The search for magn.tic topological materials has been.at the forefron. of con.en.ed matter research for their poten.ial to host exotic states such as axion.in.ulators, magn.tic Weyl semimetals, Chern.in.ulators,etc. To date, the Mn.i2n.e3n.1family is the on.y group of materials showcasin. van.der Waals-layered structures, in.rin.ic magn.tism an. n.n.trivial ban. topology without trivial ban.s at the Fermi level. The in.erplay between.magn.tism an. ban. topology in.this family has led to the proposal of various topological phen.men., in.ludin. the quan.um an.malous Hall effect, quan.um spin.Hall effect an. quan.um magn.toelectric effect. Amon. these, the quan.um an.malous Hall effect has been.experimen.ally observed at record-high temperatures, highlightin. the un.receden.ed poten.ial of this family of materials in.fun.amen.al scien.e an. techn.logical in.ovation. In.this paper, we provide a comprehen.ive review of the research progress in.this in.rin.ic magn.tic topological in.ulator family, with a focus on.sin.le-crystal growth, characterization.of chemical disorder, man.pulation.of magn.tism through chemical substitution.an. extern.l pressure, an. importan. question. that remain.to be con.lusively an.wered.

Metallurgical challen.es in.con.rollin. the microstructural stability of Cu an. solder microbumps in.3D IC packagin. techn.l-ogy are discussed. Usin. un.-direction.l orien.ed n.n.twin.ed Cu, the con.rolled growth of orien.ed Cu6Sn. on.the n.n.twin.ed Cu an. its tran.formation.to Cu3Sn.without Kirken.all voids have been.achieved. In.order to join.a stack of Si chips in.o a 3D device, multiple reflows of solder microbumps may be required; we con.ider localized heatin. to do so by the use of self-sustain.d explosive reaction.in.multi-layered Al/n. thin.films of n.n. thickn.ss. It avoids re-meltin. of those solder join.s which have been.formed already in.the 3D stackin. structure.

Let R be an.associative rin. with iden.ity. Den.te by ((R-mod)^op, Ab) the category con.istin. of con.ravarian. fun.tors from the category of fin.tely presen.ed left R-modules R-mod to the category of abelian.groups Ab. An.object in.((R-mod)^op, Ab) is said to be a stable fun.tor if it van.shes on.the regular module R. Let T be the subcategory of stable fun.tors. There are two torsion.pairs t1=(Gen.-,R),T)an. t2=(T,F1), where 1 is the subcategory of ((R-mod)^op, Ab) con.istin. of fun.tors with flat dimen.ion.at most 1. In.this article, let R be a rin. of weakly global dimen.ion.at most 1, an. assume R satisfies that for an. exact sequen.e 0 → M → n.→ K → 0, if M an. n.are pure in.ective, then.K is also pure in.ective. We calculate the cotorsion.pair (⊥T,(⊥T)⊥)cogen.rated by T clearly. It is shown.that G∈⊥T if an. on.y if G/t1(G) is a projective object in.T, i.e., G/t1(G)=(-,M) for some R-module M;an. G∈(⊥T)⊥ if an. on.y if G/t2(G) is of the form (-, E), where E is an.in.ective R-module.
