are made of silicon and silicon nitride (SiNx). Here we present a method for systematically quantifying tip wear, which consists of sequ...

Introduction Transjugular intrahepatic portosystemic shunt (TIPS) is a non selective portosystemic derivation created by endovascular techniques. A transhepatic comunication between one of the hepatic veins and a branch of portal vein is created using a needle system. Intrahepatic trajectory remains open by placing a metallic stent. TIPS is an effective method to relieve the portal system press...

The authors have developed an ultrahigh vacuum (UHV) variable-temperature four-tip scanning tunneling microscope (STM), operating from room temperature down to 7 K, combined with a scanning electron microscope (SEM). Four STM tips are mechanically and electrically independent and capable of positioning in arbitrary configurations in nanometer precision. An integrated controller system for both ...

The present study demonstrates the potential of nutrient-alginate encapsulation of shoot tips of sunflower, Helianthus annuus (hyb. Azargol) for synthetic seed technology, which could be useful in germplasm distribution and exchange. Shoot tips from in vitro shoot cultures derived from mature seed explants were encapsulated in 3% sodium alginate and 100 mM CaCl2. 2H...

Cryopreservation has been recognized as a practical and efficient tool for long-term storage of vegetatively propagated plants. This study was conducted to investigate the effects of sucrose concentration, hardening temperature and different cryopreservation methods on the survival rate of potato shoot tips after cryopreservation. Excised shoot tips of in vitro plantlets of potato cultivars, At...

We fabricated triisopropylsilyl (TIPS) pentacene organic thin-film transistors (OTFTs) by inkjet printing method and investigated their electrical properties. The film morphology of TIPS pentacene layer and the field-effect mobility of OTFTs were greatly affected by choice of the solvent which TIPS pentacene was dissolved in. Especially the boiling point of a solvent was a critical factor that ...
