Simple Solution Plasma Synthesis of Ni@NiO as High-Performance Anode Material for Lithium-Ion Batteries Application.

Pursuing of straightforward and cost-effective methods for synthesizing high-performance anode materials for lithium-ion batteries is a topic of significant interest. This study elucidates a one-step synthesis approach for a conversion composite using glow discharge in a nickel formate solution, yielding a composite precursor comprising metallic nickel, nickel hydroxide, and basic nickel salts. Subsequent annealing of the precursor facilitated the formation of the Ni@NiO composite, exhibiting exceptional electrochemical properties as anode material in Li-ion batteries: a capacity of approximately 1000 mAh g, cyclic stability exceeding 100 cycles, and favorable rate performance (200 mAh g at 10 A g).

Is cancer biology different in older patients?

Roughly 50% of cancer cases occur in people aged 65 years or older. Older people are often diagnosed at a later stage and might receive less (intensive) treatment, which might affect the outcome. In addition, an older age might be associated with biological differences in tumour and microenvironment behaviour, a domain that has been poorly studied so far.

Role of charge accumulation in guided streamer evolution in helium DBD plasma jets.

Experimental data are presented on the evolution of a helium atmospheric pressure plasma jet driven by a tailored voltage waveform generated as bunches of voltage pulses consisting of a superposition of [Formula: see text] kHz bipolar square pulses and [Formula: see text] kHz oscillations. The characteristics of directed ionization waves (guided streamers) are compared for bunches with different first pulse polarities and different bunch duty cycles. The longest and brightest streamers are achieved at the voltage bunch with the first negative pulse and a minimum duty cycle.

[State of cellular and humoral immunity after soft tissue endoprosthesis implantation and correction of body forms using biogel Interfall].

Injection implantation of polyacrylamide gel "Interfall" in soft tissues was conducted in 110 patients in 1992-1997 yrs. In 17 patients the mammary glands prosthesis was conducted using biogel. Biogel did not influence the cell subpopulations of the immunity T- and B-systems, the immunoglobulins level and did not cause the organism sensibilization.

[Preoperative antibacterial therapy in the comprehensive treatment of patients with external biliary fistulas].

The experience with antibacterial therapy in 120 patients with choledocholithiasis and cicatricial stricture of the bile ducts complicated by the development of an external biliary fistula is summarized. It was established that intravenous administration of antibiotics at the maximum dosages with purposeful sanation of the bile ducts via the external biliary fistula at the preoperative period improved the immediate and long-term results of treatment of the patients. Only in full-value, adequate correction of disorders in the major bile outflow, the reliable elimination of the external biliary fistula is possible.
