June 14, 2016 – As part of our ongoing mission to enhance our technical support in Asia and to support our rapidly growing sales and innovation in China, we are proud to announce the addition of Dr. Rory Chen.

Dr. Chen earned his PhD from Freie Universität Berlin Germany, Department of Physics (Research group of Prof. Katharina J. Franke).  His dissertation research was on “Structural, Electronic and Switching Properties of Metalloporphyrin Molecules on Metal Surfaces a Combined STM and AFM Study”

“The addition of Dr. Rory Chen further strengthens our wonderful team in China while offering additional support to our users across Asia.  Dr. Chen has extensive experience in UHV SPM.  We look forward to him being an excellent resource to our rapidly-growing customer base in Asia”, said Adam Kollin President of RHK.

”As one of the largest research instrumentation distributors in the world, Quantum Design is pleased to have a longstanding cooperation with RHK Technology in the Asian market since 2008.  We are glad to see the exciting increase of sales in our territory.  Through our ongoing effort of building a strong local support team, we aim to deliver faster and better service to our customers and our partners”, said Lambert CAO General Manager of Quantum Design China

RHK Technology, Inc., the innovation leader in cryogen-free scanning probe microscopy (SPM) and SPM control systems enables research in major universities and government laboratories around the globe. RHK is based in Troy, MI, USA. www.rhk-tech.com

Figure 1: Zoomed 5 nm image. Using Fourier filtering of the larger raw image, the superlattice is removed, and only the crystal lattice remains. Specifically, in filtering, we selected all of the crystallographic Bragg peaks connected by reciprocal lattice vectors appearing in the FFT. (PHYSICAL REVIEW B 93, 045430 (2016))

We use scanning tunneling microscopy to study the lithium molybdenum purple bronze (Li0.9Mo6O17) at room temperature. Our measurements allow us to identify the single-crystal cleave plane and show that it is possible to obtain clean cleaved surfaces reflecting the crystal structure without the complications of nanoscale surface disorder. In addition to the crystal lattice, we observe a coexisting discommensurate superlattice with wave vectors q = 0.5a ± 0.25b. We propose that the origin of the superstructure is a surface reconstruction that is driven by cleaving along a crystal plane that contains in-plane MoO4 tetrahedra connected to out-of-plane MoO6 octahedra through corner-sharing oxygens. When combined with spectroscopic measurements, our studies show a promising avenue through which to study the complex physics within Li0.9Mo6O17.

STM image of D2O-covered step edges on Pt(553) [Tip type: cut and pull Pt/Ir; 4.5×4.5nm2; TSTM=25K; V=−1V , I= −9pA (Phys. Rev. Lett. 116, 136101)

The interaction of platinum with water plays a key role in (electro)catalysis. Herein, we describe a combined theoretical and experimental study that resolves the preferred adsorption structure of water wetting the Pt(111)-step type with adjacent (111) terraces. Double stranded lines wet the step edge forming water tetragons with dissimilar hydrogen bonds within and between the lines. Our results qualitatively explain experimental observations of water desorption and impact our thinking of solvation at the Pt electrochemical interface.
