“…It has been shown more efficient to measure total thermal conductivity directly, than to predict the effect of changing one component. This was shown by Lorentzati et al [16], Alam et al [17], Chen et al [21], and Di et al [32]. In standard modelling thermal conductivity is separated into the following components, these dependent on underlying physical processes [27]:…”

“…However, cores analysed were composed of fibres with diameters ranging 1 -10µm, with performance loss significant in the 1-10 Pa region. Choi et al [21] researched fumed silica omission through VIP coating material alternatives, and inclusion of internal supporting pillars for shape maintenance. Using evacuated stratified glass fibre inter-separated with radiation shields as the core, and stainless steel coating, the measured central panel thermal conductivities were below 2 mW/m.K.…”

“…Although these performed at pressures below 10 4 Pa, pore sizes were significantly larger and caused rapid performance loss. Chen et al [21] tested the VIP thermal conductivity impact of super stratified glass-fibre used as the core material. Under pressures ranging 0.03 -10 Pa samples exhibited a commercially promising thermal conductivity range of 1.25-13.03 mW/m.K.…”

AbstractThis article investigates impact of substituting fumed silica with a cellulosic-crystal innovation in a commercial Vacuum Insulated Panel (VIP) core. High building performance demands have attracted VIP technology investment to increase production capacity and reduce cost. In building retrofit VIPs resolve practical problems on space saving that conventional insulations are unsuitable for. Three challenges exists in fumed silica: cost, low sustainability properties, and manufacture technical maturity. Cellulosic nano-crystal (CNC) technology is in its infancy and was identified as a possible alternative due to a similar physical nano-structure, and biodegradability. The study aim was to determine a performance starting point and establish how this compares with the current benchmarks. Laboratory cellulosic-crystal samples were produced and supplied for incorporation into commercial VIP manufacture. A selection of cellulosic-panels with core densities ranging 127 -170 kg/m 3 were produced. Thermal conductivities were tested at a pressure of 1 Pa (0.01 mBar), with the results compared against a selection of fumed silica-VIPs with core densities ranging 144 -180 kg/m 3 . Conductivity tests were then done on a cellulosic-VIP with 140 kg/m 3 density, under variable pressures ranging 1 -100,000 Pa (0.01 -1000 mBar). This investigated panel lifespan performance, with comparisons made to a fumed silica-VIP of similar core density. Manufactured cellulosic-samples were found unsuitable as a commercial substitute, with performance below current standards. Areas for cellulosic nano-material technology development were identified that show large scope for improvement. Pursuit could create a new generation of insulation materials that resolve problems associated with current commercial versions. This is most applicable in building retrofit where large ranges of domestic and commercial cases are marginalised from their construction markets due to impracticalities and high upgrade costs. This being a problem in multiple economies globally. Figure 3 with typical layer thicknesses [1,13].VIP thermal conductivities are five to ten times lower than commercial insulations, with the centreof-panel reaching 4 mW/m.K [3,4,14,16]. Albeit excellent performance, the technology is expensive with panel prices multiples of five to ten that of standard insulations [...

“…For nanocarriers, which include liposomes, polymeric nanoparticles, and various types of nucleic acid vectors, the drug carrier typically is conjugated to folate, usually through a PEG linker to overcome steric hindrance surrounding the FR on the cell surface (64)(65)(66)(67)(68). Among macromolecules, folate has been conjugated to protein toxins (69), antibodies (70)(71)(72)(73)(74)(75), polymeric drug carriers (76)(77)(78)(79)(80), and prodrug converting enzyme (81). Clinical translation activities, however, have so far been focused on low molecular weight (MW) folate conjugates and have been carried out at Endocyte Inc.…”

Abstract:Targeted drug delivery is a promising strategy for improving tumor therapy. Folate receptor (FR) is an established ovarian cancer marker that is also frequently found to be overexpressed in other major epithelial tumors. Meanwhile, functional FR−β is expressed in myeloid leukemias and in inflammatory macrophages, including tumor-associated macrophages. FR based tumor targeted drug delivery has been a very active area of research and recent advancement of this technology towards clinical translation is highly significant.

An effective film construction was provided as a noise‐reducing materials based on self‐assembled polymer film supported by ultralight glass fiber blanket (UGFB) skeleton. The synthesized polymer film enhanced UGFB structure shows about 60% improvement over a broad frequencies compared to neat UGFB. The sound transmission loss has a remarkably increasing of 16.59 dB at 4 kHz. The reinforced acoustic performances was created by the structural optimization of UGFB/UMPR‐film, owing to the observably enhanced tortuosity in sound waves transmission and reinforced surface area, which can induce more viscous and thermal losses when the acoustic wave consumes in the semiopen pore construction. Moreover, the UGFB/UMPR‐film demonstrates 7.4 times increasing in breaking strength (width direction) and the degrees of uniformity lower than 0.0771. The manufacture of this new acoustic damping materials is low cost, structural controllable, and easy to large‐scale preparation, making it can be applied in multitudinous applications.
