Integrated Flexible Filter Photodiode Array For RGB Detection

Inorganic-semiconductor-based photodiodes (PD) have a broadband photoresponse in the visible range.  There are a few approaches to achieve color images with broadband PDs.  The most common one involves the use of a color filter array (CFA) placed over the sensor. Bayer filter, a mosaic of red (R), green (G) and blue (B) filters is the most common color filter array.  In the contrast to inorganic PDs, the main approach to achieve color images with organic photodiodes (OPD) is to narrow the spectral selectivity of the pixels by tuning the absorption spectrum of the photoactive layer.   UC Berkeley researchers have developed an integrated flexible filter photodiode array for RGB detection, using a novel pixel concept and a new filter-substrate-OPD configuration to produce an all-printed full-color OPD imager.  In this approach both sides of flexible substrates are used to combine a broadband OPD and two wide range absorbing filters.  The filter-substrate-OPD configuration utilizes the substrate as a physical separator between the single-photoactive layer OPD array and the filters.   Another feature of current designs of RGB photodiodes is that the filters can be located above the photodiodes, deposited from the same side of the substrate as the photodiode or a completely separate system.  For example, in inorganic photodioes the filters are typically located over the photodiodes.  In organic photodiodes the filters are deposited from the same side of the substrate as the photodiode (e.g., in between the photodiode and the substrate) or a completely separate system.

Printable Repulsive-Force Electrostatic Actuator Methods and Device

Flexible electrostatic actuators are well designed for a range of commercial applications, from small micro-mechanical robotics to large vector displays or sound wall systems. Electrostatic actuation provides efficient, low-power, fast-response driving and control of movable nano-, micro-, and macro-structures. While commercially available electrostatic actuators have the requisite high levels of mechanical energy / force for some applications, their energy requirements are typically orders of magnitude higher than what is needed in large-area, low-power applications. Moreover, conventional approaches to these types of electrostatic actuators have limited design geometries and are prone to reliability issues like electrical shorts. To address these problems, researchers at the University of California, Berkeley, have experimented with planar electrostatic actuators using novel printing and electrode patterning and engineering techniques. The team has demonstrated a repulsive-force electrostatic actuator device (100 mm x 60 mm achieved) with extremely high field strength and high voltage operation and without insulator coatings or air breakdown.

Synthesis of Lipobactins and Teixobactin Analogues – New Antimicrobial Compositions against Gram-Positive Bacteria

With the discovery of penicillin in the 1940’s, many scientists proclaimed the defeat of infectious diseases which had plagued mankind. However, the remarkable healing power of antibiotics unfortunately invited widespread and indiscriminate use of antibiotics. This misuse and overuse of antibiotics has led to the dramatic rise in antibiotic resistant bacterial strains and increased healthcare costs.

Atom Probe Tomography Method and Algorithm

Most cluster analysis parameters in atom probe tomography (APT) are selected ad hoc. This can often lead to data misinterpretation and misleading results by instrument technicians and researchers. Moreover, arbitrary cluster parameters can have suboptimal consequences on data quality and integrity, leading to inefficiencies for downstream data users. To address these problems, researchers at the University of California, Berkeley, have developed a framework and specific cluster analysis methods to efficiently extract knowledge from better APT data. By using parameter selection protocols with theoretical explanations, this technology allows for a more optimized and robust multivariate statistical analysis technique from the start, thus improving the quality of analysis and outcomes for both upstream and downstream data users.

Dry-Eye Formulation

The sensation of ocular discomfort commonly referred to as “dry eye” can be caused by various factors. The principal causative factors are (a) increased tear-evaporation rates attributable to meibomian gland dysfunction and insufficient/unbalanced tear-lipid films; (b) inadequate tear-aqueous production attributable to aging, medical procedures performed on the cornea (e.g., LASIK), or other general health conditions (e.g., autoimmune diseases); (c) environmental irritants (e.g., dust, smoke, wind, sun, or low humidity); and (d) eye strain attributable to extended viewing of computer monitors or other working environment-related factors. There are many different artificial-eye drops marketed and prescribed or recommended by medical practitioners to decrease dry-eye sensations. Unfortunately, all provide only short-term or no effects at all on tear-film stability and evaporation rates. Moreover, many artificial-tear formulations contain petrochemicals, (e.g., mineral oil) which have nothing in common with natural lipids comprising human tear-lipid films and might be potentially harmful to the eye.   Researchers at UC Berkeley have developed bicontinuous microemulsion formulations capable of delivering the components necessary to counteract compromised stability of tear-lipid layers and thus enhance the stability of entire tear films. These bicontinuous microemulsion components disperse spontaneously into a physical state that makes the microemulsion completely miscible with both human tear aqueous and human tear lipids. The components of these microemulsions are chemically identical or very close to natural tear lipids and tear aqueous and thus are completely biocompatible with human tear films. The lipids used in this formulation are biodegradable, and human tear enzymes will be able to metabolize these bicontinuous microemulsion lipids.
