Ultrafast Laser Synthesis of Zeolites
Advanced Materials, EarlyView.The study presents a novel ultrafast laser‐driven synthesis technique for zeolites directly in liquid. Laser pulses create a microscopic reactor that controls reaction kinetics at femto‐ and picosecond timescales. Nonlinear light‐matter interactions drive nucleation and growth, allowing the process to be paused at any stage of self‐assembly.

A Cosmological Fireball with 16% Gamma-Ray Radiative Efficiency
The Astrophysical Journal Letters, 2023 Gamma-ray bursts (GRBs) are the most powerful explosions in the universe. How efficiently the jet converts its energy to radiation is a long-standing problem, which is poorly constrained.

Rapid Bursts From GRS 1915+105 with RXTE [PDF]
, 1997 The light curves of GRS 1915+105 observed with RXTE on October 15, 1996 reveal a wide range of transient activity including regular bursts with a recurrence time of about 1 minute, irregular bursts, and dips. In contrast to bursts from other sources, a secondary (and a tertiary) weaker burst immediately following the primary burst are observed ...

Supernovae and Gamma-Ray Bursts [PDF]
Chinese Journal of Astronomy and Astrophysics, 2006 I review the observational status of the Supernova/Gamma-Ray Burst (GRB) connection. Available data suggest that Supernovae (SNe) associated with GRBs form an heterogeneous class of objects including bright and faint hypernovae (Hyp) and perhaps also `standard' Ib/c events.

Characteristics of type III radio bursts and solar S bursts [PDF]
, 2018 The Sun is an active source of radio emission which is often associated with the acceleration of electrons arising from processes such as solar flares and coronal mass ejections (CMEs). At low radio frequencies (<100 MHz), numerous solar S bursts (where S stands for short) and storms of Type III radio bursts have been observed, that are not directly ...

Gamma-ray Bursts and Afterglow [PDF]
Symposium - International Astronomical Union, 2000 The origin of GRBs has been a mystery for almost 30 years. Their sources emit a huge amount of energy on short time scales, and the process involves extreme relativistic motion with a bulk Lorentz factor of at least a few hundred. In the last two years, “afterglow” emission in X-ray, optical, IR, and radio was detected. The afterglow can be measured up
