Thermodynamic Bounds on Efficiency for Systems with Broken Time-reversal Symmetry

, 2011
We show that for systems with broken time-reversal symmetry the maximum efficiency and the efficiency at maximum power are both determined by two parameters: a "figure of merit" and an asymmetry parameter.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Optimization of quantum state tomography in the presence of experimental constraints

, 2014
In the absence of experimental constraints, optimal measurement schemes for quantum state tomography are well understood. We consider the scenario where the experimenter doesn't have arbitrary freedom to construct their measurement set, and may therefore

Thermoelectric performance of granular semiconductors [PDF]

, 2009
We study thermoelectric properties of granular semiconductors with weak tunneling conductance between the grains, g_t < 1. We calculate the thermopower and figure of merit taking into account the shift of the chemical potential and the asymmetry of the ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Considering the Figure of Merit as a parameter of optimization in Mammography: a case study of the performance in a CR and a DR system

Brazilian Journal of Radiation Sciences
Mammography is an important examination for the early detection of breast cancer, and its use requires radiation protection considerations to ensure the lowest possible risk to the patient.

Optimal thermoelectric figure of merit of a molecular junction

, 2008
We show that a molecular junction can give large values of the thermoelectric figure of merit $ZT$, and so could be used as a solid state energy conversion device that operates close to the Carnot efficiency.

Optimizing plasmonic nanostructures array for high-performance sensing applications

Results in Physics
The localized surface plasmon resonance (LSPR) phenomenon, influenced by the surrounding medium, has been widely employed in optical sensors. Traditional sensors focus on refractive index sensitivity (ηRIS) but neglect the broad spectral linewidth, thus ...

Combining antibody conjugates with cytotoxic and immune‐stimulating payloads maximizes anti‐cancer activity

Molecular Oncology, EarlyView.
Methods to improve antibody–drug conjugate (ADC) treatment durability in cancer therapy are needed. We utilized ADCs and immune‐stimulating antibody conjugates (ISACs), which are made from two non‐competitive antibodies, to enhance the entry of toxic payloads into cancer cells and deliver immunostimulatory agents into immune cells.
