Here we describe a novel approach to generate monodisperse silicone microdroplets via microfluidic based microemulsion. Through a flow-focusing configuration, a continuous flow of commercially available silicone precursor solution has been successfully dispersed into discrete microdroplets with narrow size distribution, which are future solidified into stable microparticles by subsequent therma...
Figure 1: Raw data with calculation Differential Scanning Calorimetry (DSC) is used to measure heat flow into or out of a sample as it is exposed to a controlled thermal profile. DSC provides both qualitative and quantitative information about material transitions such as the glass transition, crystallization, curing, melting, and decomposition. For some of these transitions, DSC can provide no...
Although surgical resection is the primary means of curing both primary and metastatic lung cancers, about 80% of lung cancers cannot be removed by surgery. As most patients with unresectable lung cancer receive only limited benefits from traditional radiotherapy and chemotherapy, many new local treatment methods have emerged, including local ablation therapy. The Minimally Invasive and Compreh...
As new synthetic, low-loss polymers are developed, polymer optical cavities are experiencing a revolution, in both fabrication design and functionality. Recently, a fabrication technique was developed that enabled planar arrays of polymeric resonators to achieve cavity Q factors greater than 1 million. In the present letter, this molding technique is expanded to fabricate resonators from polyme...
Alkali-resistant hot-curing epoxy binders based on ED-20 and new amine hardeners “Amikrost” have been developed, intended for the production of glass-composite fittings construction purposes. The rheological properties compositions were determined, using differential scanning calorimetry thermogravimetric analysis, temperature dynamics curing process thermal-oxidative resistance cured samples s...
The temperature distribution in human body regulates variety of biological mechanism. Human Skin is a very complex structure and abnormality in temperature of various layer of skin play important role for curing and treatment diseases like tumor, cancer etc. The eight layers of human skin namely stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, stratum germinativum, papill...
Concrete is an essential building material which is widely used in construction industry all over the world due to its compressible strength. Curing of concrete plays a vital role in durability and other performance necessities. Improper curing can affect the concrete performance and durability easily. When areas like scarcity of water, structures is not accessible by humans external curing can...
OBJECTIVE The aim of this study was to determine the effects of light intensity and type of light unit (quartztungsten-halogen [QTH] or light-emitting diode [LED]) on the hardening of various resin cements and a resin composite restorative. METHODS Disk specimens were prepared from 4 dual-cured resin cements (Variolink II, Calibra, Nexus 2 and RelyX ARC). Two QTH light-curing units (Visilux 2...
