Synergistic Tailoring of Electronic and Thermal Transports in Thermoelectric Se-Free n-Type (Bi,Sb)Te.

Se-free n-type (Bi,Sb)Te thermoelectric materials, outperforming traditional n-type Bi(Te,Se), emerge as a compelling candidate for practical applications of recovering low-grade waste heat. A 100% improvement in the maximum of n-type BiSbTe is demonstrated by using melt-spinning and excess Te-assisted transient liquid phase sintering (LPS). Te-rich sintering promotes the formation of intrinsic defects (Te), elevating the carrier concentration and enhancing the electrical conductivity.

Contradicting Influence of Zn Alloying on Electronic and Thermal Properties of a YbCd Sb -Based Zintl Phase at 700 K.

Zintl compounds are promising thermoelectric materials for power generation as their electronic and thermal transport properties can be simultaneously engineered with anion/cation alloying. Recently, a peak thermoelectric figure-of-merit, zT, of 1.4 was achieved in a (Yb Mg )Cd Mg Zn Sb Zintl phase at 700 K.

Pharmacokinetics and efficacy of a biweekly dosage formulation of exenatide in Zucker diabetic fatty (ZDF) rats.

Purpose: To develop an improved sustained-release (SR) formulation of exenatide (a therapy for patients with type 2 diabetes mellitus) in a biweekly dosage form with therapeutic efficacy comparable to that achieved with twice-daily injections of the drug.

Methods: A SR formulation of exenatide, DA-3091, was prepared by single-emulsion solvent evaporation using poly(D,L-lactide-co-glycolide). Plasma exenatide, as well as plasma insulin, non-fasting blood glucose and HbA1c concentrations, and changes in food intake and body weight were evaluated in both Zucker diabetic fatty (ZDF) and ZDF lean control rats.

[The history of pharmacy in Korea].

The history of pharmacy in Korea from the era 'Dangun Mythology' to the present day was reviewed briefly with special emphases on the beginning of pharmaceutical education, the introduction of modern pharmaceutical education, the establishment of modern educational institutions, the evolution of a new 6-year pharmaceutical education program, and the separation of drug prescribing and dispensing.
