Enhancing the production of α-cyclodextrin glycosyltransferase (α-CGTase) is a key aim in α-CGTase industries. Here, the mature α-cgt gene from Paenibacillus macerans JFB05-01 was redesigned with systematic codon optimization to preferentially match codon frequencies of Escherichia coli without altering the amino acid…
INTRODUCTION: Aptamers hold great promise as molecular tool in biomedical applications due to the therapeutic utility exhibited by their target specificity and sensitivity. Although current development of aptamer is hindered by its probable in vivo degradation, inefficient immobilization on probe surface, and generati…
Ischaemia-related diseases such as peripheral artery disease and coronary heart disease constitute a major issue in medicine as they affect millions of individuals each year and represent a considerable economic burden to healthcare systems. If the underlying ischaemia is not sufficiently resolved it can lead to tissu…
This letter documents the design, microfabrication, and testing of integrated and continuously tuned radiofrequency copper (Cu) inductors with low-power large-throw lead-zirconate-titanate (PZT) actuators. The devices, with inductances in the 3-10-nil range, achieved high-quality factors, Q >; 10 (1-6 Gilz range), and…
We use dynamic scanning capacitance microscopy to image compressible and incompressible strips at the edge of a Hall bar in a two-dimensional electron gas (2DEG) in the quantum Hall effect (QHE) regime. This method gives access to the complex local conductance, G ts , between a sharp metallic tip scanned across the sa…
Hydrogel hydrophobicity is an important modulator of mammalian cell behavior, drug payload release, and medical device fouling. Contact angle and protein adsorption measures are two common methods for evaluating hydrogel hydrophobicity. However, protein adsorption is a complex phenomenon which is challenging to interp…
Abstract Zinc(II) complexes with dangling functional organic groups were synthesized by reaction of zinc acetate with a series of bifunctional p‐substituted benzene derivatives (a combination of carboxylate, oximate, amino, β‐ketoimine, and salicylaldime groups). Selective coordination to carboxylate groups was observ…
Silicon-based surface-plasmon subbandgap detectors integrated with an asymmetric metal stripe are investigated for different metals, modes, and wavelengths of operation. Low-order bound modes supported by Al and Au stripes cladded below by silicon and covered by air are studied at the infrared wavelengths of 1310 and…
Xanthophyllomyces dendrorhous is a natural source of astaxanthin, a carotenoid widely used in the food industry. In this yeast, astaxanthin is synthesized from β-carotene by a cytochrome P450, CrtS, which depends on CrtR, the four-domain cytochrome P450 reductase (CPR). Although Saccharomyces cerevisiae has an endogen…
Crystalline silicon solar cells are predominant and occupying more than 89% of the global solar photovoltaic market. Despite the boom of the innovative solar technologies, few can provide a low-cost radical solution to dramatically boost the efficiency of crystalline silicon solar cells, which has reached plateau in t…
We show that a helically grooved metal wire supports chiral surface plasmon polaritons (SPPs) that carry nonzero orbital angular momentum (OAM). This OAM can be tuned to have integer or fractional values by adjusting the mode wave vector. The dispersion relation and angular characteristics of the chiral modes are dete…
This work combines electrophoretic deposition (EPD) with direct-ink writing (DIW) to prepare thin films of Al/CuO thermites onto patterned two- and three-dimensional silver electrodes. DIW was used to write the electrodes using a silver nanoparticle ink, and EPD was performed in a subsequent step to deposit the thermi…
In this letter, we fabricated resistance random access memory in a Pt/GaOx/TiN structure with a bipolar resistance switching characteristic and a bistable resistance ratio of about two orders byI-Vsweeping. In order to increase the oxygen ion quantity in the gallium oxide layer, the proposed sample was sputtered in a…
The NIF neutron activation diagnostic suite relies on removable activation samples, leading to operational inefficiencies and a fundamental lower limit on the half-life of the activated product that can be observed. A neutron diagnostic system measuring activation of permanently installed samples could remove these li…
The structure of copper phthalocyanine (CuPc) thin films (5-100 nm) deposited on single-crystal ZnO(1100) substrates by organic molecular beam deposition was determined from grazing-incidence X-ray diffraction reciprocal space maps. The crystal structure was identified as the metastable polymorph α-CuPc, but the molec…
Cylindrical Ti-6Al-4V parts were built in vertical and horizontal orientations using electron beam melting. Tensile tests and fatigue tests were carried out. The specimens were tested in as-built and machined conditions to understand the effect of surface finish on mechanical properties. The fracture surfaces were ana…
A novel highly π-extended heteroacene with four symmetrically fused thiophene-ring units and solubilizing substituents at the terminal β-positions on the central ring, dithieno[2,3- d;2′,3′ -d ′]benzo[1,2- b;4,5- b ′]dithiophene (DTBDT) was synthesized via intramolecular electrophilic coupling reaction. The α-position…
Twin arginine transport (Tat) systems transport folded proteins using proton-motive force as sole energy source. The thylakoid Tat system comprises three membrane components. A complex composed of cpTatC and Hcf106 is the twin arginine signal peptide receptor. Signal peptide binding triggers assembly of Tha4 for the t…
Mapping the optical near-field response around nanoantennas is a challenging yet indispensable task to engineer light-matter interaction at the nanometer scale. Recently, photosensitive molecular probes, which undergo morphological or chemical changes induced by the local optical response of the nanostructures, have b…
Physical integration of a Ag electrical contact internally into a metal/substrate/microstructured Si wire array/oxide/Ag/electrolyte photoelectrochemical solar cell has produced structures that display relatively low ohmic resistance losses, as well as highly efficient mass transport of redox species in the absence of…
