New Method For Determination Of Molecular Orientation At Interfaces

Sum frequency generation spectroscopy (SFG) is a technique used to analyze surfaces and interfaces. This nonlinear laser spectroscopy method can deduce the composition, orientation distributions, and some structural information of molecules at gas–solid, gas–liquid and liquid–solid interfaces. In a typical SFG setup, two laser beams mix at a surface and generate an output beam with a frequency equal to the sum of the two input frequencies. SFG has advantages in its ability to be monolayer surface sensitive, ability to be performed in situ (for example aqueous surfaces and in gases), and not causing much damage to the sample surface. SFG is comparable to second harmonic generation in Infrared and Raman spectroscopy. It is a challenge to measure orientation heterogeneity. For decades, surface-specific vibrational sum frequency generation spectroscopy (referred to as 1D VSFG hereafter) has been used to determine the mean tilt angle, under the assumption of a narrow orientational distribution. However, in this case, the knowledge of orientational distribution is lost, and the measured mean tilt angle can deviate from the real mean tilt angle when the orientational distribution is large, which is the well-known “magic angle” challenge.

A Micro/Nanobubble Oxygenated Solutions for Wound Healing and Tissue Preservation

Soft-tissue injuries and organ transplantation are common in modern combat scenarios.

Graphen Layer Formation On A Carbon Based Substrate

Background: Plastics are cheap, durable, light-weight and have a wide range of practical applications. Despite its universality, plastic materials suffer from low thermal conductivity that limits them from many other uses. Graphene has many remarkable properties, that in conjunction with other materials, can enhance their functionality and usage in various market segments. The graphene market is projected to reach $200M by 2026. Brief Description: UCR researchers have developed a novel system and method for forming graphene layers on a substrate. The system allows for direct growth of graphene on diamonds and low temperature growth of graphene using a carbon source. Due to the various novel features of the system, one can make the most of graphene’s excellent intrinsic thermal conductivity by substantially improving the radio frequency characteristics. Thermal conductivity can be strengthened by adjusting the size and alignment of the graphene flakes.

Low-variability, Self-assembled Monolayer Doping Methods

Semiconductor materials are fundamental materials in all modern electronic devices. Continuous demand for faster and more energy-efficient electronics is pushing miniaturization and scaling to unprecedented levels. Controlled and uniform doping of semiconductor materials with atomic accuracy is critical to materials and device performance. In particular, junction depth and dopant concentration need to be tightly controlled to minimize contact resistance, as well as variability effects due to random dopant fluctuations in the channel. Conventional doping methods such as ion implantation is imprecise and can have large variability effect. Moreover, energetic introduction of dopant species will often cause crystal damage, leading to incompatibility with nanostructured-materials and further performance degradation. To address these problems, researchers at the University of California, Berkeley, have experimented with an alternative approach to a wafer-scale surface doping technique first developed at the UC Berkeley in 2007. The team has demonstrated a controlled approach for monolayer doping (MLD) in which gas phase dopant-containing molecules form low-variability, self-assembled monolayers (SAM) on target semiconductor surfaces.
