Potential application of the high aspect ratio cryogenic SF6/O2 plasma ething process for developing trench based inertial micromechanical devices with capacitive sensing, is investigated and demonstrated. An ICtechnology compatible process flow involving anodic bonding of silicon to glass and plasma etching as a single post processing step is identified. It involves a novel method for front-to...

cementation of alloy-based restorations with traditional cements (e.g., glass-ionomer, resin-modified glass-ionomer, zinc phosphate, zinc polycarboxylate) to bonding of all ceramic restorations with resin based cements. With the increasing demand for high-end esthetic treatments for anterior teeth restorations, the need for a good esthetic cementation system comes into play in modern day dentis...

Adherent mammalian cells dynamically interact with their extracellular matrix (ECM) and culture substrate. To accommodate this sensitivity, standard culture techniques typically utilize tissue culture polystyrene (TCPS), a treated polystyrene substrate that promotes cell attachment. However, TCPS cannot be easily integrated into microfluidic devices as it is incompatible with conventional fabri...

Organosilane-functionalized carbon dots (SiC-dots) were prepared by a simple one-pot hydrothermal approach. The photoluminescence (PL) properties of the SiC-dots revealed a reversible response toward the temperature (293-343 K). Through Si-O-Si bonding, temperature-sensitive PL SiC-dot films could be easily fabricated on glass substrates.

Mexylaminotriazine derivatives form molecular glasses with outstanding glass-forming ability (GFA), high resistance to crystallization (glass kinetic stability, GS), and a glass transition temperature (Tg) above room temperature that can be conveniently modulated by selection of the headgroup and ancillary groups. A common feature of all these compounds is their secondary amino linkers, suggest...

The bonding arrangement in amorphous materials plays a dominant role in determining their electrochemical, optical and transport properties. However, it remains a challenge to manipulate amorphous structures in a controlled manner. Recently, scientists at the Molecular Foundry at Lawrence Berkeley National Laboratory (LBNL) developed synthetic protocols for incorporating well-defined nanocrysta...

INTRODUCTION This article presents a 6-month case report and an in vitro evaluation of the performance of the new self-etching glass-ceramic monobond etch and prime (MEP) when applied in a lithium disilicate (LD). The MEP contains in the same bottle, along with acid conditioner and silanes. This simplifies the bonding procedures by reducing not only the number of steps, but also the working tim...

Polysilicon thick films have been found to be an irreplaceable option in various sensors and other microelectromechanical system (MEMS)-designs. Polysilicon is also a prospective option for replacing singlecrystal silicon in customized silicon-on-insulator-substrates. Due to the nature of polysilicon, bonding for MEMS-purposes has so far concentrated on anodic bonding, which has drawbacks for i...

The problem of improving the delamination resistance and toughness of laminate fiberreinforced composites especially for the drop-off structure is receiving considerable attention with the increasing need and application in industries. A hot melt-bonding process is developed to bond glass fabric laminates and the thermoplastic (TP) polysulfone (PSU) interleaf prior to the vacuum assisted resin ...

Developing an accurate model for MEMS devices and structures is a great asset for future design optimization and provides insight into experimental results. A thermal conductivity pressure sensor was microfabricated to evaluate the success of a glass frit vacuum packaging scheme. The sensor and the package dimensions present classical size effects that must be included in the model for accuracy...
