Formation and aggregation of metal carboxylates (metal soaps) can degrade the appearance integrity oil paints, challenging efforts to conserve painted works art. Endeavors understand root cause soap formation have been hampered by limited spatial resolution Fourier transform infrared microscopy (μ-FTIR). We overcome this limitation using optical photothermal spectroscopy (O-PTIR) photothermal-induced resonance (PTIR), two novel methods that provide IR spectra with ≈500 ≈10 nm resolutions,...
<div class="section abstract"><div class="htmlview paragraph">Due to advantages such as high efficiency, low emissions, and fuel flexibility, solid oxide cells (SOFCs) have garnered significant attention promising power sources for automotive applications. Nickel/yttria-stabilized zirconia (Ni/YSZ) is one of the most widely used anode materials in SOFCs, it can catalyze both chemical electrochemical reactions carbon-containing fuels. However, direct use fuels lead carbon...
Oil paints comprise pigments, drying oils, and additives that together confer desirable properties, but can react to form metal carboxylates (soaps) may damage artworks over time. To obtain information on soap formation aggregation, we introduce a new tapping-mode measurement paradigm for the photothermal induced resonance (PTIR) technique enables nanoscale IR spectroscopy imaging highly heterogenous rough paint thin sections. PTIR is used in combination with μ-computed tomography microscopy...
Abstract Lime mortars have played an important role in constructing ancient Chinese masonry structures, including city walls, buildings, and tombs. A tomb built with lime stones belonging a Ming high‐ranking official, Xu Jie, was discovered Huzhou City of China. Eight different samples from Jie’s tomb, representing four types lime‐mortar‐based materials: joint mortar between stone bricks, bedding mortar, grouting plaster were collected for analysis comparison. The characterization the...
With the development of China's economy, protection and conservation ancient buildings were put on agenda. However, current understandings Chinese traditional mortars are limited rarely reported in literature. In this article, authors investigate seven city wall sites built during Ming Qing dynasties (1368–1841 AD) situ, subsequently laboratory analysis carried out collected mortar samples. The characterizations samples performed using digital microscopy, scanning electron microscopy (SEM),...
This paper focuses on the characterization of materials from fragmented pieces an imperial lacquer plate in Luozhuang Han tomb, which dates to early Western dynasty. Various non-invasive and minimally invasive techniques were performed, including optical electron microscopy, XRF, Raman spectromicroscopy, FT–IR, XRD THM-Py–GC/MS. The lacquerware consist a five-layer structure, includes (from top): red pigmented layer, two finish layers, ground layer canvas/wood foundation layer. consists...
The Yuzhen Palace is one of the nine palaces in Ancient Building Complex built by order Yongle Emperor during Ming dynasty. buildings were with dressed black bricks. As a result planned national South–North Water Diversion project, water level Danjiangkou Reservoir that surrounds was expected to rise approximately 15 m. To avoid submersion site, three gates elevated m 2013 and other dismantled, for later reconstruction. characterization construction materials has therefore become primary...
For centuries, the architecture of Palace Museum represented highest standard Chinese architecture. The Yangxin consisted 18 masonry buildings built using bricks, wood, roof tiles and various mortars. In 2016, a five‐year project was initiated to work on maintenance restoration buildings. characterization construction materials has become primary importance, in order obtain information about raw ingredients building technology mortars, history possible previous restorations. this paper, 12...
